ill be waiting to see this thing run.

 

If you ever ran it on pump gas, what do you think you'd make on 91 octane (or whatever octane you have as premium, its 91 in AZ)

 

 

There are worse things to complain about.


There are a "few" of us waiting for that.



We have Chevron 94 up here which is what I will be using. The plan is to use pump gas + meth for the track. I don't plan on driving around all the time with the boost turned up. Only the days when I feel like hunting some big boys.

 

you're gonna have to drop the boost A SHITLOAD from your track setup if you plan on making 750rwhp. Pump gas is not gonna be too happy with the kinda boost you are gonna need to make those numbers on a 2.0l.

 

We will see how that all works out when we start tuning.
I have no problem running race gas at the track if needed.
As for the street I will be happy 90% of the time running at 400-450rwhp.

 

yea, i doubt you will be able to achieve 750whp without race gas. 400rwhp is definately doable though and with rwd that thing will be a monster. Your car is likely going to be quite a bit heavier, but still fairly light. Even if you only make 500whp over all which you are going to blow past, you will have an easy 10 second car. LOL people are gonna be so confused when they see a cobalt roll up with slicks....in the rear

 

underdog ftmfw!

 

red....im not gonna lie...your a one smart **** when it comes to this ****, cant wait to seeit at a meet!!!

 

What are you doing about weight? Stock the car is 2900 lbs, add in 500-600 lbs for the RWD drivetrain and you have a 3400-3500 lbs COBALT. Weight reduction is a MUST

 

600 lbs for rwd?! that's quite a ****** bit my man! i'd say 500 maybe a bit more for the 9", the ds, all the other drivetrain components, and the turbo setup which will outweight the stock blower setup. A 3400 lb rwd car is not going to really be that bad for the kind apower he is gonna be making. My car is about 3350 and one of the guys on the forums making high 300's to the wheels is running low 12's in an automatic with...i think stock gearing (which is 3.31:1 in my car). if he only makes 400whp on a street tune it will still easily be an 11 second car. VERY EASILY. if he makes his goal of 750whp, we are talkin 9's.

 

Yeah, but it would bug the **** out of me, knowing that my car was toating around an extra 500 lbs. Also you have to remember hes also using a much bigger heavier tranny, so that contributes the extra weight.

 

Yea but where the hell are you getting all this weight? he could get an aluminum driveshaft that weighs under 30 lbs and is strong as ****, the rear end is gonna weigh nowhere near what i think you are expecting it to, and he is using a t-56 right? That sure as hell isn't 200 lbs heavier than the tranny you got. Alot of the weight is gonna be up front too. As long as it is distributed it really won't be that bad. You can't expect this thing to weigh as much as an s2k and make massive amounts of power like he is expecting. once you start making huge amounts of power like he is expecting (750whp) it becomes more of a battle of traction and power than hp/weight. A 3300 lb car with 750whp could be just as fast as a 3k lb car with the same power if the latter doesn't have quite as good of traction/the proper gearing. With massive power like this you want to focus more on weight transfer and getting the power to the ground than weight itself. Once he gets passed that, then he can worry about weight.

 

tombomb, I need to say that I am not the one doing all the work or design. My being a "smart ****" is limited to knowing enough to do it right the first time and minimizing the chances for a catastrophic failure.
I am also smart enough to accept that I do what I do well so I can afford to leave this in the hands of those, who do this well.



Well before you add up the new components make sure you subtract all we are getting rid of.
Plus as 8cd03gro stated we are using some custom parts that will be lighter than stock.
The driveshaft & brakes are just a couple that come to mind. All components that will be new will be for racing, so weight is already factored in. The rear axels aren't going to weigh too much considering there won't be much once the cars tubbed.
We are also having no back seat area like the stock and what is back there will be mainly fiberglass. Also the chassis we are using will all be chromoly.
Yes we are adding some weight because when we cut up the floor/trunk area we are not using aluminum because I am building this car to last.
Also we will be running a fuel cell which will be smaller (likely only 9-10 gals).
There is no doubt we will be a bit heavier but again as 8cd03gro stated, with 750whp I can afford a bit of extra weight. After all is done I will have the car weighed to see where we come in additional weight.

I found an article about the T-56 and that tranny only weighs 130lbs. Our stockers weigh about 70.

 

Damn Victory, I'm making the drive up into Canada when I get back just to check out your car. I'ma going to PM you to death till I get a day your going to the track and meet you there, because I really wanna see this thing run before I have to drive cross country.

What I would really love to see is your car go against my friend D's Maverick (Spaceframe, Tubbed, blueprinted 428 Cobra Superjet, massive Whipple SC). You won't have as much power as him, but you weigh less.

If your anything like him, you'll need a wheelie bar in the back of your car. Can you imagine that, a Cobalt pulls up to the drag line with a wheelie bar on the back? Everyone would be seriously like until you ran. Then they would be all

 

Once the car is done and ready to go to the track I will let everyone know.
I asked about the need for a wheelie bar and because of the 4 cyl torque and slight turbo delay we "don't" expect to need them, but time will tell.
The concern I have is needing to put an fugly parachute on the back.

 

Yea, but at least the parachute can be taken off for street driving. D's car seriously needs the wheelie bar from the combo of big ass V8, big ass Twinscrew, and way way way to much torque. But it was cool watching it with the front tires off the ground for the first 10~20 feet, then bounce back off the ground again with the 1-2 shift.

I'm willing to bet that you could launch it so your front tires hopped off the ground. Your tranny might not enjoy it much, but you could do it.

 

The chute seems to be a question I won't get answered until I talk to tech. I can run in either super street or super gas and they don't expressly say I have to have the chute. However the NHRA rule book says "Parachute 7.50-9.99 Y" The chute's mounting points will always be visible. As well I need to have an master electrical cutoff on the rear of the car. Do you think that might give away my "sleeper" Cobalt? That is if they miss the huge tires on the back.
I guess time will tell about lifting the wheels at launch. Good thing I am rebuilding the T56 before it goes in.

 

very nice

 

nobody is going to believe the car is a performer, just a pretender...lol

oh your custom plate should read "justa2l"

 

That would be priceless. Just a 2L indeed.

 

That would be a great plate.
I am thinking I am either going to have to rig up a dvd cam or always have a passenger filming just to catch some of those "priceless" expressions while I am out "pretending"

 

Okay, so some more info about the project.
The car has been moved to another shop to do the RWD conversion/chassis work. After several times of being told the work was being started it never actually happened. The original shop is a small operation and way to busy to do the work. I guess thats their price for doing quality work.
The new shop is really excited about doing the project. Actually they are really excited about doing "more" of the project. The person now in charge is Keith Losier, who some of you know as a member on here as well as the owner of Desired Customs. Keith and another shop have merged to form a "one stop" shop. Check out the new website, particularily the T-Bird in the video clip. www.theautodreamgroup.com
Next, we have shipped out the stock cranshaft to get the custom one made up. The company http://maciasracing.com/index.html will be doing a custom Billet crankshaft complete with everything needed to just install into the engine. This may take about 5 weeks to get and I will let you know when we hear more.

 

good deal man., I've heard some very good things about those guys. I think they'll have you up in running in time to meet your goals no problem.

 

We have talked with Garrett about which turbo to use as our big turbo and the plan is to use a GT4094R. This is a monster turbo and before everyone tells me about all the lag with a GT4094R, remember the reason for the smaller turbo.
The fun part will be fitting the turbo in the engine bay. For specs go here, http://www.turbobygarrett.com/turbob..._751470-22.htm
