Torque vs. HP Revisted

Final thoughts, those believing we should have addressed this at the "power" level really didn't understand the question, this discussion has always been about the two components of power, and which one should be given priority when building/tuning a motor. Imbedded in that was my assumption (right or wrong) that the boundary conditions for the motor were kind of understood -


V8's from 289 up to say 460 max, and operating in the 3-6k range


So we agree to disagree, happens more often than not in these here parts.


I also noticed some of our prominent motor builders decided to sit this one out. Can't blame 'em, I'm sure they have been down this dirt road before, no need to choke on all that dust to a known dead end

I think you have your answer after a fashion AL427SBF. Take a look at the dyno chart back in my post #58. You don't have to rely on opinion. Those numbers that make up the graph are empirical evidence of how important big torque early in the usable rpm range and out through your 6000 rpm target really is. The HP curve is literally a straight line upwards - it don't get any better than that! Albeit the big torque starts lower than your target 3000 rpm starting point but that's all the better - in the real world.

BTW remember those are RW numbers divide by 0.85 for flywheel. TQ is absolutely your friend and as Jerry pointed out the more you can get and the sooner you can get it, the better it is.
