50 MM BLOW OFF VALVE
1.This BOV use the same spring, the spring is a bit more compressed in the BJRBT02565, which is why the spring rating is one PSI higher
2.The supercharge spring is specifically for supercharged car only; if you have a quick spooling turbo
it can actually push the valve open briefly before the charge gets to the mainfold,dumping boost
3. BOV's need a 1/4" innner diameter DIRECT source to the mainfold; smaller lines can cause delays in response time
SPRING PRESSURE HAS TO NOTHING TO DO WITH BOOST,ONLY VACCUM
