What are the consequences of running 10:1 with a supercharger?
I'm here to learn. What would be the consequences of running forged 10:1 pistons with a supercharger? Maybe 2.8 pulley? Meth is probably a must? Is it even worth doing that vs just buying 8.9:1 pistons? They both cost the same. Is this just a block explosion waiting to happen?
FWIW I've got nothing in my hands. I'm in development right now.

I wonder if the block feature blocks people from posting in your threads...
I'm used to old motors when it comes to forced induction. I'd always been taught to go low compression with forced induction, but I realize now it's probably because it is way more crude to control on an old engine with a distributor and carb.

So, not a pioneer but more of an idiot? I mean, you have the facts, your **** breaks at point X yet you pretend the rules don't apply and go past it? Pretty stupid. I know a Honda civic that has 720hp, and it lasted a week. Jussayin

Wow. Just wow.
To answer the OP's question; there are no consequences. The reason lower compression numbers go with boost is to reduce the chances of detonation and to lower combustion temps. The higher comp will net you more power, but you will need to tune for it like anything. If you drop the compression to low you will have to feed your motor more PSI to generate power, but on the flip side if you go with too high of a comp ratio you will have a bad time tuning the thing on pump gas with boost. Personally, I would go with the 10.0:1 and tune for it. More power per psi of boost, not that drastic of an increase, and as long as you tune it well it will be fine.

I suggest you use Google before opening your mouth. Seems to be something I've noticed you do far too often.

10:1 with a supercharger is considered "ideal". Superchargers take power to make power because they are belt driven. Higher compression helps to alleviate this loss in the low rpm's by increasing efficiency of combustion throughout the powerband. Like blackss said, you compensate for this with tuning and a reduction in timing to meet the engine requirements. I have seen as high as 11.5:1 on 93pump gas on supercharged car's. And I have personally run 11:1 on 8psi on 93pump gas. It all depends on the tune and the fuel.
