I meant to post this a while back, but some more feedback from a real track guy...

This is a customer our ours that reached out to us a little over a year ago. Concerned with the sustained lateral loads the 818s were seeing on track (and they are impressive out of the box!), but he did not want to go to the extreme of going dry sump if it was possible...


I finally got the car out yesterday at lunch time. I have made a few chassis and minor aero tweaks since my last outing and have made improvements in the feel, comfort and balance of the car.

Anyway what is important is the KB pan, Oil Control Valve and Crawford Air Oil Separator all are working well together. Oil Pressure under load throughout the run (25 minutes) stays steady at 74-76psi with oil temp of 220* pulling 1.5 plus lateral G. Off throttle/idle is steady at 55-56psi. (stock EJ205, TGV delete, JDM V37 twin scroll turbo, header and up pipe 285WHP on pump gas).

So the great news for me is confirming my determination not go to the expense of a Dry sump (and prove that a wet sump will work on these cars) so far has been validated.

For KB I am so please your products work as advertised, looking at both the AIM and Cobb data I am seeing 18psi boost, zero knock and intake air temps close to ambient at the throttle body with a STi TMIC. I am far from a Subaru expert but believe that great percentage of the guys that are knocking out rod bearings is more than likely due to detonation and not oil starvation if running a set up close to mine.
