High-Boost Upgrade Package



Cowl Intercooler Package

Automatic Owners: You can be intercooled too! Purchase the Cowl Intercooler package and specify you have an automatic. The Cowl Intercooler package keeps your intake temps close to ambient and more consistent on those hot summer days.


General KraftWerks Kit Information:
-The KraftWerks kits and Rotrex supercharger have a 2 year limited warranty. This warranty is on the KraftWerks kit components and Rotrex supercharger. Rotrex determines supercharger warranty.

-The Base and High-Boost kits are made to be used on completely stock engine components.

-There is an upgrade path from Base kit to High-Boost kit for MT Fit.

-Any aftermarket cat-back exhaust can be used with the KraftWerks kits.

-Test pipes can be used, but in conjunction with our Injector Upgrade Pack.

-The stock MAP sensor is utilized in both the Base and High-Boost kits. No additional sensors.

-The KraftWerks kits use a single belt in the system. We have extensively tested this serpentine drive, and have verified its capabilities. There is no slippage when using a KraftWerks drive system. We have had great belt life, and no issues with our belt drive's capabilities. Having a spare belt makes it easier when you decide to change your belt. You can change it instantly, and then order another spare or two from us while you drive around on your fresh new belt.

-We include an automatic tensioner with our kit (stock car uses a manual tensioner) to help increase constant belt tension and reduce belt slipping. The automatic tensioner also increases belt life.
We have had excellent wear (meaning low wear), and have had no belt related issues. But we would expect the customer to change the belt a little more often than stock, because the supercharged belt must work a bit harder.

-Intake temperatures drop tremendously with the KraftWerks Cowl intercooler. The Rotrex supercharger already runs low intake temperatures compared to other forms of forced induction. So when we cool already low intake temperatures, we are able to get very close to ambient temperatures. The intercooler package is a no fuss solution. No cutting up your front bumper to fit, no cutting out your fog lights.

-The High Boost system includes a pre-paid shipping box to Hondata. The ECU is shipped overnight to Hondata for its reflash, and shipped overnight back to you. You will not be going through any Hondata dealers to complete this flash.

-Fuel Electronics are always standard with our kits, and require no additional tuning.

-A/C is fully-retained.

-Our kits have no check engine lights and are a full bolt-on system. Your factory OBDII system will work as normal with our kit.

-We will confirm international compatibility once our production pieces our available. We will be sending these pieces to Rotrex partners throughout the world to check Right Hand Drive Fit/Jazz. We believe that we should have no problems. Until then, the kit will be available in North America only. We will get out international testing complete, and then the kit will be available to all Fit/Jazz owners.

-In order to meet CARB specifications, we have used the stock injectors with our SuperCard unit. The stock injectors have been our big limitation, and we have reached the limit for the little Fit injectors on the Base kit.

We will be offering an injector upgrade package for those that want to do a cat-delete, and it will work directly with the Base kit. The Injector Upgrade pack is plug and play, and is a low $399.99.

The SuperCard Electronics (BASE KITS):
The SuperCard is a small digital electronics unit that is able to extend injector duty cycle in boost for the given condition. The SuperCard is not a "basemap" to get you to a dyno or to "get you down the road." Also, the SuperCard really isn't a "piggyback" by traditional standards.

We spend a lot of time testing to get the electronics to work perfect across a whole range of situations; much like a typical OEM manufacturer tests their cars to work across a range of situations. We take pride in our SuperCard electronics and other electronics. We have revolutionized a new way of tuning vehicles.

We use cell-phone technology to make our small SuperCard chips and boards, allowing us to have a compact unit. This makes it simple for our customers to install, and it works seamlessly with the vehicle; at all throttle positions, all altitudes, all temperatures, all conditions.

To produce a CARB-legal product, it has to work. But we take it a step further and not just pass CARB regulations, we make it so it performs on the track, at full throttle, on the street, idling in traffic.

The SuperCard sees injector duty cycle output and manifold pressure. The SuperCard contains proprietary software that is able to determine proper management for all different types of conditions.

The Rotrex Supercharger:
-The Rotrex is small; about the size of the turbo it competes against. It has a traction drive, but is sans the turbine of course.

-The Rotrex drive system is a planetary traction drive system. This patented drive allows the Rotrex to spin to extremely high RPMs. There is some calculated slip in the system, but it is very small. This drive has no cut gears, which allows the Rotrex to be ultra quiet.

-The traction drive system has been tested to over 500,000RPM! Compressors wheels will not live at that RPM though. The smallest Rotrex unit spins at 201,000 RPM all day long!

-It uses the same compressor wheels and housings as its turbo opponents, because the drive system can turn the proper RPMs.

-The Rotrex supercharger pumps its own Rotrex SX100 oil, so there is no need to tap the oil pan or add an oil pump. A small Rotrex reservoir is included, along with a small oil cooler for the Rotrex oil.

-The Rotrex SX100 traction oil should be replaced every 50,000 miles or 2 years. If you are doing some heavy track abuse, I recommend changing the oil more often. The bottle included with the kit will cover your first 50,000 miles or so under normal conditions.

-The ratio in the Rotrex supercharger never varies. The C15-16 and C15-60 superchargers used on the Fit kits have a 12.67:1 supercharger drive ratio.

-The supercharger pulley size changes the speed of the Rotrex, just like any other traditional supercharger.
