12 to 1??

Depending on the timing and how high will you rev it, standard pressure should be good for road, 15/ 20min track day start to grind and loosing gears.

I run an ultralight on mine now whit orange diaphragm, 998 +40, 12g940, RE13, CR gears....

Put an engine together last year standard flywheel, lightened and balance, std pistons, 12g940, cooper 997 cam, damn that thing its fun, used blue diaphragm is holding strong even whit 13 wheels.
