That's not really a fair question, with E85 your water temp needs to be 170 when you stage, E85 turns to vapor at 172 degrees where gas turns to vapor at 68 degrees. We had some hot weather this summer over 100 one race day and I stage at 170 and come back to my pit and I was never over 185 and it cools back down to 170 within 5-7 minutes. When it's cool out you could run round robin as long as your tranny is up to it. Last weekend it was 70 degrees out and I staged at 170 and got back to the pits at 170
