Hi, just finished my venturi delete and added a boostgauge. It also had à negative Side to measure vacuum.

What should it be at idle? Now reading -0.6 bar (-9psi)

 

That is 18 inHg which is pretty good (and normal) for warm idle.

 

Good

 

Ok thanks both.

 

That's exactly what mine reads at warm idle - 18 inHg - on a Autometer Sport Comp. Unfortunately, it fell out of calibration a month or two ago, so I've got to send it in to have it re-calibrated

 

Just took some pics of the new gauges installed. Used the third blank cover to display the 1986 porsche collecter coin. Just liked it there.






The 0.6 bar vacuum is with cold engine.

 

Looks good!

 

What is in the middle?

 

He explains that at the top of the quote you re-posted...

 

Yep. The 1986 Porsche calendar coin.

 

oops my bad thats pretty cool

 

Looks really nice! I find the far right gauge gets blocked by the gear shifter in the odd gears. If the steering wheel is on the left side, you might want to put the boost gauge on the left, since you don't need to check the oil temp "in the moment" like boost.

Is that an A/C buttom on the console? Do you not have the failure-prone climate control box in the dash like the U.S. cars?

 

After market airco. Airco was an option untill 1988 on the 951 here.

I never had à problem with reading THE oil temp when i had just one gauge on the right.
