Hello everyone,

My name is Brandon and I'm new to CobaltSS and I just wanted to check and see what MPG everyone is getting with the Hahn Turbo Kit on there 2.4L automatic? I'm just wanting to get some figures in my head because I want to be quick but not be a gas hog either.

 

your not going to lose THAT much, and welcome!

 

welcome brandon pretty sure celica would chime in

 

Thanks guys, I appreciate it.

 

Well i have ti on my 5speed 2.2 and went from 38 down to 28. Sucks but thats what my civic is for.

 

it depends on how soft you drive... lol im sure having a TK on your car will make you lose MPG because you might get on it more.... i know i would...

 

I just drove 700+ miles at 65-70 on cruise and managed 28.8 MPG

 

lol well then... im just saying

 

im at 19.5 mpg driving in the city alot i can't even imagine when i slap the s/c on there

 

wow you get terrible gas mileage.... get on it much?

 

seriously i used to get 22mpg with my ss/sc when i would get on it all the time, now i drive easy and get around 25

 

Dont tell me your getting a turbo to try and get better gas mileage. I hate when people say stuff like that.

 

that is the reason chevy switched from SC to TC...more efficient!!

 

No No, I'm not getting a turbo to get better gas mileage. I'm just trying to balance the two out. Quickness & MPG.

 

Ouch 10mpg loss is huge. I wouldnt expect that much of a loss, it seems like it would be 5 mpg tops, seeing how the FI ss/sc gets nearly as good of mpg as the lower balts.

 

damn i get 30 plus cruising on the highway...... just dont hit boost and your good.

 

When cruising the kit should use no more fuel than stock.

 

Well see the Cobalt is the only ride I got. And I use it everyday to go to work (daily driver). Well I work in Charleston, SC which if you haven't ever visited there, it is stop and go traffic. If you guys think the turbo idea is bad, do you think I should just stick with the basics like intake, exhaust, and ECM & TCM tune and call it a day?

 

I agree however as stated before having a lead foot doesn't help any. No offence to anyone.

 

i would stick with what you said and go no turbo....if you have the money buy a beater car and upgrade your cobalt to what you want...

 

I was thinking the same thing nhanson.

 

qft and paul was making about 28 mpg on his turbo setup .. so no one can bitch about turbos making them lose that much.. there's no way you're losing 10 mpg in any way shape or form.. hell the 2.0 only gets aobut 5 -6 mpg less and thats more of a mpg ***** then a turbo is

 

actually if you drive easily and shift under 3000 everytime you WILL see better gas mileage...hahns even proven it with there kits....but dont shift right at 3000 im talkin like 2200-2500

 

more like driving like your grandma....

 

you mean... drive like you should for good gas mileage lol.. any higher then that on turbo and you'll be hitting full boost usually so no **** you'll be getting worse gas mileage lol
