TiAgX5--- I honestly don't know. I will say that I trust Jed and from what I've read, have heard nothing to indicate that anyone has convinced him to change a thing. If you're correct, I'm guessing the difference on a real-world daily driver would be hard for me to notice at the wheel and at that level of perfection, I should have replaced the crank and pistons with lightweight versions and done a full extrusion hone on the heads to maximize flows, I did not. I'm just looking for the best I can get without building the space shuttle.
J. Belknap--- Thanks. How's your X doing? Love reading the story of how you landed that rig and got it home.
Crystalworks--- who knows. Dyno, dyno, dyno. I'll know then. I have found a slight difference in a domestic hp number compared to a German hp number in comparable displacement engines. If you've seen the inside of a 4.6is exhaust manifold, you'll know that just about anything should be better.
If anyone thinks that bmw didn't half-ass the exhaust manifold on the 4.6is, check this garbage out. Anything would be better.
