    Was looking at Kiggly's website and seen this

    Kiggly Racing - kigglyracing.com

    Actively Regulates Lash Adjuster Supply Pressure to a Constant 15psi
    · Accomplishes this by Restricting Flow Instead of Dumping Extra Pressure like the JDM Regulator
    · Reduces Oil Flow Into the Head, Keeps More Oil in the Pan
    · In Some Instances can Greatly Improve Oil Pressure at the End of a 1/4mi Pass - Click Here to See Results from the Kiggly Racing Drag Car
    · Air Bleed at the Highest Point Helps Oil Quality and Aeration to Lash Adjusters
    · Fits DSM Style Valve Cover Only at $150 While Supplies Last
    · Universal Fit Version (DSM and EVO 8 & 9) $175

    Anyone ever use one before and any feed back?

    15psi just sounds weak for street car. I know rau used to regulate his to 30psi to keep lifters from pumping too much. I just dont think this is wise for street car mod.

    What basis do you have for thinking 15psi is too low? I ran some old spring durability tests at about 5-7psi and 8000-9000rpm and didn't see any wear. I believe the JDM dump-to-head regulator is about a 15psi set point as well, and that had to pass mitsu's OEM durability testing. I had this setup on my beater for a few thousand miles (5k intervals) with crappy old oil before any of these were sold to the public.

    If you ever see your oil pressure light flashing at idle that means 5psi at the oil filter, which is probably only a couple psi at the lifters. Things don't go bad under those conditions. All the lifters and rockers really need is enough oil to stay wet and no air going to them. Extra oil is just to cool the springs, which really don't tend to run that hot in these engines anyway.
