ATS Aurora 5000 (71/83) .90 AR
Here is ATS’s marketing advertisement for the Aurora 5000:
The Aurora 5000 is a high performance turbo charger that is great for added horsepower and torque. The 72mm inducer on the turbo is a significant jump in performance over the stock charger. This turbo has the capability to reach over 850hp with supporting fuel modifications and aggressive tuning. The increased air volume will utilize all fuel injected into the cylinder creating a more complete and efficient combustion event. This will result in lower EGTs, high horsepower capabilities, and a more efficient/powerful torque curve.
The advantage of the Aurora 5000:
Ability to support 850hp
More efficient and powerful torque curve
Designed for street/drag strip/sled pulling performance
Lower EGTs under higher horsepower applications
Reduces turbo "bark" due to ported compressor housing design
Great performance gains
Perfect for high HP applications
Great for racing and competition
Aurora 5000 Turbocharger System will include all necessary hardware for a smooth installation. This turbo is not the ideal choice for towing heavy loads, however can be used in most cases for daily driving and moderate towing. The turbo comes complete with all hardware, 4-inch down pipe, 5 to 4-inch intake tube and 3.5-inch compressor discharge pipe, Boost levels of 70 PSI are possible with this turbo. NOTE: Recommended use of head studs with this turbo kit
Here's some tech info about the Aurora 5000:
Aurora 5000 (approx. 95 lbs./per min)
• Capable of 330hp over stock turbocharger
• Competition performance while maintaining the ability to still be relatively streetable
• Lower EGT’s
• Vast increase in horsepower and torque
• Billet Compressor wheel: 71mm inducer (2.8 in) - 7 Blade
• Billet Compressor wheel: 100mm exducer - 14 Blade
• Turbine wheel: 83mm inducer - 12 Blade
• Turbine wheel: 74mm exducer - 12 Blade
• A/R housings: .76, .90, 1.0, or 1.10
• T3 or T4 exhaust flange
Here's some stats from my recent towing experience from CO to MD then from MD to GA. I was towing a 6,000 trailer with 1,000 lbs in the bed under the tonneau cover. I just made notes randomly as I was driving on my iPhone. I have 37” tires and 3.73 gears running MM with HD ATT .29 and OD trans tuning: Through the hills of Colorado: 15-18 psi of Boost. Rail Pressure 20.5 - 21 ksi. Trans Temp 168. EGTs 890-940. 1900 RPM at 78 MPH. 12.2 MPG on the EVIC. Flat land across Kansas: 12 psi of Boost. Rail Pressure 20.5 ksi. Trans Temp 170. EGTs 850º. 2000 RPM at 81 MPH. 12.0 MPG on the EVIC. Through Illinois: 8 psi of Boost. Rail Pressure 15-16 ksi. Trans Temp 165º. EGT 890º - 950º. 1600 RPM at 78 MPH. 13.4 MPG on the EVIC. Hand Calculated MPG was 13.7 - 14.4 consistently throughout the whole 2,300 mile trip.
My overall review and feedback:
I love the ATS Aurora 5000. It’s a solid, well-built turbo that appears to be and feels bulletproof. It sounds great, feels great and spools awesome!!! The turbo is a little laggy on the bottom end with stock fuel but not bad at all. The mid-range and top-end are amazing!!! This turbo really woke my truck up. ATS doesn’t advertise the turbo for towing but my truck tows great with it. With my gearing and wheel/tire combo it does not like 6th gear at low RPMs. It will sometimes surge if you let the RPMs get too low (1100 or so) and then step on it without downshifting. I prefer not to use 6th gear anyways unless I’m on flat ground and traveling 75+ MPH (where it runs great) so no worries there. I tested the turbo with both 1.0 AR and .90 AR housings. I think the 1.0 AR may have provided the best power on the top end but the .90 AR feels the best as a daily driver so I decided to stick with it. The only downfall to a huge turbo like this is you’re producing so much boost as a result of all the air you are providing to the intercooler BUT when you abruptly lift the throttle the turbo will often bark as all that air/boost has no were to go. I plan to ad a BOV so when I lift the throttle the gate can open and let the unneeded boost escape. EGTS: This turbo really makes its money in the EGT department!!! Cruising around town or on the highway I normally see 800-950º BUT when I stomp on it the EGTs almost instantly drop to 600-700º most of the time. It’s crazy to me to see numbers this low after running so hot with other setups in the past. I have never, not even once hit my defuel of 1450º (pre-turbo in the manifold at the collector). I have two EGT probes and monitor with both the H&S Mini Maxx and the Snow Performance Module (each have their own probe). BOOST: I see lower boost numbers at low RPMs lugging around town BUT when you get on it she’s a monster. It’s much more powerful with less pressure on the accelerator and it breaks the tires free very easily when the turbo lights. I have seen boost numbers of 47-48 psi in Colorado at 6,500 ft elevation on the WILD setting running .29 tune and 56-57 psi in Georgia at 482 ft elevation on the HOT setting running .30 tune (Both times running the H&S trans tuning). All of this was on stock CP3 and stock injectors.

Here is the billet wheels in mine and then another of it in-between the 4000 and 5500 wheels...

Here are some picts from the mock up. The boost tube was modified to be clean looking single piece and will come like that in all future kits. Mine was originally installed with the modified and painted boost tube but when I went back three weeks later to get the smaller AR housing they swapped it for a nice powder-coated one.

I know a TON of people will ask and a TON have already so here is my seat of the pants comparison to my old II Silver Bullet 66. Let me start by saying that I LOVED my SB66. It was a great all around turbo and I never had a single complaint. I’m also no expert on turbos and don’t claim to be even close to one. With that being said I'm always looking for bigger and better so I jumped right on the opportunity to go to a larger 71mm charger. I know comparing a 66 to a 71 is like apples and oranges but so many people ask me on a daily business I figured I's share my opinion. The SB66 spools just like a stock turbo on the bottom-end and has a great mid-range and decent top-end. It lights early and spools fast. The Aurora 5000 spools slower than stock on the bottom-end but has a great mid-range and amazing top-end!!! I got very similar boost numbers at low RPMs with both and they both light at similar times. The main difference is the amount of air they flow and the amount of boost they produce. I only ever hit 46-47 psi with my SB66. I can hit 49-50 psi with the Aurora 5000 easily on stock fuel plus the truck has less restriction now (Boost is just a measurement of restriction) with the stock grid heater deleted and relocated. I know the turbo can exceed 50 psi but I’m still playing with timing and custom tunes ; ). BTW when I hit 50 psi the boost tube silicone boot exploded and I just replaced it so we shall see how it goes from there…

Hopefully there is some half way decent info in here for those of you who have asked me for it... and YES I know I need to make so videos. A birdie whispered in my ear that the wifey has a GoPro HD Hero 2 Motorsport Edition and all the goodies for my birthday on the 8th ; ). I'll made a TON of videos the following weekend and post them on my Youtube channel http://www.youtube.com/user/ShanepxII/videos. There is currently some SB66 videos and some walk arounds after the Aurora 5000 but nothing crazy yet...
As requested here are some more pictures and a video after the install...
