I was wondering for the people who have a remote turbo, on the oil return pump is it alright to have it on sull speed all the time? Or should teh speed vary like the sts kit. I have a mocal pump and wanted to know if that would affect the life of the impeller when the oil volume is low.

Another question is what size of a nos nozzle should be used to restrict the oil flow on the pressure side?

Right now the hot and charge pipes are made and I just need to work the small stuff out before it will be up and running, thanks for your assistance.

 

I don't think it would hurt anything to run the pump full speed all the time. I think STS runs it a slow speed (9volts) during nonboost so it's quieter and they don't need the pump capacity with no boost. These dang pumps are noise when running at full song.

As for the restrictor, STS doesn't run one, just a check valve on the inlet of the turbo to keep oil from filling the turbo after you shut the motor off seems to be enough of a restrictor.

Good luck! And keep us posted.

 

Thanks, so the sts one is controller with a pressure switch referenced off boost. I thought that using oil pressure or rpm would be more direct, but I guess boost also goes up when those do.

Earlier on some people's post I was that .030 or .070 jets were used to on the fitting from teh oil filter adapter to lower teh oil volume going to the turbo to prevent oil seeping past the seals. So a brass check valve is enough to get the job done.

 

Yep. When the turbo is making boost is when it is spinning the fastest and using more oil, hence the need for more return pump. I have used .060 oil restrictors in the past, on a S-10 I did, but my STS kit doesn't have any restrictors in it and it works fine.
