I tried to spray the Z last weekend and could not get the MT 275/50/15s to hold the spray coming in right at the 60ft. mark. The tires held decent on one pass but the nitrous was to much and caused the tires to spin all the way through most of 2nd gear then finally hook. I was playing with a 100 shot and i would like to spray a full pass on a 150 shot but if the tires aren't holding a small shot then im wasteing time.

I'm thinking about the 325/50/15s for my 10 inch pro stars. The setup is a TCI 4000 stall,9 inch with a locker and 3.70 gears. The car runs 10.90s NA in decent air and hooks mid 1.4s on motor alone. Will the 325s kill my NA setup? I may bump the gear up if needed but i would like to know what you have seen from this swap.

For one there is a 6 pound per tire difference, which will slow the car slightly, and the taller tire would slow the car.

The 325 being bigger will give you more of a cushion on the traction factor.

Geared accordingly I doubt you would lose much ET on the motor and with traction problems on the n20 it can only help.

I think a 325 50 15 swap is an easy fix unless you want to keep the same tire and do a lot of chassis tuning to get it to work.

you could go to the 275/60 which is the same width but 28 tall, that would probably help some with the traction, and they have got to be lighter then the 325. If possible can you get rid of the delay with the nitrous and have ti come on right off the line? If so try that, the tires like to be hit hard. Sounds like what is happening is the car leaves, then the nose settles and the nitrous hits at about that time, as the weight is being transferred back off the rear tires causing the spinning issue. If you can get the nitrous to come in right away, it will certainly 60 foot a ton better and then it won't be coming on as the car settles back down, so the spinnign 60 feet out or so shouldn't be as big an issue. Car might want to come up some though, so be ready just in case.

I hope that makes sense.

My Camaro went 11.02@121.6 on a 1.55 at the LSX Shootout, that's with a tight converter, 4.10's, and 28x10.5 slicks. It's gone 10.1@133 1.45 on nitrous, middle of the summer, that would be like an 9.85 would be my guess (went 11.3 na that day too). I think you will lose a solid tenth on motor and one mph but then you can hook the nitrous. I'm probably going to put DR's on the Camaro too I get tired of airing up slicks all the time.

That sounds like a plan! If the track will stay open a little longer i may try it one more time with the 26s before i change to some 28s for next year.

If you can get it out again, mine as well. Get the thing to hit all at once and the 26 might take ya farther then you think, only way to find out is to try it.
