N/A Horsepower potential?

Hey guys. I'm starting to think about selling the FRPP roots blower I have and heading for the N/A route. I have a few reasons for that, being that 1) I have always been a fan of "all motor" horsepower, 2) Blown gt motors can tend to be ticking time bombs that I can't afford to repair, and 3) I really, really want to do some kind of shaker system on my car, and it won't work with the blower setup I have. The blower is sitting in my shed, so right now the car is pretty stock and waiting to head down one of these routes. So here's what I'm thinking, and about where will this put me? I have an 04 GT with TR-3650 transmission:

Accufab 70mm TB
Roush CAI
Accufab upper intake plenum
VT stage 1 N/A cams (don't want to change valve springs)
Shorty headers (not sure which brand...)
MAC catted Prochamber (have to pass emissions, and evil cops around here actually look for cats and are hard on noisy cars)
Borla stinger catback or CDC side exhaust (I know side exhaust costs a few HP, but I love the look)
Karkraft shaker hood scoop system
Steeda underdrive pulleys
Sniper 93 octane custom tune
3.73s
FRPP aluminum driveshaft

I feel like this setup would be pretty darn reliable, and a fun street car to drive. I'd like to get close to 300 RWHP. So, what do you think a setup like this would do?

Installing the blower isn't an issue. I built a 302 for my old 87 over a week with a friend, and then did the top end again a few months later. I'm just not used to these modular motors. I have been thinking about a centri blower, but the roots appeals to me more if I go for boost. I'm almost tempted to just get a shaker kit from CDC and then fab up my own brackets once the blower is in to make it all work.

I hear ya on the costs, and I know the shaker is pretty much for looks, but I love that look... I think I could make the CDC kit work with the blower anyway. I might have to fab up a bracket, since it is supposed to mount to the alternator, and with the FRPP blower, the alt gets moved. I could make a bracket that puts a place for it to mount, still use the alternator as an anchor, and put a loop around the blower neck for support. It would take some work, but I think I could do it...

I believe the older Roush blower is the same as what Dirty_D and I have. I've seen it on Ebay, the older Roush stage 3s had this one. It is the same M112 Eaton on the Cobra of 03-04 fame, with a different intake setup mated to it. I'm sure with a good heat extracting hood, a nice tune, and methanol, this thing can be just as good as any other roots blower, and won't be the "cheap heat soaker" everyone claims it is. I personally like the shaker, so no heat extraction for me, but adding cold ram air at speed might help a little bit. It'll help alot when it puts a big smile on my face every time I see it shaking in the hood. Hell, that's why we build these cars, right? To be happy with 'em...
