NEW GROUP BUY: Yaris NST Crank Pulley (NonStopTuning)

[NonStopTuning]

Ok guys and girls, I'm back to say hello :)

First of all many thanks to all of you that have signed up already, especially RiceBoy and ChinoCharles for their kind words and the posting of the dynos that I shared with them. You really don't know this yet, but you are helping to bring a product to your community and getting involved with a company that really really cares about the customer and the product.

Now strap in because you are about to get a novel!

1. Regarding Light Weight pulleys vs Underdrive pulleys.

There is a ton of info about these concepts on our website and I will share just a tad with you here, you can look on our site or ask me on AIM and I can explain more. Also a lot of this info has been posted elsewhere on the internet by many of our customers and friends...

There are two benefits to NST pulleys. One is weight reduction, the other underdrive. Weight reduction leads to extra throttle response and a bit of HP and TQ being freed up and sent to the wheels. Underdriving from the crank pulley means sending less power to run the accessories, thus sending even more HP and TQ to the wheels.

The pulley we are offering you guys is of the first variety, it is an OEM diameter, lightweight crank pulley. We call this CR-Lite.

I will share some pics with you in the near future, but know this for now... The design of your crank case and your OEM crank pulley make it very difficult to design an underdrive crank pulley small enough to actually do any underdriving! If we could do more for you, we probably would, believe me.

Also, an underdrive crank pulley would slow your A/C and alternator by a tad, and many of you complain about your A/Cs being weak as they are. Most of you do not seem to want them any weaker.

90% of the time I am actually in favor of an underdrive crank pulley... but after doing some research I have come to the conclusion that for your Yaris a CR-Lite may actually be the best fit and best option.


2. On the topic of CR-Lite making your car more jumpy/harder to drive...

This idea comes from the school of thought derived from a light weight flywheel. Typically when you install a light flywheel you are doing weight reduction in the neighborhood of 10lbs. Not always, but in many cases.

That is a drastic change and people often talk about their cars being more jumpy. Our crank pulleys do not lead to such effects. Ask anyone who has ever owned a car with any NST pulley and they will tell you that they would never switch back to OEM. This is not BS!!!


3. On the topic of harmonic issues and engines blowing up....

I could write 3 pages on this alone, so I will try to make it short and sweet.

There are a few people on the internet who like to act as though people who invented pulleys murdered their mother and seem to be on a witch hunt!!! They will go to great lengths to prove to you in theories that solid pulleys will blow your motors. Sadly, their evidence is 90% theoretical and internet hearsay. He said, she said. Some ricer threw a bunch of mods on his car and blew his motor, so it must have been caused by the pulley!!!

In theory it is true that any extra vibrations are bad for small, high output, high reving engines. This is absolutely true and I would not recommend a solid pulley for a 1.8 liter, 450 HP, 10,000 RPM motor. Does your Yaris fall in this category?

We are capable of building dampened crank pulleys, but such a pulley would MSRP for $300 rather than $110, and you guys do not want to pay such high prices for something that is not necessary.

I have personally been in the pulley industry in one way or another for almost a decade. I have owned several race cars and I use NST pulleys on every car I own. As you look through our website you will see that we have a few cars that compete in professional drift events such as Formula D events. We have never ever had to rebuild a motor because of our solid pulleys. And these cars do nothing but run on race tracks. They are in fact modified for high horsepower, higher redlines, and spending their days and nights at higher RPMs. We have never had issues with these cars.

Would we really put weak sause products on our own race cars and take them to national events only to look like morons in front of all those people watching?

Like I said, this is a very hotly contested topic on the internet and we could go on and on and on and on arguing theories and formulas. I have made an effort to explain this to you in lamens terms, simple common sense, and my own personal experience rather than what is posted on some random website.

You can choose the route you desire, but please do not follow blindly. Try to learn from real facts and real world testing. Ofcourse naturally, I am only here to try and sell you a product. I obviously don't know what I'm talking about

Finally, on the topic of aftermarket pulleys blowing up motors...

Please take a look at this interesting thread on www.ScionLife.com...
