From what I gathered speaking to them, is that the tuner kit will be around 4500 and the full kit including carb will 4999. And also mentioned that it will be 280whp and 200+ ft/lb of torque ( can't remember exact number) on 91 octane.

Im guessing this is borderline clutch replacement... Ill believe it when I see it. Two moths wait for dynos most likely

Looks like an ugly version of the Vortech kit. Curious to see the charts, but to be honest couldn't see myself putting that kit on my car.

I don't know. It makes it pretty clear that this thing has been driven. Inspires confidence.

This being a car show/showcase of product and all I could see this being a little cleaner, I will concede that point.

However, I'd rather see this that probably has not been touched in XXXX miles than a half-assed turbo kit that's not even half hooked up and missing 3/4 of the clamps to hold the piping together like you often see in car shows.

I want to see dyno charts. Peak HP and torque are boring. This torque chart better be as flat as a white chicks ass

The Rotrex SC used in this kit has some fundamental internal differences to the gear-driven SC impeller used in the Vortech kit. The differences offer some key benefits that are unique to Rotrex SC's.

Via Kraftwerk's article: "Not All Boost Is Created Equal"

Quote:
We believe the Rotrex supercharger offers the best aspects of supercharging and turbocharging without the typical disadvantages. To gain a better understanding of why we choose Rotrex superchargers, a brief overview of the advantages and disadvantages of other forced induction solutions is helpful.

Positive Displacement Superchargers (ie roots type and screw type) are relatively efficient (-65%) and work well at lower rpms, however they can only move and compress a fixed amount of air with each revolution. As a result, as supercharger rpm (-14,000 rpm max) and boost increases, efficiency falls dramatically to approximately 50%; meaning only half of the energy being used to tum the supercharger is compressing air while the other other half of the energy is converted to heat. In addition to being noisy, positive displacement chargers quickly 'run out of air' and overheat as rpm and boost levels rise.

Gear Driven Centrifugal Superchargers utilize a centrifugal compressor section, but because of their limited rpm capabilities (-55,000rpm max) they must oversized impellers to achieve the desired amount of mass air flow. As a result, these superchargers are far from optimal and generally suffer from weak low-end torque. Furthermore, like positive displacement superchargers, gear driven centrifugal chargers are highly noisy.

Turbochargers, are exhaust driven centrifugal compressors that can spin at much higher rpms (-100,000+rpm) and can take advantage of the benefits of using smaller compressor wheels to quickly build low-end boost. But unlike a supercharger where the compressor is mechanically driven by the engine and constantly creating boost, throttle response is an issue with turbochargers. Each time the engine is unloaded (ie shifting or closing the throttle) the exhaust tract must rebuild pressure (spool the turbine) before it can sufficiently drive the compressor wheel and build boost. However, the most critical issue with turbocharging is heat. The drive side of the turbo runs at extremely high temperatures (1200*F-1600*F) and is directly connected to the compressor side where the heat naturally bleeds over and raises the temperature of the intake charge (by approximately 30*F to 40*F). As a result, ignition timing and often engine compression ratio needs to be reduced to prevent damage to the engine.

Rotrex Centrifugal Supercharger presents a unique solution that combines the best aspects of supercharging and with those of turbocharging. Unlike any other supercharging solution, the patented Rotrex traction drive allows it to operate at sufficiently high rpm levels (up to 240,000 rpm) to take full advantage of modern centrifugal compressor and impeller design. The result is a supercharger that offers better low-end boost than other centrifugal superchargers, better top-end boost that positive displacement superchargers, and better more predictable throttle response than turbochargers. Also unlike turbos and positive displacement superchargers, the Rotrex supercharger does not suffer from heat related issues. Because the Rotrex runs cooler (lower thermal stress), higher compression ratios and advanced timing can be run thus further optimizing response and power.

Look at the civic dyno posted above or any other rotrex dyno plots to get an idea of what the curve may look like.

Here is one on a 350z motor:

They told me when I talked to them the tune it yourself kit was around 3995 which is a pretty good deal.

All I see here is that we, the drivers, are the winners here

I'm really glad to see another FI kit for us to choose from. I plan on doing FI next summer and was pretty much set on the Innovate kit... now however i'm definitely considering the Jackson kit too.
