Gain an extra 15-20 hp with Skunk2’s Pro 1+ Camshafts, our professional line of high-lift, racing camshafts for Honda’s B16/ B17/ B18 VTEC engines. Pro 1+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power realized at the factory redline. 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 Pro Series. What's more, Pro 1+ Camshafts are also the perfect addition to any high-output, turbocharged engine.

 

Skunk2’s Pro Series Camshafts for Honda’s B-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Pro Series Camshafts are manufactured from proprietary, high-quality cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics.

 

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 newly revised chill-cast, billet camshaft blanks that have 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 Pro 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.

Good value for price
Size: Freo S
Update - returned due to lackluster battery power. It would vacuum on “regular”, and come back to recharge after less than a hour. It’s too bad, because otherwise it was great. This is a pretty good system for the price, especially if you have primarily hardwoods/tile. It’s not great on carpet, and I really need a vacuum with more suction power. It will not remove enough pet hair from my low pile and washable rugs to make the investment worth it. Battery does not last as long as other models I’ve tried. It returns to recharge many times for my 3000 sq ft. I have a multi level house, with multiple thresh holds (home has many additions). I need a vacuum that can save 6 maps. This only saves 3 - which to be fair is typical in this price range. I don’t even know if there is a vacuum that can save 6? WiFi was easy to connect. Not too noisy when running. Seems well-made. Just needs more suction for my needs. Overall this is a decent system for this price point. I need something more powerful so I’ll probably be upgrading.

Not slim
Size: Freo S
Update AGAIN! I have had it 7 months now and it started making a noise like it was stuck on something but theres nothing at all there. Contacted customer service and they said its the brush and lid, so they send a new one. Great. I get it and install it and it makes the noise still contacted customer service again and they said we can send a new brush and lid, i said i just received a new one and its still making that noise. Now they said we will get back to you soon but its been 5 days and nothing. I have contacted them again and still nothing Update. I’ve had this for several months now and theres a few problems beside it being not thin enough to go under furniture. I dont like to set up ‘task’ because its not always convenient at the same time each day so i usually just open app and push start. The problem is that it doesnt do all the rooms even if i have chosen all the rooms it also doesnt self empty unless i go into the app and self empty it. It does sometimes but not always. Now customer service says that i have to set up task, but why?! We should be in control of the robot not the robot of us. Also, you can not send it to a specific spot it missed. If i move my robot over a spot to revacume, it loses its mind and wants to start remapping. I still like that it vacumes well(besides missing here and there) but i do regret getting it. Also it sucks on edges, so i sweep the edges to it vacumes more. Will not keep them in mind for the futre. Received today. Way easier set up to wifi than the coredy. Way quieter too. Its not slim and wont go under my sofas , that was disappointing. It needs at least a 4inch clearance 5 to be safe. Dont recall seeing that in description but i could be wrong . It also doesnt have a way to manually navigate it , either a control or a way from the app. I will try it out since i like the quietness and the sucking power.

Good quality for the price
Size: Freo S, Size: Freo S
NARWAL Freo S — Truly Hands-Free Cleaning! I’ve been using the NARWAL Freo S Robot Vacuum and Mop Combo and I’m genuinely impressed. The 8000Pa suction is incredibly powerful — it picks up dust, crumbs, and even stubborn pet hair with no problem. The mopping function leaves my hard floors looking fresh and streak-free. What I love most is how hands-free it is. The self-emptying base really works — I don’t have to think about it for weeks, and they claim up to 180 days! The LDS navigation is super accurate, and the obstacle avoidance means it never gets stuck.

Not a mop, vacuum only
Size: Freo S
This is really only a vacuum. It is not a mop, at best it could be considered a “dry mop” but that doesn’t really clean floors. Good price, and it vacuums well enough. Doesn’t seem to get stuck nearly as much as my old Shark. I gave 3 stars because half of what the title says it can do is misleading/not true

Budget Vacuum Surprise
Size: Freo S, Size: Freo S
I wasn’t expecting much from a budget robot vacuum, but it really surprised me! I’ve owned a few high-end vacuums in the past, so I was skeptical about how this one would perform, especially given its price. But honestly, it handles my apartment like a pro. The suction power is great enough for my place. It picks up everything—pet hair, dust on both hardwood floors and the rug. The dock is simple to use, and the best part is I don’t have to worry about it too much. Just clean the mop pads every now and then, and that’s about it. The dustbin is large enough that I don’t have to empty it after every cleaning, which is a big time-saver. For someone like me, living alone with little time to clean, the Freo S is perfect. It gets the job done without the extra features of pricier models. If you want a reliable, budget-friendly vacuum, this is a great choice.
