Overview:

Holley's Mid-Mount Accessory Drive System is now offered for the serious racer in mind. If you need a front drive system for your LS engine racecar, they are now available without air conditioning and power steering depending upon your needs! Holley's Premium Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design (Patent Pending), where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable Type II P/S pump with baffled reservoir are also integrated. The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines. When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, Alternator, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation. The Premium Mid-Mount system comes with dress up pulley covers and an SFI certified damper. Partnered with this damper is a billet 6061-T6 aluminum hard anodized crank pulley. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Best frisbees I’ve found for an active dog
Pattern Name: Assorted, Size: 9" Pack of 5, Pattern Name: Assorted, Size: 9" Pack of 5
My dog is an ACD/Border Collie mix, so he is absolutely obsessed with anything that flies or moves fast. We’ve gone through a lot of frisbees over the years, and these are the ones I keep coming back to. They fly really well once you get used to them, and they’re soft enough that I don’t worry about his teeth or mouth the way I do with harder plastic discs. They also hold up surprisingly well considering how rough he is with toys. Mine get used constantly in the yard, at parks, and near the water, and they’ve lasted much longer than most dog frisbees I’ve tried. I’ve bought several packs over the years, but honestly most of the damage has happened because my dog likes to lay down and chew on them after playing fetch. If I leave one sitting on the ground too long, he’ll eventually destroy it. That’s not really the toy’s fault though. In some ways I actually like that they’re soft and flexible enough for him to comfortably carry around and chew on a little. Another thing I appreciate is that they’re washable. After a muddy or slobbery session I can just rinse them off and they’re good to go again. For an active dog that loves chase and fetch games, these have been excellent.

Very durable
Pattern Name: Assorted, Size: Pack of 2
Awesome frisbee. Even if you don't have a dog! It's actually just nice to play with as people! Flies great. Left alone a dog with l can destroy it. It's not a chew toy, but it is a great game of fetch. Perfect size for medium and large dogs, plenty durable.

Very durable and amazingly fun
Pattern Name: Assorted, Size: Pack of 2
My dog loves frisbees, but now this is the only one I’ll ever buy again! If you’ve ever had a dog frisbees you know that some dogs can eat/chew-up a frisbee in literally minutes. Not this one, no way! I’ve bought several of these because I keep one in my truck, one on my boat, one for the backyard, and one just for the dog-park (can you say “community drool”? I take these everywhere (see videos) and every single dog that gets ahold of it loves it. As a matter of fact the only problem I’ve ever had with it is when I take my dog to the dog park all the other dogs fight over this frisbee. As far as quality it’s tough as nails, sure if my dog sat and gnawed on it for hours he might eventually tear it up but it would take a very long time and I would see him chewing it up. My dog and all the other dogs at the dog park will gnaw and chew on it and not one dog (from labs to retrievers to pitbulls to Rottweilers to even a malinois, a German Shepard and a massive cane corso to a little cur of a dog) not one has torn it up, and they ALL play tug of war with it. It’s great for teaching young and old dogs how to catch because it is soft enough not to bounce out of their mouth and they can catch it with a good grip. The best thing ever: it’s malleable and can be easily put back into a round shape even after heavy pulling. It floats on the water perfectly and will not sink no matter how wet with water (or drool!). On top of that it’s very light yet is easy to throw in even heavy wind, and as a frisbee guy for decades when I say it throws good, it’s pretty darn accurate whether wet or dry. Personally I have found I like the pink one the best (not the pink swirly one, even though it’s fine I like the black edging on the others as they seem tougher and more solid for throwing). The solid pink ones are easier to see in water, grass, dirt, etc. I have bought 5 of these so far, not because they get trashed or fall apart, but like I said it’s because I have one for every purpose. Highly recommend the solid pink as best color wise.
