and if you guys must know heres the specs of my cam 207/220 .571 .578 118.5 ICL--its a LPE GT2-3 yes very small I know, but I daily drive my car everyday and traffic gets pretty heavy around here so I won't get a bigger cam untill I get another vehicle.

I wasn't powershifting and I don't believe he was either, but even my granny shift is pretty damn fast.

yea you got the jump mainly because my TCS kicked in right when I hit it and it cut my throttle a little bit, i figured this would be better than to risk having my *** end slide into you-and no i didnt powershift.

M6: 80mph should be around 2150rpm with 4.10's

Nice close race btw.

Sorry to inform you but your gears didn't help you as much as you think. Gears only help you off the line and marginally at rolls starting at <25, after that its just different shifting points, no added accelereation. 35 is the worst possible place for a m6 with stock gears. Race from 45 and it should be a different race.

Go to gear calculations on here under gears and axles and check your rpms. That will get you somewhere close. I have 4.10's in a m6 and I am around 1900 at 70 mph. You should be a bit higher.

Nothing to be ashamed of in that run. What the video doesnt show is that the TA was out by a car at the end. TA out horsepowered the SS regardless of gears or driver or whatever.

What do you guys expect 10 car lengths? Forgot about the ricer calculator conversion: 50whp = 2.5 car lengths.

The street is a dirty, filthy animal.

BTW, that particular TA can keep up with a 400+whp GTO.

1 minute before climbing on the dyno I added the MTi Lid....

Since the dyno I did the free ram air mod and added a Hypertech 160 t-stat...

I did not reset the ECU before climbing on the dyno and from what I've read that would possibly indicate that the lid had little/no affect on my dyno run...

I checked it on my long drive after work yesterday...

I was at exactly 2000 rpm at 80 mph per my stock tach...

My speedometer has been adjusted with the Superchips Programmer to compensate for the gears...

Yeah, you've got nothing to be ashamed of Nick....

It was a fun close run, and, as I already stated, if we had kept going beyond my 4th gear it would have been murder....





I dispute the idea that gears make no difference above 25mph as others have mentioned....1st through 4th gear it makes a noticeable difference IMO, and while my shift points do come up sooner than a stock geared M6, I am capable of shifting fast enough for it to not make a huge difference....

Apparently we need to find 2 stock M6 cars, 1 with 4.10s and one with the stock 3.42's to see what the true difference is..........but then everyone would start arguing about drivers.

I spun a little, but not enough to bring the car sideways or anything else...

I've got no TCS on mine for those that are wondering...

The 345whp/360wtq is a guesstimate based off a dyno run that was made earlier this year...

http://www.youtube.com/watch?v=6cRS2LNrbHY


When the dyno run was made my car had RandomTech cats that had been gutted, a RandomTech y-pipe, a Hooker Street Force catback, and the Superchips tune all running through the 4.10 gears...

Right before the car climbed on the dyno I added the MTi lid, but I did not reset the ECU and from what I've read that would indicate that the lid had little/no affect on my dyno run....

The car put down 334whp/350wtq as can be seen on the above sheet and in the video link above....

Since then I've added a Hypertech 160 t-stat, adjusted the fans to compensate, and completed the "free" ram air mod....

Taking into consideration that the lid probably had no affect on the dyno and the topend power freed up by the "free" ram air mod I guesstimate the car is now putting down 345whp/360wtq....




Ask yourself this, is it better for me to have 345whp/360wtq, or is it better for me to have less power than I claim and to have kept up as well as I did against the 395whp Trans Am

Honestly the only reason you guys were so close is you made him start at the worst spot for his car and your gears helped out right there. By the time I heard a shift he was pulling.

Well he obviously wasn't in too bad of a spot if his TCS kicked on

My stock GTO can spin the tires over in 2nd at 35 mph, sometimes 3rd.

Honestly gears will give you about 2-3 tenths.
