Boost guage should read cira -20 on psi on warm idle

[PWG123]

Do you know why it would be reading such low numbers?

[mikey4410]

I am afraid i havent a clue with this mate.i just know all 3 of my starlets were near bang on minus 20 psi.sorry i cant help further buddy.

[PWG123]

ok mate thanks for replying.

It's negative vac it's fine bud

[PWG123]

Yeah it is -_▪..... cheers. At least it's running right. First Turbo so I was worried. We literally just unplugged every sensor and vacuum hose and can't find where the apexi is plugged into.....unplugged the apexi plug was still running and reading??.

All cars run vacuum (as the pistons create on the induction stroke) you'll read positive as the turbo spools and kicks in

Thanks. Just happy she's running right, the manifold I bought the car cracked and bought a zisco and fitted it obviously had no boost leakage so was a different reading.

That's ok mate mine reads about .06 negative vac on idle then moves into positive boost pressure once I start accelerating nothing to worry about there. Need any more help bud just ask away we are all here to help

Checked the bulb?

All turbo cars read in the negative on a boost gauge at idle and even at slow speed with 0 throttle position.

When you put your foot down or load the engine up, you'll instantly get 0 and then start to build boost

Was assuming no one was lame enough to fit a boost gauge to a diesel
