Snowman, is that Tom’s exhaust manifold? I’m seriously struggling on whether to pull the lane 350 from my 55 Belair and replace it with a built 250 w turbo @ 15psi!
Mick - the Mazda Millenia used an air to liquid intercooler under the supercharger... I would think you could do a draw through supercharger and force the pressurized mixturethrough the cooling fins without an issue. But, IMHO, I’d be going with meth injection. Nowhere as reliable, but far less complicated!
I believe it is. I bought mine off of ebay. It's the new design SPA 250 Turbo manifold. The link from Tom's website is below. Mine is the bottom with the wastegate under the center (new version) rather than the old one with the wastegate on the bottom of one of the exhaust runners (old version).
69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
