BTS, JW, and RacerX put mor than 10hrs of just machining time in to there builds to be able to add more clutches and increase fluid pressure. And a lot of custom made parts.
This is my .02. I'd hate to see you waste a couple grand and be back in the same spot. It's your money spend how you please.
BTW when I was one the phone with Brian at BTS for more than a hour and a half he told me to go for if I had a good builder and if I wasn't going to break the 450hp mark. And never once tried to sell me his trans or talk me out of building one.

Guy is giving me one year unlimited miles........here is the most power my truck will ever see is stage twos and d66 or whatever cleans stage twos the best I'm wanting a tranny that will hold that and not have to worry about it but I refuse to pay 5 grand for a tranny and that not even be installed I'll have to go threw the hassle of pulling and installing and the shipping will be outrages I live nowhere near bts or jw so driving there isn't an option in all reality stage twos I might see 450 at very best

Darin has to be right around 400 with a guy that builds his race car trans. He used red eagle clutches, Racer X TC and VB. I believe Darin has even said its a good build, but probably one that can't get abused to much.
The bottom line is that if you want a reliable 500hp trans, there are only a few options and the cost is not cheap.
Todd's right on mine, I have a good build, but I could wreck it if I tried. I agree if you want to hold 500hp, you need to spend 5000. I just couldn't swing the cash for one so I went this way. I do work it hard, but only a few thousand miles a year, so I hope it lasts me a while. I do no hotrodding with it, just drive it like a work truck.

I'm amazed a lot of people never think of doing that. I've done that with an automatic tranny just to take the stress off the tranny while backing. And when I tell people, that think I'm crazy until I explain to them that I don't lock in the hubs, I just use the gear reduction in the low side of the transfer case. And, I wouldn't be opposed to do it with auto hubs if there's very little turning involved, and on gravel.
