This is a very good point.

WOW.

All of this because I simply asked *MAD DOG* to get an opinion on the subject from his tuner.

Unbelievable.

Don't blame me for this. You went......

Ah, the great "what if" scenario. I've had over 50k miles of trouble free operation with the complete pulley set installed. There's my real world data.

WeeYari · 02-08-2010, 02:24 PM

Off-topic...not really.

Your original post.

Looking forward to it and will post results.

Part of posting results could have been insight from your mechanic. Who knows, he may very well have given this thing a

endorsement.

Anyhow, this has made for some entertaining reading, and nothing but the same old, same old has come out of it.

Love that word.

MiniTRD · 02-09-2010, 02:38 AM

Just saw this thread -

just a question for the OP

do you only get Toyota branded parts, fluids, etc?

because I'm certain that not all oil manufacturers have tested a yaris at different mileage. so by using your logic, their statements about engine protection might be false. . .

you can apply the same logic to any sort of part or fluid that isn't a Toyota product. . .

so what's the point about continuing to badger NST on a public forum? a lot of your questions were better suited to a PM instead of creating a soapbox here. I mean most people call the company directly instead of getting them to respond to a forum on a specific car

just my thoughts and I'll shut up now

Hi i am an engineer. camelll is right to an extent... Toyota builds there cars to last longer than there competitors. Thats how the make bank along with mpg. Any modification made to our car that is not an upgrade in durability AND quality, will shorten the life span of our car. Learned in my automotive class. The question is by how much. I have the pulley and love it. I know some Yaris owners that have the pulley and after 100k miles have not had a problem as a result of it. That makes me thing the product is reliable for the purpose it serves. NST made a reliable product and it should end right there IMO...

bzinn 1 · 02-09-2010, 03:20 PM

30000 miles with them on my Scion and never a problem car has IHPE....best mod was the pulleys it really cleaned up the of the line acceleration........There are guys running them on their xBs and xAs on scionlife for over 100000 miles and no problems,same motor we got short of throttle body.......the thread on scionlife is well over 70 pages of discussion and hundreds of owners with the very same thing to report.........no problems.

One thing no one has considered is how long the rubber dampner on a stock pully that is 2mm thick will last .......pop one off a motor with 50000 miles on it and it is starting to wear out.....

Once the dampner wears it does nothing for the crank or bearings to reduce harmonics.

Toyota over built every motor since day one to do one thing and do it well.......last for a longer time than any of the compitition......

NST has built a great product and it works and that is a fact.........will the motor last a shorter time........possible yes.......but how long was it going to last to begin with depends on how it is used,how it is maintained,and many more factors.

Do you think our engines were built using the specs of a balanced engine?

You already know that there is no concrete definition of that. There is quite a bit more balancing that can be done with this motor. I know, I've done some of it.

So, you continue to argue from points you know aren't solid. It's a vapor argument, and by this point everyone on this thread can see it. This is my last post on it, and of course.... you may have the last word.

Just about to click "unsubscribe" from this thread. I'd rather put a gun in my mouth and paint the walls with my brains then continue to read this drivel.

o2cavyss · 02-10-2010, 01:37 AM

While I don't agree with how Camelll has continued with all this, I have to agree that his questions to NST are not unreasonable. But even if the answers aren't what you'd want from someone building parts for cars, at this point there is more than enough proof that these are quality products. And, to be fair, anyone modifying there car should understand that they are making changes to the plan that Toyota engineers planned and tested to meet whatever needs they had (cheap and reliable) in order to make them the most profit. ANY mods will inherently have an impact on the car's reliability, and in almost all cases adding power increases stress loads on the engine/drivetrain and lessens the life of all affected components. ANYONE modding a car assumes that risk.

thebarber · 02-10-2010, 09:57 AM

i would think that 99.9% of people who use an NST pulley will sell their car WELL before they run into trouble due to an undampened pulley (regardless of whether it does any harm to the engine)....just my 2c
