Go back to the chassis dyno and make a few pulls, adding a few hundred rpm to the top of each pull......... up to the point where you encounter valve float, or reach an rpm limit you’re comfortable with.
I think you’ll reach the valve float stage well before 6500.
Whatever rpm it occurs at....... the “redline” should be a few hundred rpm lower than that point.
the torque is over 525 and slowly tapers down to more like 450 at 5500rpm but the rear wheel hp was still climbing there, hitting 362 at 5500.
Look your sheets over more carefully.
The hp is just a calculation of tq and rpm. If you have 450tq@5500 rpm...... that’s 472hp.
Conversely....... 362hp@5500 is 344ft/lbs.
HP is always higher than TQ at rpms above 5252, TQ is always higher than HP at rpms below 5252.
