Anyone know anything about turbocharging a carburetor setup?

Sorry this is non SC related, but I'm excited. Got a new project for my brothers truck on my hands.

HP here in NM makes carb kits I believe. You have to build a "box" with an inlet to enclose the carburator. You can go to Paxtons website to see what I mean. I'll try to find some pics.

Here is one example even though this is supercharged. Same idea. Nice huh. :D Notice the carb box, it is cutaway in this pic so you can see the carb.

Thanks for the pic. The idea behind that is to pressurize the whole carburetor. This is to prevent boost from blowing gas/air out of the carb seals.

You can find loads of good info on turbocharging with a carb here. Read all you can before asking questions, or they will just tell you to use the search button.

Yeah...I read post and FAQs for at least three weeks (doing research on the 347 turbo SC) before asking anything.

Thanks Dave. I thought the turbomustangs.com forums would all have been for EFI setups, that's why I've skipped over it. Thanks for the info!

Are those just the stock exhaust manifolds with a flange welded on the one for the turbo, and the other manifold is attached by a cross-over pipe?

One is a stock manifold, the other is a custom piece. It has the ports lower on the body of it so the air flows upward towards the turbo. The crossover feeds into the bottom of the turbo manifold.

You can modify a HP series Holley following the instructions here:

Or order a carb built for it from Quickfuel

You can use these carb hats up to at least 15 lbs of boost if the carb has been modified as above:

You will need special floats. My dad and uncle turbocharged a 1967 GTO with tri-power in the late 70's. The turbo would crush the floats. They they found cork filled ones that did the trick.
