I have made only two performance enhancements to my Spyder and thats the Hindle exhaust and this K&n intake. After the Hindle install the ecu only compensated so far and I still experienced some backfires and sputters until I installed this intake and now it runs beautifully.I've been reading the post & replies about the KM air box repacement. I've beem a engine builder & tuner,for some years now. My concern is the removeing of the velocity stacks from intake. After doing much testing on dynoes, one thing we have learned is, 1, just cause it sounds louder dose'nt mean its making better performance, 2, seat of the pants rarely feels 4-5 hp changes. I have found that changing the length of the inlet runner length. V.E. calculation will change more then what a juice box or a stock ecu will be able to correct. It's might be possible to cut out the stock stacks an modify to fit the KM system, but might be restriced the total air mass that is now not surrounding the stacks. I hope to be able to shine some lite on this as soon as I can talk the bh, in to putting her spyder on the dyno. Her exact words " dyno your bikes, just leave my spyder alone":lecturef_smilie: Gene
I'M THINKING THAT PORT IN THE BASE PLATE WOULD WORK GREAT FOR A NITROUS FOGGER JET.
I just installed the KewlMetal air cleaner last weekend and I do not find the intake noise offensive. It reminds me of my younger days on my Super Sport when I'd flip the air cleaner cover to get the intake sound from the QuadraJet carb. I do like being able to see and work on the motor on the right side. That massive original air box made it difficult to work on. It seems to pull stronger but I think it is more the placebo effect.

After I added the Hindle, JB, and now the KewlMetal system I have always said that the performance was enhanced but that was only a seat of the pants evaluation. Today I talked my buddy, who owns a bone stock 09 SM5, to try a few trial runs with me in order to evaluate my performance against his. Reluctantly, he finally agreed, so we set up three trials one from a standing start to not over 70 mph. The second from 40 mph starting in 3rd gear to not over 80 mph. The third from 70 mph in 5th gear to as fast as you feel comfortable. I could easily take the stock Spyder in every attempt. The most noticeable was the 70 mph start in 5th gear; just literaly left him in the distance. So unless there is something wrong with his Spyder the performance mods do work and it is not just a false perception. BTW: We are within 5 lbs. of the same weight.
Thanks for the performance update information as well. That sounds like some pretty fair tests you ran, and there was obviously a noticeable difference. :thumbup:
Any more updates on the air cleaner? thanks
I loved my KewlMetal air intake---It performed better, looked better, but made more noise (didn't bother me I rather liked it) passenger complained said it roared in her helmet, go figure. So to keep passenger happy and riding went back to the "green" air filter.:shemademe_smilie:The KewlMetal filter is a very high quality product.nojoke

What is a V.E. calculation, and how does that calculation correlate with the capabilities of the JB and the ECU?:dontknow:
Just some questions that went through my mind as I was reading your post.

http://www.outerwearsracing.com/ try these instead of foam they breath better and easy to clean with no hp loss we use them on are mini sprint (1000 cc Kawasaki)Black Widow,
Glad you like it. I could not stand the stock air box mainly because it cluttered up my engine compartment, and next because it tended to get sand in it and the air filter seal was questionable. Now I know I have no sand getting past my filter. It's very dusty here in AZ and I am on a gravel driveway so I am going to add a foam wrap to mine.

I just got through adding some sound deadening material to the back side of the yoke pannel (the one that sets just above the air cleaner) to see if that would reduce the intake sounds from the KewlMetal air kit. The noise (which was never to loud) was substantially reduced and changed to a more mellow sound when accelerating. The material is a thin (approx. 1/8 inch thick) foil covered rubber like material that is sold for acoustical speaker cabinets and is self adhesive with a peel off back. Easy to apply and thin enough that it doesn't compromise the panel fit. Works good and easy to apply.:thumbup:

Hey Blackwidow,
Where did you get the deadening material? what brand? I really like the intake, but it sure is louder than the LeoVince exhaust I have... I also hope it doesn't affect my warranty...
thanks

I got something similar at Home Depot for about $12, it was duck wrap in a 10 or so foot roll foil/foam, sticky on one side and about a foot wide.Hey Blackwidow,

The material you are talking about is Dynamat, and its imitators.You can also get something similar through JCWhitney or any auto restoration/rebuild/hotrod catalog like Year One. People revisiting their youth are using it in the classic muscle cars for sound deadening. It seems as they have gotten older, they are finding they don't like all the noises those old beasts make.![]()
