who has 400WHP on the cobalt ss/tc? what mods do you have and which tune do u have?
Im looking forward on doing some good numbers, but i need the best info available....

Thanks guys!

 

I know someone.........not allowed to divulge.

 

can you hit 400 on stock turbo? i heard yes. I cant imagine traction at HP that high. im having trouble at 300. but i need new tires bad

 

thats scary that much boost and hp will your rings hold or will you have to do internals?

 

there may be a couple out there but they have hook ups if they are.

there will be more at 400+whp once the whole fueling issue gets taken care of....who knows when that will happen tho...

 

400 is scary!!! im guessing you have to do internals..... i dont think the rings will hold with that

 

U dont need internlas even le5's handle 380 whp

 

if you want to reach that HP you have to do SLEEVES!!!!! Trust me.....(maybe because I had a LSJ) mine blew a little over 400. You'll also have to do internals to be safe and make sure you have a reliable fueling system.

 

Bill?

 

Lolwut?

No.

You don't need sleeves for 400whp.

We need a fuel pressure bump

400 whp isn't some mythical creature.

A turbo swap will do it, and we have just enough fuel to do it.

 

you had bad luck there are people with stock block over 400whp.

 

i think ZZP had a 405whp LNF with their bullseye turbo swap and turbo manifold. Check their site, im sure its posted

 

He never said anything about the block.



nub.

 

if i ever hit 400 i would just ****. straight **** on the floor. if i ever went for it i would need a new daily driver though. and a couple grand

You won't get their with the stock turbo.

 

tells you how much i care to fully read anything on this site lolol

 

Can't blame you, you should see what I have to do to ******* post.

 

you can get pretty close on the stock one, but i imagine with an aftermarket one i better be at like 450. i wanna go aftermarket after i run out some warrenty. be a year or two

 

??? I have not talked to Bill in MONTHS sadly

 

no way that tiny turbo will get to 400whp. most i have seen is 345whp from stock turbo and there is pretty much nothing more that thing can do

 

i dunno man. i talked to someone on this forum who is pretty knowlegable who tunes pretty damn good who said you can hit 400. im sure thats after fueling but im not throwing any names out there

 

it simply cant move enough air, after a certain point it just becomes an inefficient compressor. no one has hit a fueling limit on stock turbo iirc

 

what the heck there are guys on here that are doing 400 wheel but not on stock, and u dont need to change internals, they are all forged, except maybe the pistons which are cast. those internals can handle more than 400 hp easy. the fuel pressure is the issue that keeps it from going more than 400 whp right now.

ok this stock turbo is smaller than a 16g mitsu turbo and the 16g is only good up to 375 hp, do u honestly think our turbo which is smaller and moves less air can reach 400hp if the 16g isnt even rated for 400?

 

no you do not. you blew yours up due to detonation. not sleeve weakness.

hi. lets take a trip to the not so distant past.

400awhp has been done on a b16g.
