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.

Toy provides much fun and hilarity, seam rips.
Size: 20 x 4 x 4 in, Pattern Name: Eggplant, Size: 20 x 4 x 4 in, Pattern Name: Eggplant
So, I kind of bought this on a whim. But our dogs absolutely love this toy, and it provides many moments of hilarity as watching our medium sized dogs tote this giant toy around, whipping it back and forth, hitting themselves with it, is constant entertainment. The squeaker is still working nearly 6 months later, which is amazing. I only took off one star because I have had to perform surgery on this toy multiple times due to the seam coming open, letting the stuffing out, which is a major issue. I have to take it away from them (which they hate) then find time to sew it up until the next spot opens up. If I was smart, I'd just have reinforced the entire seam the first time, but no one said I was smart.

This worm, pretty sure it’s a worm and not a snake, can take a lot of abuse.
Size: X-Large (Pack of 1), Color: Blue Snake, Size: X-Large (Pack of 1), Color: Blue Snake
Snake, worm, whatever, my dog doesn’t care, she loves it all the same. My little friend can be kinda rough with her toys. This is no exception. The pictures are from roughly one month of giving it to her and include playing with it at least every other day or so. The top is holding up well, but the bottom has taken some damage, and two of the squeakers have long since been destroyed. Despite this, my dog still loves playing with it. We normally play tug of war together, but on her own she chews at it to get to the squeakers inside, which she promptly destroys, which I’m totally fine with, as quiet toys are much preferred, by me, not her. I believe there are 4 in the XL size that we got. We’ve had a few of these in the past. We tend to get about 6 months out of them. After she “lovingly” removes the squeakers, she doesn’t chew on it much, and we just use it for tug of war, but at that point she’s done enough damage to the underside that its time is limited. But, as it’s pretty low priced, for the time and enjoyment we do get out of it, it’s very much worth it. I do need to clarify, the durability is actually quite good, I don’t fault the product as at all, it’s just my dog is equally as good with destruction, but it should be noted this toy does last much longer than most of her victims. The color, (we got the blue and green) is also very vivid and nice, as is the texture. We’ll be purchasing again.
