Re: EM JetHot Coatings

[Stephen Williams <mannlaw@indy.net>]

	I mentioned louver's here awhile back because they really are
effective in scavenging heat.  Remember though, to really make louvers
work well you have to plan on getting air into the engine compartment from
front of car while driving [thus getting a "forced" deployment as opposed
to a "hot air rises" sort of passive deployment of heat].  Works really
well if you think it through.  Some of the new vents on other cars work
well too.

	Look into shielding the turbo / compartment with a blanket.  Lot
of Buick GN's that race take this approach.  
	
	Many other ideas at work on cooling, but out of time right now.
