how many of you have your rwtq and rwhp cross at 5200rpm?

[LANDY]

As the tittle says. Please post your dyno sheets if possible. :beer:

Nice. Can anyone explain why that's preferable.?

[TooManyFords]

Technically, they *all* should.

They all do.

The reason some dyno sheets look like they don't is that the scales for hp and tq are not set to be equal. Look at the numbers on the left and right sides of the graph, if they are the same the traces will always cross at 5200.

Very interesting. Thanks guys.

My Marauder has not been on the dyno is years so I don't know where the lines cross.

But....

My car crosses the line at 9.67. Do all Marauders do that?

[Bluerauder]

Actually, they should all cross at 5,252 RPM. Its a math thing.

My car crosses the line at 9.67 @ 140mph. Do all Marauders do that?
fixed it for ya.

Yep, By definition the horsepower should always equal the torque at 5252 rpm:

For a given torque and speed, the power may be calculated.
The standard equation relating torque in foot-pounds, rotational speed in RPM and horsepower is:


HP = (TRQ x rpm) / 5252


The constant 5252 comes from (33,000 ft·lbf/min)/(2π rad./rev.).

10 q!
