The heat 'issue' isn't new, or excessive. At the first show I attended with the new motor, I overheated waiting in line. I cn't remember exactly how long the wait was, probably over 20 mins, just creeping one car length every couple mins. When I got in and turned off, I popped a hose. Bottom line, even on a moderate temp day, she will overheat sitting still, no question. Ergo the bigger fan. NO room for a shroud.
It's just a lingering issue that I finally addressed.

Chas, I understand trying out a 30A fuse on the puller and see if it blows, but I'm not clear on your suggestion for the pushers?
