NST (NonStopTuning) 370Z VQ37HR Pulley Kit Review w/ Dyno Charts

ssqpolo · 08-30-2009, 10:25 PM

NST. i want to apologize for making your thread a big bash-fest. I hope this could some how help your sales tho!
Semtex--really appreciate you trying to stick up for me.
to those that want to bash let me clarify a couple of things. I had the R8 for a month (a little less). I have a friend (my father's friend) that owns an exotic car dealership and he is who I got it from and gave it back because I realized that I was not in the financial position at the time to get the car (economy was going down)...no harm done. he was cool with it. when I say I, i mean my brother as well. He was shopping for cars and its what we decided. Since he and I are in the process of getting the clothing line up and it is he and i that play polo and work with horses, we wanted a cool car--r8 was the choice at that time. then after i got the new Z, times got better and I was obsessed with GTR. that's why we got it. im not trying to brag. i dont like ppl that do show off. I havent been on my350 for a while, for the simple reason that i, being a student/young will get flamed for nothing. and i know this will probably get posted there, but whatever. I am going to enjoy this site, and the cars I drive. simple. Bash me all you want, its not gonna make you "cooler" or more respectable here. post a DIY like modshack, or take pics of installs like Semtex, show racebuilds/vidoes like Travis and RCZ...then you'll get the respect of others. anyway, i apologize again to NST. I hope this will all stop

Thanks! I just wanted to double check about the alternators. [Adds another toy to wish list]

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!

Thanks!

The Red and Graphite Gray are the HARDEST choices, and we build them in these colors in order to provide the best, most durable, longest lasting options to our customers.

Those who want the "tuner" look generally go with the red, and those who want the "stealth" look usually go with the gray. We have never offered bare aluminum pulleys and have no plans for any black kits at this time.

Thanks again for your interest and the reply, good luck and have fun with all your projects!

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.

Wow, you got yours installed quickly! Glad to hear that you have noticed a difference in your throttle response and acceleration. This is definitely a mod that helps in that department.

It is true that the auto tensioner will not sit in the same location as before, but this is not going to be a problem. Our local test car has been running these pulleys for about six months now, on the OEM belt, with no issues.

Thanks again for the quick post and the positive feedback. Good luck and have fun with all your future projects!

got mine in yesterday and installed myself at the shop (im a mechanic) the center on the balancer needs to ne roughly 1 to 2mm larger the other problem i ran into is the factory belt will work butt... i wouldnt use it because it is too loose the biggest problem is getting a belt that works... factory is a k070810 gates belt... you NEED a 790 but they and when i mean they i mean every belt manufacture worth a damn doesnt make a 790 in a 7 rib belt... i drove home last night with a 790 k6 on :-/ ordered a 786k7 and just got it delivered ten mins ago i will let everyone know if it works...
ps. since the new balancer is smaller than factory i tried installing it by itself and the factory belt was too loose for my liking. with the alt pulley installed it was really too short i could slide the belt off the idle pulleys w/o even touching the tensioner not to mention it was completely retracted not placing any tension on the belt
also you do need to partially remove the alt and tilt it downwards to be able to hit i

jpit · 09-01-2009, 11:59 AM

Moemeister,

Did you install the alternator pulley, also? Looking at the marks on the auto tensioner, I think I need a belt 1/2" shorter. Would you have a Gates number for that? Thanks.

Moemeister · 09-01-2009, 12:16 PM

the one i currently have on it is a six rib and it is perfect size... maybe just slightly too big the one i just got dilivered is a K070786 Gates Micro-V AT and soon as im done installing this short shifter im pulling off the skid plate and tensioner and installing the new belt... altho beware the belt is a reinforced belt and lists for 64 bucks... i got mine for 28 shop cost which is still alot for a belt imo

jpit · 09-01-2009, 01:13 PM

I was looking at the K070786, also. Please let me know how it fits. Did you put on the alternator pulley?

Moemeister · 09-01-2009, 02:54 PM

so i got the new belt on and its perfect within spec and everything... and yes i have the alt pulley on it also.

well tyvm nst for the pulleys i do like them they work as good as they should but for further 370z customers i would either recommend to them a new belt or sell them one with the kit... i have pics but cant put them up till im home this cell phone is a pos... BTW Thanks for the package of m&ms with the pulleys they helped me through the install :-P

Brazilbro · 09-01-2009, 04:40 PM

Do you get a choice of peanut, or just Regular M&M's?

jpit · 09-01-2009, 05:32 PM

Mine were peanut. Is changing the belt a two man operation or can it be done by one?
How do you hold the auto tensioner back? Thanks.

Moemeister · 09-03-2009, 11:35 AM

ya mine were also peanut which is cool since thats my fave...
and the tensioner thing i did it myself from underneath the car and it took some maneuvering to get it on but i would polly recommend two people one up top the other below... makes it easier for the ac compressor and pas pump
