Thats true, you forgot to add that it regulates flow/pressure to the HLA's and then blocks the rest of the oil off, rather than dumping it into the head.
Which is why people comment on more oil in the sump, and less oil in the breather tanks etc

 

Thanks for the clarification JC evo1 and RSMike.

Since there are reports of some increase in oil pressure as well, I guess another benefit this has is a slight oil pressure increase for the turbo feed from the head.

 

bump for this thread - just bought a FP green DBB - do I need any other supporting mods in conjunction besides possibly the oil pan?

 

With the green I cannot imagine needing an oil pan upgrade. The HLA is a step in the right direction.

 

gotcha - so i dont need like the oil filter (which seems like it can be clogged), any special lines etc beyond with the green comes with?

 

I opted not to get this piece. I was in the market and was dissuaded from purchasing it. Partly because I am running a stroker motor. This coming from someone who has a ton of experience with heads and evo heads in general. The bottom line was that it wasn't good for cars idling under 1200 rpm and not necessary for cars not revving to 9000 or over.

Not good for cars idling under 1200 rpm? Even stock motors?

My regulator will not alter the oil flow or pressure to the lifters compared to OEM at warm oil idle in any way, shape, or form. The regulator only begins altering pressure to the lifters when the supply to the cylinder head oil gallery exceeds 15psi. This is not the case in a low idle with warm oil. 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,

what about idling with cold oil at 110 psi pressure and 1500 rpm, will my lifters tick more or less?...

 

so main point - no downside to this mod?

 

i just did this mod and checked my catch can. there is absolutly a lot less oil in the cans as compared to before. way worth the money, and a very simplistic install as well.

 

Thanks for clearing that up. I'll be getting one for my car soon.

 

I just built a 2.3 evo 9 motor for a friend, we installed this unit and the AMS oil pan. There is absolutely no lifter ticking even when the engine was idling at 850rpm(before I bumped it up).

This mod is well worth it for those that need it (ie those that push their cars hard with road racing, drag racing, etc..).

 

wow thats a nice part ill have to pick one up!
