Dyno on G37 Stillen G3 vs. RC2

dainedazz · 08-26-2009, 06:01 PM

and can someone explain to me the pros & cons of Dry Filters vs. Oiled Filters.

jpit · 08-26-2009, 06:31 PM

Oiled filters use oil to help captured dust and dirt. You need to clean and re-oil them every so often. Apparently, if you use too much oil it can be fed into the intake and coat some of the sensors causing them to misread. Dry filters you can clean with a good shake and some low psi compressed air.

You forgot to mention that dry filters have a tendency to break apart and get sucked into the engine.

I would like to see a dyno sheet that shows below 3000rpm and shows torque too.
As i know with alot of these intakes you actually lose power in the very low rpm due to the initial suck of hot air from engine bay.

Hopefully this is not the case with the R2C due to the shield

the air filters is where it's mainly at. K&N are oiled filters and not everyone wants to clean and re oil....so that's out. r2c design and produce their own air filters....dry ones too.
these air filters are used in the U.S military, so they stand to dust very well and provide good airflow.
R2C is primary an air filter manufacture, they just made a small auto intake division now.

Clean and reoil what, every 50K? paper filters will need to be swapped at least twice in that time.

Here is an air filter test conducted by Bob the Oil Guy. His conclusion is that K&N filters allow more air flow than OEM or foam filters but also don't filter as well. He says that might be important.

the internets says this could happen if a paper filter gets soaked. R2C is a washable synthetic material filter.

btw, from a random internet search, NASCAR apparently uses dry filters:

K&N Releases Air Filters for NASCAR Truck & Busch Series Racers

"NASCAR rules require air filters in order to race. K&N's new 2-ply cotton un-oiled filters meet NASCAR requirements. "The 2-ply cotton works the same as our 4-ply," said Maier. "It just allows more air to flow."

I would also like to see this... I would think that the heat sheilds would act similar to the stock airbox. Thus, you would not be sucking in any hotter air than the stock airbox intake setup.

FYI on RC2, they have a small division of their company that does EXHAUST filters for the mining industry! Their filters allow for the diesel engines on underground mining equipment to actually emit cleaner air from their exaust than is being sucked in on intake! There was a small 5min deal on this on the Discovery chanel where they were covering mining machines. They said that the mining company chose filtered diesel vehicles over electric for underground mining because they perform two functions, they act as a vehicle to do their main function, and their secondary function was air filtration. Diesel was chosen over gas because of some funky catalitic/amonia injection system that actually caused the exhaust the emit almost 0 CO2 as well (or some crazyness like that).

So RC2 has some good experience in all kinds of filtration.
