When I said I had a 350 and a 370, I caught the same grief and I had to go out to the garage to get pics of them to keep my rep intact. I didn't necessarily feel I should have to prove myself, BUT since I'm the one who brought it up for no real reason, it was my own fault.
Now, a 350 and a 370 is much less outlandish claim than SSQ's, so it's no surprise to me that he is also catching grief.

do you have any black ones??

- Estimated install time and difficulty? Did it require timing adjustments, so just a direct swap?

- I have an audio system. I understand you have the alternator pulley, but I just wonder what sort of effect it'll have in terms of lifetime of the alternator (i.e., does it end up working harder or just running up to spec)?

Improving throttle response is a definite plus!

Thanks!

The NST Underdrive Crank Pulley is a 10% underdrive (slow down) pulley, and as you can see in the pic here, it is very close to the OEM pulley in size. This pulley is designed to slow the accessories by roughly 10%... not enough to "kill" any of the accessories, but just enough to free up a nice amount of hp and tq to send to the wheels. The excellent weight reduction also aids in providing better throttle response, quick acceleration, and better fuel economy. We did a bit of testing and decided that 10% is the sweet spot for this application. 20% or 30% underdrive may provide an extra 1/2 or 1 hp or tq at the wheels... but it may do so at the expense of some of the other accessories' functions, so we decided to stick to 10% for our pulley.

The NST Overdrive Alternator Pulley is a 10% overdrive (speed up) pulley, and as you can see in this pic, it is also very similar in size, to the OEM pulley. This pulley is designed to bring the alternator back to OEM speeds. No slower, no faster. There will be NO hp or tq loss when using this pulley. The crank pulley is the SENDER pulley and it is the pulley that decides how much power the accessories will receive. The size of each accessory pulley determines how this power is used. The alternator will not be overworked, underworked, robbed, killed, etc. when the NST pulley is used. It will work in the same efficiency range as it would with the OEM Nissan pulley.

NST Pulleys are NOT a "one size fits all" type of design. We take the needs of each application into consideration, we come up with a few prototypes/configurations, and ultimately we sell the KIT that works best based on the data we collect.

Both pulleys are compatible with the OEM belt and the OEM belt has shown to work very well during the past several months of testing. As long as you are using a new belt, or your current belt is in good condition, you should be good to go!

There are other options out there, and some of them are excellent options. We feel that NST offers the best all around kit, with the best all around options, at the best possible prices. Our customers feedback and reviews have consistently proved these to be the truth.

Thanks again everyone, good luck and have fun with all your projects!

NST,

Just a quick, stupid question as mine should be here tomorrow. I assume they have timing marks on them. I see them on the Stillen unit but not on yours. Thanks.

Other than anodized red and gray as mentioned - is there a reason they aren't offered in polished aluminum (maybe clear-coated to keep them looking great, just not on the belt area), or, black?

Also, 'nother basic question - where's the harmonic balancer with the VQ37VHR?

Thanks!

Had both the 10% crank underdrive pulley and 10% overdrive alternator pulley installed today. They thought it would take an hour but it took just about two. They ended up removing the alternator to change the pulley. Car definitely responds quicker and have noticed no difference in the power steering, noise or vibration. NST recommends using the same belt when making both modifications, however, the marks on the auto-tensioner no longer line up where they are supposed to (page EM-13 in the SM) - about 1/2 inch off. Will this be a problem and does anyone know the number of a belt that is slightly smaller? Thanks.

OK, how hard of an install is this guys? I've called around and gotten prices for installation from two places. One for $150 and one for $240... both of which I think are a little high considering that from what I've read that this is about a 1.5 hour job with the right tools.

I'm not a mechanic so I don't know that I'd be able to do it on my own, but I don't want to feel like I'm getting gouged on it either.

Any feedback or information would be great.

Thanks,

Tony

Denny,

Thanks for the info. Did you do just the underdrive pulley or both? I have heard that if you do the alternator pulley, it's best if they remove the alternator to do it.

Thanks,

Tony
