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

NickD · 07-09-2013, 08:40 AM

I may be in for a blue set. Is this really under drive or just lightweight? I don't want to have issues with any of my accessories. How much are the belts?

It's 10% underdrive on the crank and light weight. Alternator is 10% overdrive and some minor weight savings as well. I didn't have any issues with anything that was driven off the crank. My voltages stayed the same as stock.

Correct. Our Crank + Alternator combo keeps the electrical system at the same speeds as the OEM pulleys. Tons of info on all of this stuff in the first few pages of this thread. Hundreds of positive reviews from fellow board members in the forty plus pages that have followed.

Thanks. Just wanted to make sure i dont have issues with AC or heat or anything like that since it is my daily driver.

So early in the thread it says you don't need to replace belts but later i see you posted that we do need to replace the belts? If we need to replace them is that price included in your group buy price already or is it additional?

Also, I'm on an automatic tranny. Any issues with that?

Navyboy916 · 07-09-2013, 03:10 PM

I have an auto as well. You will have no issues with these pulleys. They are great. The set comes with the correct size belt already so u won't have to worry about finding the correct size. Check out the pic it fits perfect just make sure you seat the pulley correctly and have no wobble.

I posted the GB on a local Z FB page and this was a question that popped up:

"if the rpms go up faster because its light weight wont they lag to drop?"

Any thoughts?

Yes it revs faster.
If SRM equipped, SRM will hold revs on upshifts too for a small period of time in an effort to make it smoother. Not sure what he means "lag to drop"
If not SRM equipped, revs will drop faster too because of the lower inertia compared to the heavy stock piece.

NickD · 07-09-2013, 08:50 PM

Add me to the list for a blue set please

happyh00 · 07-09-2013, 09:29 PM

Add me to the list please. Gold kit with belt.

pedZ · 07-09-2013, 09:33 PM

Just two more. Come on people, let's do this!

simota1 · 07-09-2013, 09:34 PM

almost there!!!!

Infamous · 07-09-2013, 09:35 PM

I have faith in you, Z bretheren! Let's do this.

NonStopTuning · 07-09-2013, 11:04 PM

I love how this community has people who respond to questions so quickly. Thank you guys for your input and support.

Almost all of these topics have been covered in earlier posts, so I will give you the short versions...

You will need to use a new belt with this kit. We list the correct belt number on our website and you can order the belt from us (additional charge) or you can buy it locally.

Revs will climb, and drop, more quickly when any weight reduction is performed, including pulleys, flywheels, etc. This is a good thing. No one ever complains about a more responsive engine, trust me, you'll want more once you've tried it!

Let's make this happen, ladies and gents!!!
