just curious here.. i couldnt get better than a 14.1 at 104mph with 2.3 60' yet i have done a couple 2.2s in there.. riding with a 2.9zzp #42 and drop in K&N.. can i be in 13s?

it feels like the powers there but im losing a lot maybe in first

thanks fellas

 

your trap speed says alot... yes i belive you can get those 13's if you get those 60's down

 

The standard rule of thumb is that for every 1/10 you shave off your 60ft. time, you net twice that much of of your 1/4 mile ET.

So if you ran a 2.3/14.1, then a 2.2 should have netted you a 13.9 ET.

 

Maybe. I've got those parts (2.9 +#42's.) but I also have alot of other stuff. FULL exhaust, AEM CAI, ported blower (modestly), NGK plugs, SSC springs, Dyno tuning (limited boost in 1st [8psi]) and my best time so far was 13.6 @ 106 on a 2.3 60'.....
i think what you need to do is go get your boost limited in first gear. then maybe a 13.9 is possible you next mod list definitly needs to have a header, downpipe and maybe a torque damper.. then you'll be around 13.7-13.8. your stock exhaust is restricting you alot at this point.


for comparison:
best time before exhaust and ported blower.. 13.8 @105
since exhaust and porting: 13.6 @ 106

best 60' to date 2.2 (stock on a 14.7 @ 97 run.)

best modded 60' 2.3 on my many 13.8 + 13.9 runs

anyway, i hope i helped a little

nice trap speed. it shows you've got the power, but limit your boost to like 8-10 psi in first and you'll be ok at the track. (i dont spin or hop.. thats why i don't waste money on traction mods.. not yet anyway)

 

i was able to run 13.9@102MPH with a 2.1 60ft. I have pretty much the same mods as you, so i think you can do it with some work on your launches and shifts

 

don't be mad traction in these cars blow you will do better limit boost in first or get really good at launching

 

thanks i appreciate the feedback. i have a custom hp tune my buddy set up for me (WickedSS) im really not sure what the boost levels he set in 1st were, im actually launching pretty easy on it, just even to get rolling then stomping on it and not getting any wheel hop. its pissing me off though, illl nail my start and then ill f' up missing 3rd and ill run a 14.3..

so moreless ill get my boost limits checked out in 1st.. i think im pretty good at launching the cobalt.. and im really thinking about getting my blower ported and a manifold/downpipe

 

missing third really slows you down

 

also, keep in mind, that altitude, temperature, track conditions, track prep, all have big influences on times.
dont be disheartened if your mods dont seem to line up with what other guys are running.

 

yea i keep thinking i should be running 13.8's.. i wanna see a 13 so bad to join the club. ill keep at it and hopefully itll come

 

I was able to hit a 13.80 at 105 with the stock exhuast system on s2 and 2.8 so you will
deffintely be able too.

 

I ran 14.1 @ 107.... with a 2.58 60'

 

13.5 @ 105 with 2.9 and 42's. just get better at that launch dude.
