Re: [DML] Air intake performance

["cruznmd" <racuti1@xxxx>]

I hear this a lot, regarding the mixture valve. I haven't driven my D 
yet enough to know either way, but I have an idea about another 
complaint that I've heard a lot of...

Most people I talk to say the PRV runs hot. Most say they'd like them 
to run cooler or have better airflow in the engine compartment.
Isn't there a way to turn at least that passenger side breather gill 
for the hot/cold air mixture valve into some kind of vent that washes 
air over the engine? Perhaps some kind of duct, or maybe even a small 
electric fan with a diverter?

I realize the engine doesn't see much air movement being mounted in 
the rear, but at least the cover is well ventilated, and it has a lot 
of room around it (relatively speaking). I'm suprised to hear folks 
say it runs so hot.

Also, for those who are interested, I've finally got all my 
transmission brackets, clutch lines and pieces all hooked up. I can 
finally get back to the engine/head work (and work standing up, thank 
God) I hope to crank it over during the first week of July.

Ever work on a car so hard, when you're done you're afraid to start 
it up?
