Airbox Idea
« on: June 25, 2011, 01:47:03 PM »
I have been following the ANTI-Pod thread and have had a couple thoughts.

First of all Kudos, GREAT WORK!

has anyone ever tried to calculate the airflow restriction of a stock filter/box setup and recreate that in a custom setup that eliminated the box?

My idea at current is to take a MAF sensor from one of my limousine and make an adapter for the CB550 airbox.  This way I could get a gallons of air/second reading at idle, part throttle, and WOT.  Since the town cars ECU also measure throttle position I thought it would keep the test accurate.  Then after constructing a new slimmer airbox I could set it up to the town car and measure readings.  This way I could try and make a custom filter that would retain the same amount of airflow as a stock setup, lessening the need for re-jetting and hopefully allowing for clip position adjustments only (hopeful I know).  I know that velocity stack shape plays a large roll in reducing turbulence and I plan to incorporate them into my design.

Does anyone have any suggestions?

Anyone care to point of some obvious pitfalls to this idea?

Any thoughts are welcome

this has probably been written in a number of posts but I'll toss it in anyway.

Back in the late '70s  it was the "hot setup"  to use the air box but make two modifications to it:  remove the lower lip  and drill a bunch of holes in the rear of the lower half.

I had a totally box stock bike at the time.  Doing this mod flowed enough extra air that I had to increase the main jet size from 105 to 115 just to get it to run the same.

the only down side was that the whole unit makes a fair amount of additional noise, long gotten used to.

Im not looking to increase airflow.

I am looking to make a completely custom setup, similar to Tintops ANTIPOD, but retain stock airflow
