Ok I'll probably open a can of worms
What are the pros and cons of an intercooler ?
Local auto transmission place in Kunda Park ( near Maroochydore ) said they did 1 recently for Tim ( I think) of Nambour.

I intercooled 196.
Then I squirted more fuel in until the flat out exhaust temperature was about 500C.
I reckon I got a nice increase in max power.

Peter,
Interested in your intercooler on your website. Where did you get it? Did you plumb it by turning the old turbo to inlet connector upside down, going down on the turbo side and then back up on the other side over the top of the engine and back into inlet? That looks like the easiest route but I wonder about the big increase in distance and volume of air betwwen the turbo and the inlet compared with standard
Also I have been looking at trying to fit 2 extra shocks to my XT front end. Did 196 have two or four standard? (not sure what vin number was the first LT)
cheers
Rick
P.S. I am getting closer to finishing structural conversion of #149 busbody to camper. ..been so much work I think it may have been better to start with clean sheet do the camper from scratch as you have done. 196 is great example

I had a specialist in Adelaide fit it Rick. It was built for the job. Don't have a clue beyond that, except it did allow more fuel to be burnt at full throttle. The old turbo inlet is upsidedown from memory.
XT196 had single front shocks. I added the second pair. Big bolt and some small webs at the bottom have done the job well. Top was easy too, just another big bolt and some plate to get it in the right position. I was worried about the lower mount strength, but not a problem in 160,000km.
Cheers,
Peter

Did you find the extra two shocks on the front made a lot of difference to the ride and handling? If so, in what conditions?
Cheers,

Pretty hard to judge Alister as I added them soon after I got the vehicle. I figured that the later ones had twins as standard, so it was probably a good idea.It is certainly "not over shocked" though.
I have been running 'garden variety' Munroes because I had some second hand ones. I only recently fitted a couple of new adjustable Powerdowns and I adjusted them to about about half way. Seem great and they were under $100 each.
Would seem like a better idea to have 4 soft ones than 2 hard ones in terms of heat generation and shocker life and fade although I have to say the OKA is very kind to shockers.

There was more said about shock absorbers here.
On intercoolers, there was also this thread on the old forum.

Hal have you got a link or a copy of the article on your mods to the air intake tract, I've often thought that it would be restrictive.
thanks

Wrong vehicle I think Peter, mine's close to standard. If you were looking at >>The airbox is a big restrictor on an OKA and hope to have full figures with all options soon. See my home page for the airbox upgrade we have done.<< that was David Hallandal being quoted, and his homepage has air intake info down the bottom.
