Van,
Do you think that the HV oil pump makes a difference in engine life/reliability given that the majority of the parts are splash fed? Or is this simple a matter of more is "probably" better so why not do it. Since you are rebuilding these engines all the time, do you see evidence of oil starvation? You know, blue bearings, severly worn cams, lifters, rocker arms, etc?

Howdy .
$250 is lot of money for oil pump. Therefore , I let Shawn be the guinea pig.
Will see, I will report back.
in opinion .
It is oil distribution is important.
not hi volume or pressure or lack off

A high volume oil pump for a CJ750 is a lot cheaper than $250. They have 15mm impeller gears compared to 8mm(?) for the Ural.

When I do my rebuild (or have Van rebuild it :D ) I'm definitely going with the Raceway pump.
Considering what people spend on skidplates that never go off-road or carpet kits for sidecars that are devoid of monkeys 99% of the time, at least this farkle has the potential to actually do something.

Niteblues seat cracked in exactly the same place.
And while not exactly skinny, he isn, a heavyweight either.
He had to stick two rolled up tow straps under it for support and ratchet it down while we limped out of the Pines.

Nice vids.

I agree, and I will be getting the heads, valves, pistons ceramic coated like Scottolds did for his rebuild, read about here and checkout the pics.

Damn, I just might break down and buy the pump now, wifey/monkey not going to be happy as I already have a bunch of stuff for the Ural waiting for me at home, but hell whats one more part.

Would be nice to get some NEW updates from riders that have already installed this pump.

Please.
keep in mind . I m not promoting raceway oil pump.
I m not saying good or bad about pump.
I have no first hand experience with raceway pump.
I have no connection with raceway.
I m just helping a friend .

I have one of those Raceway pumps I plan to install on my next rebuild. The last time through I saw some areas in the oiling system that I thought could be improved, I don't know when I'll get to it as everyone is running OK right now, and I'm currently working on a diesel conversion.
I just wanted to weigh in in favor of the potential of this Mod.

Happy trails,

The oil passages in these engines are meter in some placed with orifices. So increasing volume will result in more pressure and very little additional flow in these areas. You also have to consider that if you flow more oil, you must also be able to return more oil back to the sump. So the return galleries might need to be opened up. If you don't you run the risk of flooding areas like valve covers which could in turn result in oil down the guides and into the combustion chambers. I trust Raceway has looked at this and determined that the engine can handle the added flow where there is indeed added flow.

If you read hot rod articles for plain bearing V8 engines, you'll see that high volume oil pumps are normally not needed and often do more damage than good. A plain bearing develops its oil wedge on its own without the need for pressure. Pressure just assures adequate flow given the feed line sizes.

Here's an extreme example. An industrial gas turbine that makes 26,000 horsepower, runs on two plain bearings that are about 8 inches long. The journal is probably about 12 inches in diameter. The oil pressure for that machine is set at 25 psi and is regulated to that pressure regardless of rotor speed. The bearing simply needs an adequate supply and it will form the oil wedge as it spools up. You could increase the oil pressure which would attempt to increase the volume. But chances are it would just cause turbulence in the oil flow, air entrainment and probably bearing problems.

Oil lubricates and cools. Once a bearing has adequate oil, more does nothing. More flow will remove more heat if you can move the oil thru the bearing and thru the passages.

So, maybe with a splash system that is fed by a pump, having more to spash about does help these engines. But I'd like to see it in action. The oil path in these engines that feeds the splash system is a bit on the tortuous side.
