STILLEN 370Z Supercharger System - Announcement!!!

RCZ · 03-18-2010, 04:36 PM

Any pics of the kit installed with the hood closed and the new front fascia on? Those are the money shots I want to see

Kyle@STILLEN · 03-18-2010, 04:39 PM

So you want to see a picture of a Z with our fascia on it? LOL!

No, not yet. We're actually doing all of our testing with a stock fascia that we picked up from our good friends over at the Nissan proving grounds in Arizona. We wanted to do all of our durability testing with the stock fascia so that we could make sure airflow was sufficient for all cars, not just people with our fascia.

Hey kyle, i posted a question about the fascia in the thread you guys started in the exterior section, is it in production yet? and has pricing been released? I need one ASAP.

I am going to be finalizing the instructions tomorrow with one of our craftsmen. Then we will be able to finalize the pricing and everything for you guys.

Kyle - not to sound like a broken record, but any videos or sound clips of the blower at idle?

RCZ · 03-18-2010, 05:10 PM

lol basically yes, just want to see the new fascia with a shiny smile.

Change your pad, bro...you could learn something.

So back on track.

Any luck getting some 93?

ahahahahahaha. i pulled you in. ahahahahaha

What about at WOT? Its really hard to get a clear idea from the videos posted so far.

When I first heard about the SC, I was hoping it would sound like a cobra, but since its a different sc, wont sound anything like that. Would have loved the whine.

Which car for the race car? a GTR?

RE: noise made by vortech V3 blower; On Youtube there are quite a few extended user videos of V3 blowers on G35's. In car, out of car, stock exhaust, aftermarket exhaust. It's a good starting point. I'm sure Stillen wants to get videos up on Youtube for promotional purposes just as badly as we want to see them.

RE: Parasitic drag of S/C and revving of engine; Revving of engine is based on (net torque) / (moment of inertia). For those that are not familiar with moment of interia, it is the rotational mass and how far from the rotational center the mass is placed. increasing the distance from center increases the torque needed to accelerate the object. In the case of a SC engine, the bulk of the rotational mass is the crank, pistons and rods. The moment of inertia, though is heavily influenced by the flyheel because of its large diameter. The moment of inertia of the supercharger is low because of it's small diameter, so the supercharger's biggest imapact is on net torque, which is (torque made by engine) - (parasitic loss). With all of this said, off idle the SC is not making boost so net torque is lower than stock and decrease the rate of revving. by 2,000 rpm or so the blower will make some boost and net torque will be higher than stock and boost will build to redline, so the increase in net torque over stock will increase to the redline as well. The end result: near stock revability from idle to about 2,500 rpm, then explosive increase in rate of rpms gained all the way to redline. The sensation of bog is not really "bog." That implies that when you open the throttle, net torque decreases. That does not happen. Torque will increase, but increases at low rpm will not be impressive. You think it's bogging because you're expecting 350 lb/ft of torque and 8psi of boost at 2,000 rpm like you get at 5,000 rpm.

Checking for YouTube videos now. Thanks for the idea. May hit up RedTube while i'm looking at tube sites.

The "bog" (maybe not the best usage of the word, but was trying to portray a mental image) is from when the throttle plate opens until the RPMs start to build. The difference in an N/A car vs the centrifugal SC car is noticable (at least it was on my Vortech'd G35) in this moment as the parasitic drag is at its pinnacle due to no boost.
