What Compression Ratio do you want the Probe Forgings to be?

[Doward]

Answer above please.

I vote 8.5 This is right around stock, and I think a very good compromise between off boost response, and on boost maximum power.

Just want to be sure everyone agrees with my thinking

da-bump.

:werd: on the 8.5, I'll be getting a slight overbore anyways, so it should be higher by a bit. I'm not too keen on having something closer to an NA stock comp.

Ya...I want it to have less chance of detonation but not drive like ass off boost. Stock compression (or close enough) works for me.

Actually, looking at the piston/head setup, I think we're going to see a little improvement in the quench area - this may raise the compression slightly... waiting on Shawn to get back in touch with me regarding this
