This is the TMAXX one


Wonder if it would make any difference.

They make them for all size engines.

I had at one point read that you don't want the heat to disipate from the crankshaft too quickly because the heat helps with the atomization of the fuel which intern causes it to burn easier which would make these a bad thing.

If it was that big a deal the manufacturers would be installing them. And I have seen some kits that come stock with them.

It's probably one of those things that looks nice but I doubt your going to notice any diffrence.

I have sheard similar things, that you don't want the lower portion of th eengine to be cooled differently than the top, as well, there is only a small contact point for heat to transfer. They do look nice (bling bling), but I am not sure on the funtionality vs cost...

I have added heat sink motor mounts in the past when I thought it would help with an existing heat problem. Nearly all the heat is generated at or near the glow plug and exhaust port so drawing heat down and allowing a more even temperature throughout the engine can have benefits. I have seen my engine tempertures soar 20-30 deg. when I've experimented with graphite(non heat conductive) chassis. Forced me to richen engine and naturally I lost some performance.
Then again....there is the *bling bling* factor of CNC billet could something that looks soooo sweet be bad?
To finish first....first ya gotta finish!
