ianmcintoshi Posted April 2, 2012 Share Posted April 2, 2012 Hey My V runs 0.9bar but over the past few days it has been creeping to 1.2 and the other day it spiked all the way to 1.5... shat myself to say the least, my profec b was going tits at me flashing red and beeping lol. I run an external wastegate and nothing seems to have changed and its never done this before anyone any ideas? Quote Link to post Share on other sites
lilryan Posted April 2, 2012 Share Posted April 2, 2012 check all your vacume and boost pipes mate anywiring plugs aswell and check all hose clamps maybe breathing ect air from some where i had a vxr in work the other day doing same thing Quote Link to post Share on other sites
ianmcintoshi Posted April 2, 2012 Author Share Posted April 2, 2012 Checked all that yesterday mate and all seemed fine. Im may have missed something but im pretty sure thats not the problem. Thanks for the reply Is there anything else that may cause this? Quote Link to post Share on other sites

rorenapier Posted April 2, 2012 Share Posted April 2, 2012 Boost solenoid could be seizing up a bit.Pop the hoses off and poke some WD40 into it. See if that helps. Quote Link to post Share on other sites
ianmcintoshi Posted April 3, 2012 Author Share Posted April 3, 2012 Hmm will give that a go, the thing is it holds boost totally fine on low boost... wierd :S Quote Link to post Share on other sites
lilryan Posted April 3, 2012 Share Posted April 3, 2012 ummm drop your de-cat off and check the waste gate penny if your still running the internal waste gate mate as that vrx i did the other day when i booted it down the road the waste gate penny kept sticking open .all did was drop the de-cat spray some wd40 took the actuator arm off and worked the penny open and shut for few min till it felt looser put it all back together and was fine mate .so worth a look mate its normaly somthing silly like that bud Quote Link to post Share on other sites
ianmcintoshi Posted April 3, 2012 Author Share Posted April 3, 2012 Its external mate and the internal wastegate was welded up real good. It will most likely be something stupid... its is puzzling me at the moment tho. Quote Link to post Share on other sites
lilryan Posted April 3, 2012 Share Posted April 3, 2012 ummm id just go threw everything boost related ect checking all gaskets clamps sensors ect mate as you say its bound to be somthing daft it normalt always is Quote Link to post Share on other sites
Flaminsam Posted April 3, 2012 Share Posted April 3, 2012 your running the solenoid to the top of the wastegate yes? if the solenoid wasnt opening then you would only boost to the spring pressure in the wastegate (somewhere around 0.5bar), sounds to me like the solenoid is stuck open allowing the top of the wastegate to precharge the springs giving you higher boost levels.
