Thread: Donaldson in TD5

Personally I think the one you have fitted is too small
I have one on my TD5 and it almost touches the roof so is much wider
I have seen no negatives from using it apart from hitting trees with it

Thanks guys, I thought it probably too restictive as well.

I took it for a drive with the Nanocom reading out the Mass Air Flow, with regular Ram head & then with Precleaner


-------------------Precleaner-------------Ram Head
Idle..................56.2 g/hr..................55.5
60k flat road.......207.........................175
Flat Chat 4th.......510 @ 93kph...........530 @ 96kph

So I'd conclude the Precleaner is Ok to use , The Ram effect makes bugger all diferance, The TD5 would only get to 93 kph up that long steep hill with the precleaner on and made it to 96 with the ram head. The 60kph test was probably not valid I should do it again on cruise control to be fair.

So with only 3kph in it and the fact that I already tested better economy with the precleaner on I think I'll leave it there.

Just for comparison on that same long steep hill the 2006 105 series Landcruiser with 4.2L NA diesel would struggle in 4th I had to change to 3rd & made it up at just over 80kph.
