Yeh , hot oil soon brings out the shortcomings of the rubber impeller , I used one for the scavenge pump on my bike but ended up having to replace it with a couple of gearpumps

Hopefully my oil cooler With a cooling capacity of 0,110 KW will keep the temps down, it is a oil cooler for hydralic systems made by emmegi, it is fitted With a 24 V SPAL fan. I will find a suitable large oiltank to get some runtime before the oil heats up. Cheers /stephan

Hi Stephan
You'd need the 3rd stage wheel , even though it'd be a tad oversized , the 2nd stage would be too small a flow area
Cheers John

Hi Stephan You'd need the 3rd stage wheel , even though it'd be a tad oversized , the 2nd stage would be too small a flow area Cheers John That it is slightly oversized would it cause the engine to overtemp?i Guess it would(like when you have way to high gearing(or low,depending how you are seing it ) Cheers Stephan

Hi Stephan
You'd just need to calibrate the NGV area to suit by having a "shallow" approach angle to the wheel , as for efficiency, it'll still be pretty good :-)
Cheers John
