I hear you on the feature creep. I'm interested in a small turbo system, for a stock engine pushing through a stock carb. Just 6 psi of boost through a small turbo sized for a stock engine that won't be taken over 4500 rpm. In 5 posts the discussion will be a 15 pound system and making "real" power! Even the small system will make more power than any carb swap on a stock engine... I think?

Yes. A carb, cam and exhaust change could net you maybe a 10% increase at the top of the rpm scale with probably a loss at the low end. A property sized turbo will get you a 50% or more increase throughout the rpm range with no loss on the bottom end.

This is a simple turbo kit on the cheap. You'd likely need a few more bits to make it work. But it's a starting point, turbo included in the kit.

IMO, a supercharger? The juice is not worth the squeeze. It takes power to rotate a supercharger.
A turbo is, IMO, free boost. It get's it's spin from exhaust gasses being released from the engine anyway!

On a single carb manifold I would think one that has excellent thermal conductive aluminum warmed up right under the carb like that Low Profile Manifold would, be best. Not sure what to do to connect it on a single port engine though?

I wonder if you were to tap the passage and run oil from the motor through it if it would heat the manifold once the oil came up to temp?

That link seems to be without the turbo but I do believe they supply a kit with it as well.
Superchargers do work but are not as popular these days with both the hobby crowd and the manufacturers of autos. The turbo is really the king these days for it's simplicity.

Yes you could but remember it would take ALL of the oil to get enough heat volume, you would max out around 200*F compared to 400+*F and it would take 20 minutes to get that temperature on a cool day when you need it the most. The exhaust is hot in a couple minutes.

"earthquake" You might be on to something, Probably could replace the need for an external oil cooler in a hot climate!
