I finally, after alot of persuading, put my car on the dyno. The car is a Kouki s14 with an S1 Rb25 BPU.

I did 2 pulls and made 255hp and 251tq with 108 air temps, shop was hot as hell. The only problem I had was the 2 foot+ flames I was shooting out of the exhaust.

Now its time for upgrades.

Sounds like the ecu is pulling timing and adding fuel in an attempt to *save* itself. Time for a tune, not time for more upgrades.

your saying you have bpus so im assuming u have a walboro, pod filter, fmic, d/p 3" exhaust and maybe a boost controller

dont blow money on things you will not get the most power out of, tune first, then more mods

The car is a daily for now and pretty much came with everything except the boost controller when I got it. Upgrades would include tuning but I just got a really good deal on a 26 and I plan on swapping that in instead once I get another daily. I really just wanted to confirm that the engine was healthy before I tried to sell it. The dyno pulls where also on an uncorrected dyno jet when it was hot as hell and for some reason I could only get 10psi out of it on the dyno where as on the street I get 12~13.

Believe me, it has been a long road to get this car running right as it was super ghetto rigged when I got it. Right now, the car has an SAFC2 on it that is zeroed out...we're putting a wideband on it next weekend to tweak it just a little and then I'll prolly do nothing else to this engine until I'm ready to throw the RB26 in.
