I figured you guys get this question a lot about turbos on a vp44 truck. But I’m really in a bind and forums just aren’t helping.
I’ll start with the truck.
01 cummins. 7x11 dap injectors. Promaxx head with heavy porting and #103 springs. 30% over so vp44. T4 manifold set up. Everything studded. Electronics I have the iQuad with v2 tuning.
Tranny is a full built 47re with a 300 drop triple disk converter. Ratchet shifter with standard valve body.
3:54 gearing.
I’m in the hunt for a new turbo. But I’m am stuck. I been looking at the s363/68 and 73. With a .91 housing. Or .80 gated.
My issue is I’m not so much worried about power as I am worried about egt. I have a hx40 with a turbine measuring 76x64 exducer. I have made a very small tune and I can still get 1500 egts in 7sec.
I am worried a s363 with the 68 exducer will not flow enough. And wondering if the 73 will?
I’m jumping to a whole new subject. But I been looking at a s464. And everyone talks bad on them on the vp44. But I can turn 4000 rpm. And was wondering if it could be a option?
I want to get a turbo that will get me a controlled 1200-1500 egts on my larger tune. And if I can get this. I will add water meth to help more.
The truck is a daily and pulls maybe 5 times in a yr. I’m mainly pulling loaders. Weighing 7-12k.
I know my power and boost won’t be there till 2000rpm with a s464. But I’m still worried a s363 or S364.5 with the 68 or 73 won’t support my egt issue. I would like 600hp one day but I’m not saying these turbos are gonna put me there with my mods. I just want them to be able to support that power and support the egts with it when that day comes.
