What psi is too much for the oil return line before I have to worry about it flooding out the turbo?

I have no inline pres. warning system and I was going to buy a universal hobbs switch, wire it to a warning light but I'm not sure what psi to get.

I say any . I run a -10 on a 45degree from front to back. But with the remote mount i am not sure . Is it like a sts system and do you have a return tank and a pump.The warning lite is a good idea. Tell me some more of your system. I will be glade to give you my thoughts.

I have a -8 return line and have close to 80 psi wot. I do have a restrictor on the feed I dont rember the size but it will vary depending on your build and turbo.

It is a used sts and I have a -10 line returned to the oil pan with a Weldon pump, I'm using a relay so the pump always gets full power (I have no sts harness). I do have a restrictor on the feed into the turbo. The sts kit normally comes with a warning system (pressure switch) that activates when too much oil builds up in the return line. I would guess it mounts in between the turbo and return pump.

I was thinking about making my own warning system, but I'm not sure how sensitive of a pressure switch I need.

I'm going to use a dash mounted LED wired up with the pump so I'll know if the return pump quits.

Should I not use a warning system for oil pressure build up on the return?

That is what I have a dash mounted led wired to the relay and pump. When the power surce is gone light goes off. When the pump fails light goes off

The setup you described should be fine for a LXs application. Between the higher power return pump + restrictor you'd have to be pushing a LOT of oil to overpower it.

As for a warning system....yes, I'd personally add one. I had my STS wire harness melt on me during the 2008 Hot Rod Power Tour. Tore it out of the car (on the side of the road ) and installed a light exactly as described below. Used that w/ no issues for another 4 months/5K miles.

Alright thanks for the info I'll just do the warning light to keep an eye on the pump. No inline pressure switch.
