Does anyone know how much oil pressure lose u will see with a relocation kit?

 

as long as the pump is still is good working order and your main bearing clearances are within spec, 0.

 

It's common to see a 5-10 psi drop across the rpm range with the cheaper relocation kits. That's because they use small tubing and restrictive fittings and parts.

If you step up to quality AN and billit components, it will be much less. I was using Canton billit adapters and -10 line. I lost about 6-8 psi. Then I increased line size to -12, and gained a few psi.

The type of oil pump you use would also make a differance. Everyone seems to agree the mod and windsor motors don't need a high pressure pump. They can actually cause some significant problems in the windsor motors.

There is some controversy with hiogh volume pumps, though. As best as I can tell, a high volume pump should only be used if you have external oil components: coolers, Accusump, remote filters, etc. Otherwise stick to the SV/SP pumps.
