Default ACL Orbit High Pressure Oil Pump

ACL shot me over a free Orbit series high pressure oil pump to test out and run on one of my built motors. Going to be doing pressure testing, and stress testing with this unit. Hope to have some results back before the end of the month (July). These are already on a few motors however the lack of information/reporting back from customers is why ACL sent me this pump in the first place.

Here is a few pictures of the unit;







Going to take some measurements of the pump itself when I get home to my digital caliper, I'm pretty sure this whiteline plastic printed one is off by a few mm's.

We've been using it for a few weeks now. And took one apart. 12mm rotor, looks to be nitride coated and has a polished bypass. Www.facebook.com/area1320designs

The output pressure is higher than a JDM 12mm pump according to Jasper's findings on the 12mm pump.

I just shipped out two to Mr. Kopinga, me and him will compile data in this post. I'll have a pretty busy week and next weekend so it will be about 7-10 days before I provide anymore data.

Ryan - Thanks for the additional pictures and info. Anything else you come up with please post it in here.

I had noticed these were available...

Adam, thanks for the solid info and taking the time to get real data.

Hoping to have time and can come down your way soon.

Didn't notice porting but it has 2 shims preloaded.

No prob buddy. I was nervous about ripping one apart but Tim told me to haha. It looks to be promising and the fact that it comes with all new hardware and seals is great. For the price you can't beat it.

Check with your local speed shop but most retailers are selling them for $200. Although they are worth imho $300.

I'll have another post up soon with some Head gasket testing as well . Comparing all the top names in the head gasket manufacturing industry, including a few not known like Siruda.

^^^ LoL...... Same place I usually hide with all my 6-packs

On a side note. I did indeed order 2 units from Adam and will investigate when I get them. I am running a stock JDM 12mm D-AVCS oilpump on my engine now and it works fine but they are RARE. It's good to see that now they are available to the public with some minor mods which for the price is VERY reasonable. I will add more info upon further inspection.

Cheers,

Jasper.

Me too, I've tested a 10, 11, and 12 and so far I think I may go back with a 10 unless this ACL pump proves to be better for some reason.

I only ran the 12mm (untouched) because of the oil squirters on my ej22t block, looser rod bearing clearances, DOHC AVCS heads.
