Attention: TDR Forum Junkies 
All I can say is WOW, this is one sweet turbo. Last Tuesday I went to Canada and had Piers install his Hybrid turbo. After a week of driving and playing around I can say I am very pleased with the way it performs. Being that I went from the HY to the Hybrid I will say that I didn't know what to expect other than I will gain some lag. Well that did happen but it is not near as much as I was expecting. From a dead stop it reaches full boost at about 1750 rpms which on 5x5 for my truck is 57 pounds of boost. While on the freeway I smashed it and the highest EGT's got were 1300. That was at over 110 mph. 
Needless to say the HY would bury 1600 in about 400 yards. EGT's are up when cruising down the freeway but by the time it hits around 900 the boost is coming on. That is to be expected since I am cruising at lower boost pressures. With the HY I was cruising at 13 psi where the HX-55 is at 5 psi. As far as smoke is concerned, it solely depends on how much throttle I use. I hardly smoke when going with the flow. If I floor it..... can you say black out. 
The Hybrid uses a Schwitzer exhaust housing that is equivalent to about 15 cm2. It is machined to mate up to the Holset components and also machined to clamp to a HX-40 down-pipe. Since I don't know alot about the workings of turbos, I will leave the technical aspects for Piers and his crew to answer. Lag should be slightly more than a HX-40/16 though I have yet to compare.
As for results... ... 486 HP and 944 ft/lbs with DD3's and Drag UFM.
Can't wait for larger injectors. 
Oo. I will post some pictures soon of the installed turbo and Dyno sheet.
