Saw this on another forum. It uses the old M62 supercharger found on 92-95 GM full size cars with the 3.8L SC motor. The Superchargers can be had for < $100 and this is $200. Not saying it’s the greatest idea, but it is an interesting idea for forced induction.
Build you own supercharger system! This is a new, low profile version of our supercharger adapter.
One of the hardest parts of adding a supercharger is connecting the blower to your motor. The Eaton M62 blower (found on early to mid 90’s Pontiac Bonneville, Buick Riviera, etc) is common and easy to find. The size makes it perfect for boosting many 4 and 6 cylinder motors. But the mounting surface is oddly shaped and the holes seem randomly placed.
This item fixes that problem! It is an adapter that bolts to the odd shape, and gives you flat, square, easy to work with mounting points. Its made of cast aluminum, and has four mounting holes on the flat ends. All holes have military standard thread locking inserts installed. There is plenty of extra material and flat surfaces if you need to add your own mounting holes.
Rather than the removable outlet of our other adapter, this one had the 2.5" tubing outlet machined right into the casting. This still allows easy connection of commonly available 2.5" intercooler/turbo hoses, but is more compact.
This auction is for the adapter only! The supercharger, intercooler plumbing, motor, car, garage, etc are NOT included.
I had a friend do something similar to his 1980 Mercedes with a Ford 3.0 V6…ran pretty well actually! Definitely not glorious…but on the cheap it works.
the only problem I have here is that they are essentially taking away all the benefits of a roots blower by running piping from it you intercooler to throttlebody/carb…at that point you’re better off with a centrifugal supercharger for the better efficiency.
Belt routing and mounting seem like they’d be a big issue on most cars. Also I’d be curious how easy it is to recalibrate cars that weren’t designed with boost in mind. Interesting idea though.
I have a setup similar to this for a eaton M80 that will be going on my 1990 taurus this year. It should add a little spunk to the old girl.
not really. you would have a bit of boost lag but at least you would still have good boost at low revs. There is always the option to build the crazy contraption like a guy on SHOforum did to get good low end performance out of a centrifugal unit by spinning it at its design limits to produce much more boost that his application would permit then regulate boost with a mechanically regulated throttle body before the supercharger. That was his way to reduce the late boost effect that centrifugal units produce.
benefits? I say hardly. Especially on small engine cars that most of us on here use. Most of the roots style setups that compacts either have plumbed cooling from the manifold which eliminates your “roots benefits” anyway. The only way to “effectively” cool a roots setup is a shortstacked heat exchanger right between the blower and manifold. I actaully really like the idea of a small adapter plate like that because you then have to freedom to put stuff whereever you’d like, which is a huge benefit for fabbing something up in a compact cars engine bay where there is very little room to play with in the first place.
its not even close to the same application but there are a few SHO’s both V6 and V8 kicking around with M80 and M90 blowers setup like this. The power delivery is fantastic for really cheap. Not going to make huge numbers but 80-120whp gains are common on SHO’s If all the fab work is done by yourself it can be done for 1000-1500 including tuning on the sho’s gives it a little kick that the car really needs.

If you put a M90 on your SVT you better hold on to your ass.
Turborcharge anything cheap: Buy a turbo off ebay for less than that adapter plate costs. (Oh yeah but in either application you need $$$$ in supporting tech)
the setup i bought for my car actually came off a boosted dune buggy. The blower bolts where the AC compressor goes. I don’t think I will run a intercooler. I don’t want more than 8psi because I still want to road course the car often and I don’t want to deal with breaking 3rd gear… it is not installed on my car I don’t have picture of my car completed yet.
other cars. This is a big power build goal is north of 650whp
I can’t find any of the threads with decent pics. There was a guy that cut a whole in the hood fabbed a box intake and made 250whp on a m90 for less that 500 bucks. it was a school project or something. it looked redic but was kind of neat.
