My experiment with additional snorkel
 

Hello,

I've tried additional snorkel after removing main resonator. Also the sound generator has been removed.

The initial impression was very weak bottom torque. But engine sound was slightly increased like CAI.

As you know, main resonator contributes to low-end torque. So this is second trial with a plastic bottle. :D Don't worry, it is heat-resistant PET.

Low-end torque came back (but not 100%) and sound was kept. Drivability is much better than the first trial.

I remember that @Kodename47 would like to try this kind of thing in http://www.ft86club.com/forums/showp...&postcount=295. I wonder he did it or not.

Regards,

Could you just be adding in turbulence to everything?

Is that really a gatorade bottle?

Holy shit that is a gatorade bottle, its clear some of the civic kids are buying 86s now.

Is this for real

wat

:suicide: really.

Dont be an ass.. He trying different things, using easy to find items that fit..
Would you rather spends hundreds of dollars on a nice looking plastic piece that didn't perform? I think many are interested in seeing the results of these homemade tests.
Kudos to the OP.. thanks for sharing..

I've had 3 Civics, two of which were stock looking and boosted - and the other bone stock, so you are like a car racist.

You forgot to post the before and after dyno sheets. Without them you really couldn't have any idea what effect (if any) these changes made to anything other than the intake sound.

I'm sure that you thought you felt real differences but it's actually just the placebo effect.

I see your point.

Surely full load output should be important to this kind of mod. The stock setup is just two rivet holes away, so I can easily restore to the stock state and have dyno sessions to make evidence for improvement. But you know that it takes some time and money. I could make some data log using Torque app rather than doing dyno tests.

Anyway, 3rd gear 80-120kph compared to the stock 86 was almost same. So at least rpm band used that test wasn't badly affected, maybe.

But the torque decrease in bottom-end could be felt easily when you just release a clutch pedal to launch a car. Another problem is that dyno tests cannot show part load outputs. Real life drivability is relied on the partial throttle region as I think.

I know the possible collision inside the dirty side of the air box.
I have thought adding an air guide to separate two inlets.
Currently air may collide freely. :D

The gatorade bottle mod reminds me of a 'water hammer arrestor' used in plumbing to smooth flow in relation to valves slamming open and shut. Considering that long-tube exhaust headers improve low end torque by smoothing air flow ... It's beyond my competence to speculate further.

What could be happening is that air is going in through the stock snorkel and out through your added snorkel. The air wants to go where there is the least resistance, so it might be easier to go down the piping than through the filter and into the throttle body.

I just feel like there's a reason why no one has done this before.
