The Kraftwerks K Series "Race" Kit is built for the hardcore K engine builder. Centered around the highly efficient Rotrex C38 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.

Didn't stand a chance.
Size: One Size, Color: Georgia Bulldogs
I didn't know what to expect from this dog toy. I really just wanted a football style toy that we could play with our puppy with, especially during the NFL and college season. We had the toy for one week. I don't know if the toy is poorly made or if my puppy is just a master at destroying everything he puts in his mouth. In any case the first day the rope was ripped from the ball. The next day all the stuffing was all over the living room. The third day he broke the squeaker. By the end of the week the toy was missing most of the rope and what was left was frayed and way shorter than when we first got it, the football itself was flatter than Tom Brady's from deflate gate and just looked like this sad little piece of cloth and resembled something that had been abused for years. I will say he did really enjoy playing fetch with it for the short time he had it. Don't think I'll be buying another. Can't stand to see another toy get abused like this one.

Lasted Less Than Two Days
Size: One Size, Color: Tennessee Volunteers
This is a terrible quality toy! In only two days the seams were busting open and stuffing was all over there house. This was purely a fetch and recover toy. There was not tugging, chewing, or pulling. I am so sad for my dog. He was loving this toy, but because of horrible material and quality it 48 hour tenure has landed it right in the trash. "Tough quality..." do not waste your money. I would give this zero stars if I could.
