Fuel efficency, Turbo's, Extractors, exhausts and Injector Tuning TD42

[Ben-e-boy]

A gq wagon stock in good nick will make about 70-75 hp at the wheels. I know this as I asked various mechanics while I was getting quotes for my turbo install and saw their dyno shets of other customers. Before I turbo'd mine I had extractors, 2.5 inch exhaust, snorkle, k&n filter and a pump tune I made ( dyno proven) 88hp at the wheels. these little mods are good for about 15 hp. Its not alot granted but its near 20% increase in power, which is noticeable

I highly recommend you get you injectors serviced and advance the IP to about .84

I just got my 1st Patrol TD42 and put extractors on it, I dont rekon it made much differance at all but might of helped with fuel economy.

it wont make much of a difference with just extractors, if you exhaust is still standard size it will restrict your flow, if your air intake is still standard with pre-filter that is useless for good flow also

You could look on ebay, I think that you can pick up extractors and 2.5'' exhaust for $8-900 DYI installation.

Following this thread with interest as I'm going down the turbo route shortly Will be going into 3" s/s exhaust straight out full flow :-)
What are "extractors" though ?

I am getting 600 ks ATM same specs but 400k. 31s town. Slow as!! Just had pump done last week. Dont have current fuel usage yet.

Diesels love to breathe.
Get the air in: snorkel, k&n filter, hyclone
then get it out: Extractors and 2.5 inch exhaust

You will get benefit from doing the injectors, but do the pump at the same time

i have a TD42 with 412 000 on it. It was getting 12ks/l on the highway with 33" muds and 4" lift and had the same power and economy as my old stock td42 ute. I put a turbo on it myself recently and running 8psi with no intercooler and half a turn on the fuel screw it drives heaps better, doesn't get hot and i am happy as. I will need to get a better exhaust system and a proper tune and it should be really good. Not sure what fuel it gets now but i am expecting the smae or a little worse.
