The Kraftwerks K Series "Race" Kit is built for the hardcore K engine builder.

Centered around the highly efficient Rotrex C30-94 Supercharger, the Kraftwerks Supercharger kit produces impressive results throughout the entire power band. While unlike any other forced induction system, the Kraftwerks supercharger system provides a linear power curve, torque on demand, cooler operating temperatures, and total drivability. The Kraftwerks supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical 'spiking' or 'surging' associated with turbochargers. This unique, more usable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability.

Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine’s intake air temperature as well as its risk of detonation. Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

Kraftwerks has designed the billet aluminum brackets to mount either the C30 or the C38 line of changers. The bracketry is designed to mount the head unit low on the motor in a similar position to that of the OEM A/C compressor. The kit requires the installer to fabricate the supercharger inlet pipe, charge pipes, and intercooler as well as provide all necessary support parts and tuning. Fits K20A, K20A2, K20A3, K20Z1, K20Z3, K24A1, K24A2, K24A4, and K24A8.

A total joke.
Pattern Name: Cage Ball, Size: Large - 4 Inch / 8.5 oz
I was so hopeful and really wanted this to be as good as the sellers claimed. After all, they boast of a lifetime replacement (a joke and be sure to read the ridiculous terms lol). I have a "pocket pitty" and she loves rubber toys. There is not much I have found that can withstand her force; however, reading reviews AND seeing their warranty, I wanted to give it a try. Typically, I stick with Java wood and XL super dense knotted ropes, as that has been the only thing that can last any real amount of time. Thankfully, she never goes after our stuff or household items/furniture, just her toys. The ball arrived. I checked it over. It looked semi promising. I was hopeful. The design does allow for them to leverage their paw strength by getting it between the rubber bars and then pull with their teeth. Within 3 minutes of her having it, she already had a bar ripped off. Within 5 minutes, she had 3 bars ripped off. Don't get me wrong, she had a blast. But this is by no means strong enough for an actual aggressive chewer. Perhaps there is just not anything rubber that can handle her jaws, but now I can't get a replacement because the warranty only covers if the product is defective. It doesn't cover chewing damage (on any of their products). The advertising is very misleading so be aware. Why a replacement if she will just destroy it again you may wonder? She loves to go after a ball, but now I know she can kill this one, I keep them in a drawer and only let her play fetch with it while supervised. I will say though, I you have a puppy, I think this would be great for them as long as they are not extra large. The material has give, which is nice. But if you have a real aggressive chewer, don't waste the money.

Not indestructible, but is very tough.
Pattern Name: Ball, Size: Large - 3 Inch / 12 oz
My dog destroyed this, but it took a little longer than it usually does. Would love to know how the lifetime replacement works. There is no information that I see on how to contact the seller.
