the TVS is an awesome idea. It's more efficient and will make power more safely than the stock M62. Once you really start getting into dropping pulley sizes and tuning your computer to deal with that along with all the cooling mods. I don't see the warranty remaining valid anyways. I don't think GM intended on warrantying a 300whp Cobalt, so just go with the TVS and make that power as reliably as possible.

 

100 shot

 

Or he could buy your rims. I want those so bad but can't afford them

 

Ill take it one step at a time..get the supporting mods like exaust and injectors and what not get it tuned and then ill finnaly get the supercharger..lol
ANd i love those rims i was gonna get them soon!

 

You'll have to re-tune with the 1320 so you might as well do it all at one time. lol

 

Ehh i thought i could tune it and then put it on..ehh idk yet..lol..really want too put..warrenty over more hp?..hmm

 

If you are all caught up in your wanting the warranty, walk away from modding. It gets no simpler than that.
I started to mod a car with a 5 year warranty and 1 year later I threw the last 4 years away.
Make your decision and live with it.

 

you don't need a tvs for 300 bhp. the ls4 tb is a waste. period.

simple mods work the best.

header
downpipe
2.8
60's
intake
water injection
tune file.

or you can do a gm stage 3 and have 300 to the crank on 100 octane. up to you

 

first option sounds good..and if i get that stuff..it kinda sets me up for the TVS..all i have to do is get and exhaust and the TVS and a new tune?

 

header downpipe catback. to get the tvs dialed in it takes a bit of time of minor tweaks here and there

 

I might be confused then, do you or do you not need the LS4 TB for the TVS? I would imagine with your set up probably not because you're only pushin 18 pounds.

 

You can run either or, most dont like it becuase of how touchy it is.

 

Ok....I was thinking because of the added airflow of the TVS that the LS4 TB was needed but now I know.

 

No it does provide gains most just dont feel like wasting the time playing with the tune to get it to work properly

 

I guess that makes sense. I'm hoping to be able to step up to the TVS within 6 months or so. It depends on how many more cruises I pay for...lol...

~320 FWHP sounds awfully good to me.

 

It moves damn nice the car is a totally different animal it never stops pulling.

 

Yea, but as I mentioned before I need to either find someone who can tune my car for it or I need to take the time to figure it out myself. But it's gonna be hard to do without HP Tuners.

I do need to read more about that charger though but theres so much misinformation out there it's hard to sift through and find the useful points.

 

320 fwhp sounds very good...lol considering thats what i wanted to get anyway. but

header
downpipe
2.8
60's
intake
water injection
tune file.

would all of those voide my warrentty?..i have the intake soo scratch that off it came w.the car..would the others voide it though?

 

Most likely yes, however if you went back to stock if something happend your warranty should follow as long as the dealer doesnt know about it

 

But hears a question..everything in the car is pretty much stock..you cant see the tune..u cant see the headers or downpipe..the 2.8's everyone over looks them..the 60's are inside the motor so u cant see them..and the water injector well where would that be..
what im trying to get at is will gm really notice?

 

yep, that stock pulley is big and black not small and shiny, the tune they can see with a tech two, the can see your exhuast and intake. They know what to look for.

 

ugh, your kidding me right an exhaust will really voide the cars warenty?..
