Fitting a tacho to a Perentie

The biggest issue I have when jumping between vehicles is remembering not to flick the wipers on when turning. :censored:

Gear changes, not so much. Even switching between a 4 speed and 6 speed manual. Once you know the car, you rarely look at the tachometer, if fitted.

Drive only the Perentie for a week. That'll learn ya. :D

Exactly. When my clutch hydraulics failed I just worked out what speeds to change gears. Drove over 300 km like that...

I'm not sure whether you lot realise this but a 4cyl turbo diesel sounds different to a v8 petrol.

Think I've had 3 4BD1's and dozens of V8 petrols with LT95's

Whats with the mental block that says you need a tacho? speedo, same deal:p

What ratio diffs do the Perenties have?


Cheers, Mick.

Google tells me 3.54 on the 4x4 and 4.7 on the 6x6.

What's the relevance of the question in this old thread?

Directly related to RPMs of the engine.

Odd, that. The faster the engine spins, the faster the wheel spins.

There was a thread elsewhere that mentioned diff ratios. It also referred to transfer case ratios.

I thought this thread was very interesting. It's full of diff ratios, transfer case ratios and gear box ratios.
