Says who? Have you ever heard of a TGP half-shaft even bending from high torque let alone breaking? When I had the half-shafts rebuilt for the 5-speed swap the driveline shop that did them said "they looked strong as hell" and he was going to try them on his 550 HP Karman Ghia drag car. He told me the CV knuckles could use a higher tensile strength needle bearing in the rollers...but the axles themselves would handle more than a 3.1 Turbo motor could throw at them... 8)

mclaren18psi(I think that's his name) posted something about "blowing out" a half-shaft when running ET streets at the drag strip, maybe he can give us more details.....

I personnally dont think that equal length headers in a turbo app is that big of a deal. In fact I dont really see many turbo headers that are equal length. The main reason being that the exhaust system before the turbo is under a lot of pressure. Especially during spool up time before that turbo gets going. I've heard (on SyTy's) that the pressure in the exhaust can be as much as 40psi. To me under that much pressure the pulses really wouldnt matter anymore. Id think that headers would hurt performance because they move too much air and therefore kill you spool up time. Im not an expert or anything but thats just the way I think of it. I very well could be wrong.

More air moved in the right way is EXCELLENT for spool. The more air you move, the faster and harder you push the turbo, therefore, the faster it will spin up. As far as headers, equal lenght headers make a "slight" improvment over manifolds, but unless you are a serious racer looking for every little bit of power(in which case you probably arent driving a TGP), they are a waste of a LOT of money. I'd stick to ported manifolds.
