I just tuned my s2000 2002 whit a gt35r .63, whit a custom manifold, 3mm head gasket, aem ems, 3 inch full exhaust, brian crower stage2 camshaft, westgate 48mm turbosmart

i do on 91 octane 308 whp at 10 psi on a mustang dyno

please tell me something because i see people all the time on internet do like 400+ at 14 psi so im like what the hell im not gouing to do 400+ whit 14 psi its impossible but a lot off this people is on a dynajet dyno



thank you everybody to leave me a comment

Sorry for my english im from quebec city in canada and i speeking in french every day

 

Something has to be wrong. For 10 psi 308whp is really low. Who tuned your car?

 

Most likely the tune is terrible.

Only other thing aside from obvious things like boost leaks, etc, would be a poorly designed manifold but I highly doubt that.

 

dumb question but why does 10psi with the Greddy produce 300WHP, and thats not considered low for the Greddy. I thought Boost was Boost???????. I mean I understand the size of the Turbo, but wouldn't a larger turbo just produce more PSI, or am I way off?

thanks bro, makes sense

 

Also, the design of the Greddy manifold is not efficient.
The same applies to Inline log, which requires higher boost compare to tubular Lovefab for example.

 

I made 317 WHP with 6.8 boost with a SOT SC (dyno attached). This was on a dyno dynamics treadmill that is considered "tight" when it comes to its HP readings. I am guessing they are pulling tons of timing on your tune.

 

The Crower camshafts have been proven to LOSE power. Someone here lost 60 rwhp by installing the Crower camshafts.

 

Even then, with a 35r and the IP manifold, at 7psi I was making 320rwhp so I don't think its the manifold thats the problem (it looks like he has a tubular one anyway).

Tuner most likely.
