Car guys....Air filter question

[CQBgopher]

Sadly, best spot for a presumed cold air intake WITHOUT creating much of a ram effect, is at the base of the windshield.
Those engineers in the sixties an seventies had it figured out!

Is that what they call cow inducing, or cowl inducing, something like that?

K&N's are a big waste of money. And they filter like shit. Hold one up to a light and look through all the holes.

Isn't that why the oil is there, to catch the grit?

Cowl induction...presumably there is an advantageous pressure zone at the base of the windshield. Sadly (my opinion only) that much like the rest of the other hood induction and ram induction attempts, im not sold on the "supercharging" effects these things claim to give.

Nothing scientific of course, as i dont have that type of time and money, but once you open them throttle plates physics or nature is doing all it can to stuff those cylinders. Volumetric efficiency has certainly improved over the years but i have yet to see a filter system that is supercharging

Yes the old gimmicks brought some nice cold air to the intake, as opposed to the nice hot underhood stuff, but if everything was tuned correctly the air/fuel ratio was the same most of the time. WOT or things that were tuned more for power than emissions or economy being the exception

Yes oil helps trap the particles that hit the gauze but i dont think it takes a scientific study to determine that gauze will pass a much larger micron size particle than most paper air filters

Cowl induction. Essentially, yes. But, still best positive air pressure at base where hood meets windshield, at least in old school cars where aerodynamics wasn't so prevalent.

I like turbos they are slightly better than cowl induction and ram air combined.

[toys in the toybox]

turbos are meh and have thier place. I think there are better and more cost effective forms of supercharging but to each thier own as others have more money than i do

My friend is pulling 1500+hp out of a honda/Acura 1.8l, it would never be able to make that with a supercharger. I've been in a couple of mustangs, one turbo the other s/c. Both cars dyno'd right around 625hp, but the turbo car just felt like it was packing a lot more power. It could be the tuning though too. Notice how in the last few years there are a lot more turbo cars in drag racing? I see more of a turning to turbos rather than super badgers.

[toys in the toybox]

dont forget nitrous!!! the turbo car probably felt like it did cause there was a seat of the pants boost pull. superchargers are more linear in power


N2O it does what the others do a lot cheaper and with a lot less crap

I suggest your buddies car could make the same hp with a charger. It comes down to blower cfm and drive ratio. There is a bit more parasitic loss but it could be done

All three do exactly the same thing

Isn't a supercharger just a turbo mounted up by the alternator spun by mechanical means, like a belt? The blowers are the big ones that sit on top, like a dragster right?


Is N2O the same as NOS?

[toys in the toybox]

all are blowers or "superchargers" wherever they are mounted regardless of drive method (belt, exhaust) but you know that

NOS is a brand (Nitrous Oxide Systems) N2O is the actual gas

satisfied yet???

Both are superchargers, the ones that sit on top are roots type superchargers.

And nos is just a brand name of an n2o system. Like Kleenex.

I'm still stuck on the whole K&N thing, really. They're made of gauze, like a band-aid?

What keeps an engine from just sucking all the oil right out of one?

Hope? Denial? Information found in a sales pitch?

[toys in the toybox]

well ideally its not dripping with oil just saturated and since they have lots of tiny holes the air comes in and not the oil. Mind you its not like an oil bath more like a dirt ping pong ball hitting the sticky oil before it passes thru the holes

Unless you have done something wrong there should not be enough vacuum on any given point to "suck" the oil out of the gauze, same for paper in the paper filters

[CQBgopher]

They have a 1,000,000 mile warranty. That's pretty impressive.
