sux that another one blew up...

 

I just want to know what the benefit would be if I went with a higher compression ratio or a lower one? Can anyone explain what I should go with and what are the positives and negatives of going higher or lower.

 

the higher compression often leaves little room to run more boost if that's your goal although this statement is not completely true in most cases..

If you plan on building stronger and want to keep boosting higher levels keep the stock compression ratio but go for stronger rods and pistons..

 

I'm not 100% sure but isn't it the opposite? With higher compression wouldn't you want to run lower boost?

 

i've seen some crazy **** over the years where people use a 10:x:x /11:x:x ratio and boost the **** out of it and no problems while others depending on car/motor cannot run more then 5-10PSI on higher compression.

General rule of thumb is to keep stock compression on factory boosted cars but find ways to strengthen without comprimsing performance and motor.

 

You can still run more boost, you just have to do the engine right.

What I think he was trying to say is that there is little room for error.

Generally higher compression = more power, but also = more stress on engine.

 

Ok I think I am just going to go with MAHLE forged pistons in either their 8.5:1 or stock which is 9.5:1. I do not want to go up in compression because I already run 20+ psi on the blower and will soon be going to HAHN for an All turbo kit for 20+ psi!
