WTF!!!??? I don't see anybody else having a problem with parallel threads. To me, It's good reading. And it shows we all have common interests on how we like to modify our bikes. The more information we get,the better. So Psyco, If you think I'm an ass, Thats fine. It don't bother me one bit.

Carbon Fiber Snorkel OK... I've been sitting on the sidelines watching the debate over the carbon fiber snorkel setup for a long time. Too long!! Time for me to stir the pot a little!
I hope no one's panties get all bunched up over my opinions on this. Nothing I say here is intended to flame anyone.
Here goes:
1) "Kawasaki designed the new 2002 to take on 30% more air."
No, I think it would be correct to say that the air inlet area is 30% larger. That does not mean the intake system will take in 30% more air, or that it is 30% more effective.
2) "It may not show on a dyno as there is no airflow."
It DOES show up on the dyno BECAUSE there is no airflow. You aren't "packing" air into the airbox as you would at speed, so opening up the intake so the engine can breath easier can increase horsepower on the dyno. You can also do this by propping up the gas tank and removing one or both of the throttle body inspection covers.
3) " KCadby's bike gained an extra 6hp over best yet after mapping the snorkel."
Same thing as in #2 above. Only difference here is that not only have you allowed the engine to breath easier on the dyno without ram air, but fuel delivery has also been increased via the Power Commander. Still doesn't tell you anything about how the ram air system will function in real world conditions.
4) "Doug was running in a modified production class (I think) and the bike had to appear stock on the outside. Notice the pipe looks stock too, there's no way in hell anyone would use the stock pipe on a bike at Bonne. I don't know how the snorkle COULDN'T work. Kawi could have made the ram air flow more and make more power but they also had to worry about intake noise. I know some people with cf aftermarket full ramair setups that flow way better than the stock stuff."
Doug ran in two classes (or more?) at Bonneville. In one class he ran in, the bike had to appear stock - but that's not the class he was running in when he ran 203-something. [I think that was the speed he ran for his record?] He was running in a different class and using a full Muzzy's exhaust system when he got his record runs. I don't know if that class would have allowed him to use a "monster snorkel" or not. Whether or not you make the ram air intake setup flow more is not the issue - making the ram air system develop higher pressure in the air box area between the air filters and the throttle bodies IS the issue.
5) "I got one and did top end tests before and after the install. 201 before, 201mph after. Same conditions."
There ya go! Tested with GPS - before and after. Shouldn't even need to tweek the fuel mapping on the Power Commander - if there is an increase in ram air pressure with the carbon fiber snorkel the pressure sensor in the air box will "see" it and "tell" the ECU to add fuel. Right??
6) "I don't think the [stock] system is restrictive at all, under any conditions. The opening in the front of the '00/'01 is good for about 350 hp. The positioning and shape couldn't be much better."
That's from Doug! I'd venture to guess he's looked into this quite a bit since he's always had a serious quest for higher and higher top speeds!
So, unless someone can ABSOLUTELY PROVE that there is an increase in performance on the 12R with this new carbon fiber snorkel thingie (and NOT on a dyno!) I'm going to have to chalk the limited positive testimony given up to something like "placebo effect". If you want the thing for looks then by all means get it! [Carbon fiber is to some sportbike riders what chrome is to the Harley guys.] If you're looking for some kind of real performance increase I think there are much better options. And YOU KNOW that 'ole RocketRacer is always right!!

Hey psycho, way to go! Now, just how much time do you have? A test with the stock inlet minus screens with the divider thinned down and the joints sealed with duct tape might be interesting. Also, I'm positive I read a post some where about Kawasaki wanting the snorkle 1" longer but the opinion was no one would like it. So a simple extension hot glued to the snorkle for a test. That would cover all the bases. The reason I brought this up is I've done the first and plan on doing the second. Hey, anybody with a Hans ram-air unit want to sell their stock snorkle?

this is frustrating... there are 2 snorkel threads.... everyone take it to one or the other! this one seems to be missing much of the comments AGAINST the snorkel... interesting...
I still think it's a fancy-nancy piece of CF that you'd buy just to pretty-up yer 12... there are many many better ways to mod yer 12 and get PROVEN results for the same $$$$ layout.
This CAN NOT be disputed... everyone here knows this.

Testing Soon! I like what Rocket Racer Had to say. I find his post revealing.. and probably not too far off, if at all. I, too, have been skeptical about spending the money on the Hans snorkel without any real data to go on.
I like Hondo. I will be searching for some real world results. My current stock snorkel does have the screens removed and I sealed the system from all leaks. I will be testing this setup on the dyno and also will be monitoring the static voltage readings from the intake pressure/vacuum sensor. Immediately following I will install the Hans carbon snorkel to do back-to-back testing. Of course, on the road tests will follow and I will compare voltage readings to the current stock configuration. I will know soon (a month or so) if the Hans was worth the expense.
Also, Rocket....On your top speed test (201-201) The difference the Hans might make at that speed (@6 h.p.) is probably not enough to make a difference due to the extreme resistence from the wind at that speed. I will be looking for any usable gains of power under peak.
Thank's to all who have contributed "useful" info to this post.

Dyno Test Day The day I will be testing the new Snorkel on the 250 Dyno is Feb 19th. I will post a new thread re; the info I obtain.

DYNO DAY !! This evening I will be doing the back to back test w/ the Hans snorkel on the DJ250. Today's weather is a wonderful 70 deg. w/ 50% humidity and the berometer at @ 29.95 in.
Of course this IS Phoenix !!
Stay Tuned !!

Crunching #'s Preliminary data (Voltage reading's) from the Intake pressure/vacumme sensor is POSITIVE from back to back runs w/ both the stock and the Hans snorkles. The Hans recorded HIGHER readings in the upper rpm's (8000 and^) which indicated less vacumme in a static enviroment, I.E. less restriction.....Also a real world power increase of 4 h.p. from 8000 to 11750 r.p.m. static.
I will post a new thread w/ actual #'s and what they covert to after I do the "ON ROAD" testing of the Hans this weekend.
