LS7 or Coyote?

To me this would have been an easy decision before
the Coyote came out. If I lived in Australia then
the LSX's would have gotten the nod. But now after
doing a bunch of reading about this Coyote I would
seriously consider it. I saw a dyno sheet for a 32V 4.6 with a supercharger register 690 HP to
the rear wheels. That's not a typo. I also have a
good friend who has been with Ford engine development for 33yrs. He says we ain't seen nothing yet. He said the Coyote is worth way more power than people know. There is new stuff being built as I write this. So we shall see.

I have the same engine in my Cobra if you are talking about the 2003/2004 Terminator motor simply the smoothest supercharged motor I have driven I'm sure the Coyote will be the same.

You are absolutely right Hersh, 690 to the tire for the "old ModMotor" is not a big deal. They can reliably produce over 800 HP at the rear tire with extraordinary street manners and mileage in the mid 20's (they also start easily on cold mornings). They new Coyote engine is basically the old ModMotor after Ford brushed its teeth and combed its hair.

The Coyote heads flow spectacular numbers on both the intakes and the exhaust. It is worthwhile remembering that this engine produces the same power from 299/300 inches naturally aspirated as the 03/04 Terminators did off the showroom floor with an Eaton blower from 281 inches - and at essentially the same engine speed.

Put a Whipple or KB on the Coyote (or a 4.6) and it gives new meaning to the old phrase "lightning in a bottle"! BTW you don't have to do any bracketry engineering or blower drive engineering for the ModMotor. Ford has the parts ready made sitting on the shelf. A Ford Dealership in Minnesota will sell you parts at 10% over dealer cost. Here is their website => Tousley Ford

A nice side benefit of this engine choice is it is essentially the same size as a 427 SOHC but only weighs about 450 lbs dressed, so the front of the car is not only light but when you open the bonnet the eye candy is stunning. Here is a picture of a blown ModMotor

The supercharged Coyote's are just around the corner.

p.s. for our brothers in OZ (who probably already know) the 750/800 RWHP translates into 550/600 KW at the tire.

Ed,
Nice post. I made up my mind a long time ago that
I will use a Mod motor. I can see less to be done to make it even stronger for turbo or supercharging. I prefer superchargers. I have a friend that has the terminator supercharged and I cannot stop thinking
about how that thing pulls. The torque levels at 5800 RPM's which is unbelievable but I saw it and felt it. Most engines quit around 5200 RPM's
To me this is the wave of the future for Normally aspirated engines. I love the LS engines but they
are at their limit as far as I can see. Push it any more and longevity is compromised.
The mod motor has more moving parts but those parts take a load off singletary operative parts doing more than on thing.
