O2 modifier - VERY HAPPY

[Campverdefela]

I actually had the KewlMetal intake (sold it on this web site) didn't like the noise and the Green filter seemed to provide the same or better performance. The Kewl Metal set-up eliminates the "Velosity stacks" built into the air box, thus making performance gains suspect.:doorag:

Not quite, reduces them by about half an inch or so.

I'll ask again, Has anyone used the O2 modifier on a 2010 RT yet ?

It is not made for the RT. I don't know if it could be adapted, but if it could, it would likely take two, since the RT has two O2 sensors.

Now the weather cooled off a bit ... I am cruising between 2 to 3 bars (with O2 and MAD).

That may not be good as you are not really getting up to the "normal operating temperature" that this engine was designed to operate at. :dontknow:

 

[Big Bird]

finally got one. Low end performance is way up. Idles MUCH smoother and steadier. Excellerates MUCH smoother and stronger. AND no more popping on decel. Really feels like a different engine!

Highly recommended by me

THANKS TO EVOLUZIONE

Make that a Ditto for me!!! Glenn as Big Bird:clap:

1-2 bars

Right now I'm only seeing 2 bars at speed while around 40 outside and between 1-2 when in the 30's :dontknow:. Stock engine and still gets to 5 bars at stop lights.

Sounds like your thermostat may be stuck open.

Yea I thought that too. My first winter with the Spyder and not sure what was normal. I will have it looked at when they do the DPS update.

Nancy's RS runs 2-3 bars at speed in cold weather. You can watch it go up and down there, so I am certain her thermostat opens right about at the 2-3 junction...probably a little way into 3. Yours is worth checking. If it does not run poorly, I would not worry much about it, though...unless your state has emissions testing.

:agree:

Less than 60 degrees outside and mine stays at 2 bars until I slow down to less than 50 or so. It may climb some then, but goes back down quickly once it gets clean air. Probably nothing to worry about.

I've just recently dropped to two bars intermittently when in the low 50's. One other thing I have noticed with the MAD is that I could be running at 3 bars and then go in the opposite direction causing the number of bars to increase. So, the MAD and the cooling set up are wind directional sensitive; either more or less air is being pushed through based on the direction you are riding. I know this isn't earth shattering; but, just thought I'd throw it out there.

I know you've said this before and their was some previous discussion concerning this issue, but what proof does anyone have? Mine is that I differently am pulling a lot more air in with it, I know this because when I added the intake with just having the Hindle I had to add the JB and the 02mod because I was running way to lean. I would really like some opinions on this subject.

ISCI had their Spyder at Daytona Speedway for Biketoberfest, and had a prototype fan shroud on it behind the radiator. Jeff was ryding it, and was only wearing Crocs the entire time. They had a temp gauge hooked up at the point where the coolant would be the hottest for testing, and it never went above 210 degrees. It actually forces the air out underneath the Spyder instead of attempting to blow it out the side hole, and appears to be very effective. This might be a good thing to keep your eyes open for. :thumbup:

Also very happy with o 2 mod.No more backfiring on decel and my idle is less erratic.:clap:

The "Green" filter will flow about 2x the air the factory filter will deliver, while providing excellent particle filtration. At max RPM's the Green filter should deliver all the air the engine can ingest. Eliminating or altering the velosity stack tuning ( in the factory box) is a negative performance gain and a positive noise gain. I think the "Magic Man" has some flow data on the Green filter that may be of of interest to you. I think some real performance gains could be realized with the introduction of cooler air at the intake of the factory box with a high flow air filter. IMHO

I don't dispute that the Green filters performance which can be backed up with proof but where's the proof that the Kewlmetal's intake has a negative effect on performance. Speculation is one thing.

That is something you will just have to decide for yourself. There is good information available (research) on fuel/air tuning, velosity stacks & effects there of. The KewlMetal filter will no doubt increase flow over the stock set-up; However it does also tinker with the fuel/air tuning of the engine. The velosity stacks were designed into the air box for a reason.:doorag:

Yes but that's the idea, the stacks work in conjunction with the big box, while the aftermarket intakes out their have no box, different animal. Again I'm asking anyone out their for proof....

Proof??

Maybe you will just have to prove it yourself (one way or the other) through your own research.:doorag:

Your the one that first make the negative comment about the Kelwmetal setup without proof, if your going to say it then back it up.
