TwinTurbo '94 LS1Truck
Getting it moving, posted this on another forum, but thought i'd post up over here.
After a long time of waiting, putting it to the side, etc etc, it's finally going somewhere.
Turbos are pushing about 16psi thru the engine, 10psi launch, 105unleaded race fuel, still needs more tuning (hpt box is off getting repaired).
Here you go:
9.64 @ 140mph

I was going to say it looked like he was having a few issues at the shootout this year. Working on launching I believe.
Nice runs Allen. How much more are you expecting out of that set up? It moves for sure.

well that run was : 10-11psi launch, 16psi down the track, 105unleaded, 10.5 af/ratio, 17degs timing.
engine is at 8.2 to 8.5 cr and 16psi, so the engine isn't in it's efficiency range, it needs more like 20-22psi.
I had it at 22psi on the street, lol, too much and I ran out of injector (120lb injectors low imp and a1000), so 19psi might be max for now.
In the end, i'd like to an 8.80.

An 8.80 would be very impressive.
