Default Flow oil filter?

Is anyone using the PC Racing Flow oil filter? Just curious 'cause I just ordered one.

American Iron did a test on that filter a while back and found some horse power on their dyno.I think it was about 6 horses. Check back issues.

It makes the oil happy and, as we all know, happy oil does a better job.

Ferrari uses a spin on type, throw away, filter. Not sure about 20,000 RPM F1 cars. Or F22 Raptors.

OSB, I thought the same thing.If I explain,the stock filter took a lot more pressure to flow the oil causing the oil pump to have way more resistance,thus taking power from the engine.They had the tests to show it.The bacic engine has to power outside things like AC,the charging system,water pump,fuel pump,smog pump,power steering pump and so on.So the less all these things take from the engines horse power ,the more power thats left at the crankshaft ,to turn your wheel or dyno.If I can find this old magizine I will post more.

I am not making this claim. American Iron is the one that said it.the PC racing company does not mention horse power that I know of. I think also as a side note the price has come down since the article was written.

Thanks for the input. Not sure about the HP thing but it should flow better. I'm interested in seeing what debris comes out when I clean it after running 3-5k miles. I'll let everyone know how it goes...

You know, now that I think about it, maybe a very small gain. I installed a 25% underdrive pully on my mustang that slows the rotation of the A/C compressor, water pump etc. putting more power to the rear wheels....Hmmmmm.

I run a similar filter produced by K&P Engineering. The horse power claim is derived by the fact that parasitic drag to the oil pump is reduced due to the filters ability to flow higher volume at lower pressure. Now, I don't know about any of that, and that's not why I run one. When you look at the 5 micron filter media of Harley's new filter, it seems obvious that the filter easily goes in to bypass when the oil is cold or rpm's are high. In other words, oil filter bypass means none of the oil is filtered. The micron rating on the permanent filters is larger, that's why they flow free'er. When you purchase a high flow filter, your filtering all the oil at higher micron rating, versus 5 micron filtering sometimes, and no filtering at other times... to each their own.
