Default Turbonetics 7875 Dyno Results

My setup:

129k LS1 stock short block
Huron Speed kit
Turbonetics 7875 .96 a/r
317 heads
1218 pac springs
Pro comp head studs
LS9 head gaskets
Stock cam
Brain Tooley lifters
7.375 PR's
60lb Siemens
Racetronix fuel setup
91 octane
Full 3" exhaust to a Hooker Maxflow muffler

First pull had wheel spin



Second pull



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.

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

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.
