YEA!





Well, I called Tom (my boost guy) back today, and he said he would do it! He said if I provide the blower/pulley, he will fab the setup for ~$2000-$2500!! I'm soo excited, I hope this all works out. If anyone knows where I can get an M90 or MP90 remanufactored blower for cheap, please let me know, b/c I need to order it ASAP!!!!

Well good luck, I'd love to see this done. What comes with the M90 stock? GTP? Maybe you can find one in a junkyard.

I second JeffesonM!

Don't worry about mileage on a roots.. just keep in mind to change the s/c oil every 45k or so/make sure it's level regularly (you can pick up replacement oil from GM since they use Eatons as well - just about $5-6/bottle - and if memory serves me correctly you can use 2 bottles to fill).

This is a very interesting project... I miss the sound of my M90... please keep us updated as you may have a f'ed up canadian counterpart who might be interested in this next

Well, the last link Jefferson provided seems to be a blower that is close to new....If he doesnt get back to me in time of the close of the first auction, should I go ahead and bid on the 45,000 miles one?

I am really excited!

Slimer, Superchargersonline.com doesn't have any Eaton products. And besides, all the other headunits they sell cost big bucks.

Your right!

Who wants almost full boost off idle?

Who wants that awesome whine?

Who wants Eaton reliability?

Who wants the simplicity of a Supercharger setup?

Who wants gobs of torque?


Crazyness! I better just stick with my lag charger or go with a turbo and prepare to break things.

Using same intake manifold, not mounting on top, no need for hood cowl. Battery will need to be relocated, though.

And what are you talking about "Who wants the simplicity of a Supercharger setup?" It doesn't get more simple than a basic turbo setup.

Well, at least you can dream.

Does it itch? It's not healthy to have all that sand in your vagina, slammed. It must itch!!

Do you want the # of my boost guy? Becuase you can call him if you want. If he doesn't pick up, just tell him Negitive Nancy is calling and to call you back.

This isn't based on "good hopes". I talked to him today, he told me he will do it, and to call him tommorow immediently to let him know when my blower will get here. So unless he bugs out at the last minute (not like him at all) or something freakish happens, it's going to happen.

I think you should stick it on top and do up one of the SS hoods you were thinking about before.

Cool. How much does it take to rebuild one of these??

A torque SC and a VQ30 is going to be interesting. Does this thing flow well enough at the high rpm range also. I don't think the GM3800 motor was a rever so the Eaton didn't have to worry about high rpm stuff

Well, that's the problem with a roots type blower, the efficiency falls way off at high rpm. My feeling is that a centrifugal blower is a better match for an engine that can rev as high as the VQ, but Craig knows what he wants and what he wants is low end power and sound, so more powah to him.

Good luck, Craig! Lead the way.

After reading up on superchargers.com, it sounds like the twin-screw blower offers the best of both worlds.

Craig, any particular reason you're going for the Roots type?

Becuase twin screws are BIG bucks, and hard to find used.

I think the ultimate setup would be an intercooled eaton m90 with a MEVI for more top end.

Today I was at a stoplight, and some guys in a truck were beside me and kept staring at my car and talking. I rolled down the window and they go, "is that thing supercharged?" Yeah. "What kind of supercharger do you have?" A Vortech. "Thats awesome!" Then I gave her a little revv and they started

I wish Eaton made their blowers noisy like the Vortech V1's. I'm really going to miss that V1 blower screetch and especially the BOV. Now, no one will know for sure that I am supercharged at stoplights....that is, unless I revv!

I think I am going to start off at stock boost (3.8 pulley) which is 5-6psi. To do a pulley swap you have to use a special tool to get the pulley off or replace the entire nose drive. I need to start reading up at clubgtp to see if the gains are good. I read somewhere online that Eaton designed the M90 for best gains/reliability with the stock blower, and that upping the boost won't really yeild much gain.

I bet an intercooler would be killer. Having almost full boost off idle means theres going to be lots of initial power potential for an intercooler. I also hear the eaton blowers get really hot which is another bonus for intercooling. We are going to set the blower up so we can make a future FMIC easily.

I think the GTP's redline at what, 5800rpm? So, I wonder how much extra power will fall off after that, to 6600rpm. I am hoping not more then ~1psi.

I am going to have the guy 2 day air the blower to me, but the friggen weekend means that it won't get here till monday. My boost guy said its going to take ~4-5 days to fabricate this kit for me.

I have never heard of anyone being as obssessed and hung up on how their exhaust/engine/blower sounds as you are....how come you drive yourself so crazy over the sounds your car makes???

Just wonderin....

Craig definatly get a V1 dyno and a Eaton dyno to compare to. Tom said he could do it in five days? That is very impressive!

Where is he going to mount it that would not require a hood modification?

Congrats to you, I hope everything works out perfectly.
