Tremec magnum xl vs Mt-82 gear ratio comparison......

Yes, with a Tremec i would have no hesitation for a 4.10 gear in back.

God damn that boss moved out on that zr1

What about the magnum with the 2.66 ratio

Lower is better.

Very close for sure. Depending on model year and options, a Z06 isn't going to be 3200lbs, more like 31xx or 3xxx.

My 2008 base model vette(steel frame) with drag pack and passenger seat removed was 3029lbs and went 10.67@129 all motor. Weight matters. lol

So since a premium is closer to 3600 and the 550 whp I was asking about is probably a tad higher than 600 crank I'd be fairly close un my guess that that would be pretty similar in how hard the are able to pull and overcome the gear?

I have an n/a cobrajet setup, cams are soon, and eventually plan to spray a 100 shot. I already have a tremec XL with 3.31's on my 2012, its a disaster, the car had a vortech in the past which made the ratio's work specially when roll racing. For an N/A setup im thinking 4.3 or 4.56 will be needed to trap properly. I also use the car for road course on a different suspension setup (the primary use) I think 4.3 would be ideal but also means alot of heat in the rear end.

Suggestions ?

I have a T56 2.97 with 3.31 making 675/590 TVS, E85, with 305/35/19 ET Street SS and to me it hauls ass. Sometimes I think about going with a 3.55 but worry about traction since the whick will be turned up when the motor is built. Would be really cool if there was someone local with a similar build but different gearing.
