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 ;) |
Re: RICESP Water Injected RX7
Here is the finished camera mount got the position good same as what I had it before I think, she works great.

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

Re: RICESP Water Injected RX7
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.

Re: RICESP Water Injected RX7
It is always interesting to see your work. Keep it up.
