Not to rain on your parade but what is he going to do about the TB?
The biggest one out right now is the dual 62mm from BBK. They are working on their bigger V10 model but don't have it dialed in yet.
Jim Bell has been working on my custom dual 72mm and manifold for over a month now and still haven't gotten it down.
I don't want to be the bearer of bad news but no way you're frined is going to break 800 rwhp without a remedy to the current TB problem.
The smallest pulley you can run is a 2.5" and that is only going to make about 16-18 psi. The way we get more psi is by playing with the crank pulley's and then we can get 22-23 psi but the TB can't handle it.
My car falls flat at 6K rpm and I have to shift at 5800 rpm. I cannot run over 16 psi on a 2 3/4" pulley. This is because of the TB. The car needs more air period.
The good news is once we figure it out on my car, then it will be out for everyone. But for now, don't expect more than 700 rwhp cause you won't get it untl we get a TB solution done.
BUT - HP isn't everything... I make 501 rwhp and run 10.60's on a DD...
The day I make 680 rwhp is the day I make a 9 sec pass. (it's coming soon...)
The reason the GT500 makes over 800 witht he 2.8 kit is because of the dual 72mm TB. KB has been trying to make a manifold to adapt to the GT but it is harder than you think it is and over a month has gone by while they've ben testing it and it still isn't dialed in. I'm on a short list for this TB and wating patiently.

you bring up a good point. however; we're addressing this issue...............they use some kind of monster single-blade oval throttle body, i think accufab, custom fabbed for this application. ill get you more info on it if you want, when i find out.
haha donnie......that'll be a good race.............this kid is terrified to push his car haha.

I have no idea what im talking about; but i do remeber reading something like this in fffm mag when they did the 800+ rwhp KB GT500; they had to change the tb or something like that to push the psi past 20.

RE: friend is officially building up his GT-800+RWHP
That all sounds killer and I can't wai to see it.
I'd beware of the Stailness Works exhuast you mention though. All the good guys over there have quit recently and the entire compnay is in chaos. I buy systems from them for the cars we work on and lately it has been a complete nightmare of mistakes, wrong shipping, crap workmanship, etc. Be real careful with them until they get things back in order there in OH.
