The stuff you have to do to make the turbo LS work is amazing. Not sure but does a dry sump system do the same thing pulling both motor and turbo if connected to it? I'd love to do this to my e36/7 M roadster getting the glorious V8 sound and turbo noise.
@@SmooKGzuz yea, if you can see under the turbo I made a small scavenge tank, as well as a vent that does into my valve cover. I also used a smaller feed line. I bored out a ball bearing feed so that it’s a little smaller than the journal bearing feed. Works great
Do you have a breather from the turbo sump back to a catch can or anything ? Makes sense to have one so you're not trying to pull a vacuum at the turbo drain
I had just found out that this is the reason why I was finding so much oil in the cold side of the turbo. I had a turbo timer running to “empty the collector”, but found out that this very same pump could easily pull vacuum from the sump and it would pull oil past the seal. The issue was resolved with adding a voltage regulator (to reduce the power to the pump, as we don’t need it to pull 3 Gal/Min), and a vent to act as a vacuum breaker.
Thanks! I’ve put over 3500 miles on it and it’s been great so far. I’ve also sat in traffic and taken long drives as well and have never had a problem.
Not only is the oil backing up bad on your turbo the oil being mixed with the air/fuel mixture lowers the octane rating of the fuel that's being forced into the engine. The lower octane fuel being burnt at that time can lead to detonation and you already know detonation will kill an engine quick. My question is does the oil reservoir prevent the pump from running dry at idle speeds or does it hurt the pump to run dry for short periods of times?
I checked out the pump from your link and the specs say, 'Designed for intermittent use only. Duty cycle: 30 mins.' This would seem more like a fluid-transfer pump that a pump that could do a five-hour road trip, no?
Also said it was out of stock, here’s the new link amzn.to/3qISjRi Yea I see that in the description, but honestly it’s worked great. I’ve put over 3000 miles, and hours of driving on it with zero issues at all. I’ve had others use it as well no problems.
Doesn’t this pump only have a 30 minute duty cycle so after 30 minutes it’ll start slowing down then flooding turbo. Having issues even with a Marcos scavenge pump
It slows down and or shuts off for 1-3 minutes for motors to cool down then another 30 minute cycle. That’s why it’s always important to have a drain tank.
Yes, key on power, if the key is on it’s on, I might do an override so I can sit in my car without it running constantly, but I’m scared to forget to turn it on before starting the car.
3/8 NPT. You can buy fitting 3/8 NPT to AN10 usually or whatever other size you want. Make sure it’s NPT and not BSP. They thread slightly but not fully and you strip the threads if you force it, and it’ll leak.

That’s a good question! it might, but this is a lot cheaper than going full dry sump which is like $3000, this was $65 lol.
@@LowBoostFilms $3k... ouch
@@LowBoostFilms I have the same pump but still get back up. Should I restrict the oil flow going to the turbo or make a tank

@@LowBoostFilms Appreciate the insight man. Ready to drive the e46 on the road and finally found a video that helps

Yea, I do, I have a vent hooked up that goes into the oil filler cap. I had a catch can but it did fill up quickly.
It is okay to be under vacuum, that is the factory setup, crank case is always supposed to be under vacuum

I'm curious how you attached the sump so close to the drain flange, do you have pics of that setup posted anywhere?
Yeah, I have a video on it in my build series might be episode 12 or 13.
Great video. I was wondering if the pumps had good longevity and could be used on a daily reliably. The sump tank is sweet too.

it lasted 4 years and 7500 miles for me. I replaced it with the same one.
@@LowBoostFilms, the price is right, that's for sure.
Is the oil drain tank welded to the turbo ?
Bolted, the drain is welded to the tank though
Hi. Your link shows this info for the scavenge pump. (Designed for intermittent use only. Duty cycle: 30 mins)
Also said it was out of stock, here’s the new link amzn.to/3qISjRi Yea I see that in the description, but honestly it’s worked great. I’ve put over 3000 miles, and hours of driving on it with zero issues at all. I’ve had others use it as well no problems.
That's what they all say due to warranty reasons
If you have a tank drain, you should have no issues.
Doesn’t this pump only have a 30 minute duty cycle so after 30 minutes it’ll start slowing down then flooding turbo. Having issues even with a Marcos scavenge pump
Not at all, I’ve driven it for hours at a time and it’s been fine

how long have you been running it?
3 years now
Do you just have it wired to 12v? And ground?
Yes, key on power, if the key is on it’s on, I might do an override so I can sit in my car without it running constantly, but I’m scared to forget to turn it on before starting the car.
@@LowBoostFilms
Use a relay, with a 7 psi hobbs switch in the oil feed to trip the relay when key is on and oil pressure above 7 psi.
@@8SecSleeper that’s a good idea!
Do you have a video of the pump with oil going through it
I don’t, just 3000 miles of experience
@@LowBoostFilmsended up using that pump for about a year now no complaints with it & it gets the job done on my 1100+whp car .
Can you give a part name for that pump?
I have a link to it in the description of the video
It doesnt work for me so that why i asked.
Do you remember what size threads are in the pump?
I don’t remember, but it comes with basic fittings you can take to a store and match up.
3/8 NPT. You can buy fitting 3/8 NPT to AN10 usually or whatever other size you want. Make sure it’s NPT and not BSP. They thread slightly but not fully and you strip the threads if you force it, and it’ll leak.
Read the description in some of the chinese ones they have 12mm straight thread.
Still going?
Believe it or not it crapped out last month, the cold may have done it. Making a video on it soon. But $80 and lasted 4 years. Not bad at all
