home made spiral air intake - Page 2 - PeachParts Mercedes-Benz Forum

My experince with product is fine.I blow excess oil off filter and clean my maf or mas 2 weeks after new filter change just in case.I've been using product for years in different vehicles.Never once was anything coated with dust.

if a spiral intake was such bad science,then why would mercedes benz design their vehicles as such?

i put my stock airbox and filter on just to see if i was indeed fooling myself. Gues wat. I wasnt. Big difference in throttle response and power. U can hear and feel when that thing starts spinning. Car rumbles forward aggressively

Thats probably because the wind ur creating is adding a little bit of pressure to the Kjet air meter plate causing the engine to run rich. You're not making any more power. You're just burning more fuel. Get a WBO2 gauge setup.

Out of my own experience the m110 filter setup sucks and I did gain when I ran a similar pipe to what the op is doing. I still don't think the spiral thing helps but an m110 will breath better on the setup he has now.

The fact that you guys are actually taking this whole thing seriously is disturbing. The thing is a block to the intake, and even putting the thing on the side doesn't actually do anything, you're still blocked by the fact the 100mm tube is the most the air will flow regardless of how many little turbine outcroppings you've got. With as many turns as the air flow still has to course through to get to the intake valve, I'd be really surprised if any of the tumble induced, or remaining in the air intake charge came from the little spinny-do-dad. Let's think about this for a quick second, the air sucked into the intake tract would not normally be swirling, lest you're in the wizard of oz or some other extenuating circumstance. Thus, physics says that air that isn't spinning wont want to spin, unless energy is put into the equation. You're adding no energy. This means that energy has to come from somewhere. Since I'm assuming you drive around with the hood closed, that rules out solar energy, and since you don't mention anything of a giant fireball in the intake tract, I'll rule out chemical/thermal energy. What's that leave us? The only energy drawing air in is the vacuum created by the piston going down in the cylinder, creating a vacuum. Aside from Hemholtz resonances and pressure fronts created in a vary narrow rpm range by the sudden closing of the valves, that's all you've got to deal with. Now to spend some of the energy you're now using to draw in the air to instead spin the air way up the intake tract where the spinny air probably wont even be spinning by the time it makes it to the intake valve, how can you plan to improve power with less available force to move the air into the cylinder?

Since we've already put electric superchargers to rest, and now vortex thingys, here's a good popular mechanics link so we can put all the hair brained schemes out of the way:

you dont make sense, can you explain that a bit better?

Hmm.What about the Chevy tricks ram air and cowl induction.

you said " a little bit of pressure" that was the objective

maybe mercedes benz should have thought about this when they routed the crankcase breather into the air intake

The German Gods were stupid about that.That why I vent my nasty blowby away from intake track.

They were far from "stupid" as they had to meet USA EPA standards to get the engine certified.

You do recall at one time ( pre EPA emissions standards ) engines used a road draft tube which was no more then a pipe from the crankcase to a lower part of the engine....

If you have "nasty" blowby on a normally aspirated engine then your engine has a problem....

I think the point is that a fan does not compress air.
It is not able to generate enough positive pressure to overcome the vacuum of the engine to create a measureable intake pressure increase.

A 1" thick throttle body spacer would achieve better results then the fan you install.

It's great to do "feel good" modifications, but unless you are able to prove an improvement over a baseline be it with a dyno, track results or 3 axis accelerometer, it's all in your mind....

Ed, don't dismiss the value of a good, accurate butt dyno!

Its the wind off the pistons
