Def get a tune ASAP, especially with that cam. Hook a sub 2xx 60 and you'll see high 12's, although a 2.08 is respectable for a M6

your main priority now to get that time down are gears and some tires

You ought to be in the 12's no problem now that you had a tune. Just make sure you are shifting very quick and at the right rpm's. Your stock time is quite slow and it may be indicative of not shifting the car in the most efficient way. I basically power shift
3rd and 4th, for 2nd I only power shift if I have drag radials, often times without drag radials she will break loose in 2nd.

power shift every gear but 60 foot was 2.30 when i was stock going to track this friday night hope to see 12s with 375rwhp with drag radials won't the rear break

did you run it with the tune yet

**johndob** · 06-20-2006, 04:44 PM

no not yet this friday night

Since you have gotten your tune my guess is, with that horsepower, that you will run mid to high 12's at over 112mph. I'm sure you'll have fun doing steering wheel corrections on it outta the whole. That's alot of power.

I think you'll do just what Bob said above. You ought to run some great times as long as you can get a good launch. With drag radials and that kind of power you may just break the tires loose way too easy by power shifting. But if you still have a stock clutch you may indeed run better times than with an upgraded one only because the stock one will slip when the tires adhere and actually give you a good time overall up to a point that is. Of course don't expect a stock clutch to last too long, mine didn't with some hard launches. I made the mistake of getting a clutch that was way too good for the stock power I was putting out back in the day and it actually hurt my ET's because it wouldn't slip, it would catch like a raped ape and make my drag radials break loose very easily.
