Any other reviews from recent customers would be much appreciated!

MIKE @ NST

I'll offer up my .02 real fast since I had these put on last Saturday.

Woke up around 8:00 am and set out for the short 3 hour trip to Houston to pick up the parts and have them installed. I wanted the install done by them since these were their parts and all. On the way out though, I pulled over and took a quick video of how well the car reved up in neutral after it had time to get up to operating temperatures. Did a few quick pulls before continuing on.

Once I got there, picked up the pulleys and belt and ended up having a different shop do the install as NST had a hiccup on their end. They said the shop did good work and had done this install before so I went with it. Install took about 2 hours and then I was on my way back home. Once I got back into town later that evening I took another quick video of how well the car revved up with the new pulleys.

I will work on getting the videos uploaded soon, but it is going to be contigent on when my friend has some free time as I want to edit the videos together where everyone can visually watch them rev together and see the differences.

The things I noted are:

-Pulleys did free up some power.
-No change in sound from the engine or anything. Everything sounds just fine.
-The stock pulleys are HEAVY!!!! My goodness they were heavy in comparison...
-Revmatching is a bit easier.
-IMPROVED GAS MILEAGE!!!!!!

I want to call special attention to this last one because I really feel that it is often overlooked when people discuss modificatioins to any vehicle and it really frustrates me because I am a stickler for maximizing the efficiency of a system, in this case the engine.

When I set out Saturday morning and got on the open road I reset the in car instrument that records average MPH and average MPG and drove very conservatively, trying to maximize my MPG. I originally planned to fill back up once I got to Houston and get a hard figure, but they unplugged my battery and it erased my trip numbers (o the joys of the digital age). However, the in car instrument showed a solid 27 mpg for most of the trip. Just for reference, the stated highway mileage is 26 mpg.

Post pulley install, I filled back up, reset the in car instrument and hit the open highway driving the same way. On the return trip I recorded a solid 29 mpg and verified it after getting home and filling the tank back up.

That is a solid 2 mpg increase or a 7.4% increase in gas mileage which is IMHO, pretty substantial. I will be keeping a close eye on the coming weeks to see if I get similar results under normal driving conditions.





As an aside, there was a section of driving where the speed limit was 55 mph for probably 5 minutes of time with pretty even terrain. Before the pulleys, I was seeing around 28.5mpg and after the pulleys I was seeing around 31 mpg, or about 9% increase in mpg.

Thank you for the very thorough review. Everything you have stated here is on par with what we have seen with our pulleys over the years.

Glad to see other real world pulley owners post their own independent results as well!

Thanks again for coming down and very glad to hear you are happy with your purchase.

Any black Friday sales?

I am sure this has been covered somewhere in this thread, but there are a lot of pages to sift through for it so I hope some kind member can just answer them for me. Spikuh's great review answered a lot of the questions I was about to ask, but here are a few for clarification.

Do the pulleys come with install directions and is that 2 hour install time pretty standard from most people's experiences of having someone do it for you?

What is the general consensus for approximate gains and can you actually feel it?

Would I need to be concerned about replacing them after a certain number of miles or will they affect the need to replace any other engine part sooner than usual (engine longevity and maintenance)?

Spikuh's MPG comments are very appealing too, has nayone else noticed such improvement sin this area as well?

Sorry for the repeat questions if they have already been covered.

Thanks a lot!

Also, is this a pretty standard install for a mechanic or if it's more specialized, cna anyone recommend a good place for it in southern California?

Thanks!

Is this the correct belt? Amazon says this doe snot fit the 370z.

Okay, I'm impatient and have read through most of this thread so you can nix my questions about install time and gains/feel.

I am still wondering though if it comes with install directions.

Also, will my car being a 7at make any difference in the effects of the pulleys on drive feel and throttle response that most people are reporting as a big benefit of the pulleys?

I have sen varying reports of MPG gain ranging from .2 to 2mpg. Can people chime in with what kind of mpg improvements they have experienced?

Sorry for the multiple posts and thanks a lot!

When I get mine, Amplified will do my install.

Amplified Motorsports in Monetery Park? I'm right by MP on weekends.

Yea them. They've done all my installs that I can't do myself.

Cool, I just looked them up after Triples mentioned them and discovered they are close to me. Do they have good rates for labor?

Yup probably the cheapest rate you will find. That's why I always come back to them.

Thank you for the interest and the inquiries, much appreciated.

Yes, the gains are present and visible on auto and manual cars.

Gains in MPG are present and vary based on your driving style.
Keep your driving habits the same as before and you will see anywhere from 1-2 MPG increase.

Most shops will charge 1 to 2 hours in labor and you will need to use the shorter belt that we list on our website.
This belt is intended for use with our pulley kit.

Feel free to contact us by phone Mon through Fri and we would be happy to answer any questions in full detail.

Thanks again!


MIKE @ NST

Thanks for the reply. I will probably order early next year since I just had CBE, HFCs installed and am getting an Uprev tune. Spent a bit of money on all that and also want some time to drive with those mods to better appreciate and gauge the differences when I get your pulley kit.

Looks like your questions got answered brucelidat, but just echoing Mike, the shift in mpg will be enitirely dependent upon your driving style and the type of driving you do. If it is a lot of city driving with stop and go, I would not expect much help if any from these pulleys. If it is exclusively highway, they can be good for a nice 2 mpg. Mixtures in between will give you a result within that range. :tiphat:

ill speak as to quality and ease of installation, everything fit well with no issues and the quality was definitely there, as to the performance i couldnt tell due to the fact i installed them at the same time as my turbo install, but im sure i got something out of it :p

Thank you for the kind words, much appreciated. And you definitely did gain some performance...
even if it was overshadowed by your new turbo kit!

Best of luck with all your future projects!


MIKE @ NST

Mike@NST, you will receive a PM tonight. Uploading pics.

Checked, and replied. Thanks again!


MIKE @ NST

Couple questions.

Earlier in this epic thread, some issues with the stock belt were brought up. I see now on your web site that you offer a belt option, so does that mean I need that belt, or will the stock one work ?

Also the shopping cart does not provide an option to select what color I want ? I don't see how you select whether you want under or over alternator option with the kit as well.

If going to these pullies, I would say the shorter belt is a must have. I saw in another thread that their stock belt had 1/2" of play and if your's is the same I would imagine that can't be good at all.
--edit--
Reference to said post: http://www.the370z.com/engine-drivet...ml#post1490662

Thank you! We recommend using the belt that we list on our website. This belt has proven to work very well on the 370Z.

The shopping cart allows you to enter a note with your color preference at the end of the ordering process. This is where you enter your color choice.

The two pulleys that we offer for this application are:
Underdrive Crank Pulley NST13710
Overdrive Alternator Pulley NST13722
the TWO PIECE KIT is NST13710K

Thanks again!


MIKE @ NST

I installed the belt listed on the NST website, Gates K070786 today. It takes care of the issue with the relaxed tensioner and slack from the use of the stock belt. Buy the belt with the kit and you will have all you need to install your kit with peace of mind. Check out my Journal for picks. I'll post video when my CBE's get in.

Thank you, Thank you :tup::tup:


MIKE @ NST

do you need the K070786 Belt if you're getting the 2 pulleys?

Yes you do!


MIKE @ NST

PM'ed

How long should I expect the install time with the two pulleys? I wanna make sure the mechanic quotes me the adequate time to get them installed.

On a new-ish car a competent mechanic shouldn't spend more than an hour or two on this really. Drop the front swaybar out of the way, maybe pull the radiator fan assembly out of the way, lock up the flywheel and break the tough-ish crankshaft bolt loose, then it's just a simple matter of replacing the pulleys and buttoning everything back up. It took me a longer, but I was doing it at home and without second set of hands present to help with breaking the crankshaft bolt loose.

Got my pulley kit in the mail today! Should have it installed by Sarurday afternoon.

What do you guys have to say about all these rumors of lightweight pulleys seizing up on the crank?

Please review the first few pages of this thread for very detailed discussion and answers to your question.

In addition, feel free to review the 30+ pages to this point, in this thread, and you will find no damage to any of the board members engines when NST pulleys have been used.

Thanks again!


MIKE @ NST

Awesome! Be sure to post pics and/or a review in this thread :tup::tup:


MIKE @ NST

I have some of y'all pulleys somebody pulled that on me on another thread and I was being lazy and didn't want to read 30 pages of mostly junk. Great product if ya ask me but most of the gtm people think differently. I was just wondering. Thanks tho.

No problem, you're welcome.

And if you take a look through the 30+ pages of this thread you will find feedback and review from people just like yourself who have REAL firsthand experience with our product.... they do not speak based on theory or formulas... they have posted their real experience with a real product. 30+ pages of nothing but positive reviews and positive experiences when NST pulleys have been used.

In addition, there are dozens of other forums where our customers have posted similar positive reviews when NST pulleys have been used on Nissans, Hondas, Toyotas, Scions, Hyundais, Lotus, etc. etc.

Thanks again, best of luck with all your projects!
