Sounds like it's on a built motor to me.

This is what stillen posted about it on FB.

Built 350z HR STILLEN supercharger 20 psi setup ready to drop in. This is going to be exciting!"

This sounds like a massive build. Looking forward to the results.

I agree, I enjoy watching all of the extreme builds around here.

Im just saying they changed a lot not knocking the build im trying to clarify that the stillen blower isnt going to be able to push that much air as it is. Was the housing changed? Im assuming that the abec7 impellar bearings were used to be able to push it to 57k. I used to rebuild blown vortech units, so i am fairly familiar with them. Any reason why not try to fit the v4 or larger units? Just not enough space in the z? Even the abec7's and 928 impellar would have a hard time with that much air.

You obviously know your sh*t when it comes to S/C which I can honestly say I don't. Never owned one or wanted one. I'm a turbo guy. I respect your opinion and appreciate the information.

1slow370 · 03-27-2014, 09:31 PM

Then again it is an hr so do you know if there is a set of blower friendly cams on it or are they going to tweak the cam timing to try and push the boost up?

Edit: if they are using the stillen v3 and not going over the 52k impellar redline and hit 20psi they will have been the first to get close to that boost pressure with a stillen kit.

Well if they are doing a full engine build and claim those numbers then clearly the blower isn't just a off the shelf v3. Once o&g gives us the low down on this build then we can moan and groan on specifics.

O&G · 03-28-2014, 03:32 PM

Blower was sent to vortech for upgraded wheel, JTran engineered pulley, custom charger support.

Motor: carrillo top of the line steel Hbeams, arias 10.1, cosworth head gaskets, L19s, stock cams.

Its possible we wont hit 20 psí but we will come close and make gobs of power.

Motor running working on minor thing like gauges, etc....

Ill keep the updates comming!

^I don't see 20PSI, and/or the pulley must be non-existent. And/or the crank pulley must be oversized

Why do this on a STILLEN kit? The "intercooler" won't keep up

Hence why I said custom engineered pulley. The car has an ATI dampner on it and it will be on E85.

I also said it might not hit 20 psi but I see 18 happening with the upgraded wheel and guts, over spinning will be the issue.

Also like I said, we will wait and see when the motor is broken in for results.

Why Stillen? Because that's what the customer wanted and at JTran we cater to the customers needs and wants for their platform. Sure if this was a shop build we would have done things a lot different, like put a giant turbo on it!

Either way, they are thinking outside the box and doing something different. Thinking positive > thinking negative but hey, that's what drives us over here!

1slow370 · 03-28-2014, 05:24 PM

6.78IN oulley on the ati, looks like about a 2.75in pulley for the input puts you at 18,500 rpm on the first cog pulley, is there any reduction from that pulley to the charger? thats already 4,000 input rpm over what vortech specs on the factory bearings which is roughly 14,000rpm overspeed.

gabe3d · 03-28-2014, 09:48 PM

This is on a 350z with an FMIC and more complex piping hitting 21psi.

600whp Vortech - MY350Z.COM Forums

I'm sure this build will do very well with great results. Jtran does great stuff. Good luck.

^Church's dyno reads a mildy modded 370Z at over 350WHP

gabe3d · 03-28-2014, 11:28 PM

There is a dynojet result too aw post down but regardless of that it is making 21psi which is the topic of debate
