stupid question i know

[kenchenzo]

i have an evo iv when its on idle and i rev the engine the boost goes up to 0.5 then drops how should it be when revving at a stand still thanks

 

[RsvRob]

No boost

Unless you have launch control with ALS

your boost gauge should not go above 0.it will sit at about -.5 ish thats what my iv sits at it will move when you blip the throttle

What does the gauge sit at when it is just idling? And what does it peak at? Could it be possible the gauge just isn't calibrated? Next time you're at a garage (a proper one) they can quickly plumb a gauge in to see how it compares to yours.

If you flat it out with ALS @-5* you'd probably see 0.5 bar, try using -35* see what boost you run ;-)

Sometimes mine goes up to 1 bar

Mine use to go to 0.5 too when reved on standstill I found it was due to the gauge as I was using a 52mm autogauge. Didn't happen when I changed to a greddy 60mm gauge

You will get a little positive boost when revving in neutral (just ask all the chavs showing off their dump valves in the car park).
