Coming from a turbo charged car I can say that it was always difficult to maintain full boost pressure at high rpms with a smaller turbo, because it could not flow enough air. I am not sure the size of the rotrex so you'd have to see on a gauge or learn from one of the testers 
The blower should make it's full 5psi at top rpm, as it seems to be 'fit' perfectly for a L15a, plus remember that this same blower except with a smaller pulley will be used for the 10psi kit.
The problem with turbos being too small (1.8T), is that it will over spin too fast to try to make more boost, hence a 1.8T motor that is chipped can make 18psi up to about 4500rpm, then it start to drop and around red-line it only makes 12psi. This is caused by many reasons one being the housing is too small, and the air that is coming out is getting very hot, and useless.
The charged system does have a flat torque curve, because the supercharger acts like a multiplier. The base fit map also has a reasonable flat torque curve, just much lower. With proper management, you can control how much torque you want (to a certain amount) from ignition timing etc.
It seems to me like a lot of people are worried about the lower gain in torque. Coming from a 1.8T I can tell you torque is fun, but costs you internal parts and tranny's. One thing I love about Honda's design is that they are lower torque high HP motors. Once you get the car moving past 4000rpm all you do is keep it in the sweet spot, and you'll gain ~50whp, with out having to go through as many trannies as I have on my old car. When on the 'track' everyone always shifts near the limiter, this is because this is where the power is. Torque is only good to get you moving, towing and low rpm passing, apart from these three things it only causes head aches.

according to the commentary and the dyno in siphon, there is incredible amounts of torque when compared to stock on the KWSC. i don't think we will have this issue.

no it wont. this has been covered many times. there is a law somewhere that states that unless the mod (in this case the supercharger) directly causes a problem, it can't legally void your warranty.
not neccessarily true. and if your intake or headers WERE the cause of some future problem and they can direclty link it, you would have a voided warranty.
anyone who comes to get a motor warrantied due to damage,we look into the computer or "black box" that tells u everything the motr has been through. so they can tell the power, afr's, rpms, pretty much anything. so im not so sure just taking it all off will get u by...ive bever actually witnessed a case such as this tho. and FI that isnt a dealer installed/product will void ur POWERTRAIN warranty due to the increased stress.
given that the motor is basically "tricked" into generating more power with the 5# kit, i'm not sure how easy it would be to spot. i know vw's actually know how much torque the dsg transmission is handling and will cut fuel if it exceeds ~260 ft-lb, but i doubt our little hondas have anything like that. (of course the 10# kit is a different world with electronics change.) rpms don't tell anything. af ratio would still probably be in range.
