Default Lots of new mods coming, what should I expect....?

I'm ordering a 100 shot and S60 with 4.10's for my 2000 bolt-on M6 TA.

Current best is a 13.7 and 2.1 60'. We're over 5000DA here in Colorado

Question is, what is this going to do for the car? I can't seem to get a straight answer as to how 4.10's are going to do with N2O on a 275/35 18 DR. Am I going to run out of gear? Am I going to need taller tires? I've heard some say the 4.10's alone will give .5. Not that I believe any of this, but anyone with a setup like this? Looking at H/C later on too.

John

Wow, I would have thought a reply wouldn't have been quick with this one.

A few years ago, I had cam only (TR230) full bolt ons, 9" with 4.11's tnt 150 shot 26" et streets and ran 11.90 on motor and 10.82 on the 150 shot. The car dyno'd 390 rwhp.

The 275/35/18 tire does not have much side wall. I would get some salad shooters and some 26' tires just for the track or something.

Well, I understand it will be decent for a cammed car, but I don't think I'll cam it for another season or so.

I have BFG DR's, and they hook, I'm not worried about traction just yet.

My questions is, is there going to be any problems with getting down the 1/4 mile with the setup I'm looking at and being in a power band?

The RPM calculator isn't much help because it doesn't display distance.

Yes, you will run out of gear on a 275/35/18 DR. That is only a 25.5" tall tire, and it is not going to grow like a bias-ply slick on the big end.

Like Matt said you are going to run out of gear. I have 4.11's and on spray I crossing the traps at 7000 + rpm's. On motor they should be ok.
