HP/TQ curves
[updated:LAST EDITED ON 19-Dec-02 AT 07:10 PM (EST)]As promised, here is the horsepower and torque data from the graphs found in the 1989 and 1990 F-Series brochures:
300 I6
hp: 150@3400
tq: 260@2000
RPM tq. hp.
1000: 230 40
1500: 250 70
2000: 260 100
2500: 260 120
3000: 250 145
3500: 235 150
Just for comparison:
302 V8
hp: 185@3800
tq: 270@2400
RPM tq. hp.
1000: 230 50
1500: 250 70
2000: 265 105
2500: 270 150
3000: 265 155
3500: 255 170
4000: 245 185
351 V8
hp: 210@3800
tq: 315@2800
RPM tq. hp.
1000: 260 55
1500: 280 85
2000: 300 120
2500: 305 145
3000: 310 180
3500: 300 200
3800: 290 210
These graphs aren't very good, making them probably not 100% accurate. The 300 only went to 3500 and the 351 to 3800 for some reason. And as you can see, the torque curve of the 302 is nearly exactly the same as the 300. Anyone who's driven both knows this isn't true. Could it be a little bias from Ford not wanting their optional V8 to be outperformed by the base 6 in torque
?

:-) :-) :-) Wow. Great information. Thanks a bunch. The accuracy is probably close enough, given that torque figures will vary between engines and weather conditions anyway.
