427W FI or Coyote or Supercharged Coyote

[bobcowan]

A good 427W stroker a blown 5.0 will give you about the same HP and torque numbers. But the 427 tends to be more linear. The blower tends to "come on", so to speak, at a certain point. A bit more dramatic.

the NA Coyote makes less power than the other two, by quite a lot. But it's extremely predictable and easy to drive.

Whichever motor you choose, install EFI right in the beginning. I'll never mess with a carb gain.

Bobcowan's viewpoint is in sync with mine.
A 427W FI crate engine will produce a predictable push to 575HP at 6500 which is plenty for these cars.
In addition, there's less complexity to contend with when it's time to wrench.

You're the exact person I would like an opinion from, a person who has a supercharged Coyote. How is it to drive?

It is a blast! I love to drive this car. It is smooth and responsive, with good power everywhere. It does "come on" when the boost really comes up, the car takes off, and presses you back in to the seat. The first couple of times I drove it, it was kind of scary.

BUT... you do have to be careful. You can't just stomp on the gas. If you do that it will just boil the tires. You have to roll into the throttle.

You also have to be careful about passing. Step on the gas move over, pass, move back. Look down, and you're in the triple digits. It's that fast and smooth.

I also have a 6 speed auto trans. It is so smooth, you don't even notice the up shifts.

I agree with Bob, a supercharged coyote powered Cobra is the definition of a "blast". As I mentioned in my reply PM, that engine/power adder combo is scalable through use of different sized pulleys and the tune. You don't need to go straight to 800rwhp right from the start. As you get used to the power, you can increase boost and adjust the tune to get to whatever power level you feel most comfortable with.

Happy to answer any other questions you may have.

No matter what direction you go, get what you want and have a blast through the process.
