    Supercharging a Rover V8

    Questions to those who have done this and to those who know of one.

    I am thinking of a Street Toy, not a LR, but a Vitesse or sim SD1 Rover....

    Rover 3.5 or 3.9 V8 as the base model....

    So what Blower has been used?
    Pulley size? Belt size?
    Manifold? What did you get?
    Carb or injection?
    Mounting it?
    bonnet clearance in a Rangie / Disco? Was there a problem?
    What boost were you running?
    Est HP?
    How did you Decompress the Engine to run the Blower????

    So many questions, Not enough answers....
    Ritters wont tell me, just charge......

    Dont have any experience of supercharged rovers but i did own a professionally converted TR7 which had a 3.9 pushing out just about 300 bhp/300lbs per ft. (I have pics if you're interested).The engine was put together by John Eales (now JE Engineering) Awesome fun. It was done a good few years ago now but had forged pistons, nimonic valves, fast road cam, uprated oil pump, balanced and blueprinted, holley 390cfm carb i believe it had an extra metering body. The edelbrock 500 is a better choice nowadays apparently. But i reckon the four twin choke dellortos i saw on a Morgan in JEs workshop would be more fun
    Not sure what your reasoning is for a supercharger or the power you had in mind but there is a lot you can do with them if your not dead set on the blower.

    Put a Gen 4 6l in it, seriously, still alloy and you'll get close to flat 12's if you can get traction with a decent exhaust, tune and a lighter car, and cost less or similar

    Not going to happen, This car is all about making a Rover go, not putting a Gen 3 in it.
    Everyone puts gen 3's in there cars.

    I thought you might be able to answer some of my questions as you claim to have a supercharged rangie.

    You wont make the horsepower your after with an Eaton M90

    You need to use a centrifugal blower and intercooler, low comp motors will be fine, just the heads are ****

    The Janspeed twin turbo set up was on a 3619cc engine, it put out somewhere over 500 bhp and was clocked at 201 mph. Not too reliable back then and lack of funding didnt help. Have seen a 450 bhp set up also with twin turbos.
