Oh, I assumed you blew it up. It is going to be interesting, I never considered uping the psi before BP and evohunter started this project.

Just measured my pullies

Stillen 2.90"
Jackshaft 3.20"
SC 3.20"

With impellar upgrade this is supposed to see 12psi sea level

I cant see a 2.45", 2.75", and 2.70" making anything under 15 but I havent calculated it.

I tried to keep the front serp pulley as large as possible for better belt wrap and leverage. It only has about 30 degrees of wrap to work with. Wouldn't it be better to carbonite coat the 3.12" stock serp pulley and use the rear pulleys to increase blower RPMs? That plus an impeller upgrade should make 550hp on a 3.7L. I guess it's all just speculation until someone tries it.

Has anyone calculated the impellers rpm? I was reading on 928 motorsport today and it said the vortech is only made to spin 50,000 rpm but they can up that to 60, 000 but I have no idea what it starts at in the Stillen kit.

Go to vortech's website. Click manuals and tech info, impeller speed calculator, then fill out the info for the V2/V3. It's about 49K RPMs as Stillen sells the kit. There are multiple people on the 350Z forums turning their vortechs over 60K RPMs for years. Then when the bearings fail, send the unit to vortech for a rebuild or trade up to something better.

There are high speed bearings available for the Vortech:

928 Motorsports - Premium High-Speed Ceramic Bearings for Vortech® Superchargers

I would take some time and try to get as much of the belt around the drive pulley on the jack shaft as possible. This may involve some customizing, but would go a long way if one is trying to push this blower.

$500 for bearings rofl, wtf

ive calculated that with my 2.75" on serp side, 2.75" on jack shaft and 2.70" on blower - 52344 RPM

Are you going to do the higher rpm kit or leave it as is?

I tried removing the intercooler inside the manifold, it wont come out inless I remove the manifold... I don't want to do that this year lol. :(

Ill leave it as is. Vortech says it can spin to 52000Rpm.

Ill wait and see what kind of boost I get with this setup and go from there.

I would get that thing out of there. It is going to cause some pressure drop but worse it will become a heat soak. It is going to get really hot under wot and when your stopped it will retain a ton of engine bay heat. Then when you go to get on it again it will just blow that hot air into your intake. That air will be unmetered also so you are back to the same problem of your car is thinking its getting cold air but its not and will not retard timing.

But maybe I'm being paranoid.

?? paid $275 for my impeller upgrade from Vortech ?

I am confused. I just spoke with them and they said it will max at 53K and they helped me through the calculator on their site. Even though it says teeth count, you can use diameter. Here is a snapshot of my setup. I'm already over the recommended with some larger pulleys.

I can pull it out about 3 ", I just didn't want to cut it right there.

but I think im gonna have to :(

Got the intake manifold off, If you have a 12mm EZ-RED 21" long rachett wrench with pivot head, makes the job super easy. Got the Intercooler out, dropping it off in a few hours at the machine shop to have a plate fabbed up!

Nice work! I made my block off plate last night. Going to paint it black.

Really interested to see where this all goes. I had been looking into a Stillen kit already, and this is just making my wallet itch even more.

Gah.

I should get a cut from Stillen's S/C kit sales now....:happydance:

Ha! I sent you a PM, too. :D

Well..Price just went up for used Stillen kits!! :bowrofl:

Wasn't the plan to clock the sc to go straight down? Just curious what changed the plan?

90° doesnt work. But 180 does. This design went with 0 and it worked out great.

I have no problem with the design, just curious why it changed.

Just a clearance issue, the charge pipe would come in contacted with the fan blades. I wanted down 90 but just would not work.

Machine shop wanted 140 bucks to make this piece. way to much!

I went down to metal supply, bought a 5"by5" piece of alum.

Fabbed it up my self, then painted it black with VHT wrinkle paint!

$140???!! Lol!!

Looks just like mine!

Can I ask why you are waiting until next year for that set up? Is it just not being able to feed it enough fuel? I'm asking because I have a return fuel system that could handle it and more but I want to make sure I'm not missing something.I'm looking forward to seeing what you get out of the car when its tuned.

Yep, its all fuel.

I need bigger injectors, and a return system.

I'm going to install over winter and retune next year.

I just want to get everyone a baseline off the air/air system then move up from there!

Winter in Canada, that doesn't sound fun.

lol.. 4 feet of snow and -30 :(

Wow! I can't take +30s and zero snow.

Well at least she will enjoy inhaling this new Air To Air COLD AirFlow!

Wouldn't have to worry about over heating :roflpuke2:

That block off piece looks legit. Don't forget to put a gasket or something on it.

Can't wait to see the outcome of this kit.

Okay guys, got my pipes back from the powder shop. Ill be mounting up tonight.

I received all my pulleys yesterday as well.

Ill post up my findings, The idler pulley on the blower side needs to be changed.
I found one from dayco pulleys, 34$.

the only problem - The bearing is weak sauce. Cheap bearing.
I'm going to universal Bearing and seal today. They have a bearing good up to 100,000RPM - For the set its 26$

ill provide everyone with part numbers and pictures once I tackle it!

Thanks man!

I was thinking a Right Stuff Cooper, gasket maker, Its really good for high temps, I use it on exhaust systems a lot. Should do the trick :)

That's what I used on mine too. :rofl2:
