[QUOTE="djdilliodon!, post: 8775550, member: 684299"] the pole piece needs to be magnetic. As a coil heats up, of course the surrounding areas will heat up as well and it’s no secret that aluminum is excellent at shedding heat quickly. The thing is, does using a sleeve over a pole piece going to really affect the coils temperature to a significant degree? Is that aluminum sleeve going to affect that pole pieces magnetic strength? I think temp wise it won’t make a significant difference. In order to make a big difference in cooling of the coil, whatever you do has to directly concentrate on the coil itself. Porting would make the biggest difference and in a way that directs as much air as possible over the coil. That’s what I’ve always concentrated on and it works perfectly fine. [/QUOTE]
