Full boost from 1500rpm, bypass valve to give good part throttle gas mileage, and much higher efficiency. If you're good at fabrication, you can pick up a M-90 eaton off ebay for around $350 for oen in good shape and fabricate an intake for it. Should be easy on a 4.6, all the flanges are horizontal and the bolts are perpendicular.

I've never seen a screw type supercharger on a 5.0 Anyone got any pics?

[duplox]

If anyone wants an EFI 5.0 eaton with a m90 I could fabricate an upper intake for it. I'm planning on buyin an m90 for my next engine project anyways.
Is there any interest in this? I'm looking to fabricate and sell either turbo kits or Eaton supercharger kits for Mustangs, and I figure since Kenne Bell's got a nice monopoly goin there is more of a market for a decent cheap screw supercharger kit. Especially if none are available for the 5.0! KB only makes kits for the 4.6? how odd... There are tons of cheap turbocharger kits out there, and that would be a whole lot more work. I could probably put together a nice supercharger kit in around a week and sell the upper intake for ~$300. Add $350 for the supercharger, $300 for new injectors, piggyback ecu or reprogram existing, thats around $1200 for a supercharger kit that'll put a vortech/paxton to shame. Biggest problem is I'd need to find a donor vehicle for fitment and testing. Anyone live in connecticut that wants a supercharger on thier mustang? All fabrication work would be free! All you have to pay is materials! I'm mostly interested in the 80s-93 cars, I think that has the biggest market, but I'd be willing to look at a 4.6.

9psi KB is about $4,700. And duplox..everything you're saying is pretty much true and you always say very helpful things. But I'm going to disagree with you on the centrifrugals being a waste. One word: Traction. I've heard of guys with the 2.2l KBs making 500hp+ barely catching traction on drag radials. I really want a KB. But I can't afford it anymore so I'll probably end up with a vortech or procharger. Sometimes it's good NOT having all that power/torque right of the idle. Lots of people say KBs are ideal for the street..yes if all you want is huge smokey burn outs on street tires. I personally thing a KB would be better suited on the drag strip where you can run slicks. Atleast thats how you could get the most out of it. I want to run low 12s. KB, vortech, ATI, whatever. The brand/style doesn't matter to me. All I want is that nice 12 second timeslip.

[duplox]

Thats true. Thats why I like turbos. I still wouldn't buy a vortech/paxton kit, they're way overpriced.. There are much cheaper ways of centrifugally supercharging a car, either via a used s/c or using cheap turbo parts. But if you don't have time to kill or good fabrication skills/tools, a kit is the only way.

Sounds good duplox, im interested in knowing how your gonna put together this inake maniforld. How much psi are you gonna be able to get out of the eaton?

When you decide you CAN make a 4.6 kit in that price range that "puts the others to shame", you give me a call. You will have a customer.

Will do. 4.6 is tougher though, 302s are cheap and easy to come by.. but if there is interest, I'll buy a 4.6 intake and get to work.

Well you got a customer here if you can get it to work on the 302

[duplox]

I'm going to look into the 302 today. I have an 302 EFI manifold lyin around I could play with. I'll let you know how it goes. I need to find someone who has one around here so I can test for hood clearance when its all together.

[dampachi]

I'd be interested!

Me and Dampachi = 2. And this hasnt even been up for awhile. If you were to extend to forums like stangnet, corral, modularfords, ect. You would get alot of business. I hope you are serious with this, because I am planning on selling off some of my misc. things to get the cash. Id also would hold off on my 4.10s if there is a chance I can get a S/C because I will probally then want 3.73s.

[dampachi]

Highrev87..if you go FI you'll most likely want to keep your stock 3.27s. Or maybe 3.55s if you're the daring type..

BBK had an M90 blower kit out 10 years ago for under 2500 bucks, and they sold a handful. Good luck trying to push an inefficient, undersized blower on people.

[duplox]

The M90 pushes over 90% efficiency, compare that to 75% of a good centrifugal blower. It provides full boost from low RPMs. It can be modified to produce 95% efficiency(porting/reshaping the inlet and outlet). They have built in bypasses to retain part throttle fuel economy. They are designed for 3.0-5.7L engines, so yes a 5.0 is at the high end of the spectrum, but still within its range. Boost would be limited, but it should still be able to hit 8-10psi. Enough for the street. This is not going to be a full out race setup, but a cheaper alternative to the Vortech/Paxton centrifugal stuff. I could build a system using centrifugal turbo compressors with custom backing plates(been done before and it does work) for real cheap, but I'm not a fan of centrifugal superchargers.

Recognize that? Thats a 2004 Cobra 4.6 engine.. on top there is an Eaton MP90 supercharger. The MP90 is the next generation of the M90, both support similar displacements(3-5.7L). MP90s are slightly more efficient, it flows slightly more(~30cfm or so), but they're more or less the same thing. SVT cobras with aftermarket pullies and a good tune are putting down mid-400hp to the wheels. Thats good enough for me, that is my goal. 450-475bhp is what I'm goin for. Upgrade your GT to a quasi-cobra for $1600 sounds nice to me.
