Reply to "Wide and Flat Torque Curve"

The owner of the motor in question has commented that after some development work and more dyno time his motor ultimately made 549 foot pounds torque and 627 horsepower at 6700 rpm. The torque was 500 foot pounds or more between 3500 rpm and 6500 rpm. The owner also commented a TFC manifold (single plane) found 10 extra foot pounds through the mid-range, but did not make 1 more horsepower on top.

Scott mentioned the motor ran on 98 octane Australian gasoline, which would be equivalent to 93 octane in the US and Canada. Scott also commented it used one of his dual plane manifolds, modified, nothing fancy just lots of R&D to get it right.

I know everyone is into the big numbers, chest thumping and bragging rights. That's cool. The owner is happy with the motor, and Scott is rightfully proud. Those of you who know me understand that's just not where my head is at any longer. If peak horsepower were only 400 bhp I'd still be as amazed at the width and flatness of the torque curve.

If somebody shares the final dyno curve with me I'll post it up for you guys.
