Yep count me in too! By the way since all the pulleys are Lite pulleys, that means everything is the same as stock size pulleys but much lighter?

Sorry if this is a basic knowledge. Is that the Water pump pulley? If it is then it must weighs a lot, and upgrading it to NST means a significant reduction?

curik,
That is the a/c compressor pulley. The water and alternator pulleys are located just above it. It certainly does weigh a lot. Other than the crank pulley that is the largest pulley on the 1NZ. If you are planning on tracking the car, the solution that would bring the highest power gain would be to outfit your engine with NST pulleys, find the proper size belt and bypass the a/c compressor altogether. For track purposes it is only leeching your power. Swapping the belt out would only take a matter of minutes, and the benefits of not running your a/c compressor when racing are very tangible. You will feel a difference. |

Thanks for the excellent explanations Chino! Since the A/C pulley looks massive, why doesn't NST make a replacement for it as well? I mean, it looks more parasitic than the WP or ALT pulleys together.

correct me if I'm wrong, but the A/C pulley is on a clutch that is directed by the ECU when to turn "on" and "off"? I think this makes it problematic to re-engineer for aftermarket use.

You're not wrong, but NST has already said they are not making a A/C pulley. The pulley set will be for the alternator & water pump. Their post is on here somewhere about it.

Track only race cars do not have a/c systems at all. And like others have said, if you want to build yourself a hardcore street car you will eventually end up taking your a/c out to save a few pounds of dead weight.
I have the NST crank pulley now and I'm anxiously waiting to get the alternator and water pump pulleys later this summer. I don't think I could ever go without my a/c during the summer heat!

We are going off topic slightly here, I was wondering if there are issues for making a lightweight A/C pulley that make it not possible to do. It looks like the 2nd heaviest pulley in the whole system and why doesn't NST consider making it at all?

I want my A/C to blow a whole 2mph faster on max AC speeds!!!
I demand Lighweight A/C pully now! Actually I dont see why not, it would just mean more $$ in the bank for NST!! I would buy, but the point is not to use A/C while in High Performance use.

I agree with you Sabretooth, but sometimes we want to maximize performance with the least sacrifice in comfort. So if NST makes the A/C pulley, putting a whole pulley kit on a completely stock yaris will be a significant addition in performance and fuel economy. However there will always be trade off like increase in vibration, but this is minor and I am sure it is worth the trade off.
