QC on 6 PSI
https://www.ford-trucks.com/forums/1...l#post18366762
QC Baseline before installing his turbo
https://www.ford-trucks.com/forums/1...l#post18216949
Numbers put down at the wheels baseline
275 HP
389 TQ
He did on 6 PSI
550 HP at wheels
801 Tq at wheels
You loose some due to the belt drive turning the blower, but not 200 hp worth, and not 400 lbs of torque.
As i said, you are missing a bunch of torque, and some HP... Your numbers don't compute.

389 + 20% = 466 his numbers don't add up unless he only has 10% drivetrain loss

XD, a dynojet, that might be part of the problem...
Dynojet is not a good dyno for tuning, they are good at measuring WOT pulls, but not for tuning for power throughout the power band. Mustang Dynos have the ability to apply load to the vehicle via resistance in the rollers, so you can simulate to the engine, dragging the truck up a hill, or dragging its own weight down the road, and tune the fuel, timing, etc, better for when the truck is moving under its own power, and not just spinning some free floating rollers.
I have heard from countless tuners, Mustang Dyno's hands down best for tuning, and nothing to do with accuracy, its all about the load factor and being able to get a tune dialed in properly and completely with the engine pulling real simulated weight which can expose hidden lean out conditions which would be missed by someone tuning an engine with no load against it.
Im not Calling bull**** on you, but your numbers should be, well more.... I guess its also possible you have some blowby in the engine, or a weak cylinder, or who knows what....
How many miles are on your engine?

and as I stated you don't know what your talking about a turbo is very different than a super charger and his 389 # is with a tune and at a much lower elevation than I'm at 425 - 20%=340 do the math
389 + 20% = 466 his numbers don't add up unless he only has 10% drivetrain loss
389 + 20% = 466 his numbers don't add up unless he only has 10% drivetrain loss
2. His was tuned, mine is tuned, im sure yours was tuned, or if it wasn't, well should have been.
3. His numbers were recorded on video as i recall, i watched it, cant find the link right this moment, but i was following his thread as he did it.
Not making accusations, just calling what i see, the way i see it.

ok first off ALL DYNOS load the engine that is how they work some chassis dynos are more generous than others and some more stingy that is why they are used as a tuning tool and really only good for comparing before and after changes I didn't do a baseline because I'm not all that concerned about the "number" I'm not sure what # you want to use for drive train loss but it is widely accepted 20% on a 4x4 truck so I'm not sure what to tell you but 425-20% still = 340 so assuming 20% is accurate the qc's 300k mile v10 was making 466 ftlbs at the flywheel 389+20%= 466 I find that hard to belive and I am in no way calling him a liar but that dyno must be very generous either that or Ford WAY unde rated the v10

so if we look at qcksnakes first dyno pull with no tune at 361 wheel tq and we take his suggested drive train loss of 25% that would put his engine tq at 488 still more than factory if I use 15% that puts it at 424 hmm not sure what that means

Dyno's can be screwy depending on the correction factors used I've used Mustang & Dynojet. I usually do my tuning on the street then finish off on the dyno but usually I don't pick up much if I've spent my time street / track tuning .
PSI can be funky also because if you have a bunch of mods producing better airflow you can make lower boost but more power than some else with the same sc kit.
I'm gonna end up building a single turbo setup for mine. Good god i'm super busy with woek and we are going into good fishing season so I probably won't really get started building out all the piping till january.
Intersted to see what your procharger does. Sucks HP Tuners won't work on the V10 2v cause i'm pretty fluent in that. SCT Pro Racer on order, let's see how hard it is to tune with that and how the wideband interfaces.

so whatever the number is this thing is stout it flat moves we took it to grand junction on the first tune and it made a huge improvement sadly won't get to make that trip again until race season starts again in the spring
