Hot car, hot humid day, performance problem
I was out Woodward last night in my 80. The day was about 85* and humid. My car has a 180 t-stat and a lighter weight fan (not a clutch fan).
I sat idling waiting at the drive-thru for food for about 3-5 minutes. As I took off, I tried to accelerate. After about 2000 rpms, the car started chugging and sputtering (almost like if you try to drive with your choke shut). I could see fuel boiling in my fuel filter when I finally parked a few mins afterwards. I have a 10" Chrome air cleaner on the car with an open shaker scoop mounted to the hood. No heater/ac. Car has a 68 400 with 69 #62 heads. Again, 180* Thermostat. What would be my best course of action to prevent this from happening? Aluminum radiator to dissipate heat (such as a BeCool)? Electric fuel pump acting as a pusher for more liquid fuel (presuming that my fuel was turning into vapor when the issue occurred)? An electric fan in conjunction w/my current fan? (If so, what cfm/size is recommended?)

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs.
