What gears for 135 mph+???? I ran 132.5 yesterday, with 6 speed, 3:73's and 27" tall tires. I went threw the traps, and as soon as i did my shift light came on at 6,200 rpm.
This means next year my car will be out of gear by 1000", what do you think, should i go to 3:55's? or what?
Thanks.

With 4.56 gears 5th would be topping out at 148
With 4.30 gears 5th would be topping out at 156
With 3.73 gears 4th tops out at 134
with 3.55 gears 4th would top out at 140
with 3.42 gears 4th would top out at 146
Hope something here helps!
If you PM me, I can send you a link to an acceleration simulator that will tell you what 1/4 mile times you will be running with each gearing setup, as long as you have a dyno curve to look at for each point on the torque curve.

Yeah, more RPM capability (I mean, 6200 is REALLY conservative even for a stock bottom end) and/or taller tires would keep you from having to change your gearing...plus, you'll likely be faster.
