Alright, I've been thinking about doing a custom supercharger on my car. I want to use an Eaton M-90 supercharger found in mercury cougar XR-7's, T-Bird SuperCoupe's, Pontiac Bonneville SSEI's, Pontiac Grand Prix GTP's, etc. I mainly want to use it because you can find them in junk yards and on eBay for like $300. Also, its made for a slightly bigger engine so it will provide plenty of boost. The main problem is finding a place under the engine bay to stick it and have it driven by the belts. The physical dimensions of the supercharger are 16.5" X 8.5" X 6.5".
I'd actually rather use the M-62 supercharger, its smaller and more suited for the application. The problem is you can't find it on an older car in a junk yard, and I'm not spending $3,000 for one of these things. I'm doing this custom and cheap, I'd rather just do a TT conversion.
Here's were I was thinking of putting it:
The pulley I circled in red is to the power steering pump I believe. I wish I could do away with the power steering pump, but this car needs power steering. I think I might be able to drive the SC off this pulley and still keep the PS pump there. The space between the back of the engine and the firewall is pretty close, think I can fit it? Can you drive a supercharger off a smaller belt like that one, or will it slip too easily?
I would want to make some custom brackets to mount the supercharger and then do some custom piping down to a factory TT intercooler on one side. Do I have to get metal piping custom bent to go everywhere, or can I make it out of PVC pipe. I know its really hot there by the back exhaust manifold so I dunno... I'll get VR-4 injectors and fuel pump and all the a/f controllers, etc. I'm doing this all myself and if it is too crazy and the cost is too high I will abandon it, I'd do a TT swap instead.
If I can't fit it back there, I was thinking about running a shaft to the other side of the engine. I could fit it where the stock air box is, etc. I can also have stuff go higher, i'll cut a hole in the hood and fiberglass some kind of scoop there to give more clearance.
So do you think I can ever pull it off? Any ideas? Any other cars with stock superchargers I might consider?
