What's a better option? 9.5:1? I don't want to go all the way down to 8.6:1, then I'm just running more boost for the same power level. That is why I chose 11:1, I know combustion temps can get very high but there's ways to work around that, WMI for instance.
Edit: I'm asking because I can change the order before it ships.
Aren't these the same thing?

Here is your 11:1 with turbo build that all the naysayers in this thread are drooling over.

We're just haters, though.

no one said that 11:1 pistons cant ever be used.
OP said he will primarily run the car on 93 gas, with maybe some e85 here and there. in which case 11:1 pistons is not the correct choice.

I'm going to recommend you do some reading on internal combustion engine design and theory of operation before making recommendations to the other noobs. Study things like rod ratio, undersquare versus oversquare engine designs, quench, tumble and swirl, combustion chamber design, the effects of cam duration and overlap on dynamic compression ratio, and definitely forced induction detonation characteristics relating to mechanical compression ratios. Report back your findings for us.

All engines must have identical design properties in your world. Why doesn't my Miata make power at 14,000 rpm reliably like my motorcycle did? Surely they are both engines! Maybe I am just a fool for not trying to rev my Miata so high. I haven't tried it and it just might work.

Oh it is, baby. Rock hard.
How about maybe just the difference between static compression ratio and dynamic compression ratio?
It would be nice but it's not necessary if 208 learns anything or not as long as he's not spouting antithetical bullshit to trusting and unsuspecting noobs.
