nsta Posted January 8, 2006 Share Posted January 8, 2006 Hey guys, my r33 shows a little under halfway mark on the factory guage, around +3 (~ 6psi???) when at peak boost, and never once gets any higher, as i have an exhaust and pod, i would think it'd go higher than this, at least factory spec. My mate recently tried doing the high boost mode solenoid trick, and played around with some of the solenoid hoses, could he have screwed something up in this area, ive attached a pic, though i think he may have the top and bottom hoses mixed up on the solenoid, can someone please confirm. Also we recently tried fitting a boost tap to my car, to no avail, could someone, pleae edit my picture and show me how to fit it correctly, using mspaint or something. thanks in advice Link to comment https://www.sau.com.au/forums/topic/101169-my-r33-is-running-less-than-stock-boost/ Share on other sites More sharing options...
igor Posted January 8, 2006 Share Posted January 8, 2006 It looks to me that the actuator hose (bottom on the solenoid) is a tad long. Try making it shorter.

nsta Posted January 9, 2006 Author Share Posted January 9, 2006 will making it shorter help, if so how? Link to comment https://www.sau.com.au/forums/topic/101169-my-r33-is-running-less-than-stock-boost/#findComment-1847246 Share on other sites More sharing options...
igor Posted January 9, 2006 Share Posted January 9, 2006 Making your vacuum hoses as short as possible is a general requirement for any sort of boost controller. Long hoses cause lag in boost response and inaccurate boost pressure. It could also be your boost gauge. Get a cheapo analogue gauge and test with that.

NICKS33 Posted January 9, 2006 Share Posted January 9, 2006 the factory guage isnt in psi...so on stock boost it only goes to about half way in the positive side...even doing the boost trick it doesnt go much higher on the stock guage...u need an aftermarket guage to accuratly know what its doing....by the way in doing the boost trick ur cutting the black wire and putting it to the chassis yes? because in that thread there was a bit of confusion about which wire it was...ive done this to my car and it is the BLACK waire that needs to be grounded...

paulr33 Posted January 9, 2006 Share Posted January 9, 2006 the boost is fine, the guage you reading is in mmhg. +700 mmhg is 1bar so your running around 350mmhg which is aroud 7psi. its fine Link to comment https://www.sau.com.au/forums/topic/101169-my-r33-is-running-less-than-stock-boost/#findComment-1847495 Share on other sites More sharing options...

race_snooze Posted January 9, 2006 Share Posted January 9, 2006 Not sure if this will help, but just recently i lost a couple of pounds due to one of the very small hoses of the intake, repaired and now fine. So also check for broken vac/boost hoses.

nsta Posted January 9, 2006 Author Share Posted January 9, 2006 (edited) i did by some new vac hoses for the solenoid to factory t-peice, but its not broken, and definitely tight, i just cut the hoses for a tight fit, so its not lenghty anymore........does it matter if the hoses are on either top or bottom of the solenoid?, as it seems to not make much difference when i drive! havent tested the car yet though i will soon, can anyone tell me how to fit the boost tap to my car...
