“Dear ARE, Moving from my third oil pump failure (NOT ARE pumps), resulting in 2 motor breakdowns, I was tired of listening to others on how dry sumps should work, so I did a research on dry sumps in the market. I have no earlier experience with dry sumps. I could pretty quickly make the decision to use the ARE system mostly based on their excellent service level and from other users. I went for the full system 4-stage pump and the Spintric.

My experience is very good, I don't see oil pressure reductions like before, and the whole system feels more reliable and safe. I opened the engine after 2 races and everything looks perfect. "

Here are some pictures of the car, in front the 2.0L with the Spintric®. At the back the 4x4 with 3.0L H1V8. Both datalog screenshots are before and after.

The cars are powered by 2 liter 4 cam 4 valve V8's  10,000 rpm.  The first graph shows the data on track without the Spintric® hooked up, 2nd graph is with Spintric®. Top line is oil pressure and spikes.  The Spintric® has all but eliminated the surges caused by air, and the mini spikes are normal oil pump fluctuations.

Great info but you and I knew that. Super product with great potential. A driver will never see those changes! Solid proof is what we knew. Constant oil flow is so very important to engine life. And a driver can't watch that during braking, cornering, etc.  Normal oil monitoring instruments probably don't show the variations either! GREAT JOB, Mr. Scientist!

Since using the Spintric® our engine has being able to maintain such a high oil pressure and we have notice that our oils loss over an event has substantially reduced....Thanks to Gary and his Spintric®

"We only use ARE Dry Sump Systems and the Spintric® air oil separator in our "Ultra 4" racing trucks. Awesome work.  Very talented fabricators." Eric's 650 HP LS engine is run thru the paces (and the air) as you see, and the systems are working flawlessly. ARE will be helping Eric with a new dry sump tank design to further aid in the "air maneuvers" that produce even more challenges for the dry sump system. Eric took First Place in their first race of 2015! Congratulations! The fabrication, welding, and instillation of all the components are truly First Class.

We were experiencing oil pressure and very high oil temperature problems in all the last racing events. After installing the Spintric® in our Dry Sump System we have solved that problem. Oil pressure is higher and oil temperature 20 degrees lower. " Now we need brakes that would only work as well! ha

I recently added your catch can and your Spintric® air oil separator to my ARE stage 3 dry sump on my Katech 2006 Z06. This is a dedicated track car I took the car to Willow Springs the next weekend, both days 105 +. The oil temp never broke 257 and the engine topped out at 215. Consistent amount of oil in the catch can each session. Oil pressure was very constant and stable. This is a MUST for anyone wanting the BEST for their high performance car.

P.S. 1st place both days in TTU. See you at the track

We use the ARE dry sump system on our racing engines, the systems work extremely well. I recently added the Spintric® to my own Corvette race car and immediately saw 10-15 degrees cooler oil and less foam in the dry sump tank an improvement to a system that already works the best!

"I recently installed your Spintric® air oil separator on my Katech powered C6 Z06 track car. I only have a couple track days completed since the install, but I already noticed a change in oil temps and oil pressure consistency. I think there will be a nice drop in temps once I can get out on track in the heat. I also noticed significantly less air in the oil being returned to the tank The water and oil temps seem to stay closer to each other. I can't come up with any reason not to install one of these on a race engine. Thank You for continuing to come up with innovative new products for those of us that want the best for our expensive engines."

"We had Quality Motorsports install an ARE Spintric® unit two months ago on our DE Track C6 Z06 Corvette #113. 113 has a purpose built LS7 engine making 575 RWHP and 510 lbs. RW Torque. We already had a ARE Stage 3 oiling system on the car and added the Spintric® to help in the removal of air and foam. It is doing great. Temperatures and pressures are very good. I would recommend this addition to Corvette ARE system to finish off the support needed."

Gary Armstrong has introduced a new version of his innovative ARE Spintric® oil-air separator, the original of which was unveiled at the same show a year earlier. Spintric® has no moving parts, cleverly exploiting the motion of scavenged oil as it passes the same de-aeration capability but has been downscaled to suit the lower flow rates associated with four-cylinder rather than V8 racing engines.

Reducing Aeration
Oil aeration in dry-sump lubrication systems can lead to lower lubrication efficiency by encouraging cavitation in the oil pump. The level of aeration in the oil is determined by a range of factors, including engine speed, oil type and oil condition, and can be a particular problem in high-revving large-displacement drag race engines. Not only does the high rpm of components such as the crank churn the oil to a greater extent, the oil also flows through the lubrication system faster. This means it has less time to rest in the sump or the oil tank, where air bubbles would naturally separate out.
Aeration caused by the rotating assemblies within the engine is not the only problem; it is also contributed to by the pump mechanism in dry-sump systems. Here the aeration occurs at the scavenge stage of the pump. The oil sucked into the pump is more of an air-oil foam, and as the oil is pulled between the pump's gars it is further aerated, which is why oil tank design is of utmost importance for maintaining oil condition.
However, a new device developed by California-based Armstrong Race Engines (ARE) claims to help reduce this problem considerably. A bolt-on fitment to existing lubrication systems, the device is called the Spintric®, and it relies on internal channels to 'spin' the oil and encourage air bubbles to separate. The device fits on the return line to the oil tank, and the aerated scavenged oil is forced through it, with separated air being channeled through one outlet and oil to the oil tank through another.
Spintric® has no moving parts, and Gary Armstrong, the inventor of the device and owner of ARE, claims that it separates between 30 and 70% of the air from the oil, depending on engine revs. Ultimately this means there is less air entering the oil tank, allowing the internal features of the tank to better remove the remaining oil.

After running my Corvette at Nurburgring 12 lap sessions,  my oil pressure is "rock steady" and the oil pump is not cavitating with air bubbles like it was before the Spintric® was added. The oil temp is down by approx. 10 deg F Attached are pictures of my installation, A quote to you from your dedicated Swedish Corvette racer.  Oil pressure is steady at WOT.

I tested a new product from Gary Armstrong at ARE on Monday and Tuesday at VIR. The product, with no moving parts, is called a Spintric®! It installs in the line returning oil to the dry sump tank. It removes about 75% of the air in the oil before it goes back into the tank. So, what are the results. Once the air out line was hooked up to the dry sump tank the oil level in the dry sump tank dropped about 1.25" to 1.5"! Oil pressure went up 5psi or 12%! Water temperature went down 10 degrees! I have a Ron Davis radiator so my oil temps and water temps are always low. Those with higher water and oil temps may see them both go down.
Our conclusion is with the air reduced in the oil lubrication is better, cooling is better and since the oil is denser it takes less room in the tank.

“ZO6 Corvette, Turbocharged, Spintric® just added, 15-20 degrees cooler oil temperatures from before!  Thanks!"


Spintric® Race Car

“I race in Dubai , and have been running the AREStage 3 dry sump system on my c5 Corvette for 3 years.  After blowing 1 engine running the wet sump, it has proven to be a asset to my engine, especially the 130 F degree days here. We added an extra oil cooler to the system which only helped the oil temperature by a few degrees.  Last winter we added the Spintric® to my system, and the last two test sessions at the track I have seen as much as 20 degrees lower oil temperature. The Spintric® has made that much less air in the oil cooler making the cooler more efficient, even in these crazy hot days. It really seems to work very well. The #2 cooler did not make more than a couple degrees itself, as mentioned.  A way cool device. Thank you.    "

“The Spintric® works very well it seems to have reduced the oil temp which would go in hand with getting less air in the oil. Thanks your all your help enclosed a picture of the installation."
