oil pressure on turbo?

[boredpilot]

Hi guys, fitted the turbo to my MG Midget.

Feed for turbo is comming of the oil pressure gauge. Can anyone tell me what kind of pressure you get on your mini turbos.

Not sure if mine is low or as expected.

Its 20psi driving and 10 when hot and ticking over. Dont know if the turbo makes it high flow low pressure.

I used to have around 40 driving and 30 ish tickover before putting the turbo in

Any ideas?

metro turbo uses a larger capacity oil pump, pump may be overloaded?

turbos need high flow and low pressure 20psi is ideal

Thanks for the answers, wasnt sure if there was something I missed in the conversion.

But what about the rest of the engine? 20PSI is too low to provide adequate protection to big ends and mains IMO, especialy with the extra load the turbo will be imporsing on them.

Ive asked the chaps on the turbo mini side for suggestions, ive packed out the pressure relief spring and thats gainied me 10 psi but its still now 20 idle and 30 driving.

Guessing a different oil pump now
