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 !!!!

In the 1000km of testing completed to date the exhaust gas temperatures have not exceeded 880deg C. Completed a proper longer haul load test to top of 4th gear (8000rpm) to get the highest reading as well. Normally peak in 3rd is around 840deg C in a near static load condition. Front and Rear rotor read the same to 0.5 deg C.

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.

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.

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

Here is the finished camera mount got the position good same as what I had it before I think, she works great.





We are organizing/negotiating an air strip for some "official testing" will feature a video and FULL VBOX3i report soon.

I weighed the car right after the runs:

2,917 lbs (1323kg) without driver
3,113 lbs (1412kg!) with driver " (note 478bhp rated motor)

Car does 60mph to 85mph in ~2.10 seconds compared to RICESP 2.23 seconds *I need to turn the boost up just a little* ~5k to 7krpm for both vehicles. I estimate my thing has around ~440bhp on ~17psi setting, aiming for honest ~500 honest bhp on 1.5bar boost setting, which should achieve the goal of matching/beating? the F40. My power figure average for the SP is ~270rwkw on my VBOX measure (going off my experience * 1.2 = engine power = ~435bhp)

60mph to 85mph now is .......................... 2.11 seconds basically exactly equal to the USA F40 for which I have a VBOX test from an owner *above*Though his was on a small down hill gradient (so artificially fast in my book).
100-140kmh is 2.10 seconds 70.36 meters (EURO F40 apparently does 2.0 seconds and 67.60 meters but have only ever found one magazine test on that, fastest one ever recorded too btw) listed earlier on.

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.

^ Here is the video, I am so happy with it, its as fast or faster than every Ferrari F40 I have on file (bare one test), faster than a Pagani Zonda (VBOX file of that one!).

Get On It :-Oc==3

Here is the graph showing some detail of various parameters & performance. Average figures between test lines shown (Avg-b) *report screen* and peak on datum line of graph in top left box snapshot of instant Graph data figures at that point.

It is always interesting to see your work. Keep it up.

Thank you very much to you for giving us a dedicated platform to share knowledge & enthusiasm for H2O... so everyone can learn from our fore fathers who pioneered water injection, showing its unrivaled abilities to make copious amounts of power along with durability combined
