1:1 FPR? Explain please. In response to the question on cracking... I would give it about 2-3 months as it stands right now. As you know that is A LOT of weight to be hanging off a stock header. Hopefully today I will be able to rig/weld some sort of support for the turbo & manifold. I also plan to heat wrap the manifold to lessen the risk and keep temps down as bulletdsm said. I was running 110oct just to be on the safe side for the first time I floored it. The AC would probably work with this setup. I took mine out because it was not being used any how. The radiator fan had to be trimmed a little bit in order to avoid hitting the wastegate on the turbo. I'll try and get some more pictures up once I get out of class. Nothing like school at 7am.
