Oil Scavenge Pumps, what's the recommend flow?

3 GPM is way more than enough.
 
We use weldon pumps on many turbo setups we've done. From street cars that have over 40k miles on the pump, to one we've been tracking for 4 years now. Never one failure. Most turbos dont actually need much oil, especially the ball bearing center sections. Its a small stream that will actually discharge out of the turbo. -10 lines are usually even overkill for return setups

Whats important on a Scavenging pump is that its a positive displacement pump. We've found on some kits they dont provide a pump that is actually positive displacement and have seen oil backing up and blowing the seals on the turbo.

Good luck with it.

Regards,
Mase
