5000 miles on mine so far and it is working great. Look at how the belt is threaded through the whole drive system. The belt bend radius is smaller at other points than at the top.

Most of us are using the stock jack shaft pulley diameter (the same as shown in the picture) even if running the 9psi setup because we use the Vortec pulley on the SC drive belt side. Stillen 9psi pulley = $200, Vortec 9psi pulley = $90.

Lookin good. Go beat on!

Sweet!!!!!

Your gonna' love it!

BTW: save up for replacement rear tires.........

Off topic but interesting.

The International Model Power Boat Association (IMPBA) is holding their International competition in Huntsville this week. Wow, these RC boats are FAST!

The most amazing record was for the 1/16 mile drag run. How does 1.3 seconds at 163MPH sound! This was done with an electric powered boat. The high nitro boats are running "only" in the 130MPH zone.

I've got the regular 8psi pulley in the front side of the jackshaft as well. It's tight for sure. In fact have to be careful, I got just a little bit of water on the area doing some cleaning the other day and it was enough that it kicked the belt right off.

Was going to grab a 9psi pulley, just to clarify it sounds like the Vortech one goes in the SC backside of the jackshaft where the Stillen one goes on the front. Correct? I hadn't contemplated there would be a difference but stands to reason there is I suppose.

I actually had one before and wasn't going to use it so I sold it. Which of course I now regret.

ChaseZ, You are correct. The Stillen 9lb pulley replace the silver 8psi pulley (jackshaft) on the serpentine belt side. See attachment.

Thanks

Does anyone know where you can get a Stillen 9lb pulley?
conceptzperformance.com just ran out.

Stillen 9lb pulley is 2.75" 7 ribs from what i have seen on other forums. Correct me if i am wrong.

So I would need to find a similar pulley. Maybe from Vortech. Let me know if anyone finds one please. I will keep looking.

Here's the (Silver) 9lb pulley that I got from Stillen ......

Concept Z performance was selling the stillen 9psi pulley for $90 a few months ago. Then i looked for a customer a while back and they were $120 and i looked just now and they are $195! WTH man.

acorona370 · 06-15-2017, 11:40 AM

Is anyone else interested in a group buy of the "Supercharger System Pulley, 9lb - Nissan 370Z 09+ Z34" ?

Stillen actually discontinued them a couple weeks ago. hence the rise in cost..

ChaseZ · 06-15-2017, 12:45 PM

Ah that sucks.

So just to clarify, still pulley front of jackshaft and Vortech rear?
Others like 928 etc I assume are rear of the jackshaft as well?

TBatt · 06-15-2017, 12:56 PM

I'm using the Vortec 2.95 pulley on the SC. You will also need to replace the SC drive belt idler with a larger pulley to take up the slack. I'll get the pulley number and post it.
