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.
this is Exactly what I was going to post.....I use the wood shims in my buggy too....I was always running real lean bogging til I did that...man what a smooth throttle response that made....why do you want to cool your engine more??? are you running real hot all the time??? try different fuel w/ more oil before dropping coin on useless stuff
motopro hit the vented FW issue...I used em on my T-maxx but those sit higher off the ground........
