Eaton M-90 on 5.0

rcmonster · Oct 21, 2006

First post by new member/new (to me) wner.
I have seen a lot of Eaton M-90 3.8 superchargers for sale on Ebay lately. I was considering putting one on my 95 GT Vert. I'm sure this little supercharger will not make a whole lot of power but it is very cheap to buy it. Anyone know what mods will be necessary to mount this on my car? I can see that I will need a new hood and strut bar. I was going to cowl the hood anyway. How much hp should I gain? What fuel injector size will I need?
Thanks in advance.

That S/C was the one on my GTP. I dont see any way it will work on ur car. You would have to switch ur T/B to the other side, but i dont beleive it would mount on our cars

i've seen them mounted on 5.0's before, not traditionally mounted, though. it was somewheter off to the passenger's side--think they made a custom bracket.

How did they get air into it?

It can be done, but it is more work than you want to do. The boost/power increase is equivilant to farting when you hit the gas.

Check out Jim's Personal Website to see an Eaton M90 installed on an 87 LX. That car belongs to JimBowy, a member of this site who posts over on the 5.0 Tech/Talk side of this site. I don't believe he has any directions on his site for how he went about installing it, but you may want to send him a PM to see if he can give you any details about how to install one on your car.

sick! i bet you could do an 03 cobra blower like that too, the m112

hmmmmm.......I would also wonder about that terminator blower fitting on there. Be an interesting concept at the least....now if we could get 4 valves we'd be good

I'm not quite sure how I missed this post before. I find misinformation like this entertaining at the very least, considering the BBK Instacharger was built using an Eaton M90, but was discontinued due to the price difference between itself and the much less expensive centrifugal superchargers that outsold it. Do a quick Google search of the Instacharger, you'll see there are some people still running them with impressive results.

I found a post on Corral that said they couldn't use the M112 because of fitment issues between the strut tower and the engine. Someone want to be creative enough to give it a shot? I'll let you use my car as a test bed for it

sure, buy the parts and supply the welder and other misc things needed and we got a deal.

Here's a guy who mounted up twin M90's on a 351 (in a t-bird though):

i read that entire website... im impressed. he did a TON of work to make that work out right.

It's not hard at all. I had a custom setup made on my car complete last summer, but scrapped the idea cause I felt like it was just too rigged for me. Wanted something nicer I guess. Hence my turbo setup now. But yeah, not hard at all really. I relocated the coil and made a mounting plate that bolted to the coil bracket which the blower sat on. The blower pulley lined right up and had great belt wrap. The air filter was mounted behind the blower then it discharge out the top going down and around in front of the motor and into the TB. I only drove it once, but it was running like crap because I had it setup as blow through and it clearly wanted to be draw through. Still have the blower.

sweeeet.

that is sweet, subscribing to thread.

cbarr300 · Oct 23, 2006

oh man......that is one sexy twin supercharger setup

zZsKyZz · Oct 23, 2006

...nice...i want one now

96darkhorse · Oct 23, 2006

susbribing.....this maybe worth doing

tjh566 · Oct 23, 2006

Looking into it would be alot of work, He Built custom brackets for ALL of his accessories and he spaces it off the engine it looks like an additonal 3/4", Which on our car we would have to re-loacate the coolant tank and it would prolly need a smog delete, and ALOT of custom fab and creativity, Im still looking into the eaton m90 tho, maybe making a custom upper inake for it to mount directly too and going from there, Prolly need a cowl hood too but I wanted one of those Cobra RR's Anyways.

Mine was mounted right where that driver's side one is.
