WOW, not horsepower wow, but you can tell it revs sooooooooooooo much faster! I would recommend it to all of yall!

Chas2

What did you get, stock or underdrive?

Did you have a chance to dyno?

fatty

No dyno, stock size. I thought about it but from understanding it doesnt add hp but reaches rpms faster.

I am still curious about this and I asked about how fuel efficiency changes after installing UR pulley in my previous thread. If it revs so much faster, don't you get lower mpg? I'm quite confused.

neuronbob

Glad you like it. I still wish someone would do pre- and post-install dynos with this modification. Maybe I'll do it when my factory warranty runs out.

The idea is that the motor CAN wind out with less work, so it does so more quickly at the same level of fuel input. The lightweight pulleys reduce engine inertia, enabling the car to accellerate/rev with less work. If he drives the same way he did before the swap, he'll get better mileage, because the motor doesn't work as hard.

great, thanks on the feedback on the UR pulley.

fatty

Ive been flooring it every where now, dont know bout saving gas! But should I just let it learn or should I reset it?? Cuz I can really tell the difference!

Blazing GT

Is it an easy installation?

fatty

It was like 20-30 min from my mechanic, said it came right off with impact gun and the holder. I told him about how hard I heard it was, he said it came right off, mybe cuz its a newer car from what he said?

Blazing GT

so if it revs faster that means the acceleration is better right?

fongz

that is nice to hear, I am thinking of getting a ur pully too, where did you get it from? And how much did you paid for it.

I am confused as to why Honda would not do this if it is a win situation. Could it make shifting harsher and put stress on the transmission?

Chas2

I don't know, but I am guessing billet machined aircraft aluminum is a lot more expensive than steel. This is, after all, a mass produced car, at least, it was designed to be.

kirbyflorida

That part cannot be that expensive, and if they get improvement it is cheap.
After all, it has alum suspension comps, alum calipers, very costly, carbon shaft, so I do not get it.
I still think it has to do with smooth shifts and some slamming on the tranny parts.

Now I understand. Thank you so much~!

If you look at UR's homepage they are concentrating on marketing how the pulleys increase MPG: www.unorthodoxracing.com

How do Unorthodox Racing pulleys give me more power?
Weight reduction is how we are able to increase Horsepower! Each pound of weight removed from the crankshaft is worth approximately 2.7HP and the gains jump even more dramatically with forced induction, nitrous and variable valve timing. Only 15-20% of the gains from our pulleys come from underdriving. The diameter of each of our crank pulleys is reduced up to 20%. We tailor the exact amount of underdrive to each vehicle to maintain factory specified accessory output and performance. We fully maintain all accessory output minimums like air conditioning efficiency, power steering feel, and voltage (minimum allowable voltage 12v) even at idle with everything electrical on in the car. There are no adverse effects from using any of our pulley versions. Bolt them on and forget about them, then just follow your vehicles normal maintenance schedule.

We have these in stock. http://store.excelerateperformance.com

020611412 is the Ultra Sc stock size crank pulley

Perhaps I'm alone but I have avoided your website due to it's complicated listings for individual vehicles. Too many universal parts are listed and makes finding one item too time consuming-at least for me. I would have purchased a few items from you by now if not for that. Again-perhaps it is just me, I like things simple.

I've listed the part #'s on this site and also my sales threads. Also all you have to do is put in your vehicle info and then click "Hide Universals" and none of the universal parts will come up. Also, I do have a phone #; you can easily call me to place an order or you can PM me or email me or IM me via AIM or send payment via Paypal.

I know it's hard to read critical input regarding one's website and that 470hpGS400 could do all those things you suggest, but I hope you get the message that it's just input from a potential customer. In his case, it's a potential customer with a track record of spending money on his cars...check out the rebadged Hyundai Xcell he painted like a Lexus!

Seriously, I have also had some frustration using your site, and I figured out the "hide universals" trick. This isn't your fault unless you're the programmer, and I know it's harder to fix or change than many understand.
