3.15's MT82 Paxton

[TexasGT]

No way I can do a 40 roll without drag radials. Someday we will make that happen! Gotta keep good street tires for upcoming Texas Mile.

My 20" nitto invos won't hold from 40 nor Lund's 2-3 shift. My recent run vs a 383 4gen camaro was pretty scary.

I can't even 60 roll in 3rd without DR's on the 3.73. lol.

Then start from a 40 roll. Gears don't make a ton of difference when your roll racing.

A 40 roll? That's smoke city. My car even spun a set of warmed up NT01's bad enough to abort a run.

Sounds like you guys need drag radials or a more ginger left foot to me. Maybe both.

Definitely DR's. Third gear spins for me at 75-80 even doing a roll from low rpm, like for a datalog pull. When you're around 700whp, you need DR's for sure.

Clearly you didn't read the part where I'm running a tire. I also have a second set of wheels running MT ET Street Radials.

I have enough seat time to know how to drive a car through some wheel spin. This isn't the case, the gears are too much.

Maybe on some 400-650 HP car it would be a great idea to share these ideas, I'm well beyond that and am looking at gearing for specific reasons (outline quite well here I think).

For folks doing this swap, are you taking the pinion flange from your original housing and putting it on your 3.15 unit? Haven't had any luck finding the part number for the manual trans flange.

a stickey tire is a must...... that is the first thing to do to help with traction, the 305/45/17 street r's are a great tire and what we usually recommend for the gusy

Any recommendations on a wheel for that size? Would a 17x10 sn95 replica wheel work?

Any 17x9.5 10 10.5 11 would work.

As for pinion flanges, I've reused my stock one when swapping differentials. Just have to ensure it's torqued properly.


The biggest reason behind a gear swap is trying to stay out of 5th. A 6060 swap would work but I'm likely going with Calimer's G-Force MT82 when it's ready. Hence the gear discussion.
