Several people have expressed interest in a naturally aspirated Coyote build. The Dyno numbers have already been posted. You can see the car here Mustangs Daily - Ford Mustang news, new products, reviews and features and here 2011 Mustang GT Load Bearing Dyno Run 520 RWHP 7700RPM - YouTube 2011 Mustang GT Dyno Print Out 520 RWHP - YouTube
I wanted to share the changed characteristics of the car as a result of the build. First, it is a different car. There is not much left in the way of variable cam timing due the phase limiters. The car will remind you. For instance, if you are in third leisurly taking a corner at 1700 rpm drinking your coffee, the engine will belch, the car will stall and you will spill coffe all over your new work shirt. Of course that did not happen to me. One must now pay more attention when driving.
I cannot compare this car to anything else because there is nothing else that I have driven like it. The cams are not heard at idle but step into it at 3000 rpm and you will hear the blah,blah blah, sound followed quickly by a scream like she was getting eaten by a shark. All the way to 7700 rpm. Acceleration achieves hyperspace at about 4500 rpm. It is hard to keep off the upper rpm band, especially with this 3.73 gearing. It drives like a European Sports Car with a Muscle car sound. I don't know how many European Sports Cars have this kind of acceleration though. None that I could afford that is for sure.
The engine achieves it's torque peak at 6550 close to the former redline. The powerband is so wide . . .that this is just the most fun car I have ever driven. It does not have the neck snapping torque of the 2013 GT500, but this car is a different experience. It is essentially a souped up Boss.
The car is easy to drive around town as long as you pay attention. I went to Gt500 mufflers and they are the right note and not so loud as to attract unwanted attention. I have not gotten any times on it, but this car is very fast and mid to high 11's on street tires would not surprise me. The high redline lets me take advantage of gearing so much better than any other car I have had. I am just addicted to it now. If I could, I would push this right to 8400. The engine has been balanced and blueprinted and we are confident it could handle it.
Naturally aspiratd is more expensive but I think it is ultimately more rewarding because it really requires better driving to take advantage of the powerband.
