Hi,

I really need help on how to supercharge a Rover V8 engine.
Spec is 3.5l with offenhauser inlet and holley 390cfm carb, hurricane camshaft fitted in an MG B convertible.

I have heard that the cheapest option and good one is to fit a eaton M90 or M112 supercharger. This part is easy to buy on ebay, but what else do I need? Are there any existing brackets to fit? Can I mount the supercharger on the side so I don't have the carb sticking out the bonnet like a foot! Also, can I keep my carb configuration?

Thanks in advance for your help,

Gerrit

Thanks a lot for your answer. So I guess the only way to keep the holley carb set up is to have the supercharger in the middle, which will make it stick out the bonnet?

No no I could change the carbs. My other option would be to fit stage 2 head with hi rev valves.

I don't wanna make it unrealiable for only a few bhp more

The sprintex is probably the most logical one, but I enquired for the price in Australia where they are still making them and it was crazy.

I would be better off having the 5.2L RPI engine fitted.

I was just wondering if there was a cheap conversion like for the US V8 where you just put a S'charger in the V8.

Actually I don't care too much about having it go through the bonnet as long as I can still see where I'm going lol

Thanks for the link, great car! I think I'd better start with fitting the RV8 manifold, as the standard one which doesn't go through the wings is restrictive as of 200 bhp
