procharger filter mod
#23
well i went out to test it and for some reason my big red bypass valve was coming open in higher rpms so my boost level was leveling out . so i checked for a vacuum leak and couldnt find one so then i did a boost leak test and found my valve was leaking from the under side where the shaft comes out. so i pulled big red off and took it apart and found that the diaphragm was blown out and cracked . so i called procharger today and ordered another one hopefully that is my problem. what was weird is i was logging with hp tuners and it showed me @3200 rpms at 15.2 psi and would just flat line through the rpm range at that which i know isnt true its just impossible at that rpm, and my boost gauge was reading 4 psi and wouldnt go above that. hopefully the bov is my problem i will report back after i get the new gasket in.

So if I understand this correctly, you basically take off the Red K&N filter and put a some doorscreen over the opening and clamp it down? I am game to try it on my P1 to see if there is a gain or not.

well that was my problem truck is healthy again. so did a couple pulls with the filter , with the screen and with nothing on it.so going from filter to screen you can feel a big power difference and see almost a 2 psi difference so i took the screen off and boost gauge is having a hard time at the top of first reading steady i think the belt is slipping lol top of second still seeing about a 2 psi gain over the filter but gauge was haveing trouble staying steady think because of belt slip also. looks like its time for a 8 rib and a 10%OD crank pulley . conclusion remove filter for more boost/power!!
