Are you losing boost after 7000 rpm? The torque shouldn't drop off like that unless the boost is dropping, you have a really small turbo, or something is leaking/wrong.

at that boost level on that kind of manifold with that kind of gas i would think 500whp. I mean 120mph is at least 400-425whp which is still great but seems like it should be more.

 

Doesn't matter what the horsepower reads as his trap speed speaks for itself. Not a great trap speed considering its race gas, but its still not what 350whp would do on higher reading dynos.

 

Thats why i was thinking 400-425 range. Santaur has a fullrace 30R with 425whp i think from that i remember. he was trapping around 122mph so its around there.

 

yeap
I'm running GT3071R .82 AR and 630cc injectors.

We did the dyno run with hood closed. Also tried hood open and gained about 25whp. my air filter is sitting at really hot area.


I really don't care about the "NUMBER" because my trap speed tells everything.

 

AMEN,

When are people in the import world going to come around? Dyno's are very different and give all kinds of crazy numbers. Power should be based on trap speed.
I wish this forum would come online and do the same by posting trap speed instead of hp.....if you know it. If you don't that it fine.

You should also look into blocking out your license plate in the second pic. It shows up clearly.

Nice car BTW.

 

20 psi race gas, there has to be something wrong only making that much power

 

Why does the torque drop like that.
A GT3071 shouldnt fall on its face like that if its boost.
Good trap though.

 

Dragtimes horsepower calculate's 365 crank power for a 2900 pound car
to do an 11.9/120.
What do you think?
