Today I just finished up tuning a 6-speed F-body we built with our single turbo system (using TTI race hot parts).

370ci iron block, out of the box AFR 225's, 225/225 113lsa cam, Innovative GT76 turbo with 1.15 R-trim hot side.

Boost was 19psi at peak torque, 18psi at peak horsepower. C16 fuel, 21 deg timing @peak torque 23 deg timing @peak horsepower.

Engine management is BS3, used in conjunction with our plug and play piggyback harness which allows the stock pcm to run the gauges, and if so desired, fans, fuel pump, reverse lockout.

Wow, crazy high numbers.

 

damn that thing sounds like a beast what do you think in would run in the 1/4

 

Impressive as always sir.

 

Nice! You have a lean spot at 4k rpm though...you may want to look at that.

 

Any pictures of the car. Street car?

 

Thanks for the tip. Air fuel on the BS3 showed 11.9-12.0 throughout the entire run.

Here is a plug from that pull.

So is the BS3 wrong or the dyno's WB??? I cant tell form the plug the difference between 12.0 and 13.0....Either way, I am sure you know what you are doing, just thought I'd point it out.

The BS3 is correct. I have many dynoruns showing the dynos wideband matching the BS3, this run may have been an anomoly, or the filter in the wideband needs to be changed. (I have not yet checked it.)

 

Nice and smooth curve! Impressive.

 

Very impressive numbers, but I'd say that the heads need some work.
