Hey guys im new to the forum rhat being said im trying to put together a bottom end that will hold 800+hp no problems ....question is what will -4cc pistons with .927 wrist pin height due to my compression im also gonna be running turbo and do want to get lower than 10.5.1 compression so i can run e85 as daily

 

what exactly is the question?

 

My brain hurts O.o


But seriously, to calculate your compression ratio we would actually have to know about your engine. Is it currently stock? Are you going to run stock heads with your turbo or aftermarket?

There are plenty of CR calculators online as well.

 

Im lost.... elaborate more plz

 

You need to provide more info for anyone to help figure out your compression ratio. Here is a link to an online calculator where you can see what information is required and see for yourself what you need to get it where you want it.
