underhood supercharger?

i have a 70 corvette with 454" engine. I am curious if anyone has put one of the vortech, powerdyne,...etc. type supercharger on their car? will they clear the stock hood? have they had any heat issues?
thanks for any input

Woobie, you must not have looked in your engine compartment any time recently - there is simply no room to install a centrifugal under the stock hood. There is someone on the forum that has a '66(?) big block with a centrifugal. He simply cut out the hood where the centrifugal and the pipe/carb hat interfered. Sounds goofy, but I liked the way it looked. Post in the C2 forum area and you'll probably find him.

I think he sold that car, I'm not 100% on that though.

There was a guy with C3 that had a centrifugal mounted under his hood. He posted a picture of it. I haven't seen him on here since then. He made special brackets for it, and I think he did the fabrication. You might try doing a search in the archives.

Re: underhood supercharger? (81vette)

Now how about that, not one but TWO small block C3's with underhood centrifugals - nice. I still think an underhood centrifugal on a big block is out of the question.

As I read through those posts in the referenced links I did see something that needs to be corrected: carburators DO work wonderfully on a blow through setup, mine certainly has terrific power at every point in the powerband. A carburator used on a blow through setup is quite different than fo a n/a engine. The obvious is to boost reference the fuel pressure. The less obvious is that booster selection/design needs to match the intended boost levels. The Carb Shop, http://www.customcarbs.com , installed some custom drilled billet boosters in my carb (it has run as much as 17.1 psi peak manifold boost, and I am confident that it can handle more boost just fine).

Re: underhood supercharger? (woobie1966)

I'm interested in this too, but for a small block. Is a serpentine setup required assuming everything can be made to fit? The car is at the paint shop now, and I don't recall how the pulley system goes.
