Aren't the higher stages the non-carb ones? It sounds to me like the only Carb approved one will be the lowest stage kit (stage 0, stage 1, whatever).

I have no clue man? Im sure your right though

The first part I highlighted seems like it could be interpreted either way but the second highlight seem to imply just the "standard" kit will be the CARB kit.

I'm sure Kyle will clarify soon enough but to me that's how I interpret what they've said.

Ok I see what your saying

Awesome!

Thanks for the info, Kyle. Can't wait to see pics and dyno numbers in the coming months.

Mmm mmm. Gotta start saving, so that means no frivolous spending. Gotta make sure I'm ready for this one.

The information sounds good so far. Hopefully, we don't have to wait for the CARB cert to complete before the non-CARB kits are available.

Well Im only looking for another 80-90 rwhp so will the Vortech achieve that easlily? And does the Vortech achieve its power at the higher rpms or lower or what?

Wait, just to be sure, this is going to be a centrifugal unit and not those twin-screw ones they just added to their site, right?

VTS Twin-Screw Supercharger Systems Featuring Lysholm Technology | Vortech Superchargers

My guess is V3 as it is the only one with a self contained oiling system in the range that they will be using.

Kyle no love for the G37s?

I believe he wrote earlier that it will also work on G37s, and the VQ35HR 350s.

Must've missed it then, my bad

I'm basically all game for that! I've been waiting for a SC for a while, the first company to pull through, might be the one i'll be jumping on in a heartbeat, we'll see.

Both Stillen and GTM are gonna have good products. It's all about who delivers first for some members on the forum.

We're hoping that it fits on the VQ35HR motor but at this time we can't confirm that. We currently have a 370Z and a G37 in our shop which are both our cars but we do not have an 07-08 Z in the shop. Before everyone goes offering their cars, we don't need one yet! LOL. When we're ready to test the 07-08 Z we will make an announcement.

Is the warranty something only on the engine, or does it extend to the transmission and other driveline parts?

With that, are 7AT's going to be restricted or exempt or anything odd like that?

In addition, I've been thinking of getting F.I. long tube headers, and I already have their catback.

While I know you can't say 100% that it will work with other brands of aftermarket exhausts, will it be something of a show-stopper with adding a S/C?

I would be extremely surprised if they covered your motor...Im pretty sure the guarantee is on their kit...like if something fails. Not your motor.

Its a supercharger, not a turbo therefore your headers/exhaust are not modified. 2.5" piping from the FI stuff should be enough flow to work great with the SC.

Those are my guesses, but Kyle will answer you im sure.

The warranty right now will be on the kit components. Whether or not we extend that warranty to the engine depends on what we can work out with the insurance companies.

On the exhaust. You can prepare your car with a cat back but I would not recommend buying headers yet. In the past we have found that a supercharger can lose a pound of boost or so because of the decrease in back pressure. Until we can test the supercharger with the headers I would recommend not buying any brand of headers.

That is good info. Does this also apply to High Flow Cats or test pipes as well? I just jumped in on the Berk GB #2 and was looking to get their HFCs also. Thanks again for the info.

THanks for the info Kyle, this will keep me interested for some time now :tup:

I am also interested in this as well. I bought the Stillen CB and HFC's in June for my Z. Will these mods have any affect on the initial tuning out of the box?

The hi-flow cats won't make much of a difference and we definitely plan on making them part of our tuning packages.

Headers can decrease boost on some types of superchargers but we're not sure yet what effect they will have on this kit until we test it. I just want to make sure that everyone is setting their cars up for easy installs later so I'm being a bit cautious with what I recommend right now until our testing gives is completed.

Hi-flow cats won't decrease the boost but they could make the car run a bit lean. We will have a tune though to allow the use of hi-flow's. I don't know how long all of the tunes will take to compile but I imagine it won't take long.

It does help that our project 370Z that we have been messing around with the tuning for the past week does currently have the intake, headers, exhaust, high flow cat combination. And that is the car that we plan on using for our Z supercharger development. Currently the kit is being built on our G37.

Again, very useful information. I may just go on a pick up the HFCs. Now I am wondering if I can get away with picking up a Gen3 and still be good. I will be watchinig this thread closely now. This will be the first F/I kit that I will purchase, so I am kinda out there a bit. I am used to turbo setups and have only purchased intercooler piping kits, if you can call that a kit. So really this is new territory twice over for me.

Kyle, I like everything your saying here. I have everything mentioned except for the HFC's. I don't necessarily like what you are saying about headers losing a pound of boost though.

With the set up that I have, should I be worried about not being able to use some of the aftermarket Stillen stuff? or do you think that it won't be an issue?
-Thanks

:tup:

I can't wait to see the information released...

Vortech or Rotex???? Please tell me if I am right? Both offer little low end torque/hp. (which the 370z could use as much as it can get) Both kits for other cars like the Mustang cost around $5K? Both are good for long periods of use and will last many, many miles? Which is better?


So GTM is using the Rotex and Stillen using the Vortech.....Who do you go with??
John

Losing a pound of boost doesn't necessarily mean any power is lost. A supercharger at a given rpm will put out more cfm at a lower boost pressure. If back pressure is reduced by use of low restriction exhaust components, then one would expect more air to enter the engine. More air along with appropriate amounts of fuel should yield more horsepower.

Is the intercooler going to be built into the intake manifold?

First off, I completely see what you are referencing when you mention the Vortech units on Mustangs and Camaro's and Challenger's...However, the 370Z and G37 is VERY different than those cars.

For starters, the dual throttle body design has caused us to make some pretty drastic changes and that in itself has required a lot of creative engineering. One major difference between our supercharger system for the Z's and G's when compared to Vortech's supercharger system for the Mustang's and Camaro's is that we have had to design a new intake manifold. On most of the Vortech kits they are able to re-use the factory intake manifold which greatly reduces cost. Unfortunately on the Z and G, that was not a possibility.

I think the Z has good low end TQ in the first 3 gears and it climbs the rpm range quickly so the TQ should come in quickly. Where I find the Z lacking a bit is in the crusing range and then jumping on it. It doesnt pick up as good cuz your in a fairly low rpm (7AT anyways). So of course you have to jump down a gear or two to get it TQing good. So which type of SC would be best for this?

You are correct, in the past we had customer's install headers and they saw a drop in boost but because of the more efficient exhaust flow they did not necessarily see a loss in power. In fact, many times people reported that the headers felt like they improved acceleration.

With that being said, because we are in the very early stages of all of this, I am simply going to recommend not installing headers until we can test them.

I have 2 more questions for Kyle:

Will the newly designed intake still have the dual throttle bodies or are you modifiying to have just one?

Also will the air to water intercooler use its own water resovior or share it with the engine coolant?

Yea, to keep costs down and to simplify the process we have maintained the factory throttle bodies.

Yes, the coolant for the engine will seperate than the coolant for the supercharger.

Really appreciate the updates Kyle!

you guys didn't want to just use a y pipe?

Is the intercooler going to be big or small???

If it were that simple we would have LOL...Unfortunately it would have been much more challenging than that. When we release the final pictures I am positive you will be impressed the final design. It is very well thought out and looks absolutely stunning!

I'm not sure if I understand this question and if it relates to the aesthetics of a larger intercooler or the efficiency? I will do my best to answer both examples.

When you see a large intercooler on most turbo cars it is because most turbo cars use air to air intercoolers and therefore they require a larger intercooler. The air is compressed through the turbo where it heats up due to the compression, then to cool it back down the air is blown through the intercooler where air travels over the intercooler thus cooling it down. Because of the volume of air traveling through the intercooler you must use a larger intercooler so that you do not restrict the airflow.

An air to water intercooler system does not require as large of an intercooler because you are only trying to keep the liquid inside the intercooler at a lower temperature. There is not a large volume of air traveling through it going into the engine so it does not really matter how large it is. As long as the coolers you are using maintain a low enough coolant temperature, you're good. I have literally watched our engineers do dozens of dyno pulls on supercharged cars before and immediately pull the cap off the water reservoir and stick their finger in the coolant and it is still very cold.

Basically an air to water intercooler circulates the coolant in a fashion very similar to that of your engine coolant. It travels through the radiator aka heat exchanger then travels into the intake plenum aka intake manifold and through the intercooler which is a secondary cooler inside the plenum, and back to the heat exchanger out by the radiator. So rather than using outside air to cool the air as it travels through the intercooler, you are blowing the compressed air through your water cooled intercooler. Because you don't have a large volume of air coming through the pipes and through the intercoolers you do not need such large diameter piping or intercoolers. I hope that makes sense.

This picture is a simple way of explaining an air to water system. You can see the smaller diameter water lines going through the radiator and into the manifold. Inside that manifold there will be an additional cooler which cools the air before it goes into the cylinders.

So basically if your question is in reference to the efficiency/performance of the intercooler, we will be using an intercooler that is specifically designed for this application and will be more than capable of removing the heat from the compressed air. If your question is in reference to see a cool looking (let's be honest, big intercoolers are pretty cool) air to air intercooler sitting in your front fascia, then no. We will not have one that large because we will not need one that large.
