They're going to be awesome for sure.

Funny how Sutton had me change to a harder rotor and a softer pad.... and wow did that ever make a huge difference!

Ron had something pretty close, those Brembo GT brakes, but my accent colors are yellowish to goldish in hue like the nickel on the wheels, or the titanium anodizing color on the rotor hats, and Ron's brakes were powder coated bright red, which would have totally clashed and I just couldn't have that. This isn't a race car, so everything has to be cool, haha

Good stuff Matt. I can't wait to see this thing running and driving!

Matt, what are you doing for headers? Looks like I'm going Boss as well and have been doing research that has shown that headers I are really critical on these things due to the odd pulse patterns. Car looks incredible man.

Matt those are BAD A$$! Rode in a Evo yesterday with 500HP and some Stop Tech. That things pulled your eye out the socket when you hot the brakes., just crazy bad! Your going to love them.

Thanks! I haven't heard anything about weird pulse patterns, but then again, I haven't been researching headers on those motors. I have been thinking of doing a dry sleeve with new pistons and rods to get to 5.3L but I the hassle and expense is worth it for 30 hp.

Yeah I don't see the value in that unless you just like the 5.3 moniker- and I do lol. I've been working with Shaun at AED (one of the best Coyote tuners on the west coast) and he's helping me design some of the parts and pieces I'll need to make it happy. Evidently these engines have an odd firing order that creates a funky pulse pattern between some of the cylinders. The stock headers are a Tri-Y design to capitalize on the pulses and help scavenge. The O2 sensors have to be placed at a specific angle, on a specific plane in the header to allow for optimum tuning. It's been an education to say the least. I'm going to be running the CJ intake as well, but with a mono blade throttle body which according to Shaun is the cat's ass. I guess we'll see. He's talking 500RW with a good intake, the right headers, CJ goodies, and his tune. In our light cars- that's mucho fun time.

Hmm, now that you mention it, I remember reading through the Coyote wiring harness instructions about O2 sensor placement, it told you where to place it, and in the case of long tubes, which primaries to place them in.

500rwhp is an impressive number for a Coyote. I'm shooting for about 460 at the wheels. I plan on using the stock Shelby throttle body because it favors better low rpm air velocity. I'd like to get as much bottom end grunt as possible because these motors are a dog down low.

Sounds like 500 would take cams which doesn't make much sense on a Boss. The gains aren't worth it according to AED.

Ford Racing exhaust cams seem to be fairly popular on the Boss motors, and they do keep the variable valve timing. I talked to Stacy at DSE about the Aluminator XS (which is essentially a Boss 302 engine with 11.5:1 compression, exhaust cams and the Cobra Jet manifold) that they swapped into her FR500S and she said it had much better mid range power than the Roush Yates Boss 302 engine in the '66 Test Car, which has custom ground cams.
