Both my Fs have been pretty much the same speed. The main difference is the way you have to launch the car.

Sure. So the ultimate goal while racing is to put the most power down to the ground for as long as you can.

The reason that people believe that the E-Diff ISFs are faster is that they get out of 1st gear quicker due to the fact that they have less traction. The E-Diff ISFs tend to spin just enough to get out of 1st gear really quickly, thus utilizing more power for a longer period of time.

Though my 2012 car has "too" much traction between 2k-4k rpm, it can handle more load from a stand still. Knowing this, I combat the 2k-4k bog by taking the pre-load to the max.

If you look at most of the high hp cars, non of them dead hook. Dead hooking would most likely pull the car back out of the power band. Instead, they spin just enough to keep the motor happy while propelling the car forward. This video has a good example.

so your using using both feet and revving to roughly what rpm? I tried this method and it seemed to hurt my 60' but i may not have gone high enough in the rpm range

Yup, using both feet and bring the rpm up, but I try to modulate smoothly so that I launch as soon as I reach my desired rpm. I dont remember the rpm off hand, but ill launch the car tomorrow and let you know.

Couldn't help but remember this video, caused by using both feet in a launch.

Here is the ISF versus the new C7--a real world example of how the ISF can easily hold its own against US muscle.

HAHA that's my F running against the C7. Those runs sure caused a lot in internet chatter. The F can certainly hold it's own even with an E-Diff! I'm pretty happy with the car as it's never let me down be it on the drag strip or the HPDE track sessions.

Here is the in car footage.

Very cool. Nice job. What do you run with street tires. 12.2/12.3?
