fuel economy

Thanks for the reply stew, it appears that my consumption is a little on the high side. Interesting that you mention the Hiclone as i have just been looking into it myself - looks like it might be worth a try.

Damien, please have a look at overlander.com
at there forum, there is a lot of discussion about the hiclone, add some common sense, and realise that you can't get a mechanical efficiency for a $ by putting a bit of finned metal in a manifold..that stopped in the early 1980's, when the aussie car world was dragged into the european equivilant of the 1960's.
vehicle manufacturers spend millions trying to get the best efficienies from engine designs..and occasionally australian importers let them into here, then people want to go the the local wankmart and buy some thing that sounds good, looks allright, and has some non-scientific unqualified assessment. Please talk to your local mechanic or 2..Sorry if this is harsh, but god, is a piece of finned metal worth that sort of money, how does it transform into reduced energy consumption that engine designers don't realise.. betcha brockie and dicko never had them..
more power, less fuel consumption..give me a break..in other words, something for nothing..from an already impressive turbo diesel, next it will be a winged keel for the inlet manifold!

Thanks for the follow-up John, your advice is appreciated. It's good to get some feedback from people who have actually trialled the hiclone.

John, I too have a 2.8Turbo GU. My economy has decreased by about 10% in 80,00km. What sort of economy do you get and can you comment on the cost and effect of the new exhaust. Many thanks Jim

Thanks for the follow-up Owen. I've pulled the air filter out a couple of times after driving in dusty conditions & found it was pretty clogged up. After a few knocks on the ground it seemed ok - maybe time to change it though!!
