Industrial Injection S475 2nd Gen Turbo Kit 03-07 Dodge 5.9L CumminsThe factory turbo found on the 03 07 Cummins is capable of supporting sub 450 horsepower levels. Above this point, it is being oversped that will result in failure, as well as the fact it simply cannot supply enough air to support horsepower levels above this point. Further, the placement of the factory turbo is not positioned in an ideal position as its centered on cylinders four and five as opposed to three and four, resulting in the front cylinders

The factory turbo found on the 03-07 Cummins is capable of supporting sub-450 horsepower levels. Above this point, it is being oversped that will result in failure, as well as the fact it simply cannot supply enough air to support horsepower levels above this point. Further, the placement of the factory turbo is not positioned in an ideal position as its centered on cylinders four and five as opposed to three and four, resulting in the front cylinders running hotter than the rear.

So, what's the fix? Easy, this turbo and installation kit from Industrial Injection to improve airflow and square the turbo on the engine!

And now, lets talk about the turbo. Industrial Injection has done a LOT of research on turbo sizing. This particular S475 on a 5.9L will work best when used in conjunction with custom tuning and a larger set of injectors for power levels above 800 rear wheel horsepower to deliver maximum street and track performance.

Turbo Options - The standard turbo kit will utilize a 1.10 A/R exhaust housing which is great for maximum boost levels and low drive pressure. However, if you're running minimal injector size (around 150), oversized tires, 3.42 or 3.73 gears, etc., you would be better suited to run a smaller A/R ratio, such as a 0.90, to actually increase drive pressure to assist in turbo spool. But if you're somewhere in the middle, say running 180 horsepower injectors, 35" tires, 3.73 gears, and daily drive the truck, you may be best suited for the 1.00 A/R housing.

Alright, its time to stop messing around with smaller, bolt-on turbo upgrades. You want big power and you need the right turbo to get you there. No, we're not talking about 500 horsepower, or even 600, you want 800 plus ponies lighting up the pavement, and this turbo kit is what you need to get you there.

Puppy loves it!
Size: 6 Inch, Color: Bone
I have a very energetic lab puppy - this chew kept her still for longer than any other toy I’ve tried (besides bully sticks and peanut butter). Highly recommend!

Good for an aggressive chewer
Size: 6 Inch, Color: Bone
My dog loves it. These last a long time. My dog is a Rottweiler/American Bulldog mix, she goes through a lot of toys. So, I try to buy her something that has no stuffing, but will keep her from getting bored. This one has lasted about 6-7 months, the leather is chewed off, but it's still the shape of a bone. I did just order another though, the one she has is a little stinky from her slobber. :-)

Not as expected
Size: 6 Inch, Color: Bone
I have been looking for these ever since we got a similar one at Sierras for our 1 1/2 yo Cane Corso. She is brutal on chew toys and the first one from the box store held up well. However, this did not hold up as well and she was done with it in less than a week. Still looking for that perfect toy.

More durable than expected.
Size: 5 Inch, Color: Raccoon
I was walking through my front room the other day when I noticed a suspicious spot on the floor. It looked like something I should not touch without gloves. As I got closer, I realized what it was. It’s the ‘guts’ from this toy. My dogs (Pit Bull and German Shorthaired Pointer) were each given one. Both are aggressive chewers with their toys. They ATE the faces off these toys and now play with the felt interior. I’m still trying to figure out how they ate through leather while the felt remained intact. Regardless, they still play with them. Now they are basically semi-fuzzy throw toys we can throw in the house because they don’t leave marks on the wall if our aim is off. Sometimes things work out the way they should. :)

Great with supervision
Size: 6 Inch, Color: Bone
My dogs LOVE these, but removing a star because these apparently are VERY delicious and they will ingest what they rip off if I don’t supervise; also removing a star for how quick they’re able to tear these up. These are like catnip for dogs, I’ll still buy them!
