This was posted awhile back on the old site. I almost got one. I can't remember if anyone ever did, or if they really work. Weapon R is a pretty good name though.

i was also thinking of getting one but i asked my self how much faster will i actually be able to floor it.. lol.. cuz i doubt with that on there i would notice anything of a difference for my car i don't feel a need for that.

Simply a more lightweight butterfly, doubt it will really help that much. I never hear of racers goin "man if only my butterfly were more lightweight!!" LOL

Its not the butterfly.

It changes the pivot center and rotation, thus allowing the throttle plate to be opened faster. Meaning you have to apply less throttle to the pedal, for it to actually throttle the engine. Gives it an illusion of a low end power increase, but it is simply revving the motor more, with less pedal effort.

yea but i think the question is ... is it worth spending the money to be able to push a pedal down a little bit less in order to get your engine to be at full throttle than normal... ?... at least thats how i see it ... i guess it would be who could push down their pedal faster when it comes to a race between equal cars... lol.. IMO.

This is not worth it. This may actually hinder your drviability.

Explanation: Do you have trouble getting your throttle to WOT? if not, then why shorten your pedal travel? This is all hype. The only way this would be useful is if when you put your pedal to the floor, is if your throttle butterfly does not open to WOT (Wide Open Throttle). This is a throttle rotor, meaning it is the piece that attaches to the rod that is connected to your butterfly. By making a smaller throttle rotor, you are just making your throttle go to WOT sooner in your pedal travel.

As for drivability: Having more control over your throttle position is key to driving your car to its maximum potential. Any racer will tell you that you cant just mash the throttle and expect the best response. Smooth transitions on and off throttle and on and off braking is the key to faster response from your vehicle. Go ask any autocrosser that is good. They will tell you that smooth application of throttle will yeild better response from your car. So would opening your throttle to WOT a millisecond faster be good for performance? No. This would also affect drivability in the snow, where throttle control is CRUCIAL. You need to have full control of where your throttle position is, and by taking away from your gas pedals throw, you are in essense ruining your chances of controlluig your engine that much better.

Performance gain: NONE
Money wasted: Whatever you spent
Chance at messing the install and screwing up a perfectly working part...: Priceless

His explanation is right on. I bought the weapon R throttle rotor and had MAJOR fitment issues as well. I took the entire throttle assembly apart trying to figure out how to get the sonova***** on there. I had come to the conclusion that the throtte rotor wasn't ACTUALLY made for our car. I emailed Weapon R and they gave me the runaround. So I say screw em. Basstib currently has my Throttle rotor on his car but is not using it because the throttle cable has to be adjusted longer in order to fit (not something I wanna mess with right now)

The reason I know is I tried to help a friend install one of these, and I was against it the whole time (for theoretical (at the time) reasons). Once we finally got i on there, adjusted the throttle cable, it snowed. hard. Before, he never had trouble getting his civic around in the snow, but he said it actually made the throttle more finicky, because where it used to be say 10% throttle, is now 15% and he had to learn how to be even softer on the gas, but said it was really hard to get used to it. The rotor he had said it was 40% bigger or something like that, so you can imagine the difference in throttle position. As soon as the snow melted, we took it off and put the factory one back on, but it took us a while to get the frickin throttle cable to work right after that. Not owrth the trouble for a part that doesn't actually change anything except maybe 2 inches of total foot movement. We all know how precise we are with our feet... (sarcasm) why make our selves learn to be even more precise? Plus, you cant open your throttle body more than WOT, and our factory rotor just fine getting to WOT. same airflow, no matter which rotor got you there.

The trottle rotor become popular in the civics. They were running out of things too sell to Honda drivers so they cooked this up. I was watching one of those import shows and they have a project civic and put one on. They were soo exited..like it was a head swap or something!

Mike-
Heon intak re's the deal on the throttle rotor. The premis is that the turning radius with the new rotor is shortened due to it's decreased size. It was claimed to be CAD designed and thoroughly tested. The problem here is that not only does it snap the throttle open faster, but when you dump the throttle after hard acceleration, it closes equally quick. So quick in fact that the throttle actually closes before the cable retracts fully. This causes the cable to have too much slack and if you have the 6 speed where you are shifting gears and the throttle is opening and closing in quick succession, the cable pops off the rotor. I talked extensively with Chris at Weapon-R after I installed mine and he said he would pull their tuner Tibby in and do some testing. Apparently when they did the install, their car was new and they were still doing the break-in, not floggin the throttle.

Weapon-R does make some great products, their Dragon intake is cool, even though it is a tight fit.
I just think they need to spend some more time at the drawing board with this one.

Hope this helps!
