does anyone know the size of the stock pulley or the 9lb pulley we can get with the kit i was going to get the smallest pulley i can to see what the boost and slippage looked like

before going with the cog set-up i mean if slippage is minimal i may not need to change over to the cog set-up but i do want atleast 14-15psi up top

I have a intake tube 4sale, custom made, y bend off the supercharger, the 2 pipes stack on top of eachother and flatin out towards the 2 throttle bodys, its made of titanium, looking for 500.. thats what the steal/labour costed me.
oh yah its unpainted right now, it looks super nice with welds and and the different colours from the weld.. Pm me your number, ill text u some photos if ur interested.
also i have 2 turbosmart bypass valves 25mm, still in box. looking for 145 each, i think i paid over 250 each.

I think the standard pulley is 3.12 and the 9 lb pulley is 2.75 i am going for a 2.8 hi traction pulley which i asked vortech and said it is just sand blasted finish i have a 2.95 in there at the moment and im seeing 9lb up top so i will be happy with 10lp up top with the new pulley

Mr.Squeeze

The stock Stillen pulley is 3.12 the smaller pulley 9 pound you have is 2.75 that's pretty small. That's the reason I did the cog pulleys when I had the kit better grip plus boost comes on sooner ,even better than the 9 pound pulley . Since you have the T trim you would need to switch in order to take advantage if the blower it self . The thing that concerns me with doing this is all the other mods you have to do to the kit I it runs hot . This is the reason I sold mine with my built motor .

The pulleys available will be:

2.62"
2.87"
3.12"
3.25"
3.33...ect

These are right from Vortech, so unless it is a custom pulley, it won't be 2.75".

Also, looking at the spec/flow of the V3 supercharger 500whp+ should be no problem at all with an air/air FMIC. I would get rid of the Stillen water/air cooling system and go back to the OEM plenum. That way you can put the MAF sensor in the proper location, and have a solid S/C kit capable of solid power.


A quick search...

Stillen uses a Vortech V3 head unit: 1150cfm (for an Si, and 1050cfm for the SCi)
GTM Stage II uses a Rotorex 38-91: 1075cfm (I think advertised as Stage II 600hp)

So an educated guess suggests that with the air/air FMIC mod, the Stillen kit would make 600hp. At least this time Stillen picked a good supercharger to start with vs. the horrible decision they made with the 350z.

I don't know how to compare the cog setup to the pulley set up

Like what cog numbers = 3.12 or 2.95 ect
Or what's the smallest you can go on the cog set-up I want 15-16psi once all is said and done

I should not us psi I guess let's just say I want a good 500 to the wheel


And what happen why it's on hold

although the blower can handle higher psi, the intercooler is not adequate to disapate heat above 12psi. If you want the cogged pulley part numbers i can send them to you. But be advised, it's not as simple as removing the old ones and putting these on. it may require some customization like spacers and small adjustments in addition to requiring a re-tune.

Man i just read this entire thread ..i was hoping to see the outcome and base my decision on whether or not to go FI off of your results

ANMVQ

For the reasons why Osiris said the Dealer can not figure out how to set up the pulleys there was alot of back and forth between them and I , Pics and what not, There are saying the belt wants to walk off??? Idler has to not be set up right and they did not install the heat exchanger( Said they cant) so I'm going to pick the car up today and either finish myself ( Which I should be able to) or send it to my tuners on Next Friday VIA tow truck, I just how I can drive the car home, 45 Mins ?

Pretty much not a happy person right now,

So Kazien already fixed the belt issue( yesterday) was WAY to tight. So much that the when the relaesed to the proper setting it hit the head( Yes Cliff) the dealer did not do it right, of course, AN the torched the bearing in the idler pulley, I need another one . The rev'd the car up pretty good on the lift and did not get any belt walk, They will be removing the bumper today an installing the heat exchanger and MAF's then off to the dyno tomorrow or Thursday we hope.

Is your warranty voided by you adding those parts on the stillen sc? And at the dealer?
