whats the best to have C/R at on High Reving N/A cars?

I've got 2.2 stroker on LnB Crank with Forged Pistons and Rods + T/B's lot's more spec but you get the idea.

What would you expect the C/R to be on this build?

Thanks in advance, Kev.

You want it as high as you can get it depending on whatever fuel you choose to run! On pump fuel i'd start at 12:1 and go up until you reach the limit of the fuel!

Will most likely be fine.. Possibly even on 98RON. Whoever maps your engine will be able to give you a better indication!
