This car certainly has more dials than a popular Pizza chain! They say that you can never have too much information and this owner certainly proves the point with everything from a tacho and speedo to oil temp and pressure gauge. I wouldn’t be suprised if he’d shoehorned in a barometer for good measure. The dials are mounted into gaps in the dashboard and when space became short they were mounted on separate pods. You could equally get them installed in a custom build dash if you were so inclined.
The most useful dials are oil temp and oil pressure and boost if you have a turbo. Using these you can determine that the car is in peak efficiency or about to have a catestrophic engine failure.
