I can't figure out how to remove the blinds w/out breaking it. I see it has little snaps.


I have no clue what to do. Neither of the guides really explain how to do it.

Probably a dumb question, but just want to confirm that you only need to de-snorkel on driver's side???

Thanks in advance,

Jeff

Jeff, correct, the passanger side vents are for cooling.

I got to the "Pull out the tube" and mine just does not want to come out. I pulled and shaked that thing until I was afraid I was going to break something.

What gives?

2002 986S

Jeff

I had the same issue, I pulled and shook it and it just wouldn't budge. I was pulling pretty hard and I was afraid I was going to rip something out. After three trials I went on the net got some encouragement and once again went and pulled it as hard as I could, it finally came out after a while.

Anyone got an idea about how to remove the blinds?

Can't wait to see the results.
When are you planning to do this?

I desnorkeled my Boxster S yesterday. I had the same issue with it not wanting to come out. I pulled really hard several times and it wouldn't budge. I was afraid of breaking something. Then I tried twisting and pulling. You can't twist much due to the very tight space but it finally came out.

I really hope this is worth it because it will no doubt be a pain in the ass to put it back in.

I agree the air temp arguement doesn't really make sense. There is no heat source in that small vent cavity to warm up the air flowing in. How much difference could that snorkel tube really make in air temp? Besides, does the car not work perfectly fine in Florida or SoCal when the outside temps are very high, and in the Mid West and Northeast when the temps are very low? The enigine is computerized and designed to function and compensate at a wide temperature range.

I think that Snorkel has more to do with accelerating or focusing the air flow to the airbox. I'd like to know more about the aerodynamic design of that Snorkel.

hey bisi,

did you get around to dyno testing the K & N air filter? Or has anybody else seen a dyno test for the K & N air filter?

If the filter added 5 hp and the de snorkel added 5 hp , 10 hp would be a nice gain and maybe even a more little fuel economy.

ok I just did the snorkel mod.

My girlfriend was convinced that it wouldnt add any sound to the car.

Afterwards she was proven wrong!!!!

She admits the car does sound admirably louder. And if you look at the snorkel from where the air enters it, that cup blocks 30-40% of the air coming straight in , the air would have to go up and over the cup, also the snorkel iteself ovbiously takes up space in the intake tube, so that would be less air in there, which would equate less horsepower.

I did the modification to my 99' Box and I am quite impressed. It is noticeably louder after 3k RPM. It does have more pickup after the modification; at least that's my experience.

This website has a very good "how to" de-snorkel:

A couple of points:
1) When removing the snorkel I grabbed it and gave a quick hard yank, it came out immediately.

2) Make sure you push on the slats in the correct locations. That was the hardest part for me.

I've seen the tray that you mentioned on a 97 model, but my snorkel doesn't have a tray at the end. I would imagine cars without the tray wouldn't benefit as much from a desnork for the reasons you mentioned above. Does anyone know when they did away with the tray? My guess would be 03, but I'm not certain. :confused:

Porschephiles and critics agree, Desnorklefy your Porsche!!!

Bisimoto thanks for this tread, wil de snorkel mine.
Hope I can do it and totall un mechanical

Thanks
 

Bismoto thanks for the info. I desnoked my 2.7 a while ago & definately felt a slight diffeerence.

Looking forwrad to your reports on K&N filter & anything else you might cook up.

Congrats

@ Bisimoto, do you think any gain would be had on desnorkeling a 03 or 04 boxster that lacks the "shovel" at the end of the snorkel? If so, do you think it would be a less significant gain? Also, did you get the results in on the K&N filter?

If any 2003 or 2004 owners out there have desnorked I'd like to hear your opinions as well. Thanks!

Bisimoto
 

Keep up the good work. Its amazing how many people replied without any dyno of their own to show different results... All theory!

I am having trouble with allowing enough air in a cold air box setup using a K&N filter. The car a 3.4 ltr Boxster can't produce any power above 4000 rpm with the air filter but its goes like a rocket with the air filter removed.

I have been asking K&N for assistance with no response from Tech department.

I have 3.5 inch tubing from the TB to the approximate former location of the stock air box that has been replaced with an aluminium shaped cold air intake drawing air from the side vent. The filter I have is cone shaped with a filter on the sides and at the end of the cone rather than having a typical end cap. RX something as I am on vacation and don't have the number with me.

I am looking for a filter that will allow enough air to the motor 3.4 ltr headers and free flow exhaust system.

Thanks

Wtf?
 

Hey I know that they are kinda new in the Porsche world, but they are making a lot of waves and I'm sure the quality is just as good as K&N. There is a company called Evolution Motorsports and I'll almost bet my left nut that those guys could help you out on that whole intake problem that you have. Besides, my buddy owns EBS and he said that the best filters for the 986's are dry element because the MAF sensor is a little touchy. ;)

BUMP! Intereresting read....

Semi-snorkled
 

I desnorkled my car, but did not like the looks of the resulting profile from an air flow standpoint. If you have studied fluid mechanics, it is well known that the pressure drop from an inlet nozzle is much less if the nozzle projects into the stationary air flow.

So, I cut my snorkle off a few inches out and re-attached it:

I have my graduate degree in fluid mechanics and have worked in airflow management for twelve years up to and including today. I have no idea what you're talking about with respect to this geometry.

I also don't understand what your trying to say?

On another note, when running individual throttle bodies, the trumpet tends to be smoothed out at the end like a flower. That is because the air is pulled in mostly from behind the entrance of the throttle body intake. Is this what you mean?
