Don't have confirmation, however... Waiting on a response and trying to contact the owner.
This graph is alledgedly an 11 PSI SCREW blower on a Lightning. No idea on what other mods are done, but you can bet it is completely built.
This is another graph confirming the limitations of the stock Lightning or Allen intercoolers. I say this because the SCREW blower is MUCH more adiabatically efficient than the Eaton at boost levels above 12-15 PSI. I would expect a less dramatic drop in HP on the top end from the SCREW, but I suspect HIGH charge temps on the top.
A good comparison, just for demonstrating the powerband, not to compare numbers... Notice the high torque curve but also how many RPM are in that high powerband to redline (In this case, shift point is 5600, and the truck launches around 2500 RPM).
(Corrected 700/700).
