If I can ever load the test results, the Amsoil products are included in the comparisons in the SAE J726/ISO 5011 tests.

 

You have your properties set so you cannot recieve PMs.

 

R2C - no makey drop in's....I'd be somewhat inclined to try them....somewhat.

 

One of the claims to fame at that filter website...

"There is nothing else like our PowerFlow Filter. It is a high loft, all synthetic fiber designed specifically for engine intake air filters."

 

Here is the restriction test. It was on a retailers site.

You'll see what I mean about high restriction synthetics.

These SAE/ISO tests use a flow rate of 400SCFM and fine dust which is appropriate for street performance cars.

 

^ Very true, and confirmed by Terry Dyson of dysonanalysis labs. I would not put it past NISMO to have possibly contracted K&N to mfg their filter for the NISMO CAI....just a hunch on my part.

 

R2C air filters came recommended to me by Terry Dyson back in June on my second UOA. Terry had not tested them yet but said that these filters are derived from Rolex Cup Daytona racing cars this company custom made. Terry recommended to me, Jason T as a point of contact.

Hey (R2C) Jason T., I woud be willing to test your filter and have Terry Dyson look at its performance on my next used oil analysis (UOA). I running with a freshly built VQ35 Rev-UP. You can see my UOA on the link from my previous post on this thread.

Thanks for the chart Dynamicperf. Do you have a chart of some sort of breakdown of filtration levels for the filters? Assuming the chart you posted is real and accurate, looks like the flow is there, now we just need to see how well it filters. (sorry for being such a skeptic, I like facts, science etc)

Thanks for the info Zeeforce. I would be interested to see some actual results from a UOA as well.

Dynamicperf, does this company plan on making drop in filters or any other type?

 

Here are filtration evaluations. I'll see if I can get additional tests and efficiency results from the ISO 5011.



ZeeForce

I'm sure the guys would provide a test sample. Dyson has recommended looking at these filters quite often. I would personally like to see this evaluation conducted.

 

White, what's it say? My work machine is the Hitler of the computer world. won't let me do anything.

 

This is what the first one says.



"R2C tested engine air filters from multiple manufacturers to establish comparative data for the R2C manufactured product.
Each filter was identical in size. With the exception of the R2C filter, which was manufactured by R2C using normal production materials and methods of construction, the individual filters were obtained on the open market and were tested to the exact same standards in order to establish the following performance characteristics:

1. Initial efficiency.
2. Initial filter restriction.
3. Cumulative efficiency.
4. Dust holding capacity.

The following equipment and test protocol was used to establish the test results:
1. The tests were performed on a SAE J726 air filter test stand located in R2C’s test facility by a qualified R2C Laboratory Technician under the supervision of the Laboratory Supervisor and Engineering Manager.
2. Each filter was tested to the ISO 5011 air filter test standard using PTI Fine test dust. Each test was corrected for temperature, humidity and duct barometric pressure. The laboratory is in an environmentally stabilized facility.
3. Air flow for each test was 400 scfm. The dust feed rate was 0.028 grams/cubic foot of air flow.
4. Dust capacity was measured at a 10” wg increase in filter restriction above the initial restriction. Cumulative efficiency was also established at this point.

 

Here is the second one.

"Even though efficiency is reported as the percentage of dust a filter collects, true efficiency is more about what is allowed to pass through a filter rather than what is stopped by it. It is the dust passing through a filter that causes engine damage and premature wear and failure.

When looking at collection efficiency, it is easy to overlook the differences in the volume of dust going through a filter of 99% efficiency versus a filter that’s 99.5% efficient. The 0.5% difference seems insignificant until you realize that the 99% filter allows 2 times more dust to pass through than the 99.5% filter.

Following is a list of some of the popular filters that were tested and the increase in dust volumes they allow.

Filter Efficiency Multiples more dust pass through

R2C 99.7% 0

Green 93.6% 21.33 times more dust

AEM 97.5% 8.33 times more dust

K&N 95.6% 14.67 times more dust

Amsoil 98.5% 5 times more dust

Airaid 98.4% 5.33 times more dust

 

SO where does the JWT Popcharger sit in all this?

 

I use Dyson Labs as well for my UOA's. Terry mentioned your product long time ago and back then was still in testing I believe. Nice to start seeing some of those test results.

Going to take a wild stab on assuming your synthetic media is not nano, like the Donaldson's made for Amsoil.

I'd be interested in your product with my UOA's if a drop-in filter is produced. Currently running Amsoil's drop-in; oem stock air box and staying that way.

Thanks for chiming in here.

 

Sure it's close to K&N as both are cotton/oiled...

 

Thanks WalkerT.

If a drop in was produced and cost was reasonable I'd buy it for *****/giggles. I'm def. interested in seeing what the oil analysis would show vs Amsoil air filter.

 

+1

 

The information is interesting but I'd like to see independent testing beyond what R2C has done. Not to be too cynical, but I don't trust tests done by the manufacturers of the "winning" product. Also, it would be nice to see dyno results to back up the claims make by R2C for their "Maxxflow Intake" for the Z. Does it really flow that much better than other aftermarket intakes and does it really control heat better? And if it does, is it backed up by dyno testing?

It appears that R2C doesn't make a drop-in filter. That is something that I'd be interested in.

 

Sounds good, I would like to test one with Dyson on a UOA, do you have a powerflow air filter for the NISMO CAI?

The Amsoil paper EaAU replacement part # for the NISMO CAI is: EaAU3050

Amsoil Dimensions:

Product Style: Round Tapered
Base OD: 6"
Flange ID: 3"
Flange Length: 1.75"
Flange Type: Center
Media Height: 5"
Top OD: 5"

 

I hope, for the good of all, that this actually happens
