Sounds really good, but I think you should be making around 600whp with a half BP and a GT42R? Is it the 102mm wheel?

EEk. But true.
Also, the video didn't need to show EVERY pull. I actually fast forwarded thru it.

At least you know it's well tuned by Steve Kan.

Yeah, you can see where he dumped the fuel and pulled the timing... It is safe though so that is good. What does 502whp on a dynapack equal on a dynojet?

I think its a 42-76. So the compressor is prolly a 76mm if thats what the turbo is. 102mm?? I hope your not talking about the compressor wheel. We are running a T6 manifold on our race supra (Boost Logic) and its a Precision 4288 which has a compressor wheel of 88mm.

I wouldn't complain about 503 hp but I expected more... only thing I don't like about those style dyno's is how quickly cars rev out.... I wanna hear it build boost! I'm kinda disappointed you put your exhaust back on too... lol

Nice man. I bet you are enjoying that car now huh? How well did those 1000cc primaries work out? I am about to get my Ultimate fuel kit tuned as well. Do you have one fuel pump or 2?

supposedly at least a 5% difference. on the day I dynoed 421 on a dynapack, the owner/operator at Car Version 2 told me that I could expect 440 on a dynojet.
