  Really?? Weird. Now I'm even more confused. :-) How can you seal
off the airbox with cowl induction? I was under the impression that
the back was just "open"... Dang... Now I *really* need to see some

up on your site, Robert!

  Yeah, the price is a major factor for me too... (That, performance, and
"daily driveability".)

  I guess that depends on what kind of race cars you're talking about...
Nascar uses cowl induction, drag racing seems to use both.
