austrian type-R

IMO it would be the best, when I rev near redline in 4th gear at the end of the quater mile, to get the best numbers, correct? It would suck when I have to shift into 5th and it would be not so good to drive throu the finish at 7000rpm. I have calculated my tranny with some different tire diameters and redlines. Now I need to know how high the top speed of a 350whp turbo ITR is about. Thanks!

is it possible to fit an ls(4.27)final drive into itr(4.40)???

I donīt see any benefits from doing this, cause the 3rd gear runs out with that final drive at 146 kph @8600rpm with 560mm diameter tires. I think Iīm doing about 180kph with 350whp, but I donīt know exactly. I have no Drag experience with slicks and that much whp.

Any more infos and help would be nice.

i think its better to play in the final drive for having the lowest slicks=more whp
lighter wheel = less energie
or correct me
