well not enough info here, but first what was your MPH stock? ET = traction and your 60' wasnt very good. also, you were spinning which means less track to actually run which means slow mph and et. get some traction, make sure your shift points were on mark, and practice practice practice. nitrous doesnt make for ET, traction does.

Brandon, what rpm are you spraying at and until? Do you have a window switch? What pills if you have 1?
Driving a stick is not that easy with nitrous-things start happening real fast .
You might just need to learn to adjust your driving and practice-practice-practice.

What do you run for time and mph on the motor?
List your entire time slip for better help.

What do you run without nitrous.
Those numbers look fine for a M6 without spray. Just curious,but are you sure the nitrous kit IS working? Not trying to be a dick,but are you sure it works?

I have seen many stock LS1 sticks run that mph and time.
I have an automatic and run 8.1 @ 87 in the 1/8th.(all motor)
Did you double check the FPSS is working (if there is 1)?

INHO, it looks like since the nitrous doesnt come on till 3000 rpms (now i am fully guessing, but listen up and see if i am off base) you launched on radials nice and smooth, got a decent 60' then probably around the 80-90 foot mark, went WOT, the nitrous kicked in, and you spun all the way down the track = crappy ET and crappy mph since you were running on like 2/3s of a track at wot.

but hey, this is all a guess, but i have seen it tons and tons of times. also, i bet a rev limitor a two occured = loss of mph and ET. OR you short shifted = loss of ET or mph. finally, since this is a 100 dry shot, it will make around 80 rwhp and noticed about a 7.8-8 mph difference which is right on where it should be with that power. finally, how do you know you spray between 3-6K rpms without a window switch?

When i start i ride the clutch at 4000 rpm and then it bogs down a little. After the launch i hit the button which is around 3000 rpm. Also i shift at 6000 rpm. But when i run i am not spinning the tires threw first gear. I think i need gears personally.

Dont feel so bad. My car's best E.T. Stock was 14.0. I also went low 13's on 100 shot and 12.70's with a 150 shot. I thought I had a lemon. But, I practiced and practiced and it just kept getting faster. My car also responded REAL WELL to Bolt ons.

Slicks, Tuning, Cutouts, Headers, Gears, Lid, 3000 stall, 12 Bolt= 12.70

MTI Head/Cam/TP4400= 11.60@116 and 11.0 on Nitro.

With just bolt ons you should be in the mid 12's. First thing I would do is get some slicks.

BTW: My times stock on spray, I was spraying out of the hole.

gears will NOT help you bro. it will only make you spin more. take some of the advice here on this board and practice.

What bottle pressure were you running? The difference between 800 psi and 1050 psi will make a noticable difference.

I am totally with Doc and Gator. Bottle pressure and practice are key to a successful M6 pass. When I had my M6 it was so hit and miss on my passes. At one time (car still pretty stock) I was running a 125 dry shot on street radials and was hitting 115 mph, and only running 12.99's. It was maddening!!
I also learned that bottle pressure was as important as what kind of tires you run. If my bottle is nice and toasty (1050-1100 psi) it is night and day compared to 750-800 psi. At those lower pressures, you might as well not even run the nitrous....you just go pig rich, and the car runs like crap.

Get it up to at least 1050 psi, get some tires, and practice. Then you will see the gains your looking for.

I first got into the 12's by accidentaly breaking the nitrous arming switch in the on position, so I tried it, right out of the hole with the juice allready armed, you'll be doing much better, although clutch and rear end will go soon!

Yeah it is. Below 3K RPM can break alot of parts.
