VIDEOS AT THE BOTTOM OF THIS POST! Check it out!
Firstly... I wasn't planning on writing this review yet because it's going on 1 in the morning and I'm tired. However
, I'm so impressed with this turbo - that I wanted to write down a few things before I forgot any major details, and partly because I'm filled with such joy and ecstasy that I feel indebted to Adrian and his creation.
This is the turbo: the 64mm (63.5mm same as Powermax) LLY DuraStroke w/ Batmowheel - with the mad scientist himself installing it personally in my truck.
The Review: (short and sweet for right now)
My first impression of this turbo was that it sounded fairly close to stock. No crazy whistle or anything like that. However, when you're in the early-to-mid range of building boost, you get this insane
whistle/sucking sound coming from your intake. It sounds amazing
and I found out from a friend (whom I just dropped off at his house no more than 30 minutes ago) that it sounds incredible from outside the cab, when it's driving off.
My first test drive of the turbo wasn't at all what I expected. This is going to sound weird... but just hear me out. The truck felt slower. I didn't feel that amazing torque/suction feeling in the seat that I was used to on the stocker and Matt's SRL+ tune. The truck just seemed to gradually accelerate and never really threw me back. I looked at EGTs and they were in the 900*~ish area and boost was about 24-28 psi range as I laid off the throttle from a "decent" run. I thought to myself, "what the hell? I thought this thing was supposed to give me more 'oomph' than that..."
That's when I looked at another gauge of mine....
The speedometer. Like I said, those numbers (EGT and PSI) were "what was left" of me giving it a quick and somewhat short 'dash' on the throttle. The speedo was coming back off of 100mph. I literally said "Holy Chit! I had no clue I was going that fast!" The turbo is so smooth
that you don't really feel the boost "thrust" you into your seat - at least not immediately after you install it. After the install and driving it around for a little bit, the truck has started to change it's strategy and learn with the new hardware. I did a few more runs with it, enough to confirm that a WOT sprint to 70mph happens VERY quickly, and results in more than a 300* drop in EGTs compared to the stock setup. (1600 vs 1300)
EGTs on the interstate back from Hunter's Performance tonight were around the mid to high 600s going about 75-80, and hovered around 7-8psi. I thought that was pretty good and about normal... then I realized that my A/C was on. "Hmmm... I wonder what would happen if I turned that off." - Hit the off switch. EGTs dropped to high 500s and PSI went to 5.
I will post much more about this turbo tomorrow (later today) - I just wanted to get a thread out there now. I owe it to Adrian and to anyone else interested in these turbos. I can't describe it. And believe me, there's plenty more info that I need to/want to share with everyone. I'll write more after a good night's sleep.

EDIT: 13 May 2012
Dyno'ed the truck yesterday, it made 473rwhp. Now, Bill at PHP says that I had two
things not going for me on the dyno/test day.
Number One: It was mid 70s and humid, when I dynoed in Feb (made 454rwhp/980lbs/tq) it was below 30* - so my numbers will automatically be 15-20* lower.
Number Two: My truck was suffering from something called "Heat Soak" - which basically means I never let my truck cool off from doing dyno run after dyno run. If I would have let my truck cool down, I could've picked up an extra 5-8rwhp.
So putting those numbers together, that gets me pretty damn close to 500rwhp in ideal conditions to dyno. How about them apples???
