So far i have gm stage 2, k and n drop in filter and vibrant 3" exhaust. Right now im running 14.4 1/4 mile times. Yeah pretty slow, im not the best driver i have only been out to the track 3 times in my cobalt. If i put on a zzp dual pass plate is it safe to run a 2.9 pully with my set up? And can someone PLEASE explain to me what the option "b" is!? Thank you.

 

You should be able to run a 13.9 right now. Go out and practice driving.

 

yea you should run better than me im running 14.6 with everything stock havent had anything added to the car but a new clutch lol

 

Thats what i was thinking! lol. but i dont have the limited slip for it is a 2005. think im loseing power with my vibrant 3" exhaust? haha. and my trap time was only 99.6 mph.

 

^^^^^TRUE!^^^^^ Practice your launch the most!! dont dump the clutch ever you will just spin w/out slicks. lower your tire pressure to about 18lbs or so at the track and do a burnout not in the water box not needed on streer tires. Go off the tree like a normal stop light ease on the gas in first then floor it once you hit second you should be golden. Also relax have fun out there dont overly excited its you and the clock!

 

i was under the impression that it is not safe to burn out in our cars due to wheel hop...?

 

i dont have the limited slip either lol and its possible to do a burn out with out wheel hoping i done it just have to rev high to make sure those wheels break loose and stay loose for a short time lol

 

Sounds to me its alittle off but not by much, most stage 2 cars run low 14's@100 or so......

 

so are any of the people on these forums running a 2.9 pully with stage 2?

 

There are many, including me. I have not had any issues with the 2.9 on GM stage 2

 

ya me and bl4des b4 he got tune the 2.9 SUCKS on a stg2 tune DO NOT TAKE IT TO THE TRACK the 2.9 is faster at first but the original 77.9 (or w.e original stg2 pulley is) cuz its faster in the long run other ppl may disagree but we did a full pepsi challange and that was our conclusion

if u do shift at like 6 grand or yull already be out of your power band

 

If you wanna trade your exhaust for a 2.5 inch i have a corsa touring. ill pay shipping both ways, lol.

 

lol i would but i love how loud my exhaust is. I think i just need more mods to use its full potential. haha. Is this true about the 2.9 pully? could it of been that you were having heat soak without cooling modifications?

 

Like stated above just keep practicing and you will get it. I am Gm stage 2 with intake and ran 14.06@102 I still feel like there is more in it too

 

tires.

 

tires and practice. youll get it just dont get discouraged. these things are a bitch to get off the line

 

LSD wont make that big of a diff. I have an 05 without lsd and ran a 14.2@99mph with a 2.3 60' time.
We have a guy here in florida ran a 13.0 @108 on gm stg 2 tune and a 2.9

 

LSD wont matter much on the strip its for cornering boys

 

LSD doesn't always mean POSI

 

How would a lsd not help? Soon as one tire spins faster then the other it sends power to the slower tire. It dosent matter if ur going straight or turning.

 

maybe his track is a t a bit higher altitude also, have to remember to factor that into his times

 

i have the same exact set up. i drilled out the cat though. that would be our only difference. i ran a 14 flat rolling off the light like a traffic light and never put it to the floor till about 5k in second gear. did i mention i beat a 09 LNF with exhast by .30?? he was pissed

 

i was at the track last night with just the stg 2 and ran a 13.9 it can be done

 

Nope, an open diff will spin wheels at exactly the same speed going straight.

The only way you're spinning one is if you have some serious mechanical problems or your track blows.

 

that is what is i ran the last time i took my ss to the track all stock.

LSD would help alot... helps you hook up.
