Anybody know what the max stock rpm is for the stock 5.4L 3V in a 04 F-150?

 

I believe Mike Troyer said that the weak link in the F150 is the torque converter which is supposed to be rated @ 5500 rpm's

 

I believe the stock tune has the rev limit at 5200 RPM.

 

I start losing my power curve @ around 5300rpms. I can post my dyno sheet if needed.

 

Thanks for the replies. I lose alittle power at around 5200 rpm and at 5400 rpm the security light on the dash comes on and I lose all power until the revs fall below 5200 rpm again. I am guessing based on the above replies that 5200 would be a safe shift setpoint.

 

Mine shifts at 5,000 rpm, wish it had a little better peaking power but ohwell.

 

............hmmmmmmmmm....

so that's why there is not redline on the tach.

i learn somethin every day from this site.

thanks - oaw
