fwd cobalt stocker
 

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. :cool:

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. :cool:

Re: fwd cobalt stocker
 

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.

Re: fwd cobalt stocker
 

You need a low profile drive tire that will hook. You have to use race gas that is approved as street fuel will not pass tech.
I wouldn't worry much about the engine for now. Get a good convertor, better gears (if available) and stiff front shocks for better traction. Low powered cars really benefit from light wheels and tires.
Always pay attention to your MPH. That is your own personal dyno. ET is relative to MPH.

Re: fwd cobalt stocker
 

VP C-10 is unleaded & 98 motor octane. It should do fine.

Re: fwd cobalt stocker
 

Jeff on the tires there is a problem m/t doesn't make the 20" tall tires anymore.
Another thing is to stiffen the rear suspension as much as possible weight transfer is your enemy.

Re: fwd cobalt stocker
 

Thanks for all the info.guys,Greg checked out C-10 race fuel from what I see it should work just fine Thanks. Talking about fuel, how do IHRA and NHRA do fuel checks ? do I need to have a way to get fuel from the fuel rail? If so what do I need.Any other help anybody has will greatly be appraceated. Thanks again looking forward to running stock classes and having some fun.

Re: fwd cobalt stocker
 

I us C10 works good.

Re: fwd cobalt stocker
 

Tony, I use a fuel pressure test gauge that screws onto a schrader valve on the fuel rail. My gauge has a pressure relief valve and a short tube coming off of it so I can drain fuel right out of the fuel rail.

Re: fwd cobalt stocker
 

I should have been clearer. You can not have any street fuel contaminating the race fuel. Fuels is some parts of the country (like where I live in AZ) have chemicals that NHRA does not like. If contaminated, you will be DQ'd. It's a long process to cleanse the syste,. I know, I would drive my car to an NHRA event and flush it out. But then when you get that #1 qualifying position, it's kind of worth it! ;)

Re: fwd cobalt stocker
 

Owen, Thanks for the info on the fuel pressure test gauge.Jeff I will be draining the tank of all street gas and running C-10 thru the system before I go to any events,Thanks for the heads up.

I would like to wish all a MERRY CHRISMAS and have a safe and happy holiday from my family to yours,

Re: fwd cobalt stocker
 

That's what I did with my car. It takes more that draining because you can't get every drop out. It has to be flushed with the race gas. My pick-up would get the first batch of race gas after it was flushed through the system. My '72 F100 360with 8.0:1 compression didn't run any better with C-16 and the wallet sure didn't like it! The filters sometimes need replacing. It was a real pain in the you-know-what.
