Just wonderding how much RPM is to much for these engines. I run Vivians Looney tune, at WOT it shifts at 4150, is that to much, or is that fine?
My 7.3 slams the limiter at 3500 and LOVES it. :thumb: I like float shifting it at 3500. :woot::icon_ford:Good grief! And here I've been nervous about pushing mine to 3000!!! I feel a little better now! I'm used to the 7.3 and 5.9s... they don't do high RPMs! Apparently the 6.0 does! I keep learning on here... thanks for the question!
you are right you are past the peak HP and WAY past the peak torque but the higher you rev means that when you shift the RPMs fall back closer to the peak HP making you faster.IMO RPMS over 4k seem like unnecessary risk of damage to the motor since you are past the power peak and way past the torque peak so I dont see the need to run the motor that fast.
