Desnorkel vs Cold Air Intake

How'd I do? Did I accurately match the tone of your post? ;-)

Yes and no. I have never made a 1.8 Fiat engine that could wind to 9k nor do I aspire to. From your original post it seemed that you may not have known much about the design of the intake. To me, making significant changes to the intake, just to make a better sound without consideration to the purpose of the design could be a mistake. I wanted to make it clear that there is a purpose for the "weird warty thing" you didn't know about - pass on some of what I have learned.



In answer to your original question:

... Can anyone comment? I'm interested only in the sound, for now.

My snide response for the day - How about an Android app and some good speakers?

Hahaha...I just bought the app for iOS 11, damn it is not working (screen freeze), not sure if it is a scam
But yeah, it would be a helluva fun to run my Boxster, with a Prius, Fiat Cinquecento or VW 1300 Sound. Gotta get in contact with the dev. Thanks for the great find.

y'al are awesome. Thanks for all the replies. ALL of them!
So here's where I should clarify some things:
It's not that I'm not interested in power... I am. This is why I'm interested in any REAL power losses that have been experienced. JFP's reasoning is very sound, but the practical application of theory is not always noticeable. That's why I was looking for something quantifiable, or even an "I installed xyz and felt a noticeable seat-of-the-pants drop...." sort of anecdotal evidence.

What I'm finding is that y'all don't seem to trust the ability of the aftermarket setups to insulate / isolate the warm air from the intake. It makes sense, of course. Though I have a setup like it on another vehicle which is actually QUITE effective, and seals tightly against the hood. But that's a front-engine V8.... very differnt situation. If the setup can't keep warm air out of the intake, then it's a step backwards. If it can't insulate the engine sound from the intake sound, then it's even a step backwards in sound, (for my tastes).

But maybe the hyperbole can that JFP described in his post is a place I can start, as well as replacing the filter with a less-restrictive one.

I am not a newcomer to making power, or modifying vehicles, or racing them. I Am a newb when it comes to Porsches, and mid-engine cars in general. So I'm approaching this as being interested in learning what y'all know. No sense reinventing a wheel that's already going. That's much better than me coming in and acting like I know everything, right? BUT: I'd like to understand it and weigh it against the knowledge I've already got under my belt. I'm not a guy who'll ever just buy and install a product (or worse yet: leave one intact) just because somebody else says I should. That'll ALWAYS be followed-up with a "WHY?"

And to be clear: I"m a smart-ass at heart. I like it when someone sends me a reply like the on below by cb350 (or whatever) because I can put on my smart-ass hat, and not feel bad. :-) I also assume others are not mean.... so no harm where none's taken, right?

Hyperbole? We have had the pleasure to work on a couple of the GT Cup cars over the years, and interestingly, they run the stock OEM air filters, not aftermarket air filters or cold air packages. When asked why, we were told point blank: They didn't add anything performance wise, just more intake noise. No low restriction or oiled filters, just the plain old OEM paper filters. And believe me, these guys analyze absolutely every part on the car, only use what makes it faster.

A few years back, we had the opportunity to watch a series of dyno pulls on a 986 that was trying out a bunch of things, ranging from different cold air intakes, intake modifications, and filters; to aftermarket exhaust systems. And while some of these products added more noise, none of them made any measurable or repeatable power increases. So unless you are counting the weight lost from your wallet by purchasing this stuff, there ain't much to be had.

If you are out to make the car louder, fine; just don't expect real performance jumps.

Sorry JFP, my phone changed helmholz to hyperbole. It changed it to hemorrhoid in another post, so.... Hahaha.

No, I appreciate all of your responses and help. You've obviously got a great deal of experience with these cars, and your willingness to share is fantastic. Thank you.

Not a problem, I have the same problem with the spell checker on my phone......

Maytag, you don't know the half of it. JFP has provided more guidance and support to 986 owners here than you can imagine. He is always straight forward and honest with what he says and you can ignore his advise at your own peril. He has helped me with everything ranging from spark plugs to transaxle fluid and cooling systems, all within this forum.

absolutely. Thats the benefit of these types of forums: guys like JFP. And so many others, even those who've tried and failed, and shared what they've learned.
As I get more experience with this car, I'll hope to be able to contribute as well.... from both the "here's what I know" and the "here's what I tried and failed" perspectives.

and that sent me down the Craigslist rabbit hole looking for a CB 350 Four to buy or 550, or 750. I love those old 70s Honda Fours and its coming back to the season for a bike. Nothing local, but I found this on eBay:



For you: Cut out the resonator or do the Pedro mod, and get the filter suggested by Bran. With the happy sound, you won't likely miss the HP/Torque from the resonator. Plan for a 550 SE or 987 airbox in your future with a tune and larger throttle body.
Look for stuff like this on the forum:
987 v 986 Air box
Intake plenum and 911 throttle body
Bang for Buck Mod

Lots of different personalities and communication styles on this forum. Now, go here and tell me what "maytag" is about? What's the story behind your forum name?

A man after my own tastes. I spent a season racing an RD400 in vintage classes... what a nasty fun little beast. Power was insane... And the throttle was a light switch. Those old CB's were bullet proof and would do anything.

I think you're on the right path for me, for this intake sound I'm looking for. I need to put my eyes on the helmholz that JFP is talking about and device on that too.

Thanks again y'all!
