Those who plan on Supercharging, along with other Mods, need to keep that in mind when choosing the right gear ratio. If you go with a 4.88, you may hit the redline in 4th gear before the end of the 1/4 mile!! I would think that with a SC, trap speeds in the 1/4 should be in excess of 115mph? Add in headers/exhaust, VEC2, etc. and you may need the stock 4.11's to get through the 1/4 mile in 4th!
Can one of our Math Majors do some quick calculations as to what RPM we'll be turning in 4TH Gear at 100mph; 110mph; 120mph with 4.56's AND 4.88's???
(Hey GearHeadBill, wanna take your truck on a Banzai run up to these speeds and tell us what RPM's you're turning with the 5.13's??

)
I honestly don't know how 5th gear would work out on the strip??
Just thinking out loud again
