HP500 Performance Curves
I don't know if Mercury ever published the horsepower and torque curves for this engine. Anyone have them or had theirs dyno'ed and have all the numbers?

Mike,
Here's a thread from another site that has a post in it with the dynor results from a stock carbed 500HP. If you don't have a registration to view the file, let me know and I will email it to you. Basically, the motor pulled a peak of 530 HP at 5400, and peak torque was 546 at 4300 RPM. It has a nice broad torque curve, 540+ ft/lb from 3500 all the way to 4800 lb.

I may have to go hunting for a good used 500HP carb cam.
