Whats the difference between the greddy type r s and rs? and also whats the difference between the realy greaddy ones and the knock-off? im only gonna be runnin about 7-9 psi so which would be best?

 

type r is made for higher boost/power applications. Stick with the type s or rs.

 

Get a Greddy Type S. That's what I have. I'm only running 7psi but plan to turn it up to 9psi in the near future. Works great for me

 

how much psi can the type s hold???

 

i run 15 pounds on my type s, and have for over a year. and i know of guys running quite a bit more, a couple run like 21 lbs and maybe more. im sure itd be fine for what most what most people are going to run.

 

is the type rs better or is the type s better??? which one in your opinion sounds better if there is a difference in them

 

i dont know much about the rs, but i think the s is one of the best sounding BOV's. im not sure of a sound difference though.
