^ This is why I went with a Performer instead of an Air Gap.
And you live in Texas!!! Where the weather is borderline opposite of the N/E and Canada.
I remember talking to a guy I work with who is an old race mechanic and engine builder about the same problem with tunnel rams on the street.
Exactly the same issue. They'll work on a cold day, but not for street driving/cruising. It could be 40 degrees outside, but at 4000-9000 the tunnel ram will be fine. Who cruises at those RPM ranges? We, my son and I, build streetable rides so Air Gaps, tunnel rams are not in the equation - ever!
I'd love to have the time to build a strip only car, but that would be a brand new learning curve, and by the time I had it figured out I'd be in my 70's lol. Also, I should mention that I'm done with carburetor's due to the amount of additional time they take. I guess I should've gotten started in this hobby when I was younger. Oh well. FWIW, my present goal is to not have a car in the driveway that isn't forced induction. Fortuantely my wife is a Ford fan and her Fusion has a turbo 🙂
This is a nice, pleasant conversation though and I'd like to commend all of you for that.
