Assuming a great launch with no spinning in either setup, I don't see the 60 foots being that much different because that is where we already have traction problems, regardless of being turbo or not. Once we hit around 20-30mph is where I can see the turbo finally start to pull past an N/A car....and it'll probably do so real quick.
I can see it being harder to launch the turbo with precision due to the throttle being that much more sensitive to foot movement. Regardless of how much HP you add, the distance the pedal has from the floor is constant...therefore the rate of change is MUCH greater thus increasing sensitivity.

Yah, kind of what Hexx was saying. I assume they will compete similar for the first 100 feet or so. . .but after that it would be neat seeing the difference side by side and how much harder the car pulls. Does that make sense?

Yes GXPJAY, How did it go? We need some real numbers of this system like MPH and maybe ET if you tell what the 60' is, and we want pictures/videos of everything. The suspense is killing me.

4. transfer video to computerthen internet.
5. share win with us.
