2N rearend...how stong is it?

Don't bother trying to run bare cylinder for increased displacement and more power. You're power limited by both the intake manifold and the low compression of a flathead engine.

BUT heres a trick to think about. SUPERCHARGE ITT!!! with a smog pump from a bigblock Chevy Truck. They are very efficent and designed for 8 liter V-8 and your little N-Engine is just 2 liters. And used ones can be very inexpensive at the used parts emporiums. The carb can flow enough fuel with its adjustable main jet.

There are a lotta hotroding books with excellent chapters on how-to supercharge. Usually, they are talking about the big Roots meshed rotor 2-cycle GMC diesel superchargers being modified for drag racing. But the basic principles are the same.

I am very serious about using a large V-8 smogpump for a pulley belt driven supercharger. But I ain't gonna design it for you, you're on your own with the idea.

I got the idea about 4 yrs ago from an article by Steven A. Richmond, "Dirt Cheep Supercharger". Do a Web Search. I copied the article but didn't get any addresses. Sorry.

Matter of fact, I think the N-Carb would lend itself very well because of the adjustable mainjet and there is no vacuum chokes or vacuum ignition advances to worry about. Just be aware, the N-Oilpump is not the greatest and can cause mechanical failure. Remember the dusty, dirty working conditions of the tractor, you'll have to come up with a good BIG airfilter.

I worry about releasing this idea to the N-Fraternity, because there are so many that can't even do a simple 12 volt bolt-on conversion from a kit. And NO, I don't know of any supercharger kits for N's ..... ..... .the huffin' & puffin' Dell

Ya, us simple minded tractor folks sure is lucky to have someone as smart as you watch'n over us, would'nt want one of your flock putting antifreeze in the gas tank or gear lube in the radiator !
