sounds like pulley size on the mp62 blower. I believe stock is something like 3.4 or something.

you'll probably be at more than 8psi with a supercharger

Leafydialupking

more like you'll be at around 13 with the 2.8 pulley on a 2.2 with a stock head and cams.

redcobalt07

yeah and you shouldn't blow your engine up either with that setup

stock puley is 3.35 close enought to 3.4 though.

Okay so maybe I heard only 8psi for turbo? Cause 13 sounds like a lot for my tiny little pistons haha can you get a boost control for a sc? I think that'd be the most dependable way to go; keep it low daily driving then turn it up for some fun.
I need to find a totaled 07 ss/sc somewhere and buy the whole block haha too bad theyre VERY difficult to find in junkyards. Hell I may even get an 09 turbo block if I could find a decent price

1. yea, i said 8psi on a gt28 turbo
2. 13psi from a supercharger wouldnt harm your engine
3. to my knowledge i dont think there are boost controllers for a supercharger, maybe a by pass valve or something
4. if you seriously want a lsj or lnf, trade in your cobalt, alot easier then tryin to get a lsj or lnf block in and actually work

JWhit197

Okay well I didn't know it wouldn't work I won't be doing anything like that. Trade in isn't an option cause I'm still paying interest.
So what's a good aftermarket sc kit? And I'm assuming a stock 07 ss/sc would work as well without many modifications?

05-07 stock supercharger kit will work. or you can go to zzp to get a supercharger kit. in my opinion, supercharging is a waste of money on a 4 cylinder, you make a hell of a lot more power out of a turbo then a supercharger. thats why you see lots of people with supercharged cobalts go turbo. you can get a turbo kit for a little more then a supercharger kit

I went supercharged and I love it.

BlackCobalt707

iTrader: (5)

lol, its fun, but a turbo kind of guy. im not tryin to be bias towards turbos, but facts show you make more power on a turbo then a supercharger. and like i said before, its just my own opinion.

Glowbalt

iTrader: (3)

It is true

Leafydialupking

I looked at it this way. SC was easier to install, easier to tune, and made power where I wanted it for a daily driver. Now if I was making a track car or was starting with an engine that already had more than enough power down low (v8) theres no question I'd be going turbo. The roots blower just makes sense for a daily driver. And either way you're only going to be able to make 250 hp on the stock internals before something breaks.

JWhit197

That's exactly how I feel. My internals are limited to only so much power whether it be tc or sc.. Being that sc is the safest, and will give me plenty of the power that I want as a daily driver I think it's the better route for my situation. Now if I do decide later on the road that 250whp isn't enough, Ill rebuild the internals, sell my sc kit to another kid just like me right now, and convert to a turbo setup.
But yeah I'd love to have a brand new kit from zzp. It says that the stage 2 kit still only comes with 3.1" pulley and 11psi is the 2.8" pulley available? And I'm sure the boost could be increased to 13 with the tune right?

or you can just stay SC'd and go TVS with smaller pulleys and cams

tvs 2.2, sounds interesting

BlackCobalt707

iTrader: (5)

this is true. but wats the point of tryin to make good decent power and leavin it at that? thats like gettin a girl wet and not hittin it..if youre gonna go that far might as well pound the **** out of it lol

you will save money by going with one. you buy a kit full price and try to sell it and youll lose money off of it

cost me around $1750 to sc my 2.2.

Currently running 11 PSI w/ my 3.0 pulley and cooling mods.

Looking into a 2.9 pulley. Getting dyno'd on Saturday hopefully.

Leafydialupking

iTrader: (1)

I can make more power than the stock bottom end can fairly easily, I just need an exhaust and then cam and I'll throw a rod like tom brady throws footballs. And I'm not going to rebuild it with forged internals, I'd much rather just do a 2.4 bottom end swap and have a freakotec.

JWhit197

Definitely let me know what the dyno numbers are I'd be really interested to hear.
But $1750? Where did you get it from?
And another thing I was thinking was related to the transmission.. I have an automatic and I didn't know if the sc kit needed to be made for an auto or if it didn't matter. Also, how long will my stock tranny hold up on 13lbs of boost? I can't imagine it being too strong..

redcobalt07

iTrader: (18)

the $1750 probably cost him the tune, bolts, miscellaneous parts, the heat exchanger, manifold, intake, etc. The auto trans actually holds up stronger than the manual trans so you will be fine there. I make about 220whp with a stage 2 sc setup on my 2.2. I have a friend who makes 251 with his turbo 2.2

JWhit197

I gotcha but I'd probly go stg 2 zzp kit then the 2.8" pulley at 13psi. And when you say holds up stronger how much stronger do you mean haha I already have about 82k miles on original tranny and engine.. cai at around 65k and i probably wont be doing f/i til about 90 or 95k miles as a daily driver.
