I have an '07 SS/SC (Yellow). Right now the only performance mods i have are Stage II, the airbox mod with K&N E-1009, and (in a few days) a headers-back exhaust. i was planning on buying a smaller pulley, cooler spark plugs, a tune, and a CA heat exchanger. (And a torque dampener and tranny mounts)

I was just wondering at what point am i going to have to start getting any internal mods to my engine. I don't want to blow it before i have some fun. any info would be appreciated. thanks guys

 

how much smaller of a pulley are you talkin...if you stay within some reason you will not need to mod the internals to handle what you have ...with the h/e and the tune...u should be fine.

 

Do stage 2 and all the bolts ons and call it a day. Be plenty for you around 250ish.

 

280 feels really good in this car. That might be the right amount. Not for me though. I need more, always need more.

 

If you cant put the power to the ground then you have too much. Its cool to say "I have 4000 hp" But if you can't drive the car its stupid.

 

I have 245hp/215tq and I am quite happy, of course I want more, but I have other financial obligations that I need to get in order before the car can come up for expenditure again, and I have to say 3rd gear is a f'in ball in this car with my mods

After a few months goes by I do plan on going with headers, downpipe, dual pass plate, and maybe a new H/E before I do anything else major

 

I keep telling myself that when i get to 275 i'll stop but i know i'm lying to myself. lol.Thanks for all the help guys. any more ideas would be appreciated

 

4000hp is rediculous and is not obtainable on the street. Or at least on pump gas. My goal is 1000rwhp in my z06. 440 was at first scary. Then it was fun. Now it's alright. The car totally hooks, which is great but now I am ready for a big CI turbo setup.

 

i backed my car down in power, it was too much in the corners. well for what i use the car for it is.

was sitting about 275 to the tire. i dropped it down to 260. nice balance in power

 

You also gotta ask yourself, is this your daily driver? Do you want warranty? Do you want reliablility, because after a certain point all those go out the window, i learned that the hardway with my last cobalt, so this time iam going to tone it down a bit.

 

Damn you and your race gas!

 

it was silly!

now with the full exhaust and 3.0 it's a good balance in power

 

So what will I be with the new mods? yours is well balanced... mine will be.....

 

i want to break 400whp in my cobalt with the nitrous. my camaro is somewhere in the high 500's to low 600's to the ground.

 

Thats a lot of nitrous.

 

I"m with Zinner here, that is going to be a lot of nitrous, there are a couple members just barely making over 300 with nitrous, you are looking at like a 100-150 shot with some good mods to be at 400!

 

300 Fwd

 

Our internals are very strong if modded appropriately. Which means, all the cooling mods MUST be done.

 

i think 10:1 coated diamond pistons, and a 100 shot with a 2.7 pulley should do it car should be done saturday afternoon

 

Well in this book i have it says: "GM Racing dynamometer tests confirm that major HP gains are possible w/ minimal mods. For instance, when building an ECOTEC engine up to 400HP level, no mods. to the cylinder head, block, main girdle or crankshaft are required." but if u go over that you will need to replace the block and install all those other parts. And really its easy to get 400HP out of these engines w/o the help of a NOS. These engines are also proven reliable and effective up to 11,000rpm. Hopes that helps out.

 

Man, I don't get it with the uber high compression pistons on a boosted motor! Maybe it's just me but I was always under the impression that lower the better!

 

because i like nitrous and nitrous loves compression. plus 10:1 isnt too bad for boost. the biggest thing is going to be heat, but i have a few mothods to cure that

 

lots of fuel can keep it half ass streetable

 

To who ever is hitting around 260 hp, what mods do you have. Thats around were I want to be.

 

IMO there is no such thing as too much power. there is never enough power. da mo powa da betta..
