Oil Flow Rate

[Alan Whitaker]

Hi All
Anybody know how much oil the 1UZFE pump flows at 2000 rpm ??

Many Thanks

I've never seen any official figures for oil flow rate at any revs.

Short of testing it yourself, which I would imagine would be messy and expensive, I'd rely on it being way more than sufficient for an engine in good shape.

Even feeding a couple of turbos oil wouldn't have any noticeable effect on flow rates.

Plenty of big builds over the years have never seemed to have suffered a lack of flow or pressure.

Hi
Thanks for the reply, I am trying to work out whot the pressure stage needs to flow on a dry sump pump. Due to the low engine I have to run a dry sump.

Alan,

You could try sending Errol (Username RMS) a PM as he's run dry sumps on 1UZ's in the past.

I'm sure Ash said something about oil flow ??

Many Thanks for the info, could not find any posts, may have the answer today from Pace as he is working out the flow on the 1UZFE pump gear set, I have there largest gear set on the pump stage but I know there are other pumps with larger flow rates.

what is the width of the dry sump gear?

oem 1uz oil pump is not much bigger than th400 trans oil pump
they flow 5-6 gals @ 200 psi

so estimate 3-4 ?
