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.

Cheers

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