Whomever recommended it wasn't appropriate for engines idling below 1200rpm must not understand how it functions. It does not regulate or restrict oil flow to the lifters until there is already an excess. We have plenty of regulators out there with low-idling engines and no issues whatsoever.

The stroker motors actually have worse windage at the same rpm compared to standard crank motors because the rod big ends are swinging at a higher velocity. The HLA regulator delivers increasing improvements with both higher rpm and increased blowby. Something like a bone stock engine that seals up great and is only used to low rpm may not see a significant change. But as you push it harder, the improvements will increase.

I'm sure there are plenty of people out there who can chime in that even in 3XXwhp sub-8000rpm setups they saw less oil in the catch can after installing our regulator. For everyone that has seen this, it is direct evidence of more oil remaining in the oil pan during heavy usage. Less oil in the catch can is the result of less oil suspended in the head and valve cover to be pushed into the catch can due to blowby. The only other place that oil could be is down in the crankcase and oil pan.

Thanks for reading,

great mod regardless, but only part of the equation when it comes to managing oil starvation for racing
