An interesting phenomenon I encountered when I put the BTTF build on the back of my car is how much cooler the engine ran while I was driving. When I built it I left the exhaust vents open to the engine cover vents. While in motion, I get a Bernoulli Effect across the top of the vents creating a vacuum at the back, thus sucking the hot air out of the engine compartment. > -----Original Message----- > From: B Benson [mailto:delornut@xxxx] > Sent: Thursday, June 26, 2003 3:17 PM > To: dmcnews@xxxxxxxxxxxxxxx > Subject: Re: [DML] Venting outside air over engine > > Intake air and coolant are the important items in maintaining proper > engine > temps.
