Outer Limits 4x4 Board

Within our customer group we have about six GU utes and wagons with TD42 motors some with and without turbos.

We all run about 35 or 36 inch rubber and even with the crown wheel and pinion change find the decent speed still a little fast.

Has anyone successfully installed an electronic or vacuum exhaust brake onto this motor and if so how is the performance.

Yep on an a Turbo 80 Series, perhaps you should drive down hill like me!

One Word- " Cockhoppers "

for any one else reading this check out the time i posted the original post and the post times of the replies from Lockee and Gueey, can you guess who has too much time on their hands.

I am interested in hearing from blokes who have something to offer rather than blokes who are too bored at work so they stroke themselves by geeking it up on the net.

P.S. That is a great looking nissan bar on the front of that family wagon of yours Gueey....if your into that type of thing!

Hey Fancy Pants.

How about a packet of Tennis balls inserted up the Exhuast pipe just before you descend down a steep hill
A hell of alot cheaper than Rockhoppers or an Exhuast Brake setup!
Just make sure you enclose the exhuast pipe with some saftey mesh over the end so you dont shoot the guy behind you.

Cheers Gueey with a Pussy Bar!

Hey Gueey, you should thank your lucky stars that the new leader of the third reich; Tonka is not moderating. You have blatently abused the off topic rule, if you are not careful he might put you on the band bus!

Surely someone knows someone who has fitted an exhaust brake.

P.S. Gueey; is it true that you once got your hair cut so that you could look like John Bon Jovi?

That is a sacrafice you choose to make to give the truck incredable control in very steep climbs and decents.
The only problem with Rockhoppers is if you want to exceed 30KPH in low range. But most of the low range driving were wheel placement and nagotiating difficult obsticals are required you are not exceeding those speeds anyway, anything that needs to be quicker i can do in high range.
My GU wagon on 35 inch tyres in its original gearing and being petrol was absolutly pathetic in steep climbs and decents.
After owning 3 GQs over the last 10 years i found the GUs extra weight to be its enemy for slow decending and climbing in low range.
Nissan GU 4.5 or 2.8 that have poor torque ranges at low revs are transformed with Transfer reduction gears.
"I personly never missed original low range in my truck, due to the nature if my driving i always run 35s in the bush and stockys for the road"

Hey snatch, i was having a look through some sites and i came across one that had some information that may be useful to you..
The site is http://www.drivetrain.com/exhaustbrake.html

i know you were having trouble finding something that would fit a 3" exhaust but this site may be the go

Cheers GIVEITABIT

What about searching the bus and truck wreckers for exhaust brake parts? You are probably in luck with the TD42 since being an engine designed for buses and trucks, it is going to be strong enough to cope with the addition of an exhaust brake.

Few years back a mob tried this market, didn't work out for them. Not enough demand.

Could you adapt something like Chris B's setup Greg?
I would just be investigating modifying a truck setup, seems to be the easiest way to go.

Prob could, havn't had a good look at how Chris has done his, but like all custom jobs, it comes down to $.

The mob who used to do it had a weld in section of pipe you simply glued into your existing pipe. The only negative was that it did give some exaust restriction even while open.

Cant remember all the facts but I read once re issues with the turbo getting hit with heaps of back pressure if operated at the wrong time crating probs.?

Valid point! Cannot imagine the instant back pressure would be good for a fast spinning turbine.

Looks like it may be easier to use the middle pedal more
