Would you consider enlargening the ports on a rotary motor the piston equivalent of cam/camshaft upgrades?

They both change the lift and duration of the intake/exhaust stroke.

Only thing with a rotary is it requires engine disassembly which means usually waiting for a rebuild.

I believe it's the basic equivalent to a camshaft upgrade, but I've been noticing a lot of people who refer to ported rotary motors as "upgraded" motors when they're really not.

 

I would probably agree.. since all the stupid rednecks think my really big street ported motor has a really big race cam.

 

I do agree on the first part but i do think ported motors would be condidered "upgraded" or "modified", because is that wasnt true they would have to be stock and thats not the case.

Yeah I get that alot too! "Dude that cars camming"

Gets my laughing everytime!

Based on the way you explain it I agree that it is similar. But I also consider it an engine modification since cams can be changed back to stock where a ported motor will forever be a ported motor.

(Then again if you warp your housings and have the motor rebuilt I guess its back to stock. Hmm... o well)

 

I guess porting the rotary would pretty much be the equivalent of porting the heads and adding high lift cams in a piston engine. Its just one job to do them both for us.
