Has anyone tried to put turbocharger on a flathead? I was thinking the negative would be the addational heat build up because of how the exhaust goes around the cylinders. The way around this might be to get a cam that would change the intake to the exhause and the exhaust to the intake. Ahyone have heard about this?

Well, you're definitely "thinking"! There have been some examples in the past, but the "water-cooled" exhaust takes energy away from the turbo, and uses it to heat the coolant instead. As for your idea of reversing the intakes and exhausts, that was pioneered in the 50's in SoCal with a drag coupe called the "Switcheroo". They ran 6-sidedraft carbs on the sides of the block with the exhausts exiting straight up through the hood. The problem with this for a road application is that now you have a water-heated intake! The Switcheroo got around this by having the block filled with waterglass, as it was only running a quarter mile on methanol. Had this been a really good idea, others would have followed, but to my knowledge none did. I suspect the long, torturous intake tracts negated any exhaust efficiency advantages. If you want to see an extreme example of a blown Ford flathead, check out the 300 mph motor in Ron Main's "Flatfire" record-setting Bonneville streamliner.

Thank you. We are always happy to contribute. When I bought my first collector car, the seller gave me a dog eared catalog for a vendor that is long gone. Being able to know what you need, and where to get it, is essential to enjoying our hobby. As for turbocharging a flathead, two things come to mind. The slow turning engines likely wouldn't produce adequate exhaust to spin the turbo enough to do a good boost, and if it did, the pistons would be damaged. I have a turbo engine piston on my desk that is a vivid example of what happens when the combustion exceeds the ability of the cooling system to carry away the additional heat load.

Windjamer: Check out the May 2012 issue of Hot Rod Magazine. There are some very well-researched recommendations regarding turbo sizing for Flathead Fords.

Yes, I think someone did make a reasonably serious effort to design and install turbocharger set-ups on flathead Ford V-8 engines. Attached is a photo of two exhaust manifolds which turned up at the flea market last August in Auburn Indiana at the EFV8 National Meet. I doubt that they were home-made. These are pretty complex castings which appear to have been intended to push exhaust gases up the first bolt-on tube, and then exit downward through the second bolt-on tube, after having gone through whatever was mounted on top of the tubes. Does anyone recognize the application, or remember ever having seen such a set-up ? Military ? Agricultural ? Industrial ? Aviation ? Big truck ? Hot rod ?
