MCM: Pod filters mythbusted

Opinions?

No surprise there. I was hoping to see an improvement with the oil panel filter though. Good post.

All about preference. If your running stock air box, filter has to be changed every oil change in order to be mint. Power intake never seen dirty.

INteresting..

Interesting post / test. Does not simulate the forced induction of air on the road / hiway speed. I believe that`s where higher quality filters and pod filters excel; and perhaps change the results of their test. IMO air intake with high quality filter vs. pod filter is really a matter of preference. I`m running the stock box, though like the idea of going pod to free up some room. Makes for good discussion.

saw this video the other week. as for intakes, this one is bad ass







Saw it in the Fab thread on zilvia. Shits legit.

Interesting.

One thing that test is missing is adjusting ECU tune to suit, as that is where the hp gains are the biggest. Also on the turbocharged car the A/F ratio is probably already lean due to chip, so adding podfilter made boost level rise and A/F ratio probably was too lean. Basically not adding fuel to match the increase in boost level probably would make hp drop.

Podfilter is supposed to increase boost level 0.1bar which leans out A/F ratio and that is where the extra hp comes from. It's not uncommon to see 8rwkw gains over factory with good podfilter on turbocharged engine with factory exhaust, etc (I think with bonnet up). With bonnet down power should drop due to higher intake temps (why factory use a airbox).

Note when ECU is tuned to suit aftermarket filter, there's a bigger gain in hp, but without ECU tune to suit there's minimal to no gain. Also note that when using a bigger filter element, more air enters engine and mixed with ECU tune to suit the engine produces the most hp.

Then look at Gibson Group-A 32GTR and you'll notice the same bigger filter element is used on top of top radiator support (same location) -



ECU tune plays a big role, so does intake temps, filter size, etc. If you look at filter test's you'll notice the bigger filters + ECU tune to suit produce more hp.

Given the fact that I have to richen jets up on motorcycles when I install pod filters for customers, yes... they DO something.

Here's the other one they did on Cold Air Intakes:

Interesting. I wonder if they will try bigger, smaller podfilters and before, after ECU tune to suit like the NA V8 test.
