It is not listed on the Vortech site yet, but the specs are almost exactly like the
V-1 Ti.

V-1 Ti Supercharger | Vortech Superchargers

The main difference between the T-1 and T-2 is that the T-2 has helical gears instead of the straight and is quieter.
It has a little higher CFM and max RPM rating ... it also has a larger input dia. and is 75% efficient.

According to Bobby at CIN Motorsports it will bolt right in to the Stillen Blower Bracket perfectly, but since it is slightly larger it may need some fitting/clearance.

Should put out about 3 more psi than the Stillen V3 with the upgraded impeller...which produced almost 12psi on my car.
That theoretically would put it at 15psi without doing anything else (for built motors only)

Speaking of the Blower Bracket ... Any chance that the Stillen guys could redesign/strenghten and/or brace the bracket ?
Read somewhere that a 2 piece sandwhiched bracket was more rigid and didn't flex - reducing or eliminating belt slip - and that can't be a bad thing.

Motor's almost ready to ship from Import Parts Pro.

Should be wrenchin' on it again here shortly...

...

This is what the guys at Jtran came up with to strengthen my bracket. It was flexing a lot at 15+ psi. This bracket cured it.

Awesome !
Will contact Jtran ...
I see you have a cog system...
Can you turn me on to those part numbers as well ?
Did you have to change out the BOV to handle the 15psi?

Pro4Jackster · 09-19-2014, 10:21 PM

I ordered everything from Vortech except the idler pulley for the cog belt. Jtran had it built for me. They kept the machine shop drawings for it in case anyone else needed it. I don't have the part numbers anymore, I got rid of the Stillen kit early this year. But, I got pretty much everything from NutNMuch and Mr. Squeeze.

Edit: I think they are in NutNMuch's Journal.

You make it sound easy. I hope someone does have the funds and patients to make one work.

It did make 11.9 lbs of boost with the 9 lb. pulley

On mine I was seeing 12 also, Stock 8 PSI pulley tho, An my boost was building way sooner right around 3k all the way to redline.

The only change I have made to the kit is replacing the Stillen heat exchanger to the larger frozenboost one. Lowering the intake charge as much as possible never hurts and glad there is an option for this. I love my stillen kit a lot and very happy with it but the only thing I would change is the heat echanger since it relocates to the front end/looks awesome and helps keep things much cooler.

ouch ...

Just checked the Vortech specs for the V-7 and it states that it is only available in CW rotation.
I don't know if that has changed or not...it may have tho' since the Vortech site hasn't even been updated to show their new V-2 Ti.

The V-7 YSi does have more output and a higher RPM rating than the V-2 Ti and it most likely is less efficient at lower RPM with our motors.

It is also physically larger which might make for a real tight fit.
Wouldn't want to bend or cut up the car too much just to get it to fit in...
Not too much room in there as it is.

It also needs bigger piping than the existing Stillen piping, so that would have to be addressed as well.

I don't ever plan on making 1,000 hp with this car so the V-7 isn't the right choice for me.

I guess I'm just not a Turbo guy ...

1slow370 · 09-21-2014, 01:20 AM

Man i posted up the pn's for both trims of the v7 in ccw rotation, and it isnt that much bigger, and the hp rating on the vortech site is in crank so you need a 1000hp blower to actusly hit 700-800hp. For a built motor guy wanting to get some use out of his new $8k motor why play around with little blowers trying to get close to 600hp when you could go v7 and be done with it. Vortech has the drawings of all the chargers available and the volute on the v7 is like a .5 inch bigger.

Thanks for the update ... I had spoken with Bobby at CIN Motorsports with my plans to upgrade my SC'r and he recommended the V-2Ti over the V-7 for my application.

He had built a car for a client with the V-7, utilizing his own custom designed and manufactured blower bracket (to reduce bracket flex) , along with his own custom designed intake manifold and piping.

I would've gone for it then and there but he wasn't ready to sell it all as a package kit citing that it wasn't perfected to his liking just yet, and therefore still under development.

Have you seen CIN Motorsports 370Z Supercharger kit

He also told me that the V-7 was overkill unless I (like his customer) were planning to make 1,000 hp...which I wasn't

Thats when he told me of the V-2Ti and that it would 'fit right in' to my already existing Stillen set up, with only a few tweaks needed.
It would easily make 600 to 700 hp.

He did strongly suggest the the Stillen blower bracket be braced or reinforced as it would want to flex as the boost headed up towards 15 or so.

He also recommended the Gates Green Stripe serps as well.

All this free, friendly, and informative info from a man who was in the middle of race season and knee deep in deadlines.

I trust his advice, he's a man that's been there and done that.
And the more I thought about it, the more it was the logical choice.

If he ever does come out with that kit of his and he is satisfied enough to put his personal stamp of approval on it, I just may have to 'upgrade' once more

Interesting! let us know how you go with the SC'er swap

are you planning on e85 as well?

Will be putting it all back together hopefully starting in the next 2 weeks.
Still expecting some of the usual 'unforseen' delays along the way tho', but hopefully I will be able to get it to the track before the season closes.

I'll post when it's all finished.
No e85 in this area consistently so it will be tuned for 93.

Hope you are having fun with yours !!!

soo there we go v7 confirmed working, I would rather use a unit that I KNOW will be able to make more than enough power, and pulley or restrict it down to the power i want instead of trying to beat 600-700hp out of a unit designed for 400. the v7 can come with the hd highspeed bearing set as well so it will be mucho more reliable than the v3 case pushed to double it's designed power. The moar powah you demand from the charger the more it will load the bearings and gears that just weren't designed for it. Hell you can run the v7 cogged straight from the crank to completely eliminate all belt slip.

Not doubting what you say re: the V-7, but there are other considerations to be made.
Bobby's bracket mounted the V-7 lower so that it would have less flex and also have sufficient clearance ... and he did configure the car with Gates green stripe serpentine belts and did not go cogged.
Again, he felt his prototype configuration wasn't perfected and he wasn't going to sell something he wasn't sure of.
So it wasn't an option and with no set date as to when it would be available he recommended the V-2 Ti that would fit right in to my existing set up.
Keep in mind I've had the stock motor blow after the V-3 Si impeller upgrade plus a 'few' other performance upgrades to keep up - at a sizable cost and with no return.
So at this point I'm happy here to get my car back together and running reliably with a reasonable power increase.
I want to get back on the horse, but need to cut my losses as well.
The more you push these cars - the more they require attention and maintenance - and the easier they can break...
Though I do plan to take it to the drag strip, Stillen put it this way; "the 370z wasn't designed to be a race car", and quite frankly, it's been digging it's heels in and making it a difficult project!
Hopefully it will all come together and I will be in the mid 11's before Christmas.
Great talking with you

1slow370 · 09-23-2014, 06:36 PM

So u upgraded the v3 saw no returns except a blown motor, and the plan now is to build the motor and try upgading the v3 again to solve it? Einstien once had a famous quote about that lol best of luck tho it sucks having your car down for extended periods of time.
