Flowkooler's pump 1688CI for the small block chevy Corvette engine has a 16 blade skip vane impeller that is CNC machined from billet aluminum.  An increased vane count and a reduction in the plate-impeller clearance achieves greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps.  It is then surface coated with a military grade type II Class II anodized finish. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot small block engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

An Exceptionally Well Designed Toy So No Wonder Dogs Adore It!
Over the years, I’ve come to realize that not only do different dogs have distinct preferences for different types of toys with specific features, but they also respond much better to toys like this one that are well-made, durable with strong seams that don’t open easily, and that offer multiple characteristics. Although this dinosaur looks rather fierce, it’s a very good toy for very good dogs who like this type of toy! It not only has the crinkles that some dogs love, but it also has a long squeaker inside so the dog can make squeak it in many locations on the toy, and has held up extremely well to daily, energetic play. A frequent visitor to our house, a lovely Border Collie mix of adorableness, loves this toy so much when she visits that I bought another one to send to her house so she never had to be without her cherished dinosaur. :) Watching a happy animal is the best! :) On top of all that, it’s an incredibly good value! I’ve started reading more closely about toys that I consider for our pets because it makes a difference in how they use them and how much they like them. Since the whole goal is to keep our animal friends busy and happy, that makes all the difference to me. :) I hope your dog loves it, too! :)

Evisceration was nearly instantaneous but he’s hanging on!
Despite my Sunshine eviscerating this prehistoric fellow and extracting the squeaker from his innards within minutes (followed by about an hour of her laying about, lazily squeaking, it has otherwise held up fairly well! Plastic squeaker aside, it doesn’t have any other plastic parts in it and the stitching has held up (my Sunshine went for the squeaker as if it were an alien about to burst forth from the dino’s belly and acted accordingly so the fabric didn’t quite hold up as well). It’s a decent size and only had a bit of fluff in its belly for me to clean up afterward. My Sunshine is an energetic chewer so I consider it a win that this thing is still even dino-shaped and only bereft of its squeaker. My Sunshine is quite happy with this little fellow and if she’s happy, I’m happy!

Became my dog's new favorite
This instantly became my dog's go-to toy, and thankfully it's lasted longer than I anticipated. He was excited to play with it immediately, of course, but he also continued to go to it over all the other toys he has. He loves to rip and tear, so I didn't think this would last more than a day, but incredibly it's been going for weeks. Granted, he's torn out the squeaker and some of the crinkly plastic, as well as most of the stuffing, but there's still a recognizable dinosaur-shaped toy hanging around that he still likes to play with. The squeaker is also different than most dog toys, it's larger and lower-pitched, so that variation is fun. There's lots of crinkly plastic in the tail and feet, so even after my dog ripped open the tail and gotten that plastic out, there's still more noise-making stuff left in there. The size and amount of stuffing is also great, as it's given him many days of things to tear apart.
