Hypereutectics pistons and alcohol
Considering some KB hypers (64cc heads) for a production SBC 406 Alky setup. Plan is to run N/A alky 13:1 ratio 500-600hp with a rotating assembly rated for 650hp max. DRAG Car.
Its my first engine and after some research and deliberation I want to try alky over pump gas/NOS. Anyways, I really haven't found anything that warns against hypers & alky. I know hypers are not a good idea for NOS, supercharging etc. I've read plenty on the differences of hypers: harder and more brittle, less expansion, tighter clearances and timing.
Does anyone have any experience/knowledge on using alky with hyper pistons?
good, bad or ugly...
tks
