Thanks man, DA is density alitude, measures the thickness of the air.
For a stick car that's probably around the sweet spot. Don't wanna launch too hard on a radial.
You can run more boost and timing with e85. I had 3.55s to begin with but I was running out of gear at the end of the quarter mile in 4th and didn't want to shift into 5th. 3.31 gears are much smoother then 3.55s and I felt I could launch the car better.
Thanks guys! I'm running a 305/45/17 et street r on a race star 17x9.5 in the rear and 17x7 in the front. 3.31 rear gears launhing between 5500 and 6000.
The mantic clutch is amazing, I've taking this car to the track many times and it hasn't given me an issue. It is a ceramitallic twin disk...
