I'm looking for a stage 2 pulley and hub to put on my cobalt ss, if anyone sees a problem with putting this pulley on my car without the injectors and tune from the stage 2 kit let me know. I dont usually beat on my car im just looking for that extra power and that peak boost of 15psi. Im concerned with all the other pulley systems because most have the polished 3" pulley thats why im looking for the stage 2 system thanks.

 

They are hard to find ..... If you add this to a stock SS/SC it's going to be very lean up top and most likely cause damage . IIRC the stock tune will bleed off boost at 12.5 psi anyways .

you'll probably blow up.Your injectors are already close to maxed out.I wouldn't recommend it.

 

I have a 3 inch pulley for cheap man

 

What are you looking to spend on it? They are hard to find used since it is a gm part and companies make smaller pulleys that fit that hub. You might be better off getting the whole stage 2 kit from crate engine depot for 550.00.

 

You can get an aftermarket pulley and hub cheaper than a stage 2 pulley and hub.

 

there is one on ebay right now

 

Thanks for all the help I'm debating now whether to get it due to peoples responses, but i do know that denny on this forum did run a 3" pulley for quite some time safely.

 

hey man i got a 3.1 pully that i had on my cr with stock injectors an gave me a big BIG gain. with not one problem. pm me if your interested...

 

it's your car, i;d like to see the AFR and IDC of stock injectors with a 3.1'' . I'll bet it would help you decide .
