I used the transmission trick on this car and well it helped it alot. Keep in mind this setup is best suited for tracks with really long ass straits. And for those that are into 1/4 mile times this car will run a 9.985 without the use of nitrous.
I only thought it would be nice for some tracks with lond straits because of the strait line acceleration would get you away from the other cars. I haven't tested the supercharger yet on this car yet how does it perform with it (stock gearing and such). Also sorry if it took so long to reply back. My damn comp caught a virus and I went out and just got a new one.
