4:1. You want the err on the low side for tuning.

Anyone know what the max psi is for that blower?

I mean that it is maxed out in the sense that after purchase of said kit it is going to cost you like another 6grand to safely up the power. hell if you don't change your clutchand flywheel just buying one of those kits is already over the max the car will take. I like to work in terms of the package as a whole. I think 10 psi would be doable as a race tune but i shure as hell would pulley down to no more than 6-8 for regular use. 10 psi is def. meth injection territory to me. hell i'd think of putting meth on an n/a car just so i could run a nitro booster in it. i'd try to find the most oxygenated shyt i could find.

So, i have some questions here for Kyle&Josh@Stillen, are you going to send out the S/C kits with uni-chip or control box just like you did the the old 350z S/C?
Or are you planning to use Osiris UpRev reflash and tune?
Do you thing the UpRev is better than uni-chip for tuning?
And what made you go with that route for the tuning? (uni-chip vs uprev tuning).

RCZ 03-11-2010 08:19 AM

^ You're gonna have to wait for the release like all of us. It should be coming soon.

CinZinnati 03-11-2010 08:43 AM

So, I have a couple simpler questions. Kyle seemed to suggest that if you haven't done anything to your car yet...don't. But for those of us who have, I'm curious as to why there would by any issue with for example HFC's. I understand the headers, but isn't a less restrictive exhaust good no matter what..or is just a tuning thing because they aren't testing the car with these particular types of setups? And for those of use who have the Gen 3 intakes, what's the best option since we gotta rip 'em out :confused:

G Fo12ce 03-11-2010 09:58 AM

If you go Supercharger, I think this is the best option for your intake:HERE

Zsteve 03-11-2010 10:24 AM

arent both systems developing thier own intake, to fit the SC system, Im sure piping is different now. And he said a CBE is fine.

From what I remember Kyle was specifically talking about the headers. Everything else is fine...You will not be able to use your G3's, so you should maybe start selling them soon. Leave whatever exhaust you have on, that will be fine. The thing is that any time you free up the exhaust with headers, hfc's and whatever else, you will see small increments in peak boost. You should be fine either way...I wouldnt worry about it. Specially if you are not getting the CARB kit.

That's the case with turbos, but not with superchargers. Superchargers make their peak boost at rpm redline. They are not "load" dependant like turbos nor will the reduced backpressure on the "exhaust side" change the pressure ratios since there simply is no exhaust housing on a supercharger. ;)

There will be room to gain more power with either kit I'm sure. GTM has already announced that they feel comfortable running more boost with their kit and just like our 350Z/G35 kit ours will be able to run more safely later on.

This will be a part of the press release which will be coming soon. We used a piggy back system on our superchargers for the VQ35 and the VK56 (Titan, Armada) engines but it was not the Unichip offering.

Sorry if I gave the impression that you shouldn't do anything to your car. You absolutely should prepare the car with a cat-back exhaust, clutch and flywheel, suspension, brakes, and more. I just don't recommend installing headers (shorty's or long tube's) until we have a chance to test it. We saw on the VQ35 supercharger that you could lose up to a pound of boost by installing headers. They did improve efficiency though so you would make more horsepower. It was a weird trade off but basically in the end you did not make any more power on the dyno. However, everyone who drove with that setup acknowledged that there was a definite improvement in throttle response.

Basically...We just don't recommend installing headers until we have the opportunity to test them for you.

You are correct. Superchargers continue building boost all the way to RPM redline. However, we have seen where installing headers can drop up to a pound of boost because of the reduction in back pressure.

Exactly... "drop"! RCZ was talking about increase. By the way, the boost drop on your 350Z s/c is is pretty much a screw-type blower issue only as it is an air pump rather than a compressor.

Exactly. We aren't expecting an issue with the Vortech unit but we also don't want to promise anything to anyone until we have the opportunity to test it. One thing we noticed was that the VK56 did not lose any boost with the long tube cat delete headers that we made but it did run a bit lean. The 350Z/G35 supercharger on the other hand did drop boost but the a/f ratio was fine.

Each engine reacts a little bit differently so we're just playin' it safe.

RCZ 03-11-2010 11:45 AM

Oops, thats right, was trying to help quick before I had to run out and was thinking turbo instead of sc. My bad.
