BlownCorona Posted September 23, 2012 Share Posted September 23, 2012 want to borrow a known accurate boost gauge (or perhaps a tool if one exists?), as ive just put in a pretty nice Autometer ProComp gauge into the charade, and its reading 7psi, when factory boost should be 9.2. need to work out if my gauge is faulty or something weird is going on with the engine. on a side note, how would an engine boost less than what its factory wastegate should operate at? im pretty new to turbo systems.

craig_b Posted September 23, 2012 Share Posted September 23, 2012 ive got a cheap ass auto gauge or autometer one i picked up from repco to check my set up, can fish it out if ya like? wastegate flap maybe not fully sealing because its covered in crap on the seat? worn turbo? try gauge at different points in the circuit after the turbo? slight leak at joiners?

BlownCorona Posted September 23, 2012 Author Share Posted September 23, 2012 i had a shitty repco autogauge one originally and it was boosting to 9.5 on that gauge. but i dont really trust those cheap gauges (though it looks more promising than the topend autometer one haha.) just need a gauge that someone knows is acurate so i can get a bench mark. ill also check over the turbo and wastegate. if that gauge you have is accurate then that would be great!

BlownCorona Posted September 23, 2012 Author Share Posted September 23, 2012 also is it ever possible for a bov to open under boost? i can hear a woosh sound when it gets to about 7psi, but i pretty sure thats the internal gate opening?

Ranter Posted September 24, 2012 Share Posted September 24, 2012 Is your autometer one liquid filled? They're the only ones I've seen read wrong. Have a couple you can borrow HKS and Mitsubishi but they don't read in psi. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted September 24, 2012 Author Share Posted September 24, 2012 its not liquid filled, but it does have a weird fitting that could be leaky, as ill need to get a proper one for it. where abouts are you located? im fine with converting figures.
