None, Facebook is the Devil! None, Twitter is for Twits! None, I hate it when my boss snoops the net about me

In light of Derf00's Road & Track link, I'm astonished that I'm right on the mark.

However, despite my BHP guess being spot on, there are still too many question marks left to be answered.

At what RPM does that 435BHP occur at? This reveals a single point snapshot of what torque the engine is making. All we know is 400ft-lbf is the announced max crank torque. And we don't know what RPM that 400ft-lbf occurs at
What does the entire torque curve look like? This dictates the true power characteristics of the engine and how well it will move that additional 89-90lbf curb weight.
What is the S550 Coyote redline? Is still 6800RPM? or is it now 7000RPM? Or is my guess of 7100-7250RPM correct?

I will hazard to say that the redline will either remain at 6800RPM or be bumped up to a true 7000RPM.
I am changing my initial redline guess because upon looking at the S550 Coyote intake runner design, I am guessing that the runner length remains exactly the same as the outgoing S197 Coyote intake runner lengths.

I will have to revise my torque curve guess too.

Squirrel of Death!
Do not **** off the SoD!!!!
