fwd cobalt stocker

efi v6 · 12-19-2010, 09:37 PM

I am thinking of building a 2008 cobalt 2.2 auto. for stock classes. Does anybody on this fourm run one? I ran the car in all oem trim best et 16.30@ 84.20 with k&n filter in stock air filter housing and some tuning ( by myself ) with hp tuner software went 15.89 @ 86.87 ! Ran out of testing time as the tracks in the northeast are all closed for winter. What do you guys think.

Well it's a Natural D/FS with an index of 15.60 needs to weigh 2830 with you in the car so??? Ya might just get their. you "could " add weight to make it an E/FS but would need to weigh 3670 with you in it! 17.65 index though

1320 / MPH = optimum ET.
Using your numbers, if you had slicks / suspension / convertor sorted out for drag racing (not street / strip) and without lifting the hood, you should be capable of running 15.20's or .400 under the index. Keep in mind slicks may be a lower profile than your street tires (you still are on street tires, right?) which will not only aide in traction but will give you a lower gear ratio. That right there could get you in the 14's.
This is the exact path I had with my street '87 Dodge Dayton Shelby Z (2.2L inter-cooled turbo). It had a MP computer and a cat-back. It ran 15.40's with Radial T/A street tires and poor traction. I was already about .400 under. I added slicks and tuned the waste gate and boost, an open exhaust and air filter, advanced timing, race gas and Koni shocks with M/T slicks was good enough tho set the B/FS record @ 14.17 without ever having the valve cover off the 75,000 mile engine.
I then rebuilt & blueprinted the engine with gapless rings and refined the a/f mixture and set the A/FS record at 13.26.
I say you go for it and I hope you can dedicate your energy into it for a lot of fun. Ideally it's not your driver (like mine was).
Good luck!

My son had a 4dr model. We did absolutely nothing to it and it ran within1/2 seccond of the index. We were gonna tinker with it until he decided his front bumper looked better on the back of a mini-van.
It will work

My wife had one a few years ago as well, and it ran similar to Chip's kid's. Ran it across the scales, and it was over 3000#. I've called this one out as a sleeper Stock combination a couple of times! Git 'er done.

Thanks for all the help and support gentlemen. Jeff , yes that was on stock street tires 195x60x15. What do you think of trying drag radials instead of slicks? also see IHRA has fwd auto.classes I think it will fall in the EF/SA index 15.90 or FF/SA index 16.30. I got a dc sport 4 into1 header and a cat.less downpipe on the way. What about fuel what do you guys think i shoud run. Thanks for all the help.
