You're clueless! :lol::lol::lol:
One thing I know for sure is that above 160mph, a fullbolt-on 475rwhp BMW M6 won't pull away from stock Ford GT. And guess what, a Ford GT's 4th gear ratio is .94:1. A Ford GT is a top end MONSTER.
1st - 2.61
2nd - 1.71
3rd - 1.23
4th - .94
5th - .77
6th - .63
Final drive - 3.36
Your theory of a 1:1 4th would make a C6 ZR1 weaksauce too right, NOT!
1st -2.29:1
2nd -1.61:1
3rd - 1.21:1
4th - 1:1
5th - 0.81:1
6th -0.67:1
Final Drive 3.42:1
you guys alll forgot the most important factor! WEIGHT!!!
between the Z06 and the M6 there is about an 800lb difference!
