Okay my RHB5 is boosting 10psi mostly and every once and awhile it'll go to 11psi, how could this be without any type of boost controller? stock actuated at 8 psi. could it be cuz i got my HEAT SINK under my hood? (DSM SMIC where the battery used to go..) let me know what you guys think..

my block should be able to handle it for a while D16A6 bottom end has ~65k on it.. its been holding, thats all that counts.. i'm running rich also so i don't detonate.. also.... 10 psi rules!

 

maybe you have a kink in your wg thats not making it open far enough to hold 8 lbs. or your line could be pinched from vac. to ur wg.

 

your wastegate isn't hooked up right

 

I hit 9 on my rbh5, so somethigns not right in your setup. Oh yeah, your boost gauge could also be reading wrong. My autometer sucks, i go by my vafc. The boost gauge will read higher than it really is, so technically, you coul dbe at 8. I hit 9 and it sticks there.

 

my stock actuated probe ihi only went to 6 psi

 

you guys were right.. the vacuum line from the WG to the turbo was pinched off cuz i put the filter on the compressor housing and that made the vacuum line tight... put in a new vacuum line and i'm boosting 8 psi now.
