Threedogs is also right, coming up to the Murray is all up hill.

Not quite. Waste gate gets rid of exhaust gases which in turn controls turbine speed and boost. In a diesel with no throttle body, the motor will take all the air it can.

With the inlet forward the engine dies when slowing below 40kph (leaning out?). Economy 25l/100k either way. 4 different mechanics, thousands of k's and no one knows why! A mate with a TD42 swears forward facing gives better power and economy.

Give it a try.

Pretty common on gas motors. Pretty sure there was an equalization pipe or similar that once installed would resolve the issue. Otherwise, turning the snorkel backwards works too.

And sorry, didn't realize previous poster have gravedug so far back :p

Came across this thread by mistake but had me intrigued, has anyone else tried ?
I turned mine round and seem to be getting more power , not sure about fuel consumption just yet .
