: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??

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.
