Once you want 600+hp, it's a different game then the LS motor is the option
Old saying there is no replacement for displacement
Coming from the guy with a turbo Stang
Once you exceed the 550 - 600hp barrier it all becomes expensive.
There is a 2011 GT with stock long block sporting a KB and making 631hp. As soon as I find the video I will post it.
I had no idea the stock rods would hold that much HP,.. but apparently this motor is doing just fine. Thats up there with the LSx engines if you ask me. Even the LSx engines in stock form reach their limits after 600hp. Most suffer spun bearings, which is a testament in itself.
I am curious to see how far they take the stock coyote long block before it starts chucking parts.
So far I am very impressed with this motor. For how small it is,.. its making HP and torq in NA form that motors with 50 - 100ci more are struggling to make.
The only down side to the coyote is its initial cost. But given time,.. it will come down. These cars are flying off the dealer lots as fast as they come in. Wont be too long and the prices for a good low mileage used motor will be where the working man can afford one. Hopefully they come out with a system where you can carb these engines with a stand alone ignition system that also keeps the variable valve timing intact. I read an article where a Coyote motor was done up with out the variable valve timing and it only made 310hp at the wheels. So thats what it would be like as a carb'd version with standard cams locked in. I doubt it would exceed much more than 330 - 350hp with ported heads and aggressive cams.
Back when the Terminators were first hitting the streets I was reading about Ford development of the Coyote engines and they were working on an engine that didnt use cams at all. Strictly solenoid actuators that allowed limitless cam timing profiles to be used. At the time they were experiencing reliability issues. Given time I have no doubt this technology will eventually become standard affair on GM, Ford and Chrysler performance engines. The way they explained it that you got the best of both worlds with this technology. Extreme fuel efficiency when you needed it and max hp when you wanted it. Go from a purring gas efficient kitten to an idle that sounds like a machine gun at the flip of a button.
