Kraftwerks 06-11 Civic Si Supercharger Kit

The Kraftwerks 2006-2011 Honda Civic Si Supercharger Kit for the 8th generation 06-11 Honda Civic Si K Series motor, featuring the belt driven Rotrex system. This bolt-on system is full feature and all you need to run comes in the box. You can install yourself or have a recommended installer install this system for you. Based off the Rotrex C30-94 blower, this belt driven system gives you reliability, consistent results and power that comes on with less lag than a turbo system. Out of the box your car can get around 340-380hp depending on the header, exhaust and tuning done to the car with 220-240lb/ft of torque. What you will find is a car that can spin the tires in 3rd pretty easily yet still remain drivable around town. Driving the car will have some turbo charging woosh blow-off sounds that a lot of people do enjoy.

The powerband is linear and wide giving you an easier to control throttle but still enough power to really accelerate quickly when the time is needed on the track, course or while moving through the highway. The Rotrex system uses a patented traction drive system to apply power when needed. The kraftwerks kits run cooler, needs less maintenance and you don't need to tap your oil pan since the oiling and cooling system is self contained. This kit retains factory A/C and power steering and the system can be upgraded to reach over 400HP.

"We have personally tested and tuned this kit ourselves on our own 8th Gen Civic Si test car and are glad to answer any question you may have about it." -- HARDmotion Team

HARDmotion Tech Tips: To help you run this kit the best on your 8th gen civic si
You will want to purchase the hondata or skunk2 4bar map sensor due to psi getting very close to max what the stock 3bar sensor can do.
We suggest getting the exedy stage 1 clutch mated to the stock or exedy lightweight flywheel.
If you intend to drag race or run slicks look at the stage 2 Exedy Clutch.
We suggest you upgrade your worm clamps in the kit to a t-clamp, this reduces chance of boost leaks and looks better and is easier to install.

    Ordered this and had questions, emails came responding quickly. Ordered the kit and was at my door 2 days later. Had everything included and in perfect condition. Great working with the team at Hardmotion!

    8th gen SI Kraftwerks super charger...

    Posted by Justin Magner on Oct 22nd 2023

    Great kit. Installed one day and out on the road the next. The kit I received had a 265 fuel pump and no 4 bar map sensor. I thought they came the other way around. So I pre purchased a 340 fuel pump and installed that instead of the 265 since I already had it. The kit is really a one and done deal. Wish I would’ve bought it before doing any other mod.

    06-11 Honda Civic Si Kraftwerks Supercharger Kit

    Posted by Kevin Norwood on Feb 26th 2023

    First of all, I have to thank the team at Hardmotion. They've gone above and beyond to make sure I was taken care of after a hiccup. I was also impressed with the supercharger, everything came as needed. Believe me when I say it's a huge difference.. You definitely hear that whine and feel the pull! Quick and consisted power on demand! This kit feels solid! Even at 6 psi I'm making 361 WHP! (With bolt ons and upgraded fuel system). Still there is room for more power with a smaller pulley and tune on E85. I definitely recommend this kit, don't hesitate and just buy it already! You won't regret it!
