Why is it wierd? a stock Sti should be around 0.9-1.1kpa/bar @ 4000rpm.STIprdr said:Hey guys I was wondering if any of you installed a boost gauge in an EU STI and what kind of boost are you reading and maybe with what mods? Because I'm thiniking I'm reading something a bit wierd with my boost bauge! Thank you very much for your help!
Sounds like u'r running with the stock boost-solenoide valve? The stock solenoide is somewhat unstabile, and that is most likely why you have a peak @ 1,4 bar. Buy a dawes device if your planning on running with the stock solenoide and that problem will go away, because the dawes will remove the spike in your boost.STIprdr said:Well the wierd thing is that my boost goes up to about 1.4 bar/kpa at around 5500-5800 rpm and from there the boost goes down to 1.1 bar/kpa and it stays there untill 7200rpm where I change my gear. I'll explain it a little better: I tested this out in second, third and fourth gear, at around 3000 rpm cruising as I start to accelerate slow to around 3500 rpm I'm starting to fell the boost and my boost gauge start to indicate positive boost ( don't know how much exactly ) and at around 3600-3700 I start to accelerate hard and my boost goes up al the way to 1.4 bar/kpa at around 5500-5800 rpm and from there the boost gauge goes down to 1.1 bar/kpa and it stays there untill I change my gear. And I was curious if anyone had this problem. Thank you very much and sorry for my bad english.
I had a typo in the last post, it's not a solenoide it's a Actuator valveSTIprdr said:I have an Apexi AVC-R which I hope to install in about a month or so. I'm not runing a stock exhaust and I thought if I'd list my mods list maybe you'll have an ideea of where this boost spike comes from. My mods are: headers + up pipe, TBE, sandtler carbon air box, aps front mount intercooler and an hks ssqv. Thanks.
