Too small I would think. jmho

 

You would suck the guts out of the supercharger, or spin it at 80million rpm to make it flow hot air into a 5.7. Its made for a 3.8 and even those guys make the thing run out of steam when they start making a fair amount of power.

 

i was thinking the same but in a 3.8 motor it makes 9 psi and with a smaller pulley in a motor with 2 more liters i would think it could possibly make 6 which would be all i would want on a stock block.

 

i can sell the m62 for what a m90 would be. would it do the job?

 

I am still saying hot air thats not worth a crap. Not to mention the 15 year old blower you are speaking about I would say not worth it. My buddy Tom had a GTP with a small pulley that made about 14#s of hot air(low timing), went down to about 12 (higher timing) when he went A2W intercooler but still not the direction I would persue on a 5.7.

 

what are the options for my application?

 

I doubt you could make much at all, the newest model on the cobalt SS' make 12 psi and up to 22 on a 2.0L motor. This is the very newest model. The one off of that car has to be a early gen eaton M62 and i bet it's not near as advanced as the new ones. It would be a major waste of time and money to fit that to your GTO. Your best bet is to just purchase a kit and not have to worry about all the problems with making something like this work in the S/C sense unless you have a shop full of tools and machines

 

the series 1 m62 was to small for the 3.8 , as well not very efficient the pulley on that m62 was very small to begin with

plus the amount of work to try and get it to work your better off getting a new kit

youve got prochargers , maggie 112 and 122 , and several turbo options

 

i do have a couple turbos at the shop setting on a shelf. i just don't think they last as long, sound or look as good as an eaton.

 

Uh, sound and looks are subjective, but (generally speaking) there is no reason that superchargers last longer than turbochargers. Assuming it's water cooled, and that you take care of it, they will last as long as anything else.

 

Hmmmmm, 80% effecient or 35% effecient???? I say Turbo all the way. We have a knack for them though and love the sound of raw HPs being packed into the cylinders.

 

call me old fashoned

 

i dont even know what to say.... just don't do it. Like said above for the money youl spend to fab it up just sell it. Then buy a used kit on the board.

 

i want to keep the car i have stock since it's a w40. thinking of buying a salvaged one and brainstorming for things to do with it. never had a turboed car. the only forced induction cars i've had are 93ssei, 1938 nash 455 w/708. love the wine!

 

An M62 is way too small. The M90 is too small for even the GTP. They have to spin the shit out of them to make alot of boost.

 

Do not waste your time with an MP62 on a 5.7L motor. 2.0-4.0L motors is their happy place.

 

Scape Goat I have an M62 on 350Z Nissan, It maxs out at 8 Psi on a 3.5 Liter engine, I doubt that you even get 4 PSI.
