I am pretty much sold on the twin screw design for the wide torque band. This vehicle will be a daily driver / project car for me. I believe the LS3 Camaro comes stock with a 3.45 gear ratio. That's pretty tall, when compared to the mustang drag pack that comes with 4.10 gears.

I have been considering either 3.73 or 3.9 for increased quickness off the line. I can't help but feel for the horsepower advantage, the camaro should have a wider margin over the mustang. The questions I have are:

1. I realize highers gear ratios = higher engine rpm.

A)Will higher gears help acceleration or will they just result in traction issues?
B) Are they feasible in conjunction with a supercharger or will the higher rpm limit total boost?
C)Will a gear change force a reflash of the computer, and how does this affect the traction and stability control?

I know kenne bell is adamant about not using other upgrades in conjunction with their systems. I know these are a lot of questions. If a member has done this with previous vehicles I would appreciate your advice. If you guys know where I can read up on this please post a link.

So far most of what I've read are on vendor's websites. Thanks for your time.

This is really something you are going to have to talk with the people putting in your super charger about. Depends on how much hp/weight, tire surface area, and all kinds of stuff to determine the appropriate gearing.

I personally believe anything above 3.73 for this car stock is going to be to much. Probably be hard to get off the line without shredding your tires if it was anymore, not to mention gas millage.

Your in luck right now though because as of now no one even makes gears for the camaro.
