The velocity stack i just purchased to mate with the end of the filter

I believe that large filter is going to have the opposite result from what you seem to be going for. By increasing the total filter area on the sides, the velocity of the air going through the filter media will be very low. If you cut a hole in the end for a velocity stack, there won't be much pressure delta left to pull air through it. If you also cover that velocity stack with some sort of filter media, then it would need to have lots of pleats, in order to compete with all the pleats in the main part of the filter. Basically, if the main part of the filter has 1000 sq. inches of filter media, then you add 10 sq. inches of media to a velocity stack , you've only increased the filter media area by 1%. You would wind up having about 1% of the total air flowing through the velocity stack.

The other thing I think you might be losing is the benefit of a longer intake tube. Your intake tube looks like it might be in between short enough and long enough.(no-man's land).

 

I am no professional when it comes to filters and how they work 100% but I think you put this in a way i can understand it so i am going to try and relay this back to you and let me know if i caught it lol.

So The closer you get to the actual intake tube the "suction" will increase. So the further away you get to the end of the filter the less suction you will have. So when i cut a hole in the top of the filter (where there is very little suction) i might not see any kind of performance gain... You don't think my headlight scoop will be able to "ram" enough air into the top of the filter to make any kind of a difference at speed?

My car is NA and to be honest going from the short filter to this one i feel nothing different (other than sound), not saying it hasn't changed but i am thinking its very minimal?

Thank you for the info, please reply!

Edit:
Reading over your comment again i see you are more focused on the amount of surface area and the fact that the top of the filter is considerably smaller than the rest of the filter. So if I use a smaller length filter that would technically increase the percentage of the top being used. Im thinking the "suction" would be greater as well... but with just a 5.5" difference in length?

What kind of HP loss are you thinking about exactly?

This thread below shows a total of 3-10 HP difference with 5" tube increase, unless i am reading the graph incorrectly...

Haven't read all the way thru this.but for the inspection issue you could run a bixenon thru the projector on both sides right? Or drill into the lowbeam side near the lowbeam and projector and fit a bulb to call your highbeam. Just thoughts to play with.

Also for the hole thru the headlight lens since most make it bigger and seem to use the hole from the factory cut for the hi beam correct?, could use a section of megaphone pipe from a motorcycle shop.cut the sizing to fit and then have it powdercoated the color of choice and use universal weather stripping to seal it with some silicone as well maybe?

I plan to fond a full spare set of headlights for a decent/cheaper price and doing one on each side.one for the intake filter and the other for ducting like evasive has going to the underside of the intake Mani.

Also thinking of using plastic or metal chicken wire behind each hole and on the manifold end of the duct to prevent most bigger trash and debris..anyone else think foam would be to thick to use to filter the duct any?

Sorry I'm typing my thoughts hoping to help job brains and make these work for anyone who is curious

 

It's not that I'm saying the longer filter will necessarily cost you power. My point is that the intake air will be pulled in through the path of least resistance. If you cover the velocity stack with the exact same filter material used by K&N, then the percentage of intake air flowing through the velocity stack will be equal to the percentage of total filter media area that is on the velocity stack. If the media on the velocity stack gets dirty faster than the rest of the filter media, then that percentage will drop over time.

I don't remember how large your headlight cutout is (diameter), but if it's at least the same size as the throttle body, then I'd try to impliment a system that draws air ONLY from the headlight. I would put the filter in a nearly sealed chamber behind the headlight with a small hole in the bottom to allow water to drain out. Then I would make the piping back to the throttle body as long as possible.

 

So like a PRM intake?

Yes lol

 

I really appreciate you sharing your knowledge!

From a performance stand point my filter setup now vs a PRM with a headlight scoop probably isn't to much different, i just get all my air from my bumper scoop. If i were to add the headlight scoop to the equation i am hoping its pretty damn close to the same performance, id be getting air from 2 different locations probably more from the bumper scoop. Im not really set on the filter material i plan on using for the top of the K&N, i was thinking about using a fine stainless screen, which would keep a lot of the nasties out although it wouldn't filter as much as the K&N letting more air in. Hell i could always tape off a section of the filter and see if that makes any difference.
