I am looking to install the E.R.T. Products or Baisley Hi-Performance oil pressure springs in my 2009 SG to boost the lower and mid range RPM oil pressure.

E.R.T. offers the oil pressure spring kit with three springs. Anyone know how much increase in pounds or % for each of the three different springs?

Baisley Hi-Performance Products offers two oil pressure springs increase, 15% or 30% increase in pressure.

 

I put the smaller baisley spring from fuel moto in mine when I did a cam job. Pressure increase is substantial at idle, cruising, start up, you name it. If memory serves me correctly, the higher percentage is for race only.

 

Ive got the Baisley 15% spring. It works as described

 

baisley, very high quality spring with a very even compression/return.
