I was wondering to anyone that does how hot does it run? Do you have to let it cool down alot or hardley ever? I would get an Oil Cooler with the Piston I just want to make sure I wont have any problems. And any other info on the piston is a appreciated. Thanks

 

I had a 12:1 aries piston from alba

had about 3 seasons on it, held up well but had to run race fuel or octane booster to keep it from pinging. Best performance was on race fuel. Never got real hot or anything, didnt have a cooler.
