What about an exhaust brake?

I thought about driveline brake. . . . Maybe use compressed air to spool up a turbo?

Sounds like my Suburban. Only it has no power, ever. I thought the pump was on the way out bc its progressively had longer and longer crank times before it would start. Changed the pump to a known good used one and still a turd wagon. Starts slightly quicker though. New injectors and lift pump last year. Fuel filter has been changed 3 times (change it every 6 months) since I got the burban and replaced the fuel line from the tank to the lift pump bc of a leak. No changes in performance ever. Wondering if maybe it's just meant to be a turd lol.
Oh yeah, also bolted the wastegate shut last year bc it was getting zero boost and throwing a boost code. Thought the actuator was shot. Nope, just doesn't put out enough fuel to build boost. Wot with it bolted shut gets me about 14 psi on a cold day.
As far as turbos and towing go, I have a 35/40 hybrid on my 2000 k3500 with a 14cm housing and I wouldn't trade that for anything. By far the best turbo for towing that I have used. No need to wind the truck out with it. Builds boost early and builds it fast. Nearly as quick spooling as the stock turbo but good for a lot more airflow. I haul 10,000-15,000lbs with it quite a bit and can cruise along in overdrive with the converter locked up at 55mph with zero issues.

I pulled a combined weight of 20,500lbs the other weekend in mine and it did alright. EGT's were not excessive (1100*F max). I did spent most of it in 4th and I'd go to 5th when the wind wasn't as bad (always a Wyoming wind). Boost was around 8-10psi most of the time unless on a hill. I never even turned my WMI on. The turbo I know helps so much. An upgrade well worth it IMO. The only issue was that long ass 3rd-4th RPM drop but even then she did alright with all that weight.
This^ is why I cant wait to get my 35/40 hybrid built. After sctrailrider explained the performance of his, my mind was made up and I set out looking for that elusive hx35 14cm turbine housing. I finally found one for $225. Now I just gotta get everything else together, which is just a matter of money.
That's very impressive for the hx-35. With the 14ft tandem axle trailer I haul loaded with 6 4 wheelers and about 400lbs of gear in the bed boost was higher than that for me. Pulling into Evanston Wyoming by way of Salt Lake that wind kills my big lifted brick of a truck and I'm pushing 10-14 psi with the HX-35 I have. I know I'm dragging a lot less weight than you too so I'm sure my RPM's are a big part of the boost difference due to my rear end gearing. Looking forward to what I will see with the ATT, I pulled a small trailer on the weekend with it and at 65mph I see around 3 psi. HX-35 is a very nice upgrade though.
You're going to love it, it spools so fast and pulls, and keeps pulling all the way till redline.
SS Force, im assuming you have a regular 12cm hx35, the turbo were talking about is a hybrid hx35 14cm turbine housing, with and hx 40 compressor, with custom wheels on both hot and cold sides.
Sorry, I should have seen that in your sig. Is your compressor side an hx35 or hx40. If its an hx35, I would try a hx40 compressor, with this wheel. http://baeturbosystems.com/compress...0mminducer-5600mmexducer-3-3-1-1-1-4-2-2.aspxActually I was running the hybrid HX-35 with the 14 cm housing. I am uncertain of the wheel sizes but its off the truck so its easy to check. I know the inducer is the 7 blade.

Do you have the 60mm compressor wheel? I've tried alot of wheels and so far, that is the best wheel for my setup. Still have a 66mm to try. My drive pressure is too high, its 2:1 at 13 psi WOT but I need to drop my exhaust and see if that's part of the problem, if not, then I have a 14cm housing to go on.
7 blade IIRC is around 54mm, it is the best stock HX35 wheel though.
