Well I just installed the 20% underdrive Crank pulley, light weight Water Pump pulley, and 20% over drive Alternator pulley.

I'm really enjoying the affects of the pulleys. The low end power has been restored from the "airy" feel from installing my exhaust. Throttle response is enhanced and idle seems smoother. Great mod!





Thanks NST!

 

I already have a lightweight crank pulley, I haven't yet installed my 9.5psi S/C pulley.
I was going to leave the other's alone, but this thread may have just provided me enough motivation to finish off the pulley setup and swap out the Alt and W/P pulleys. Way to sell!!!

 

Thank you for the recent feedback and the comments guys. I am happy to hear that you guys are happy with our products and service. Much appreciated, as always!

 

Any other reviews, thoughts, or comments from recent customers is always welcome and appreciated.

 

If I'm on a budget, what pulley do you recommend to get? I figured I'd have to get a belt, but wouldn't be able to get like the water pulleys and all the extra stuff. Just the most basic pulley or cheapest way to go if I can't spend for all the parts. I have a Poweraid Throttle Body spacer and TRD Intake installed along with the TRD Exhaust. And how much would all the stuff be with shipping to 91352? My purpose is simply for everyday driving as I do not plan on racing at a track especially with an automatic. Thanks in advance.

 

If you are on a budget, then we would recommend going with the Underdrive Crank Pulley and the correct belt to get you started. This is the main pulley and the majority of the benefits are had when using this pulley.

You can then add our other pulleys at a later date in the future.

Shipping is always calculated by our online shopping cart at the time of each order and payments can be made via PayPal, Debit, or Credit Cards.

Thanks again!

 

is there an issue with dampeners in regards to installing this? I've been reading around and this seems like the same as ZPI pulley and that one has been said mess up your engine over time.

 

There are no issues when using the NST pulley. The NST pulley was the first one offered for the tC in 2005 and there are numerous replies here in this thread from Scion Life forum members who have put 70K, 80K, 90K miles on their cars with NST pulleys.

Please feel free to read back through this thread and you will find several in depth discussions regarding vibrations, harmonics, and NST pulleys ... along with feedback from real world users.

Not all pulleys are created the same, and no other pulley is an NST pulley!

 

Hey Mike

I called a little while ago about a whining that occurred during acceleration. I went to Advance Auto and picked up a couple belt sizes that were smaller than the k060739 that I purchased off of the NST website and ended up using a 06735 belt which eliminated the whine.

I noticed that the K060739 belt that I purchased from NST had a different rib pattern than the OEM belt and the 06735 belt I am now running. I was thinking that the pattern may've contributed to possible slippage. I should also note that the NST recommended belt size I based my initial decision on applied to 07-09 Scion tC's where I have a 2010. Not sure if anything really did change, but it's something I thought was worth looking into if it would allow others with 2010 tC's to avoid the incorrect belt size.

Still love the pulleys I just have a couple extra belts lying around

 

i read through this post and didnt find exactly what i was looking for. on the 20% underdrive crank pulley, how does it effect the air conditioning system?? is there any sort of noticeable decrease in how well it works due to the a/c compressor rotating slower??

 

watching..

I am considering using the NST pulley system, but want to know how it effects the A/C as well...

Does it make the air come out warmer when on max a/c?

 

Just ordered the UD Crank for my xB. Whats the torque required for retightening the crank bolt?

 

This topic has been discussed many times. A great number of our customers worry about a/c output before purchasing our Underdrive Crank Pulley. These same customers always reply with positive reviews after installing our pulley.

As I have stated before, our pulley does not slow the a/c system, or any other accessory, in such a way where any negative side effects would occur. You do not need to worry about your a/c or any other accessory when using the NST Underdrive Crank Pulley or any other pulley.

Good luck and have fun with all your projects!

Its on my list...

 

Speaking to the performance guys, Dan Gardner being one, the NST pulleys are great units, and the only real concern would be if you had a big audio system.

 

Really no need to worry if your OEM pulleys and OEM alternator are currently capable of handling your electrical needs. The combination of the NST Underdrive Crank Pulley + Overdrive Alternator Pulley drive your alternator at the same speeds as the OEM pulleys... no slower, no faster.

If you need a little more, pick up the NST CR-Lite Crank Pulley along with the NST Overdrive Alternator Pulley. This combination will provide you with better alternator output at idle and low RPM.

In either case, the NST Water Pump Pulley can also be added for more weight reduction and better overall performance.
