ahhh, the norton... you gotta have ***** to air-cool a rotary :p

 

That is F-ing awesome, man! I wonder if anyone has pics of the suzuki re5 (i think that was what it was called) motor? Those are such cute little rotors...

 

how fast does that norton motor spin?

 

Im not 100% sure as the rest of the bike is in a different town, its not particuarly high possibly 7-8k it has a really linear power delivery as well. For the capacity the rotor width is significantly wider than either of the mazda engines. There are no oil control rings and the rotors run on needle rollers. It uses an omp similar to the mazda one to inject 2st oil onto the eshaft and housings there is no other oil lubrication its basicly the same as any two stroke engine. The inlet air is sucked through the rotors for cooling, there is an SU carb on each housing with the throttle butterfly right in the inlet port of the housing.

 

neat.

let's port it!

 

I might tidy up the castings a bit but the best way to get power out of it is to modify the rotor cooling so the inlet air doesnt get heated. I think norton used something like a pressure wave supercharger, exhaust pulses to move air and use that to supply cooling air for the rotors, chuck on a set of flat slide carbs or maybe efi and it should be good for about 130 bhp

 

I'd bet it has a lot to do with the poor heat transfer characteristics between two metals sandwiched against each other, as compared to if it was just one contiguous chunk. The sawblading gives a lot more surface area between the steel and the aluminum.

There's a damned good reason why a lot of sleeved piston engines had "wet" sleeves that were directly exposed to the coolant, despite all of the problems associated with wet sleeving. (AHEM Cadillac 4.1/4.5/4.9l ...)

 

have you seen the sleeves from the northstar engine? PIMP

 

Alright,,, whos the fool that called me a moron?
