I know there are a few members here with turbo kits that use use an electric pump to return oil from the turbo/turbos back to the oil pan.

Just wondering what you guys are using for pumps?
Any problems and what were they?
How long has it been runing on the car without problems?


I bough an electric scavenge, it was made for the APS TT kit for the Z06:

I got all you see there for only $200, still can't believe it. It came with a checkvalve, 12v selonoid, relay, mounting brackets...ect. I am about to start fabricating my own kit and I will need a scavenge pump so I though I ask the guys that use these pumps.

Thanks

 

Not sure which pump is on mine. Chris or Larry can chime in and answer that. Mine doesn't rely on the pump to keep up 100% though. Oil drains into a small scavenge tank then the pump pulls from there. Also the pro-efi controls the pump and turns it off if rpms are <300rpm (that way when you turn the key on it isn't being burned up from no fluid going through it)

Have almost 5K miles on it with no problems. Scavenge units inherantly have a puff of white smoke out the exhaust when you let off after a hard pull.

Thanks Tom, I too will make a small catch tank under the turbo. As far as pump controll, I will use a 30psi (n/o) oil pressure switch and two relays to trigger my two speeds. So when the oil pressure is under 30psi my pump will be at 1/2 speed. When the oil pressure reaches 30psi the switch will provide a ground for my 2nd cicuit and will turn the pump to full speed. I figure this would extend the life of the motor and pump.

 

include indicator (idiot) lights in your harness so you will have visual confirmation the pump is running.

 

I really don't see the point to that. The motor could be getting power but if the gears are jammed it doe not do anything for you.

I will be getting a flow indicator and installing it on the oil return line just befoer it goes back to the oil pan. This way you know 100% that everything is working.

 

If the pump failed I think you'd know the second oil filled your catch tank and the turbos had no where to send the oil.........HOLY SMOKE. Granted it'd always be nice to know before then.

jammed gears will blow a fuse (if you have one)

 

This is by far the best "Oil" scavenge pump on the market
We carry them in stock and use them with our turbo kits.

Exa-pump.Exapump (oil scavenge pump)

Most of those other pumps are inteded for thicker fluids like diff/gear oil, etc..

Let me know if you have any other questions.

Chris

 

Yes that is true, to be honest for some reason that never crossed my mind.

Thanks for the offer Chris, and the pump you linked there was the pump I was going to use. I came across this deal and couldn't pass it up. I got everything that I needed, and from what I have read it's a really good pump.

 

Thanks Chris,
Thats the one they have on my car (obviously, since I have a SP TT setup)

Tom

 

Even better then this one?

Yes, that one is very similar to the SHURflo that lots of other companies re-brand. It's a great pump, but I the exapump was specifically designed for oil.

Chris

 

Any way to get rid of that puff of smoke between shifts?

 

I have no clue, but I have seen it with most any car that runs a scavenge pump setup (ls1's, z/g, pony cars). Doesn't due it everytime, but most often after full throttle pulls.

Tom

 

I wonder if adding a breather to the scavenge tank would help? From what I have gathered this is the prefered way of doing it, to alleviate the pump from creating vacuum.

 

yea, there has to be some cavitating too with the pressure changin from oil feeds from the turbos.

 

I asked because I dont see a vent on the SP tank.

 

Nobody else is using a scavenge pump?

 

I'm using a scavenge pump on my supercharger due to how low it is mounted. Thus far I have not had any problems with it. I forget what brand I got but it was about $300 for it.

 

Us STS owners run the pump from here - http://www.rbracing-rsr.com/oilsystems.htm. It's one of the white ones toward the bottom of the page. Haven't heard of any failures yet with the Z STS guys. However, just some Googling came up with some other owners who have reported failures.
