My car did seem to fall on its face the First 10 Feet or So. Then everything went well. Othern then that I Can RUN a 13 Flat With out the shot of Nitrous
picking up on 3Tenths? sound OK? I feel it should have done a Tad Better

dude, those 18's are killing you. you need 15/16 MT's and with any decent 60 ft. you'll be low 12's

Your 60 foot kiled you. This is indicative by not only the 2.1, but also your MPH. Could you maybe elaborate on the first 10 feet?

It felt Like the Car Just BOGGED out. Reason??? I am Unsure of Maybe To Much Traction I was thinking the Track was Hooking up well and I was only Running 22 PSI.That or maybe a Stall is needed?

too much traction? my friend, a 2.1 60ft is nothing of the sort. If anything something is a miss.

I would guess that it's a combination of stock torque convertor, 2.73 gears, and those 18's. It takes alot to get it moving with all of that holding you back

Thats WHat I Thought,,, The N/A run I pulled a 13 Flat .. However I was on 245/55/16 Using a Nitto Tire. These New Wheels I am thinking are Making a BIg Hurting.. I could be Wrong tho

60' is the killer. lose the 18's for 16's with a good set of DR's. If you can drop 4tenths in the 60' you'll be in the 12.3-12.4 range

You said too much traction so you are not spinning?

Then you are waiting too long to turn the N20 on, IMO you need to stall it up as far as it will go roll out a few feet and flip the switch just make sure you are at wot. If you dont want to do this then you need a stall.

I run 18" Bfgs and run 1.70-1.73 60's with a stock stall and taller gears, but in a C6.

I have seen 18" nittos and bfgs run 1.5-1.6s I think it is lack of power...

If you have a window switch keep lowering the window 200rpm till you get a good 60 or spin too much.

numbers look like they are right on with a setup that doesn't spray until about 60mph down the track. so no....you are not getting any traction. with a 2.1 60' and if you're spraying off of the line, then it seems to me like the nittos are doing their job but the nitrous is defeating the nittos gain because you're 60' is normal stock time.
one more...if you only picked up .3 then something is wrong. but i'm leaning towards the spray hurting your traction early because a 13.0 with 311hp NA should have a 1.7-1.9 60'.

SY732

So tell us your full setup and what hapened

Z2K_MrJ

My SPray Kicks in at 3k RPM in 1st Gear which is way before 60 PMH.. SO No Spray off the LINE. I think it was a COMBONATION of Low Tire Pressure On a 275/35/18 And a Sticky Track With a A4 ...Ill go back again soon and keep Pressure at 35. And see if this makes a difference

get rid of that tiny gear and get a stall with some mt et streets and then you will see low 12s maybe even very high 11s . I think that gear with the stock stall is killing your 60 times.

I'm not sure why everyone keeps saying wheels. He never mentioned having any problems with traction. His 60's are shitty cause he's bogging out the motor on the launch, not cause he is spinning. Like some other people mentioned, stall and gears will get you off the line without bogging down the motor. If you still end up with a 2.1, then you may want to upgrade to 15's with M/T ET streets. Was this at Englishtown or Atco?

Falls on it's face for 10 feet? You didn't by any chance leave the traction control on, did you? That would account for that.

Get rid of the 2.73s for some 3.42s, get some 15" or 16" wheels with Mickey Thompsons, turn off your traction control, do a strong burnout and then hit the nitrous off the line. Hello 11's at 116+ and a 1.6 60'.

...change the gears or change the stall. Maybe even do both. But do not pick up that tire pressure to 35psi unless you want to see the wall!! And you have the rpm range right, so dont turn on the spray before 3,000rpm's. your problem could be that you have too much tire for next to nothing mods, try not doing a long burnout and do a quick 3-5 second burnout at 22psi. You can even bump up your shot to a 100 shot and it would be safe. Stall up the car as high as you can, which probly aint much since its stock, and see what that does. Keep us posted.

SY732

If it did not spin then you are waiting to long to spray, stall it up as high as possible, and lower the the window 200 rpm at a time till you get the result you want, 3,000 is the safe norm but many say 2500 or 2000 with an auto read up and make your own choice. Or get a 3800 stall.

IMO you will need to get it too 1800-2200 to see a gain in the 60'

I think that if he's already having somewhat of a bog issue, telling him to lower his window switch. Actually it would probably cause a backfire. Could you maybe post up some of these instances when someone says to spray at 2000 for an auto?

SY732

Use the search there are many posts and at least one huge thread would you spray below 3,000 or somthing like that.

I dont see why you think it would backfire but if the tune is off I would not spray the car at all.

I have seen guys spray at WOT off idle ~1,000rpms many times, now I would not do this but it works 1.5 60's with a stock stall and 2.73's gears.
