That's going to look pretty ugly if the airbag goes off, but I suppose you're going to say that you've disabled the bag so that you can divert your attention by minding a lot of useless information. When I have a problem, I run a gauge into the car, otherwise the stock instruments are fine.

As for using the gauge to detect a stuck wastegate, the overboost protection system will prevent that from being obvious, even with a gauge. And if it's stuck open, your right foot will know. Just admit that it's for fun, I can accept that.

No airbag on an '85...

Hmm, my boost gauge at 28psi would not agree with you.

I love knowing what my car is doing, loved my BB Wanderlodges with 33 gauges in view of the driver, always knew how hard I could push it.

True that "idiot lights" and other indicators/protection are designed for ease of operation, but knowledge / information is so much better.

Wow...now that's impressive!...and a DIESEL 107 to boot!! That's my kind of project. Too bad you're in Cali...would love to see that bad boy in person. Any pictures you could share of the engine compartment? Performance numbers? fuel mpg?

W..O..W...read the whole thread, including Druk's foray into a 107 with a 606 engine. Exceedingly impressive...what a labor of love. Makes the "plug and play" 5 speed conversion of my 190D 2.5T look like child's play!

Very nice indeed.

I've given the idea of re-labeling the "economy" marking to "turbo" and have changed my mind. In keeping with the original intent of the gauge, after re-indexing the needle for turbo diesel use it will still in fact be indicating the relative fuel economy. For low/no boost driving it will read toward the left side. Under boost during acceleration, it will deflect to the red right side zone indicating lowered fuel economy. For boost pressure reading purposes, I will calibrate it so full rated boost will have it touch to the right stop. Any reading less than full deflection to the right will tell me I'm not making the full rated boost.

What will indicate overboost / wastegate failure?

...Unusually swift acceleration...lol.
