Re: RICESP Water Injected RX7
Got a phone call this morning at 7.am from a friend inviting me to go to the local 1/8th mile drag track (owner of it was running in his rail flat head supercharged methanol V8!). Could not resists so I quickly hooked up my new car trailer and loaded the Mazda on and went there.
Got a chance to run my car down there and practice some launching techniques, the thing is unreal :) 1st gear taking off simply requires a bit of clutch slip to preserve the gearbox and differential, letting the thing fully engage at 3500rpm or so it got such a great spread of power that it just spins the tires all the way through first, second gear grips up and third it was pulling near 8000rpm at the end of the 200m (100mph or so). Took max revs to 8500rpm and the hard work on improving the mixture at the higher revs did help, my passenger commented that it just keeps on making power and theorized it should be able to pull to 9k rpm hahaha (I informed him that was not recommended or needed). He was totally amazed that a road car with full legal catalytic exhaust and moderate noise level on ~17psi boost accelerated so well. Riding in passenger seat he said in 3rd gear in last half of the track it feels as fast as his 6.7 second drag only 6cy turbo car, it was very hot today (maybe 30 deg C in the sun) on board power meter was showing 281rwkw @ 7700rpm. I took him for 3 runs back to back then did 3 or so on my own and it performed faultlessly. We have a drag event there on the 4th of April and am confident to show up and not make an arse of myself with a car that is too slow :) *I have VBOX tested his drag car, 36psi boost, methanol, 3300cc straight 6, tripple SU carb draw through turbo set up 1008kg car, making measured ~250rwkw 6.75 seconds @ 106mph in 200m test.* Will have to implement the launch control system and also use staged boost in the hope of trying to get some better take off's........ though its not really made for that kind of activity at the end of the day it was allot of fun regardless. Will have time to instrument the car before that event and will get the VBOX data of 0-100kmh times and other performance measures also. The traction control was too invasive on initial take off and since I had not configured the launch control yet I turned it off totally on today's tests, the one thing I did learn is the fitment of the new Ohlins suspension full cured the cars tendency to wheel hop on take off wheel spin, it just sits flat and you can modulate the throttle and wheel spin with zero wheel hoping which means reduced drive line stress. :) |
Re: RICESP Water Injected RX7
Did a 0-100kmh test today.
Bogged it badly, Launch Control was not working so on take off the Traction Control setting of 3800rpm minimum engine speed activated and for 0.5 seconds car just rolled on at a constant massive 10.90kmh :(, first to second shift was 0.620 seconds before it started accelerating again (did not use flat shifting feature) to be brutally honest it was an arse fest of an attempt!!! :( Got 5.39 seconds Have since re adjusted the TC setting and lifted minimum engine speed activation to 5000rpm (so motor wont cut out) and increased variable boost to speed setting from 0.8bar 1st gear, 1.0bar second gear) to 1.0bar first and 1.2 bar second. Hoping it will do ~4.0 second range or maybe crack a high 3 if I manage to perfect it. |
Re: RICESP Water Injected RX7
Got a chance to do a run today at 1335kg test weight (27deg C day). Redid a few setting (still no flat shifting) Start procedure was release clutch at 4500rpm *no slipping* bit of wheel spin and engine dropped down to 2800rpm.......... Managed 4.40 seconds for 0-100kmh time. (will post up a graph report when I can).
There is probably 1/2 a second in refining technique and also working out boost control, as it was quite low in 1st gear and mid way through 2nd gear (1st 6psi below 4k rpm & 2nd below 12.5psi under 6k rpm). Probably best to leave boost control at the 1.2kg setting and not using variable speed boost and let the traction control modulate the power rather than the boost controller as its much much faster and more precise. I can run 40kg less weight too reduce fuel 20kg and 20kg of spare tire, jack tools etc... Maybe high 3 sec is possible on road tires :) |
Re: RICESP Water Injected RX7
Looks like you are have great fun with all your hard work building this machine. Would like to see 3s with perfected launch - do-able on your car.

Here are the files, self explanatory really :)
http://img214.imageshack.us/img214/4278/0100kmh440.jpg Note full power not achieved in 2nd gear, in 3rd showed 273rwkw on VBOX and 276rwkw on power meter (as per averages to date) More detail of average power delivered, start RPM and drop down in 1st gear, showing car was not abused to get the time :).......... there is some more left there as can be seen, nothing some more fine tuning of settings and technique would yield. http://img715.imageshack.us/img715/1...00testload.jpg |
Re: RICESP Water Injected RX7
Road testing, or grippy track testing ?
I was recently racing on a local airfield ( smooth tarmac just ) and found MT DR's offered me more grip than their ET Streets ! 60fts were similar, but ET's were down 0.2-0.3 secs |

I am going to my local 1/8th mile drag track on the 4th of April and will see what its like there, and can also run it out to 160kph or 100mph and get that incremental as well (in safety) :) I was at the track on Wednesday but it felt slippery as, though I was taking off totally different slipping the clutch and it was building allot more boost in first gear at higher engine rpm (left it on 1.2kg setting on boost controller). *did not have time to fit VBOX gear due to short notice* 2nd gear on the drag track on 1.2 bar felt stronger than today and more grip, the traction control was activated on the highway test on applying power and release of clutch into 2nd gear for a short bit (you can see AFR spiking lean *fuel cut of TC* looking at graphic). I'm not really into that type of testing or performance I should say (its a bit too harsh on the car), but lots like to know the figures for comparisons to other types of road cars I suppose. |
Re: RICESP Water Injected RX7
Turned her up to 1.40kg/cm boost setting this morning (weather starting to cool down here 18 deg C). Was boost learning *automated thing on Blitz unit* and showing 1.44kg/cm @ 7000rpm....... car has no misfires and spins wheels hard in 2nd gear when tires are cold.
Did a 3rd gear accel run down mild hill near workshop and its starting to feel really strong in acceleration I think I will leave it alone now :) ~20psi boost (243kpa absolute on ECU log) is enough in this particular road going car. When time allows will provide updated figures/graphs as always, but should be around 300rwkw level on my VBOX equipment (whatever that is at engine take your best guess!) 300rwkw on my equipment in this running weight (1305kg this mornings test) is really starting to feel good. |
Re: RICESP Water Injected RX7
Bit more refinement and fine tuning 90-140 in 2.75 seconds
http://img243.imageshack.us/img243/8...275seconds.jpg Power curve, I trialed the race exhaust and it was poor, the car lost power V's running the street exhaust and it was hideously loud to make it even worse, exhaust system pressure was about 50% less and turbine inlet pressure was around 12psi on 17psi inlet manifold pressure, same AFR and Timing it had up to 30rwkw less, and the volume was double :shock: http://img534.imageshack.us/img534/4...idynosheet.jpg |
Re: RICESP Water Injected RX7
Past another durability milestone today, have the boost set to 1.33kg/cm (showing about 18psi on VBOX in logs). Tested the engine compression after 1000km running at this boost setting and its ~120psi region. I reset the WI mixture to 4 turns (increased over the high power setting to give more safety margin) and took out 0.5 degree of timing at this boost and around 3 deg at higher boost levels (yet to try the higher level). AFR is 11.1:1 and is a bit lower to increase knock resistance for higher duty power application on track V's a one off power check.
I decided to go richer *11.10:1 target* and higher boost as its far safer (cooler, less prone to fuel quality variation that can induce pinging) than aiming less rich for optimal power at a fixed boost range setting Power is ~280rwkw on average 90-140 times (over a spread of 6 separate tests) 2.82 seconds My next boost increment step is 1.53kg/cm or 1.5bar (21.75psi old money!) When the weather gets cooler I will do that last step (haha for now till the next goal!) I am very happy with the power now and the way it goes "it flat out hauls" :) so am in no rush to step up to the next point............ but it would be nice to have over 300rwkw on my VBOX measure, but all at the expense of drive line durability let alone other parts so I will try to refrain from pushing more. |
Re: RICESP Water Injected RX7
Yesterday a customer of mine with 100% water injection set up, this is one of my old systems fitted to a 12A (running cosmo top intake manifold!) Rotary street port running 18psi boost pressure.... (see non adjustable atomizer fitted in bottom left of pic).
http://i282.photobucket.com/albums/k...o/CIMG0039.jpg He dyno'd 478hp @ the hubs on a dynapack chassis dyno = around 550bhp using the conventional 1.15TCF these specify. |
Re: RICESP Water Injected RX7
Just a summary, now I have settled on 4 turns setting on my RRWEP110 atomizer = 555cc/min & 11.1:1 AFR, its around 25% W/M to Fuel ratio at maximum power, higher percentage at lower rpm's.
Needed some safety factor against any unstable combustion to cover all situations. Have it permanently set on 1.33kg/cm boost. Took some adjustment of fuel tables to give target AFR from 2000rpm to 8000rpm. *listed below from my earlier post/tests* o.k. here is an update with more specifics as done so far, cause I am very familiar with my cars feeling and acceleration and have on board power measures as well I decided to do some longer term testing in all conditions to make sure its reliable before I go and hook up my VBOX and make an official comparison to the base I posted before. Parameters: 1.20kg/cm boost, no fuel map to timing adjustments 1000km running of these various settings equally distributed. Water flow rate 2.5 turns setting 404cc/min = good power feeling 11.3:1 AFR Water methanol 50/50 3.0 turns setting 462cc/min = better power than pure water 10.9:1 AFR Water methanol 50/50 2.5 turns setting 404cc/min = best power so far (car feels strongest of all combination's trialed) 11.1:1 AFR So I have decided to settle on the last setting, there is no knock and the engine restarts :lol: and its in one piece :lol: General feeling is the car is fast (which is good) so from this point I will do a more thorough analysis and comparison of the performance. |
Re: RICESP Water Injected RX7
I love those minute details, makes very interesting readings. Can you post some logs on the AFR on each gears - one of the more difficult target to achieve.

I ended up trying various other settings 4 turns, 3.5 turns, now back to 3 turns. The reason for this was I was on 2.5 turns for a long time and had the slightest amount of pinging after one test, car was restarted after being hot (sitting for 30 minutes) and all intake manifolding stays hot and on a 3rd gear pull it indicated very minor knock. I ended up changing fuel supply from Shell to BP, reduced some timing, increased some W/M mixture and have not been able to replicate the condition again. Power was back to 273rwkw and 90-140 times in 2.76 seconds on 4 turns out ~11.1:1 AFR. So now went back to 3 turns setting removed a tiny bit of fuel at 7500rpm to 8000rpm and I think its all finally set@! So much work to fine tune it all, stupid amount really... don't want to be doing it again in a hurry. I am taking the car to race it at the World Time Attack Challenge in 10 days time, I'll have plenty of logged track data then hopefully. On the way back if I have time I will put it on my friends Dyno Dynamics dyno at this current 1.3bar boost setting and see what it puts out on that system too. Peter |
Re: RICESP Water Injected RX7
Little update on the world time attack challenge.
I did not do too well personally only getting in 5 laps before the brakes decided to not work on my own car (things happen!) but on a much more positive note a Mazda RX7 fitted with my RRWEP110 Water Injection system totally dominated the open class (rotary runners)! over 4.4 seconds faster than the next mega dollar (money wasted?) kiddie internet special wanker specification car LOL. To add insult to injury for the car that got totally decimated by the water injected one it had an EPIC engine failure (3 day old $10,000 engine build!).... just goes to show internet knowledge and shit talk does not equal engineering experience on making rotaries reliable and fast no matter what fuel type you decide to run. Both cars were running E85 fuel. When I got home I have another E-Mail from a 6 cylinder friend who has run another pre turbo RRWEP110 kit on a customers car and on 25psi T51 turbo they managed 705rwhp through a standard automatic transmission, car is driven to drag track and does 10.5@136mph on radial street tires, over 10,000km running on the standard engine block *impressive* When I get a chance I will upload some pictures of the cars. p.s. My car was running exactly *on VBOX* 273rwkw @ 18.5psi boost when run at this track so the power was very consistent, engine was perfect, just need to sort out my brakes and will be back out and show what a real reliable road set up can do. |
Re: RICESP Water Injected RX7
This is a very exciting news, I bet you will more watert injected car in the next race. There is no better than the incylinder cooling effct of water when you are are under extreme racing conditions.
The WRC is a fine example of using WI. Highly stressed engine, lack of road speed. It has been used for a good 11 years until some guy in grey suit decided to ban it to save a few dollars. Get the brakes and show them what you can do with sound engineering and water injection. |

Re: RICESP Water Injected RX7
Been stupidly busy with work to post up here, sorry WI fans :)
Car is in same basic configuration, I have replaced my EGT sensors with *Inconel 600* encased versions since the SS316 ones were not durable enough past 40 hours. Sorted out the brakes :) & changed some specifications of various other misc parts (nothing fancy just some plumbing). Keen as to get out and do some more testing, Spring time here tomorrow (though we cant really say its ever Winter here!) :) |
Re: RICESP Water Injected RX7
Yes, no more cracks. But mega bucks.
SS310 is a cheaper alternative. |
Re: RICESP Water Injected RX7
Probes tested and fitted up, interesting note they 100% read lower than the much thinner exposed types I was using before (I estimate around 50deg C for same conditions with bench tests) will confirm in car in next week or so.
New mods and set up looks great :) fixed up all the little details I wanted to do since the major re-engineering of the initial set up :) she should be a rocket! I'll post up all the performance statistics sooner rather than later I hope........ I can't wait. The Ferrari F40 is going down !!!! :) |
Re: RICESP Water Injected RX7
Drove her today :) its sweeter than a fat chic molesting a bucket of KFC!
Little louder at cruise with new turbo, runs better, cooler, fixed the hot start "clicking" *boiling near thermostat* due to wrong water line mountings in first install :o21: New EGT probes are sweet too.

Re: RICESP Water Injected RX7
Here is some preliminary information comparing two different specification (turbine section) Turbochargers.
1.00A/R Garrett T04Z (from circuit test) RRWEP110 = 3 turns 266 rwkw @ 6950 rpm AFR 11.35:1 Boost 18.45 psi Turbine inlet pressure 17.1 psi Exhaust pressure 4.06 psi Turbo speed 101803 rpm 90kmh-140kmh = 3.05 seconds (flat track) EGT = failed probe after 35 hours (was around 1000 or so at lower boost and power) modified turbine specification (today run) RRWEP110 = 4 turns 268 rwkw @ 7250 rpm AFR 11.0:1 (1.7 degrees less timing) Boost 16.72 psi Turbine inlet pressure 14.43 psi Exhaust pressure 4.03 psi Turbo speed 101000 rpm 90kmh-140kmh = 3.25 seconds (10% incline rose 9m in 100m of test) *minus the incline these times are net equal from my experience* EGT Fr 875 deg C EGT Rr 885 deg C I wanted to be careful so I richened up the car and also took a few percent off the timing, the fueling curve is not optimized like it was on the smaller turbo, I have refined the mapping and also have reset the boost controller so it can learn the pattern of the new turbo from scratch then it will on a flat road perform better in like conditions to the 1.00A/R set up. Car has more top end pull as is and when the boost learns the loss down low will be marginal. You can see from the figures, that the Exhaust pressure *indicator of mass flow* is near identical for them both so this is one of my many cross checks to make sure no spurious figures are around, also the Turbine RPM is basically the same as well though this turbo has an aero nut V?s the other which when rebuilt had only a normal hex nut (whatever if any difference that makes lol). The Turbine inlet pressure is definitely less as you can see from the figures and despite the non optimized tune up it makes the same power and at high rpm so the engine is less restricted by this exhaust housing (which matches with the theory 100%) the car on power is QUIETER with this set up *unless I am on drugs* my theory on this is because less mass flow is going out the waste gate pipe (more through the turbine) and this must be making the car less noisy at full power as all other things are exactly the same from last time. I have reset the boost controller to learn 1.35kg/cm which equals 19.2psi, with the slightly tweaked set up (back to original timing) half turn less on RRWEP110 injector (down from 4 full turns) and tidied up spots in rpm range to give perfect AFR line (target 11.2:1 to 11.3:1 AFR) it *should* get to around 290rwkw on my VBOX measure (this is like 319rwkw on homo dynamics?)????.. anyway hope I have not bored you to death!!!!!!!!!!!!!!!!!! When I get around to driving it again will see what she does, should not be long as I have all the VBOX gear fitted in her so it?s just a matter of driving it. My best 90kmh to 140kmh time is 2.75 seconds at lower fuel load, flat road, (18psi average boost) and non heat soaked engine. |
Re: RICESP Water Injected RX7
Boost re-learn at 1.35kg/cm
3rd gear pull from 2500rpm = 1+ bar or ~15psi boost by 4300rpm 4th gear pull from same revs = 15+psi by 3600rpm[/i] VBOX3i results (on boost learning) max boost at this stage was like 1.25kg/cm or about 17.2psi 90-140kmh = 2.88 seconds, showed 272rwkw on Blitz power logging at 6800rpm and same power on my VBOX dyno plot (272rwkw @ 7000rpm) Repeated same test in exact same location as the small incline (so I could overlay graphs and see difference to flat piece of road and it ran 3.07 seconds (v?s the 3.25 yesterday) exact same vehicle weight (cross checked on corner scales this morning ).. AFR on these pulls was 11.1 to 11.0 across the range all smoothed out and boost was pretty similar to the first run where I did the comparison for you.. so trim of fuel mixture helped the time improvement. So after lunch I poured over the data and did some more trimming (2% reduction of fuel map) and went for a cruise. I gave it a few hits and it felt unreal in 2nd gear :auto: and partially in 3rd as well, on the way back on a nice stretch I pulled out to pass 3 cars and gave it the jandle from 3000rpm to 8000rpm and it was so strong! Stronger than a fat slut bench pressing buckets of KFC!!! The on board power meter showed 298rwkw @ 7200 rpm and held over 280rwkw to 7800rpm with don mega mid range power too. Boost was 1.35kg/cm or 19.2psi on the Blitz dyno graph log at these revs. So another 0.10kg/cm boost and a small fuel trim (along with refitting my old ignition timing map) made all the difference, oh and I turned the RRWEP110 down to 3.5 turns. AFR across board from 4000rpm to 8000rpm (75kpa to 140kpa gauge boost) is ~11.2:1 +-0.1. I?ll wait for a cool morning and take out the 20kg worth of spare tire, tools, fire extinguisher! And run it at ? tank of fuel and I should beat my 2.75 second 90-140 record. As a side note when I was at track and it was doing 90-140 in 3.05 second range, I did 100kmh to 200kmh in 8.1 to 8.2 seconds range at same weight (1350kg total). I?ll hope to do this in 7 seconds flat now as now I can hold 4th gear due to the much better top end power with no loss of 4700rpm to 7100rpm power range (as measured in the 90-140 tests in 3rd gear). It?s a win mate. Best power yet (nice increase with detail turbo<turbine modifications), much better power band to suit gearing with no loss of mid range at all. When the opportunity presents I'll do a full performance test and post up the information :) |

Re: RICESP Water Injected RX7
I did about 300km in it last week :) *covered ~5000km in past year*.
each time I wash the car I try for every second/third wash to do the engine bay, just a bit of extra work and shamy it dry after I do the body work (with its own shamy I use on the wheels). I do love the car, its been a long term project of mine (for last 6 years) and now I am very happy with it, by no means is it perfect or a show car in anyway but as an all rounder that I 100% built and tuned myself that is near my performance goals it brings me much joy :) Today I ordered some new spark plugs from Japan (different heat range). Last week I also procured a new set of springs for the waste gate valve, although its fully electronically controlled I am setting on a new higher boost base setting and the increase in mechanical spring will be of benefit. Also finishing off a part I wanted to do on the oil system, and some final settings on the RRWEP110 for the latest specification of the engine set up *Higher Performance Setting* When I complete that (pending parts delivery) I want to do a proper write up summarizing all of the finer detail and the performance measures of it in this final stage. Till then I'll enjoy a nice weekend of driving ................... (try not to get engine bay too dirty!). |

On cruising on stoich fuel mixture setting or leaner the EGT is over 100deg C cooler than before (on old turbocharger specifications). Fuel economy is flat out amazing ! including regular performance tests I average around 10lt per 100km. |
Re: RICESP Water Injected RX7
Well :)
Fitted up the new waste gate springs yesterday bought option of 1.3 bar and 1.4 bar Tail springs (combination of different inner and outers). I settled on the lower 1.3bar combo just in case they gave a higher set boost. Along with the new higher power setting I upgraded the specification of the spark plugs and some other details too. Took the "beast" out for a drive today and the boost went to 1.53 to average of 1.50kg/cm! which is around 1.47 to 1.50bar! or old money 21+psi boost :) .......... it pulls like a mother fucker! First 3 2nd gear acceleration runs just torches the rear semi slick tires to 8000rpm, after about 6 or more passes and a few 3rd gear pulls the rear tires got very hot and sticky and could "almost" use all of the extra grunt in 2nd gear (only in straight line though and perfect road surface).... third gear is just stupid and is over in a couple of seconds, its very fast now. Fuel duty before was around 67% > now 75% same AFR Power on the Blitz was just under 300rwkw Peak fuel pressure was 70psi now its around 75psi EGT peaks have not gone above 890deg C First cool morning will go out and do a test of the 90-140kmh and also do a 100kmh to 200kmh acceleration test report along with VBOX power graph. |
Re: RICESP Water Injected RX7
Boost learning procedure complete! 1.52kg/cm boost bro :) it is an animal :)
2nd gear just blows off the semi slick tires........... its unreal for a road legal 13B rotary set up, fastest most responsive true street set up 3rd gen RX7 I've ever been in. Making 305rwkw in my measure *estimate around 490bhp to maybe 500bhp @ std temp and pressure day* :) which was always an aim of mine. 90-140 test though not official time as VBOX battery gave up! *though it recorded the distance* was 85m. ~ 2.62 seconds. as a comparo 2.76 sec time covered in 88m and 2.82 sec time takes 90m. So its there ! on the ECU data speed sensor it shows ~2.5 seconds but this does not take into account wheel slip but its def legit...... Boost 130kpa (around 18.85psi) = 4400rpm 145kpa (around 21psi) = 5000rpm 144kpa held to 8000rpm AFR around 11.3:1 RRWEP110 set to 3.5 turns EGT 928 deg C and 930 deg C max Hope to have some graphs up sooner rather than later, but all this would NOT BE POSSIBLE without the power of WATER INJECTION!!!! Over 100 hours on this engine and its perfect too ;) |

Basically It's allot faster than the all but one of the Ferrari F40's listed *euro F40 Italian test, probably a boosted up special lol* (USA ones tested by Road and Track I obliterate in same rpm speed tests.) I have a video of it and will do up a VBOX report showing the boost, back pressure, EGT, Turbine speed, and all the shit I do...... its a very impressive car for what it is. Hiring an air port not far from me for some high speed testing and full performance review. If you compare it to the Domar Jap 500ps cars that cant char the semi slicks as hard as mine nor accelerate no where near as quickly its even more impressive. I love it. |
