NST (NonStopTuning) Pulleys. Info, Specs, User Data... - Page 2 - Toyota Yaris Forums

*Astroman* · 04-05-2007, 01:24 PM

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.

Has anyone else had this?

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.

If I remember correctly, the manual says not to warm up the car, just take it easy till the light dissapears

Yeah, I used the blue loctite... just in case it ever does have to come off.

PetersRedYaris · 04-05-2007, 05:30 PM

That red is too strong in my opinion. I always use the blue medium strength and still think it's tough to get bolts undone somtimes.

Sure, for car parts. Air tools won't work on Mt. Bike parts.

No. The old Yaris has a 2 belt pulley, from what I understand. You may be able to use a Scion pulley. Ask the Scion guys over on Scionlife.com.

Hey NST or Chino... are there any plans on making an A/C pulley as well? Heck, I'm not even sure if its replaceable..!

Very good question Doc!

Chino gave you a very good answer there, but I will take it one step further for you. The A/C pulley on most Toyotas is a "clutch-type" pulley. This clutch engages from time to time in order to start your compressor. Building a lightweight version of this type is very difficult and very expensive. And to be honest with you, the gains would not be worth the cost. Those building track cars would rather eliminate the A/C unit.

Other Updates:

We are currently working on a few things for you guys. Some of these are new alternator and water pump pulleys. Keep an eye on our site for a summer release.

Last but not least... Contrary to popular belief, supply of aftermarket products relies much more on the DEMAND side rather than the supply side! And demand does not mean you guys posting on forums and saying "build stuff for us!" Demand means you guys supporting the aftermarket companies that are willing to cater to your needs, build and test quality products, and offering you a great value. The more you support these companies by actually USING their current products, the more they will be willing to build you other products in the future.

Having said all of this, I want to thank all of you who have supported us thus far. I promise you that if you keep supporting us, I will keep working very hard to design, test, and bring new products to the market for you guys.
