Vortex exhausts and Computer chips

Chaz
do you own a patrol? and how much power and economy would you think it increased it by. Also does it stop or lessen the "flat spot" of the patrol when taking off. Would you be worried about the longevity of the engine.

Fishaholic,
The flat spot is most likely due to the EGR valve not closing properly, a common issue with the ZD30. I do own a Patrol 3.0Di and have done many mods to its engine to try to improve longevity and durability. My car made 127hp at the wheels before fitting the exhaust, so it’s now most likely around 135hp, standard they make about 95hp.
There is heaps of info on this subject HERE and some of my mods HERE .

A mate of mine purchased a detronic from a diesel workshop down near berrima, and he had to turn it back two notches as it was as he puts it "HUGE" tows his boat like it's not there.
Hope this helps.

Although I have 95 series, the TD is the same apart from yours having a shorter and more direct air delivery from the driver's side.

I fitted a Dtronic (yes that is the correct spelling). It provided a marked improvement at the bottom end of rev range. A Dtronic is not adjustable so your mate couildn't have fitted one of those.

Recently fitted a mandrel bend with 3" dump pipe which allows even freer revving from quite low revs. No turbo lag, in fact I wasn't concentrating the other day and let the clutch out before I'd hit the gas and she still took off. It will accelerate under load a lot better. You hear the turbo winding a lot more at low revs.

As an example I did a few tests (I don't drive like this all the time)

Smooth acceleration from 20 KPH in 3rd
Smooth acceleration from 40 kph in 4th
Take off from standing start in 2nd

Fuel economy is around 11.5 L/100 km on a variety of roads and conditions including hills, freeway and town driving.
