Default RE: what compression?

So your saying I cant have a nice engine built and wait until later to add some kind of boost to it? That would be pretty stupid. Changing a few things to make it run right if that I ever decided to go that route would make no difference to me. This is my first major build of this kind so I would rather just spend the extra cash now to get quality stuff and not have it all break apart the minute i get on it. This is my reason for being on this website to do some research and ask some of you guys that might know a thing or two about this stuff. And I got my money back from Woody because of personal reasons. I would rather use Eagle products after speaking with folks and doing research of their parts

well you could always run high comp now, and if down the road you decide to boost it, switch over to some lower comp pistons. That would only hit ya what like 600$ down the road? I'm not really sure what a good set of pistons cost?

If you want boost later you'll want lower compression now, with lower compression now you'll want a smaller cam to run it n/a and power will suffer. With engines you can't have your cake and eat it too. You could build a higher compression n/a engine now and then add nitrous, nitrous likes higher compression, but boost likes lower compression.

What is pretty stupid is your failure to understand the differences in building a N/A motor vs a boosted motor..with about 9 to 1 which is what stock stangs come with from the factory I've seen people on here running 12 psi with a decent tune.......but if you build a flat top piston stroker and let ssay 58 cc or 61 cc heads to top it off you'll be around 10 to 10.5 to 1 and that's to much for a boosted motor you'll pop head gaskets left and right and break and burn stuff up.....and the changing a few stuff in the future would be pistons....no little stuff IMO!! so quit being so bullheaded and listen.......[&:][sm=chairshot.gif][sm=headbang.gif] build it right and do it once ........if you wanna run 12 psi and above in the future design the motor to have 8.5 to 8.7 to 1 compression......now if you build a stroker with flat top piston and 10 to 1 comp....add that to the pressure the boost generates in the cylinders and your static compression will be through the roof!!!....so read this link and pay particular attention to the section on compression ratio/ boost pressure....high compression = small amount of boost you can run
