I'll refrain from ranting and raving about these again... just know that if you don't have one yet, you're missing out.

Dude! Give me two weeks. I already blew my paycheck on fogs and a bunch of other stuff. Oh...my car note? Yeah, I guess it would be pointless to buy stuff with for the car and not the car itself. Hopefully I'll be ranting and raving soon.

I had mine installed recently and I love it. Big increase in throttle response. Best $100 mod I can think of

Damn Chino, you're bumping this thread like it were Paris herself.

I am interested in hearing more personal experience from others about this. I'm very tempted to get one.

This is definately well worth it. I've got it on my car and the biggest difference I noticed was a much better throttle response also. Highly recommend this mod to anyone who hasn't done pulleys yet.

Having driven the car for a few days now, here's a little update.

The good: I'm still lovin' the NST pulley. Couldn't be happier. Mid-range really is much more punchy. Feels like more than 5 hp but who knows. All I know is that it revs much faster and seems to pull harder. I can't wait for the other pulleys!!

Other than the increased performance, the car idles a little rough, especially when warming up. Even after it's warm I can definitely feel the engine vibrating more than before. This is only at idle.

I have the five speed and I've noticed that takeoff requires a little more clutch than it used to. However, once rolling, accelleration is smoother than before. The last thing is that the car doesn't want to creep as easily at low speeds which sucks in traffic. Buuutt.... accellerating away from the toll booth is a blast!!! Anyway, my 2 cents.

The extra clutch is required as a decrease in rotating mass equals a decrease in torque. Should be better engine braking though. Wonder what it feels like on an automatic?

Question: Some new vehicles require a new crank pulley bolt if it has been removed, sort of like a one time use head bolt, because they stretch and are considered a one time use item. Is this true with the Yaris? If the crank bolt worked it's way loose because it was reused when it wasn't supposed to be that would be bad.

I'm going to talk to a service guy I know down at our Toyota dealer and see what his take is on this mod.

Engine braking is a little better but is negligible. I have no idea about the auto. Anyone care to comment on the auto?

As far as using a new bolt on the crank pulley, I didn't need a new one. My mechanic installed it for me (he had the air tools and hoist) and I haven't had a single issue. As for the engine braking in the auto, I haven't really noticed a big difference. I have been trying to use DFCO as much as I can in town, but this was after I got the pulley installed. Can't really say it changed much at all. Also the local drag strip opened up and has a schedule now, I am going to get my Yaris (after CAI) and LeBaron turbo out there and have some numbers soon.
