The engine fires a piston on every rotation. 4 stroke, 4 piston..............

Why the need for a heavy flywheel? Light means quick acceleration and quick deceleration. Comes down to how the driver manages the car............

I just got word pulleys should ship out mid next week. Let the crying begin!

I have mine installed. Love it!

Thank you Chino Charles!

Astroman, can you feel the difference in rev speed? Engine idle? What is your take on it?

It revs up quicker, which I notice the most when I give it more than half throttle to full throttle at speeds above 30mph or so. At a standstill in "P"

when I rev it up it sounds smoother. As far as idle goes, it seems like the car is quieter now. From about 20ft away I can barely here it running, and thats with the TRD exhaust. All in all the car feels lighter when I give it some gas (or a lot, lol), seems smoother and revs up quicker. I haven't got the numbers yet on MPG (the last time I checked before the install I got 28.9mpg, but I was pushing the car pretty hard in town and on the freeway, almost all of my driving was in town for that tank). I do know I filled up a couple days ago and even with all in town driving my gas gauge hasn't dropped a bar. I should have some good numbers next week.

I love my NST pulley. My idle seems smoother now than it did before and I have better response in every gear at every RPM. I hope they release other pulleys for us soon

Any GB gonna happen for a complete pulley set once they are ready? If so, ill just hold off until then.

ChinoCharles · 03-30-2007, 02:25 PM

I'd hold off.

I don't doubt it! It was just EXTREMELY funny. In the year or so I've been here looking at that sombrero, nobody has asked that.

to you my friend! WELCOME TO YARISWORLD!

Far, far away in a land unspoken.

Hmm...anyone know what the effect this pulley change will have on an auto trans? Same as manual? Any point in changing it at all?? Wanted to change my flywheel...to a lighter one but turns out i don't GOT one! heh heh...

I have the auto, and I can say, the NST pulley made a difference. I am getting better gas mileage, more mid-range torque, a quiet engine, and better acceleration. Not so much "off the line" but very noticeable if you already have some forward momentum and give the accelerator a push. It also weighs about 2lbs less than the stock pulley. I love mine and did notice the difference.

Cool....thanks dude...in that case i will consider getting it! Heh heh...
