Quick question, wheres the powerband on a stock 91 4.0

I can not really tell where it is.

Thank you.

2500 -3000-ish RPMs I believe.

 

[91sport_tn]

thanks. that seems to be consistent with my observations,

I'd agree.. good power is somewhere above 2000, but less thatn 2500 up to 3000.. at 3000 the power drops off...

The 4.0 makes a peak of 225 Ft/lbs at 2400 RPMs, and 160-170HP (depending on which source you believe) at 4600 RPMs. The 4.0 actually makes 200 Ft/lbs at 1000 RPMs and doesn't fall below 200 Ft/lbs till 4K.

Yea these things do have a sweet torque band...

 

[Fordmandan87]

along that topic would 65mph at 1750rpm be a bad thing

thats about where mine is @ 2k im going about 67-70 mph but hard to guage that data from a speedo with rabbit-idas.

I wish the 4.0 was a little more eager to rev, but it does make decent power.

Mine has 288k on it and it still has enough power to get the job done.
