I have around 4-5000 miles on this setup and had a few set backs this summer that kept me from the dyno (4l80 swaps and oil leaks). I had the car running great but I decided to take it to Clint at AIR for some fine tuning. Super happy with the results.

 

Nice numbers! Was that with a t56 or 4l80? What intake manifold?

 

awesome ! i just got a comp 7879 , i kno diff turbos but those numbers look promising .. congrats ..

 

T56 and a LS6 intake.

 

Strong numbers. Do you plan on going to the track?

 

Stock cam, and only 10#! Nice numbers!

 

Nice numbers. How much boost? Hoping I can hit those numbers with my build.

 

That power curve looks great. Numbers are very impressive for 10psi! What cam are you using? Cant wait to get my 7875 build together!

 

seen 10#. how does the turbo spool?

 

Ray, I'll try and get the video up and running for you. Thanks again for your business, very nice car.

Clint

 

Put a cam in it and 20lbs. then youll see fast.

 

Very nice results Ray, glad you are enjoying it!

 

I am very impressed. That car is very street able

 

Maybe next spring.

Thanks! I have a Datsun 280 that I'm about to stick a 5.3 and powerglide in.

Stock 99 LS1 cam, 202/210 472/479 117 LSA.

Boost is on the bottom part of the dyno sheet. It makes full boost by about 2900-3000rpm on the street.

Thanks Clint!

Cool.

Thanks Jon! Clint shot some sick video footage, hopefully I can post it tomorrow.

Thanks Jesse, this thing drives super nice. And still spins at the top of 3rd

 

Very nice number for 10psi! I keep having little set backs myself with trying to get to the dyno. Im at about 15psi with my 7675. The Huron kits are def a nice piece

 

Nice numbers Ray! I am curious to see your trap speed at this boost level so I can see how much I would gain with the 7875 over my TC78. I trapped 129 at the end of this year around 10.5 psi.

 

Thanks Dave! I'm curious as well, Jon trapped 126 with a slipping trans on 11lbs.

 

x70189237401928347 nice numbers for the boost level! How much timing are you running? Any meth?

 

15* at peak torque, 16* at peak horse power. No meth.

 

read your build thread and 1999BLACK Z28 build thread. was hoping both you posted results. wanted to see some numbers between a tc78 and 7875.
