yes. but not much.

 

Oh, I would turn it up a few PSI if that is all it would take. People are trying to convince me to just keep the TVS... So much to think about.

 

Raced a 500whp cobra from a 40 roll last night. He got me off the jump because we raced by his rules and his rules said I could not break boost, lol. But the cobalt just cruised on by him around the top of third

 

If you have the money then turbo swap it. Easier to hit 400 lower temps and of course the SNEZZE If not than hold off. No reason to go broke over a turbo.


And this is why I am considering selling the 252et for a 256et

 

nice bro, get some vids of the car running man

 

I'm trying to get a go pro but I don't wanna buy a new one. Once I get on though I'll have videos all the time.

 

Once I sell all my SC stuff I should only be about a $1000 off of what I would need to buy the kit. I think I would get the S256ET, or what ever the bigger one is. What are your IAT2's at with a full pull? Like 1-4th... Mine end at like high 140*f

 

not going to see a gain over the 252 until you go higher boost....personally a 252 is way too much for the car on street tires as is lol

 

you want 400@ 20psi, S366XL... Its just slow spool. If you want a great powerband, then stop worrying about peak HP and build for the powerband with a nicely sized turbo. the 252 will give you great powerband, the 256 can flow slightly more air itll scoot the powerband over a couple hundred RPMs. I think in the end most of you will be happier with the 256et.

startingline- nice run, I love beating up on Cobras, he shouldve been ok with brake boosting seeing as he couldve done it too lol

 

hahah when i brake boost everyone knows my dump starts making noise haha

 

I'm not saying the tune is your problem... I'm just saying it's not perfect. There will still be room to grow.

You DO more than likely have a problem. You need to search it out and find it. Have you checked for a boost leak? It costs $5 to make a tester... it's not that hard.

A pre-turbo exhaust leak will also kill spool times.

This.

The MAF should be fine.

 

I'll have to check everything for a boost leak this coming week. what all do i need to make a tester?

 

Google it. There are a thousand different ways. You're going to need access to a compressor.

 

Lol it would have been fair with his instant boost. But I find it more funny that I won and the turbo still had to spool.

 

yea, guess he started scared and then justified his fear lol. Gotta love it.

 

Who all actually is or has ran the ZZP Turbo stage 1 or 2 cans? Trying to get info because I plan on running them once I resolve my tune issue or figure out what the situation is.

 

<----- 2's

 

Lol i knew you had them. Your the only one? What's your opinion. What's the ower band range? Duration on cams or any info

 

Stage 2 turbo cams are 212/212 duration at .050" with .419 lift.

 

212/212 duration at .050" with .419 lift


my powerband sucked cause of the giant turbo lol. but now we're running a billet 259 on a .55 a/r with a bigger than the usual turbine wheel. so it'll still have a great top end but a far far superior low end compared to the 262.

as far "my opinion", i love them. but i can't really compare them to anything because when my stock engine blew up. it was about 2 months before i sent it to zzp. the last time i've driven a cobalt other than mine was in august of '10. so, i'm just used to it. same with the clutch and everything else. at this point i think driving a stock cobalt would be harder for me to drive than my own built car lol

 

You think the stage 2 will perform good with my 256et? Full Lsj ZZP turbo kit. Is it hard to idle with the cans the car want to stall or anything?

 

you would definitely see some benefits.

no they idle fine. cold starts, and i mean cold as in like 40* air, its rough till it warms up. but driving around they're fine. coming to a stop sign or light or something they won't drop idle and stall out. really nice setup.

 

beautiful that's what i like to hear, who tuned your car or you self tune your car?

 

I has a 09 Lsj turbo!! [wtf]

 

baby turbo
