and I came across a page with "ram air" or velocity stack diagrams on it, kinky... me thinky.
So here is a problem for me, my K&N cone doesnt have any sort of flare inside of it to aid in sucking the air up through the intake tube. Actually the intake tube is just a straight pipe that extends into the cone. NOT GOOD, so now I'm thinking, how the hell can I affix a velocity stack to the end of the intake pipe.
For starters I was looking at this

Its a $12 3" diameter subwoofer enclosure port tube with flares at either end. So if UrS4 has had some very good results with adding a velocity stack to a STOCK airbox, why not transfer the same logic over to the K&N cone?
Also was thinking, if the MAF on the AFC engine, is a heated wire type, then what would happen if we altered the amperage or voltage available to it. Isnt the thing based on the principle that the coils will reach a certain temp, and it calculates the volume of the air depending on the resistance to maintain its given temperature presented by the air passing over it, also it calculates the density of the air too by that means right? Or am I confused again.
So I was thinking if we reduced the power supplied to the sensor it would be possible to alter the flow that it tells the computer.
As I understand it, the AFC uses a frequency rather than a voltage output on the MAF. So the only other way to alter what the computer reads from the MAF is to record the frequencies sent by the MAF to the MMS-411 ecu and then program a device to mimic the output of the MAF, or to alter the frequency so that the actual MAF reading is not being recieved by the ECU, but rather a programmed reading.
I dunno I'm just pondering. After I spoke with Ron Skeene last night, I've been working out what can give me control over the Air/fuel mixture and timing.
