New 32psi dyno ... 780whp H22A/F20B Prelude
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

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?

Re: (93hatched_projekt)
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.
