Come Play With Power

Looking to increase your V10's power output? Take a look at the Active Autowerke Signature V10 Power Pulley kit. It comes mostly with everything to make this installation simple and easy to install, it is also reliable and trouble-free. Best of all, it makes horsepower.


Purpose

When working on the BMW S54 engine of the E46 M3, Active Autowerke has found that additional horsepower can be attained with the installation of power pulleys. The S65 BMW V10 engine is no different where it also has to drive components like the the air conditioning and power steering. These ancillary components actually take away power because they create a load on the engine since they all share the same drive belt design. Active Autowerke has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. The end result is unleashing untapped power just by redesigning the the drive ratios of the engine pulleys. An additional 12+ horsepower is measured on our in house Mustang dyno when compared against a stock BMW V10.

What was a solid block of T6061 billet aluminum will now be transformed into precise component with a calculated pulley diameter, proper groove pitch, and true belt alignment with a calculated pulley offset. The exterior is also treated in a hard, black anodized finish that is strong and durable to give a smooth and quiet operation that will be trouble-free.

All the necessary parts are included in the kit making for a relative simple, easy installation that looks similar to factory when installed and it makes power. It can be fully reversible back to original if the need arises.

The power pulley is very modular in design and complements very well with other Active Autowerke performance products like the Active performance software or the Active performance exhaust. Truly a good start for the BMW M enthusiast.

Tuffy Desert Phrog vs Lola
Color: Green Leaping Phrog, Color: Green Leaping Phrog
Just a little background about my dog. Lola is a 5 year old corgi-terrier mix with jaws of steal. Lesser stuffed toys have met death in under 5 minutes. Tennis balls last less than a day. Rope toys that do not have frayed ends might possibly last a week (frayed ends never stand a chance). The only toys that she has not managed to destroy are her Kong, a Kong bone, and a racquet ball. I figured I would document the life span of Phrog (Tuffy Scale: 9) before making my final judgement on it’s durability. Day 1 - Phrog Arrives! Lola was very excited about the arrival of Phrog and immediately went into destruction mode. Phrog did sustain a little damage before we were able to bribe her to drop Phrog and get her understand that he was more fun to play fetch with than to mutilate. The white you see in the picture is not stuffing, but the second layer of defense for the toy. The fact that my living room is not full of stuffing and I didn’t have to pry a squeaker out of my dog’s mouth, I’d say Phrog wins the Day 1 challenge. Day 9 - Phrog has sustained a little more damage, but not anything life threatening. His side wound is a little bit larger and one of his eyes is half ripped off. For safety reasons, I am going to finish removing the damaged eye and some loose thread from various places. Other than that, Phrog is still holding up and holds top toy spot. I have also found him very useful for dealing with anxiety; the squeaker can often distract her from her stressors and Phrog takes the abuse of her frustrations. Day 16 - Phrog is starting to show signs of mortal wounds. Lola has made it through the thicker layer around his arm and I can see the stuffing. It is only a matter of time before gets all the way through. Day 60 - Phrog still lives!!! I have done some surgery on Phrog to reinforce the fabric around his arms, but Franken-Phrog is still the favorite of all of the toys. She will even get brave enough to rescue Phrog from the evil vacuum when he is kidnapped and tortured. I am thinking about purchasing Phrog II for the inevitable day when Phrog goes off to the pet toyland in the sky, but for now, there is only one Phrog for Lola.

Long lasting play toy!
Color: Multicolor
Tuffy toys in general are great and they are a pretty good deal on Amazon. They are not indestructible, and if your dogs use them as chew toys they will eventually break through. My dogs have had this Armadillo since Christmas (and they do chew on it some) and the only thing missing is an ear. They like to play tug-of-war with it a lot. This is a bigger toy, but even my forty pound dog plays with it. I would not recommend this toy for dogs smaller than Border Collie size. You can make these Tuffy toys last longer if you don't allow your dogs to chew them--when your dogs starts chewing on non-chew toys trade them for a chew toy and when you catch your dog chewing on a chew-approved toy reward them for chewing. Eventually your dog will catch on and realize that if they want to chew there are certain toys that are allowed for that. In addition to being a great play toy this is a pretty cute toy too!

Not Tuff
Color: Black Yellow Phrog, Color: Black Yellow Phrog
Absolutely terrible and not “tuff” at all. My chocolate lab had this thing destroyed in less than two hours. I would not recommend these for the price.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ Cute but Not Durable Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again. I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!
