I have been to your site but could not find my country on your shipping list.
What would the cost of shipping work out to?

Hi shadow,

Do you use PayPal in South Africa? If so, you will be able to use our online shopping cart.

For anyone else reading this... customers in the USA and many other countries, our shopping cart can also process credit cards, debit cards, and PayPal payments.

Thanks again!

shadow 09-18-2009 02:22 AM

Yes I do have a paypal account. Okay I've been to your site and I now see my country listed in the drop down box. I have one final question. Customs are a bit steep in my country, would you be able to make a plan with regards to this.

Thanks

Glad you found it! Unfortunately we can not lower the value of international packages, we always list the full value. Undervaluing an international package is both illegal in the US and illegal internationally, therefore we will not do it.

Thanks again, good luck and have fun with your project!

yeah im really looking forward to seeing how these do for everyone so that when i can actually spend some money ill know whether or not to get them. happy modding!

black09Z 09-21-2009 11:59 AM

so since these two pulleys together make the same power as the stillen by its self, would it be safe to assume that if i get the stillen crank pulley and the NST alternator pulley then it'll make even more power?

That is a good question!

And in theory... there may be a 1/2 to 1 HP difference there. I would imagine the difference would not be noticeable by anyone... nor would the increase in price be justified by most.

But we can see some wanting to go that route, which is why we offer our Overdrive Alternator Pulley for sale separately for those who may want to.

Good luck and have fun with all your projects!

What does the 7AFE pulley kit come with? Is it just the underdrive crank pulley?
Does the crank pulley come with a damper? and how safe is this pulley to use on a an engine that makes over 200HP?

shadow 09-22-2009 04:54 AM

One more thing... could you e-mail me a pic of the actual pulley to supersnake500@yahoo.com that you are selling. Thanks and sorry for being a pain and asking so many questions?

The crank pulley is the only pulley offered for the 7AFE, it does not have a rubber damper in it, and we have never heard of any NST customers report any engine problems when using our pulleys.

Pictures are listed on our website, and we have less than a handful of these pulleys in stock. Once they are gone, they will no longer be available due to a very very low amount of demand from the community for this pulley.

Please hurry if you are seriously interested.

Thanks for your prompt response. Will be ordering one soon.
Here in South Africa there alot of 7AGE's moddified motors running in our streets and the guys are crazy for more horsepower. That is one item you should be stocking up on. Once they find out that the NST pulley is working, you are gonna have a lot of orders to contend with.

DIGItonium 09-23-2009 10:41 AM

I'd be interested, but I'm still concerned about belt issues in the long run. So I'm sorta playing the waiting game... any gray ones left?

Yes, red and gray kits are in stock.
Belts are usually only about $25 to $30, you only need one belt, and each one is usually good for about 40K to 50K miles.

If you install both pulleys, Gates Belt K070786 fits perfectly.

Much appreciated. How's the fun factor in the higher gears (i.e., downshift to 2nd or 3rd and noticed slight lag... even worse with A/C on)? This is probably the most I'll mess with besides ECU tweak to further improve throttle response.

Most of our customers have reported much better throttle response through the entire RPM range, leading to smoother upshifting and more precise downshifting, due to the fact that rev-matching becomes easier with a more responsive engine.

Our 370 kit has been one of our most popular new kits and customers seem to love the benefits!

While our 370Z kits have been very popular for us and have been selling quickly, we do have quite a few kits in stock at the moment.

We'll be here when you're ready :tup::tup:

I just ordered mine from DD last night, with the new belt.
Should have it on the car in 2 weeks.
12.7's here we come.
Will post dyno results.

:tup::tup:

While what your saying is probably true that people do report it, personally seriously doubt a true perceivable effect. Happen to also be one of those that when the oil is changed, the car seems to run better yet I really know different.

Any performance car can have as much as a 15 hp greater gain just from morning to afternoon by having a front of cool dry air pass through yet no one seems to notice it. Butt dyno's seem to break down easily, results aren't very reliable and the correction factors way off. Hell, the air conditioner is usually a 20 hp parasitic drain, yet I'd bet most can't tell if the air is on or off when they drive.

In comparison to other cars I've owned, one of the things I don't like about the 370Z is a delay in throttle response and a disconnect feel regarding revving both up and down. Simply a lag and delay I'm not used to. Hoping tuning software will correct this somewhat or it may even be a hidden function of the Rev Matching that I never turn off.

What I did notice from an under drive pulley is the car is less prone to spinning the tires upon hard shifting as the lighter pulley reduces the flywheel effect. The clutch may also be breaking in and that might contribute to the lessened wheel spin also but it would be very coincidental if it did.

Anyone whom is saying they notice a 3-4 hp gain is smoking some good dope or seeing the image of Christ in clouds. Maybe both. A wise decision to add the pulley(s) however, as 3-4 hp gains are how the big NASCAR and NHRA boys do it and it all adds up.

DIGItonium 10-01-2009 11:12 PM

A/C definitely worsens this lag and delay that's so annoying when punching it in the higher gears. How's it going for you with this mod?

Going to have to say.......Great!!

Honestly, except for not spinning the tires as hard when you shift hard; can't tell the difference which probably is a good thing. By not spinning the tires as hard tells me the energy which would go into spinning the pulley instead is going to the tires. Which is also a good thing. Was surprised as to just how heavy the stock pulley and basically a mini-flywheel.

Been putting off putting the car on the dyno waiting on AccessPort software to get objective results, but in my mind until anything is proven otherwise, something I'd certainly do again. My next priority is getting the 4.08 gears (ordered two weeks ago) and getting them squared away but right now I'm a happy camper.

Most any good shop including the dealer can install it if they have the proper pulley puller. Expect to be charged about 1.5 hours labor. With the right tools it's not a bad job. With the wrong tools....close to impossible unless you get lucky.

tcarretti 10-13-2009 06:37 PM

Ok, got my oil changed AND had my NST crank pulley and alternator pulley installed at the same time.

First of all, let me say that the pieces look great. They are SO much lighter than the stock units and the quality looks fantastic.

I had a mobile mechanic come by to do it. He used to work at an Infiniti dealership so he didn't have too much of a problem installing. He did say that pulling the stock alternator pulley off was a bitch from underneath, but he got the whole thing done in about an hour.

Driving impressions:

The care definitely revs more freely and seems to accelerate quite well. I don't know if it's just me, but it seems that there is less vibration than before also. I was expecting the opposite, but was happily surprised that the car felt smoother overall. This was the first mod done to the car and I'm happy that I did it. Once I drive it more, I'll post any other impressions that come up.

All in all I give NST a big thumbs up for great service and information as well as supplying a quality product.

Tony

tcarretti 10-15-2009 08:41 PM

OK, have put about 100 miles on the car since yesterday's install. No problems whatsover. My amp gauge is reading just like it was before the pulley install, and YES I did install the alternator overdrive pulley.

More observations:

Besides being substancially more rev happy, I've noticed that the shifting doesn't feel anywhere near as "clunky" as it did before the install. I don't know if the extra inertial mass of the stock harmonic balancer had anything to do with it, but it is NOTICEABLY better now. I've also been resetting my MPG computer and have noticed the average seems to be 2-3 mpg higher than what I was registering before the install. I will run a couple of tankfulls through and monitor the numbers to make sure this is for real.

Thanks again to NST, I'm happy with the mod and am looking forward to doing something more substancial in the near future. Guess I'll wait until SEMA to see what's available.
