Just had this discussion on another board about making some kind of sealed intake system on my 502 mag(I don't want to cut up the sunpad!). Only two 16"x2" vents and my engine compartment seems to get very warm.Originally Posted by Raylar
It actually got started because I was asking about running an intercooler on a NA engine to keep the intake temps low. Most agreed that the cooler air would be offset by the airflow restrictions of the intercooler on a NA engine so the converstion turned to allowing the engine to suck fresh outside OUTSIDE air.
It was 95* here and very humid this weekend. I lost about 200 rpm and 2-3 mph when compared to a 75* day with lower humidity.
