So . . . it is my intention to build "big power" in my 08 in coming years. Right now, I'm on a stock 3V with a KB stage 1 and headers. I have already done the suspension and installed a T56 with RST and one-piece driveshaft . . . so I'm about ready.
Point here, I have been doing A BUNCH of research on my options. Originally, I had thought I could look to an MMR build 3V and upgrade the blower to a KB mammoth with the DOB manifold. Could then sell my low mileage 3V with the Stage 1 blower as a unit and recoup a little bit of cost.
But, I have started looking into other blowers and other engine options . . . which is when I came across DOB's article about the Coyote's limitations because of compression.
Bottom line, if you build the 3V, you can get into the big power range and only become limited by fuel and the blower's cooling capability.
With the Coyote, you run into issues with compression unless you buy an aluminator . . . which is more expensive than a 1000 HP capable MMR 3V.
I might be missing something . . . still researching. Might also consider a 5.8 swap out of a 13/14 GT500.
