Hey guys i'm running a greddy 18g turbo kit on a fully built 2.0 liter gsr..boosting 10.8 lbs making 300 whp...now as most of us know, the greddy kit is extremely conservative, being a street legal kit, someone had told me that since im making so much power on such a small kit with a small exhaust housing that it could be causing too much pressure to back up into the engine? does this make sense? i understand that this will without a doubt restrict power, but is it in anyway harmful to the motor?

Simple question. Simple answer. Yes. Search backpressure

powerloss = yes. i dont see anyway it could harm the engine tho

isolated hot pockets of nonburnable gasses in the combustion chamber creating uneven flame travel, potentially localized hot spots leading to pre-ignition. and just overall less power output from a non-homogeneous mixture in the combustion chamber

^^^ yes it can become harmful to the exhaust side of the head. Because the hot exhaust gases cannot escape fast enough

Poootie

say that 3 times fast! lol
