Dude, I dig your drive for hp/tq and trying to stand out from the crowd. If I were to sink money into a turbo project which I have (1971 Dodge Dart) the numbers you posted above aren't anything to chase with a turbocharged vehicle. I had a F150 3.5ltr ecoboost that with an aftermarket tune did that and then some.
What I'm saying is, that canyon isn't a hot rod.
Your going to continually find the weakest parts in it as the 520tq plays havoc with clutches, drive line components and last but not least your motor if the tune isn't good.
I think you have the funds and connections to make something really sweet like a AWD pro touring twin turbo square body from latest 70's early 80's.
Guess what I'm trying to say is expand your vision and do something great.

Hell if your bored here is a photo dump of a pro touring 70 Dodge Dart build I was working on. As far as I am aware it's the only Dart with a Cuda hood. It was at least the first anyway.
I hear you. I just like to do things a little different then most would do with a 2.8 size motor. Its all in fun. :)

Is this a Twin Turbo setup or a Compound Turbo Setup.
Its a Compound twin turbo set up. Below is the Turbo Companies description.
"Compound twins, which is different from parallel twins. Twins=2 turbos in this case. I should have clarified. In the diesel world, compound twins are popular due to the responsiveness needed in the lower RPM range where these motors perform best, ideal for towing and/or more upper RPM performance without losing drive-ability. The smaller(stock) turbo pull starts the atmospheric(larger) turbo, once the atmospheric turbo lights, the smaller turbo then becomes the restriction and we have pressure in the charge pipe between the turbos. Typically, overall boost pressure is doubled without raising drive pressure(exhaust back pressure), this is where we gain power and lower EGT's. We also see longer engine life due to the lower EGT's and better mileage while under load(ie. towing)".

I have always wondered about those compound setups. As you build pressure between the two turbos, that is creating a lot of heat, then you turn around and compress it again to make the charge even hotter. I have not been able to convince myself that this is a good option, at least for a gas engine, maybe its different with diesels. I understand the concept of good response and power, but the intake temp has had me scratching my head for a while now.

Seems to have great results on EGT heat on this set up.
They also tested the twin set up Towing 10K trailer to test the durability of the motor with the extra HP/Torque. This is what the manufacture said after they tested it.

We've got it running with twins! It pulls in the upper RPM's now and that is where it lacked before. Where EGT's were 1800* on a mild tune WOT, they're now down to 1175*. We're just on a mild EFI live tune currently. The truck runs extremely smooth and quiet compared to the setup with the stock turbo and exhaust. I'm sure we can dial in in a bit more with tuning".

Yes I realized you said exhaust gas temp the first time, but that was not what i was referring to.

Ya i missed that. I dont even know if they tested the intake temp or if they care since it wont do any damage. Obviously cooler is better for performance/ fuel efficiency. EGT is always the main concern when making more power in the diesel. I will be injecting Hydrogen into the air system and really wont know how that will react until we see the dyno results.

charge temp should be a major concern when looking for power the cooler the air the more dense, the EGT temp is generally watched because of the turbo housings being aluminum or some alloy and having a lower melting point.

well that is my 3rd grade education understanding.

Whichever having a compound setup on anything is pretty cool, this last weekend I saw an X3 with a compound setup made by IBEXX.
Sounded pretty cool and was fast as heck.

I agree cooler is better. I think gas motors get effected more then the diesels by design, but i dont know how much that is.
