I should add, to counterbalance all my bad advice above: the obvious professional way to get it off easily is to remove the radiator first so you can get direct straight access to the bolt with a large impact wrench (and a torch for heat if necc).

Has anyone that has installed one of these pulley sets noticed any perceptible difference in steering effort due to under-driving the power steering pump?

Just curious. :)

I think a lot of people ask this and no one has a definitive answer... I have the 20% UD from Stillen and I didn't feel any difference

If you have the NST set, the PS pulley isn't UD, it's the Crank and Alternator pulleys that are lighter...

... You need to sleep more... If the crank is UD, all your accessories are UD

lolserskates

:facepalm:

Dude, read the OP:

-10% + 10% = 0% difference...

Everything else runs at normal speeds. I'm used to being sleep deprived. :tiphat:

And sh0velman asked about Power steering

You need more sleep, LOL

I saw no difference. Voltages are same as stock as well.

Chris,

If the crank pulley is underdriven, everything on the belt is underdriven. They offer an alternator pulley to offset that difference for the alternator, but not for the PS pump. Hence my question.

Hmm, coulda swore "Everything else on the belt..." Included the PS pump.. :ugh2:

:iagree:

I understand that point, but if you underdrive one pulley, and overdrive another pulley, it is my understanding all Other pulleys operate as if there were no difference. It's a system because they're all connected to the same belt.

If you only installed the Underdriven crank pulley, and not the overdriven alternator pulley, yes the entire system would be underdriven. This is the point behind overdriving the alternator pulley.

It doesn't work that way. If the net change is nothing there would be no reason to go under driven
They overdrive the alternator so that your voltages don't drop

Hmm, then my understanding of the belts/pulleys is all fuq'd up. :facepalm:

Under-driving the crank pulley (the one doing the work) decreases the belt speed. Each individual accessory would need its own undersized (over driven) pulley to compensate for that fact.

In that case, I've had my pulleys on for going on almost 35k mi now, and have had no problems with PS or voltage or coolant flow/temps.

I received my kit last week. My main concern would be looking forward to the rev increase. As i know this motor climbs under my expectations a whole lot. Any little increase would make me feel somewhat relieved. Least faster then the slow setting on my wipers blades. Lol
Works getting done @ RT this weds. I'll let u guys know how I make out.

@antfd3s .. when you have ordered your set? did you order directly from NST? i ask, because we have ordered a couple of sets in end of november and still no delivery. on the phone is everytime the answering machine... no response on emails. does this company still exist?

tino

Been trying to contact NST as well with no response. I find this very unprofessional. How can I contact NST.
I see them active on facebook. I don't get it

It took me 2 months to get mine. They sell them faster than they make them.

That doesn't surprise me. I picked my clutch and flywheel from NST. It's not a huge operation. I can't imagine more than a few people work there.

The wait doesn't bother me.
It's the fact that they do not respond to emails or calls.
I hope they get back to me soon.

So NST got a hold of me and I apologies for putting their phone on blast.
But they changed my order and are making my pulleys as we speak. They also mentioned that they are making other members pulleys as well.
Thanks NST for getting back to me.

So don't worry guys. They are trying their best to get everyone orders.

after receiving a email on 4th of march that they will send the parts ASAP, we nothing received also 3 weeks later... i got a headache..

tino

This anything to be concerned about?

Nope, those are just timing markers

Diddy, I think those are marked on purpose, the marks are painted which indicates to me they were marked prior to painting, that is how I received them and they were packed very well.

Yeah, 100% American made, quality and care to a tee, just gotta be patient as they're not Stillen, they're the little guy

Ok I cool - just noticed them and was curious. If its just cosmetic I could care less can't see the damn thing anyway.

Getting this installed Friday! Can't wait and Ill post back!

I'm also getting my pulleys installed Friday : )
I'll tell you guys what I think.
Mine will be installed on a 2008 G35 HR sedan, crank and alternator pulleys.

For anyone who has installed this themselves, is there any way to remove the alternator pulley with it on the car? I was thinking of using a band clamp and a breaker bar.

Also, If I have to remove the alternator, then what is the easiest way to remove and reinstall the pulleys?

I had mine installed but I do know the alternator did have to come out. Not sure about the second question maybe someone else can chime in. Good luck!

Taking the alternator out is the easiest way to do the alternator pulley, unless maybe you had frontal access (i.e. radiator gone). I never completely removed the alternator from the vehicle when I did mine: I got it loose from the car, but then hung it on the swaybar with the pulley facing downwards to impact wrench the pulley nut, swap the pulleys, and put it back in place.

That makes sense. When you used the impact wrench on the pulley nut do you have to secure the pulley or will it just come out?

I was trying to remember, and then I remembered that I probably posted about it in my journal, and found the post there from 2 years ago :) I don't think I used anything to secure the pulley, but here's the details I wrote down back then: http://www.the370z.com/members-370z-...ml#post1069327

Moving into the summer, we are considering a few Group Buy offers. Would the guys and girls here be interested in a limited edition 370Z group buy?!


MIKE @ NST

I jumped on the 2011 group buy, if you ever make a lightened stock sized unit for supercharged applications, I'll throw money at you :)

Bump for an awesome product

In for a GB.

Thank you guys! Details coming soon.

Now Stay Tuned :)


MIKE @ NST

I'm interested in the GB.
