Finally got my wastegate & boost leak situation sorted out and got back on the dyno friday.
The car was much different than the last run and made similar power at 7-8psi lower than last time on pump...which tells you something.
At 15psi, the S372 made 488whp & 355ftlbs on 91 octane.
At 32psi, on C16 i managed to made 779whp & 459ftlbs. This was near the limit of my current fuel setup. Datalogs show duty cycle on the 1600cc/min RC's to be around 85-90%. They are fed by an in-tank 255lph pump + an inline Bosch 044.
No runs were made the dyno at 36-40psi due to fuel shortage possibilities.

don t trust the duty cycle
r cars run on over 180%
at least that s what it says on the hondata

 

very nice congrats... now lets get some track times...

 

nice job! so with 4 more pounds than what my motor used with the T4/T67, you made 100 more hp. S372 is sick!

 

One of the OG turbo prelude guys still doing his thing! Glad to see it's still around dude!

Anthony and I have started talking about finishing mine...... won't be anywhere near as wild as yours, but at least I still have it! Glad I never sold it.....

Whats your goal for the car? Is this it? Are we going to see some track times anytime soon?

 

that nice

 

any pic????

 

Awesome! Are you still using stock cams? Head?

 

why that turbo spool so slow on that motor but nice power by the way

 

That turbo is as big as your head thats why...

NICE numbers..... 9500 on the H huh???

you need to get another bosch 044. the walbro just cant keep up

 

Pics of the setup and car please.

 

nice setup, another 044 would be better.

 

damn thats pretty sick! congrats.

 

That thing is a beast we need some pics .

 

I just actually took the car out to the track a few days ago after the last dyno run at 32psi hoping to put a 140+mph run in and get kicked off until i had a roll cage, etc.
Unfortunately my datalog shows that I made 36-37psi instead of the 32psi that the car was dynoed on. The bad news is I unfortunately found the limit of my fuel setup at a suboptimal time. Duty cycled showed 100% in 2nd and 3rd gear from 8800rpm up...and A/F went really lean even though the end columns had plenty of fuel. All this led to some motor damage which is yet to be explored (but plug 3 doesnt look good ).

I made it through 3 gears before i let off and coasted across the the 1000' and 1320', ending up with 123mph run anyways with very limited traction in 1 and 2 + a severe bog in 1st. (1st gear to 75kph 0-3.5sec, 2nd to 120 only took 1sec then 2sec until i hit third due to missed shift, 3rd gear 117kph to 168-170kph 2sec with wheelspin at top for additional second then 1-2seconds of 4th before i realized it was broken.) There is alot of room for improvement and traction + alot of power available + boost per gear tuning.

Any big horsepower guys out there offer me some opinions on my fuel setup and what u think will work good for 900-925whp. Advice needed.
(current setup is intank 255lph flowing through stock lines to a in-line 044 pump located below the firewall...then a -10 line to a AEM fuel rail feeding 1600cc/min RC injectors with a stock return).

I am putting together a video right now and hope to have it up tomorrow night.
