I agree that the M62 is pretty well maxed out. Think about the size of the pulleys you guys are having to run to get 15psi of boost. You guys jump from 3.4" pulleys to 2.85" as one of the first mods. I bet the M62 snout won't even take a pulley much smaller than that. And it wouldn't matter, because its beeing spun so fast that the air in there is to hot to be beneficial.
Didn't someone do the math as to how small of a pulley you could run before hitting the 14,000 rpm max on the M62?
Plus guys, don't forget that PSI is not what you want here, you want CFM. You want to move the most air possible, not just make boost. A larger blower will move more CFM at a lower boost, both are good things.
I'll be pretty shocked if anyone gets to 300 whp without swapping blowers or adding nitrous.
And don't just sit around and wait for someone else to come up with a blower swap kit. Because it may never happen without someone stepping out there and making it happen. I personally wish I had a M62 or M90 to start creating a CAD model of what an adapter plate should be. There could be alot of money in that (and I really want to put a blower on my car). So step out and get this thing rolling, buy a used blower casing for next to nothing, take it to a machine shop and see what they say. Or find a college student (like me) with CAD skills and pay them to create the files needed.

Spinning the blower past 12K on the Eaton is just a waste of time. 12K is pretty much the limit if you want to make horsepower. Now i'm not saying that spinning it past that won't show gains but it will make more heat then it will horsepower.

Does anyone know what the difference is between the 1600AX and the 1600AR by Whipple? Is it just the mounting or is there a difference in the supercharger. Link for reference. http://www.whipplesuperchargers.com/...sp?ProdID=1162

Looks to be just the way it mounts.
BTW - If anyone was wondering. The 1600ax is a 97cid blower. 7 more cid then the M90.

utoh, the SCs youve listed on your first post are the wrong SCs. GPs have the gen III and V SC. They never got the Gen IV. Also, the Cobalt has the Gen V m62, not the Gen IV. It is a completly different SC outlet than what you have posted. Also, im willing to bet it has a different bolt pattern also.

If you're going 300hp or over you are probably going to want forged pistons. I'd say you may get upto around 280hp with the stock compressor which I would consider the climax before you have to swap pistons, swap compressors and fabricate the adapter plates (which is more of a science than lining up bolt holes) get an a/f controller.....and the list goes on.

Since when are we talking about grand prix's? I posted a picture of the M62. Plain and simple.

What are the options as to say a centrifugal type blower over a twin screw?
I beleive a SC swap is in need if you are shooting for 300WHP.
I myself are contemplating removing the SC and going to a single turbo down the road.
Depends on how well the cobalts will respond to power over the next few years as mods begin to come out. I hope the aftermarket world for this car explodes.
We will never know the problems associated with thins kind of stuff, or how well it all works untill someone actually does it.

Why would you want something like an ATI or Vortech blower? 4Cyl's need low end torque and a centrifugal doesn't provide that. I imagine a novi2000 kit would be fun but the mounting would be a pain in the ass.

a novi 2000 will be way overkill on a cobalt. MAYBE a novi 1000, but thats it.

What version of CAD do you have, I've been trying to get a new copy. I'm certified but not liscensed....Got any connections to getting the program,kinda hard out here where I am(and I don't want to pay the 5K from AutoDesk unless I have to for the full version). Thanks.

the m90 is what ive been looking at so far, but the other thing ive been looking at is makeing sure the pully on the snout lines up with the other drive pullies...im waiting to get one first so i can take some measurements and get it over to a shop to see what can be done...im waiting on my local yard to get a gran with one first

You can buy different size snouts so the pulley's will match up.

I could be wrong but if I'm not then you're just getting the added advantage of having no turbo lag on the bottom end, and no parasitic loss from a blower on the top end.
I personally think it's a cool concept, but wouldnt want the pain in the ass of a turbo in my car. I'd much rather go to the wipple charger. Who cares if it's a parasite...it's a friggin monster, it'll give you back more than enough to make up for the drag.

it depends on what your after, some people are willing to trade a few lbs/ft at 3000 rpm to make a few more lb/ft at higher rpm with the corresponding higher hp. some people are dyno queens and some people actually want their cars to perform. not that 300 hp is gonna be slow no matter how you get it...

Plus for the money, you could do a twin screw and still have enough change to fund a trip to Mars.

Dyno queen's crack me up. They only want the highest hp numbers so they can brag to there friends. Pathetic
