Comp. Oil pump comparison...

[Zvoiture]

What is the difference between these two?:

Competition Oil Pump (15010-A1115) W/external adjuster above

Turbo Oil Pump (15010-S8000) W/external adjuster above

Please use 'standard' ZX turbo oil pump as standard for comparison.

as I read Honsowetz' book, the competition pump has stock volume, higher pressure

the turbo (S8000) pump 15% more volume

on both, the external adjuster allows you to choose what pressure.

Turbo pump has 15% more volume. Competition pump runs 90psi+. Both can be fitted with an external pickup to avoid the internal feed gallery restrictions. The next step from there is a dry-sump....

Fit a turbo pump if you have a turbo (no kidding...) or an external cooler. I've got both & pressure is around 50psi, hot (80 deg C after the cooler), 3000rpm, measured at the stock location on a mechanical gauge.
