Finally: Dyno charts of de-snorked 986S!!!

Bisimoto-

Welcome to the board and thank you. I think alot of us have been waiting for a true engineer and enthusiast to come along and do a few things right. Theres no doubt that the factory 3.2 is a somewhat detuned motor to keep the Porsche pecking order intact at the dealership, but it would seem that the key to coaxing more power out of the 3.2 lies in DME tuning, not just bolt on bits to help the motor breathe better.

I am very interested in finding the right headers (preferably with integral high flow (200 cell ideally) cats and 2nd cat deletes. On a motor of this expense, I'm not sure I trust running any of the higher flow filters or intakes due to the increased amount of grit that gets by, by figure a de-snorked stock intake. Now if someone can make a fantastic map to flash into the DME to take advantage of this and 93 octane fuel (or better) I think that would be a real winner.

Good luck to you and keep us posted.

I just looked on caymanclub.com for desnorking.

I'm still not sure what it is. All I got is that there is an extra air restriction on the car somewhere.


Can anyone explain what it is briefly?

[Bavarian Motorist]

Never mind, guys. I found an amazing guide here.

This guy has a Boxster S 987 so this applies directly to us.


I will not even bother putting a wire mesh because I don't smoke and no one who drives my car will smoke.



Thank you, Bisimoto, for bringing this great idea to my attention, and most of all, thanks for proving that it is worth it

The mesh will also help keep "leaves" out and other stuff that flies up from the road like other peoples cigaret buds.

He accually removed a restrictor plate thats in front of the intake.

Oh yes, that too. But left the snorkle on the 987.

Now I am confused. So there is a snorkel somewhere also? Do you know where it is?

How come the 986 doesn't have this restrictor plate in front of it to begin with and the 987 does?

Not worth the 2 dollars to me!!!


Just kidding.

Now where are all the critical comments from forum members who have said emphatically that desnorkeling will not increase HP at all and it's all about making the intake a little louder?

Lurking now, aren't you?

When people always referred to "de-snorkle" I thought they were talking about the intake tube that contains the little extra noise/silencer box that sticks out from the tube just before the throtle body. I had no idea there was another "snorkle" shaped device in front of the air box, that one could remove fronm the outside. I think many others were thinking of the C.A.I. tubbing also. I'm deffinately going to remove this "snorkle" part now.

Hi,

Just caught this thread - see: http://www.pca.org/tech/tech_qa_question.asp?id={5628EC8F-3626-40D2-8AE0-E9F524E0718F} . I'm still not totally convinced, I think there's an error in the methodology. That's an approx. 6 CHP gain, and I'm just not convinced this part robs 6 HP. I can hold a thermometer in my hand and watch the Mercury rise, that doesn't mean I've made the room any warmer, or conversely, that I have cooled the room when I release the thermometer. There's no reason for Porsche to do it...

Happy Motoring!... Jim'99
