Skunk2’s Ultra Series Camshafts for Honda’s K-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Ultra Series Camshafts are manufactured from proprietary, high-quality forged tool steel cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics.Up to 80 hp gains with Skunk2’s Ultra Series line of camshafts, Skunk's professional line of high-lift, racing camshafts for Honda’s K-series VTEC engines. Ultra Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power moved up the RPM band. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2’s Ultra Series. What's more, Ultra Camshafts are also the perfect addition to any high-output, turbocharged engine.
Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of forged tool steel core, increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.
Skunk2’s Ultra Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response from idle to redline. AMAX technology simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power. And thanks to Fast Ramp, the same technology used in Formula One racing, seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.
Skunk2 camshafts designs are the direct result of our years of drag racing and road racing efforts. In addition to each Skunk2 project car and race vehicle, the world’s top road racing and drag racing teams have relied on Skunk2 camshafts for years.

Satisfied with color and fit
Size: Small, Color: Light Purple
For the money, this is a good shirt. True, the material is a bit thin and there is a feeling of 'fragility' (loose threads here and there) but the color is nice, the texture is appropriate.
The sizing is what I call "New American". I was a medium my whole life but supersizing has made me into a small. I haven't changed, Americans have grown bigger.
I am six feet tall and a bit (180+ cm) and weigh 155 pounds (70kg and a bit).
The small fits me just fine everywhere but the shoulders are just barely wide enough.
If you have slightly wider shoulders but are similar to me otherwise, this may be too tight for you in that one place.

Fits too tight at waist.
Size: XX-Large, Color: Wine
Quality of product satisfactory, however size labeling incorrect. I ordered a XXL that is too tight at the waist. It should be labeled XXL Trim.

A Classy coat
Size: Medium, Color: Black
For the price I paid, this is a great find. The quality of the fabric was good, and the waist was good. We tried washing it for the safer side, and the color didn't turn out well, but it looks great. If you prefer using the tie, it looks very good, and the bow tie was easy to adjust. I ordered another suit, but for the price I paid, this is really good.
With the fitting, the adjustments could be made, and the extra cloth was provided accordingly, which is a good thing. Coming to the waistcoat, I would say it fits properly if you are going with the actual size, as sometimes it varies. Also, refer to the size guide. With the washability, I used hand washing and just dipped it in water to see the color. It was really good and the color sustained well. The tie was not provided, but you do get the bow tie, and it was neatly packed. With pants, the size may vary, and if you have any other pants that could match this color, you can use them. The package was very neat and easy to open. No complaints on the package, as sometimes it will be more to open it. This is for our very special occasion and so glad that it was great.
