Stillen SC - put on your seat belts

[Shamrock]

Hi,
I am from Israel and about to embark on the "Stillen Rollercoaster." My first goal is to put all the Stillen bashers and haters to rest. My second goal is to achieve some very nice WHP and Torque numbers that will calm all of the people sitting on the fence down. I have read everypost out there about the Stillen SC and I am here to prove that this a great, powerful reliable kit. My tuner will be MaxTuning here in Israel; whom, to remind you made 555 WHP on my buddie's GTM SC. I'll be hybriding a little by installing the valvebody upgrade from GTM. Any advice would be greatly appreciated; you guys have much more knowleadge than we here. I have talked extensively to Stillen and GTM and they could not have been more helpful. Put on your seat belts and get ready for the build!!

Specs:
2011 370Z 7AT (30,000 km)
Stillen SC (to be installed)
Stillen Headers and Cats
Akropovitch CBE
GTM valvebody upgrade

Looking forward to see how much power this will put down.

How do you plan top get the WHP that high? I love my Stillen SC now that Stillens tune is off of it but with the 8 lb pulley I'm at 406whp with the 7AT.

I don't know how high it will be in the end but where aiming high.

thanks

I've read that Stillen headers make no difference and I heard from Stillen themselves that Stock headers work the best with their Super Charger. So maybe if you want to save money don't go with that

[Shamrock]

I already have the stillen headers installed. Didn't think enough ahead in the future.

thanks

I have a feeling the dyno tech is gonna errm "correct" the numbers on this one
Well you have one thing going for you in that it's a very high reading dyno. Best of luck though. The kit will need some significant upgrades to push over 450whp.

Experience will show you.
mods deleted my first post.

good luck op. Simple research will prove u wrong.
This will end with inflated dyno numbers or most likely you will begin modding the hell out of the kit and still not make it.

Gtm kit will make the power u seek easily.

EDIT... I thought this was a welcome thread, lol

Lol, don't beat the poor guy down!!!

Welcome brother! Good luck!


And we've been getting a lot of new Israeli members recently. Do you all know each other?

I don't think it has anything with being a believer. It has all to do with facts, design, and knowing what needs to be done in order to get the kit to make the power you are after.

For starters, install the OEM intake manifold back on the car, and get rid of all the water-air cooling that comes with the Stillen kit. Figure out a way to install an air-air front mount intercooler with a single inlet and dual outlet. Get a shop to fabricate some charge pipes that are 3" diameter, and have a good 2' section of this diameter tube before the TB's. Weld two MAF sensor housings on each 3" charge pipe, again before the TB's.

At that point, you will be ready to put it on the dyno, and see what that Vortech supercharger can make. With those mods, you should be able to hit your power goals.

Bottom line, you can't argue physics, and the proper way of going about this when it comes to making that kind of power. Also, remember that the head unit (supercharger) will rob about 40hp from your engine in order to make the boost you will need (12-13psi) to make that much power (500 at wheels)...AND the auto won't help.

So for you to make 500whp, the HP at the crank will probably have to be about 640. The blower is capable of 1150cfm, and this will be right on the limit of what it can do.

Not trying to be negative, just suggesting what you should do if you wish to do this properly, right out of the gate. That is what I would do if I had this kit, and wanted to push it.

I believe in the kit and I love what it did for my car but if you get caught up in those numbers it's going to let you down. If the Boosted Performance kit worked with the 7 AT it would be on my car simple for their attitude about customer service!

Welcome - sounds like you have a fun project planned.

I'm new to Z's - but have lots of experience with Vortech blowers.

Have any of you looking for BIG power tried stepping up to bigger headunits? I used to run a YSI trim V-7 YSi Supercharger | Vortech Superchargers

The YSI is 1,600 CFM and capable of 30 lbs of boost at 65,000 impeller speed.

I was pushing 21 lbs of boost at only 6,500 rpm with big cams, LTs and ported heads in my Mustang 4.6L race engine ...

Not sure where the boost limit is on the 370Z motors though.

There are other big Vortechs out there - any try one of them on a 370Z?
