    Default Supercharging a 75 V8

    Quick question chaps, as I've been lurking for a while!

    Has anyone ever fitted a Supercharger to a 75 V8, as I was under the impression that the gearbox was marginal for the increase in Torque?

    Any comments most welcome!

    Hi and welcome.

    I would guess there would be all sorts of mapping issues as well.

    Fitting the S/C is the easy part. Getting the mapping right for the Autobox ECU may prove difficult.
    Having said that, everything is possible with the right amount of money.

    Thanks for the prompt replies guys!

    So for all intents and purposes then, it's a non-starter then!

    Looks like a ZT then!

    my personal opinion, and I am no expert, sure someone may be able to coble one togther, but unless the mapping is 100% spot on, would it last long? I very much doubt it. I believe Dreadnought spent a lot of time and effort ensuring that their mapping was correct

    You could go for a supercharged ZT and convert the internal trim and kit from a R75.

    No, I prefer the ZT to the 75 anyway, it just came up in the Thread on the other site, over that 75 V8 that's For Sale after the guy died and it was mentioned that the 75 could be Supercharged and I didn't think that the autobox was strong enough to take the extra torque!

    Is it that same as used in the same era Mustang then?

    Ah, that one that's on ebay as well. The box can probably take it but the problem is that there is no proper map available for the autobox.

    Surely the auto box map is simple, just use 5th, everywhere...

    Its about all I do with mine now. Sounds like a big-block v8 down around 500rpm!
