Cooling fly wheel.
I'm trying to improve cooling for my engine. Any one of you guys have an idea where I could find a cooling(vented) fly wheel for .21 engine.
Thanx

RE: Cooling fly wheel.
Vented flywheels cool the clutch bell, more than the engine (although they probably do cool the engine a little bit). Usually, they are a little lighter as well, which in theory provides slightly better engine response, but in reality they don't make a very big difference. If you're one of those people whose clutch bell gets discoloured from the heat, then it's probably worth doing, otherwise, probably not. It seems that the pros don't really bother with them. They are nice and bling tho'...

RE: Cooling fly wheel.
Contrary to popular belief you don't want to cool your engines crankcase too much. Things like a cooling flywheel, heat sink back plate and engine mounts can actually degrade engine performance. When fuel is atomized in the carb and flows into your engine, that mixture requires heat to remain properly atomized. If the block is too cool the engine will not run as efficiently. We all know what happens once you get the engine warmed up. Power goes through the roof! Overcooling the block will not get you there.
Many airplane guys use aluminum engine mounts but many of them insert wood spacers to isolate the engine from the mount for just the purpose of not overcooling the block. Vibration is taken care of with soft mounts to the fire wall if anyone was wondering.

RE: Cooling fly wheel.
my experience with vented flywheels has been the tend to force dirt into the front main bearing of the crankcase causing pre mature bearing wear and crank damage...i would not rreccomend them to anyone except mayby my competition

motopro hit the vented FW issue...I used em on my T-maxx but those sit higher off the ground........

RE: Cooling fly wheel.
You probley wont believe this but-----------Back in 1992 i invented the the cooling flywheel
---I started a company called cricket racing products--we made parts for alot of racers in offroad gas. I was the first to design the vented flywheel---the concept was great but the demand was not[
]--we also made titanum front braces for the rc10gt gas truck. Richard Saxton ran them on his truck win he won the us gas nationals at the ranch pit shop in cal. I have seen copies and variations of the cooling flywheel over the years in car action mag.
***note*** the flywheels dont provide a significant amount of cooloing but they are lighter.
good luck in your search.
