Gee I was begining to think nobody would try it,
Don't know how long I have advocated this, as the best and safest mod.
A 17.8% difference in gearing will reduce the load on the gearbox, and give the same percentage increase in torque at the wheels.
If the 3.545:1 does 15.5 for the quarter, the 4.11:1 should run about 14.8 secs. Add a nox boost to that and it's headed for high 13s
