Anyone have any thoughts on dry sump component longevity (specifically the pump).

I'm thinking of getting myself a dry sump setup, but I'm worried about the pump wearing out prematurely on a road/track day car. I'm mainly concerned because every dry sump pump I've seen so far has had the shaft connected to the pulley running through a machined aluminium housing with no other bearing material (ie like an aluminium sleeve bearing).

My concern is that when this housing wears, there's no way to replace it, and also the pulley would put stresses onto one side of the housing due to the belt tension pulling on it.

In a race car that runs for 10-15 hours a season it probably isn't a big concern, but how about a road/track day car that does 150 hours a year?

 

Wrong place to ask, a dry sump setup is worth more at least half the cars on here. 22B forum is probably a better option...

 

Plenty of "Dry" sumps on here Banny but not the good kind

 

Fair point, I'll move it over

 

The Zen, now RCM dry sump input shaft from the pulley end has a changeable bearing, on all my engines with these pumps fitted wear has not been an issue, the only time it rears its ugly head is from any sort of engine failure / debris getting into the scavenge side, as apart from a gauze filter there is nothing to stop it, but that's not the fault of the pump.

 

Thanks Paul, perhaps I need to get a more expensive pump

 

Mine is on one of the original zen kits. It's completed 38,000 miles now

Just one belt change so far

 

it will be a damn site better made than a factory oil pump- will probably out live most race/track engines-they certainly dont last very long without one, high g cornering(usually with slicks) will do it everytime.
