10:7:1 CR high for boost?

Hey All,

I drive a Albaster White 2006 C350 sport package with minor mods (not engine). Mods include: VOLK Progrssive ME (19" 8.5, 9.5). Front CF Lip, CF wing (I haven't put on yet), HID (not BiX) and Remus exhaust (soon to come vinyl roof).

My question is:

Is 10:7:1 Compression Ratio high for 6psi boost? My engine is a M272 35.

What do you guys think? I have seen a boosted c36 which I believe runs 10:5:1 CR. I don't know about 10:7 though.

Thanks

That is way too high for 6 psi. Even 10.5 is way too high. Imo you need to drop it about 2 full points if you expect the engine to live. :)
