Anyone have some pictures or a how to for the zip tie mod. Going to the track Thursday and wanted to experiment w/ it. Just wondering what tools to bring and how long it will take to swap out at the track.

 

It's really not worth doing.

 

It was the first mod that I did on my car, and I def think its worth doing. Here is one of many detailed threads.

i gained .2 and 2 mph at the track from the zip tie mod.

 

Guys ... whats the point of doing this ? Looks like the filter stays in and is not being changed to a different type of high-flow filter.

Is the purpose to tighten up the housing & prevent air-leaks ... ie, to generate a slight positive pressure of air to A.B. ?

 

O.k. first of all, It's very worth doing.
Second don't do it until you get yourself a K&N filter.
What I did is take the upper cover off completely, then bought 4 very long zip ties from a local store. Then I ran them under & over the housing & filter, pulled them real tight to make sure there is a positive seal.
That's it, you're done!
Double check your whole intake to make sure all fittings are nice & tight, because if there is air escaping the car feels like
Drive for about 3 days before the computer configures your new mod.
Dyno results usually yield anywhere from 8 to even 15 hp if done right.
Good luck

Yeah it's worth doing. And like KraZ says upgrade your filter though. Don't use the paper one. Also you should probably do the hood seal since rain and/or washing your car will dump water down the opening between your hood and the front clip. Forget the $20 hood seal rip off being sold. Just get some 3/4" black weather strip from HD. Cut 2 peices and stick it on. No more water leaking onto the filter area.

You can also butcher a spare Z06 cover like I did so the box is still secured and won't move around. If you're going to do just the zip tie mod consider taking some velcro. Attach one side of it at each end of the bottom breather assembly. Then the other peices to the top of the radiator shroud. Now push the box down so they meet. The box should not slide around under hard cornering. For drag racers it might not be a big deal but for road courses the box will not stay still as it is not secured.

 

Worked well for me. I'm still running the stock paper filter as it has better filtratration qualities over the K&N, but to each his own. I picked up 15RWHP and 11lb-ft rwtq with the Zip tie mod.

 

I am not trying to bash the mod or anyone who has done it...

I just personally don't understand why someone who can afford a Z06 would want to pop the hood and see something held together by zip-ties.

Once again, no disrespect intended.

 

The whole point of the Zip Tie Mod is just to open up the area of the filter, so it breaths better. A covered filter is more restrictive.

 

Because for some people this makes the diff between a 11sec car and a 12sec car, bone stock. I am at that point and just want the extra push to get my 11sec time slip bone stock. Of course, I'll end up spending the money for an intake but for now the zip tie mod is going to work just fine to give me the little extra needed. However, everyone that has a Z06 doesn't always have alot of money. I am 24 and bought the car for the love of it not because I needed a way to spend money. Just saying for some of us there is nothing wrong w/ saving some $$.

 

i'm still running the stock filter also. i have no regrets from doing the ziptie. great free mod.

 

I did a zip tie mod at first, then a freind sold his Z and gave me a smokin deal on a breathless intake

 

To hold us off until we get a real kickin' intake

 

I feel the same way! I am 23 and do not want to spend the extra money on an expensive mod. This mod however, will be my 2nd mod (1st is window tint that is being done tomorrow morning). I just got my 04 Z06 8 days ago and I can't wait to do a mod to it!!!!!!

 

Great explanation. Makes sense to me.

 

An paper filter generally flows more than a K&N filter. The gains normally come from more filtering area. The material itself is thicker/more resitant.

That is the dumbest quote,yet
The K&N kills the paper ones with alot better flow.

 

My point is why spend hundreds of dollars on an intake for 0hp gain?

As for the filtration. A K&N flows more because its a poorer filter. Its filtration qualities are poorer than a good paper filter. I use a stock paper filter, and I'm quite happy with it.

When your filters are the same size, the only way to allow more flow is to reduce the restriction. How do you reduce restiction? You increase the size of particulate matter that can bypass the filter.

On any filter the filter actually allows more trash through initially when it is clean. As it gets dirty, the dirst actually becomes a part of the filtration media as the particulate matter blinds off the pores in the media. So, right before a filter totally blinds off is its most efficient in terms of filtration, but its worst efficency as far as flow.

 

A paper filter is generally thicker than an aftermarket (K&N, S&B, GREEN, RUSH, etc) and has more total filtering media (which includes the surface area of all pleats) to pass dirty air through. That fact gives it good dirty air filtration (not necessarily better), but lesser air flow.
A thinner cotton gauze (ala K&N) or synthetic (ala BLACKWING) uses less media to pass dirty air through. But, the media is usually treated to trap the dirt and is very efficient at trapping the dirty air before it enters the motor. The thinner media allows more air to pass into the motor, which is a good thing from a performance standpoint. It also usually increases fuel economy and maybe hp to some degree.
You reduce the restriction by changing the media to a more efficient dirt trapping/air flowing product. If you're happy with paper filters, there is a willing market willing to sell to you, just as there is with aftermarket filters.
Would you rather wear a paper shirt or a cotton shirt?
The cost of the aftermarket filters is acceptable to most of us since the filter is reuseable. That above all else is why I use non oem filters in all of my vehicles. The mistake that users of both paper and aftermarket filters both commit is allowing the dirty filter to remain in place to long w/o replacement or cleaning. Cleaning/re-oiling is another issue all together.
