anyone have any Std hi comp pistons ?
« on: 05.01. 2020 22:20 »
I'm just about to fit some +80 gandini's to my race engine (the highest comp I could find) but the compression is a bit low at 8.25 so I'm starting to think I may resleeve the bores and a set of high comp's might encourage me.
I'd love a set of high comp +80's but something from 10.5 to 14:1 in standard would be nice (methanol engine).

I have some 14:1 +20 but a shame to skip a std size.

If you think, everything is under control, you are not fast enought.

Klaus,
 yes did see those, wasnt convinced they're 10.5 but must be close. Might need to buy them anyway...
Cheers

I'm going to stick with +80's for the time being!
