Torque/HP curves
Ok, here's the deal. I drive everything using the tachometer. Yep, even my
2.5L TJ. I determine shift points according to torque rating for the
engine.
The problem is, I'd like to get my hands on a Torque vs RPM curve, - or
tables. Usually, the manufacturer published a composite graph, showing
Engine Torque and Horsepower vs Engine RPM.
Not Jeep. Jeep doesn't even know what I'm talking about.
Anyone out there have such info?
Thanks

Jeepers are not fond of Dyno's my theory is that we are sooo cheap that
Dyno's would show us how little we gain modding our I6's (and especially
the 4 bangers) that it would ruin our favorite pass time.
And before you think I'm purely joking look at all the claims of 40
horse power for the 4.0 head swap (into a 4.2).

Re: Torque/HP curves
I don't think you'll find anyone that will waste their time dyno
testing the Jeep's 2.5 Liter four-cylinder, which generates 125
horsepower and 150 foot-pounds of torque to chart it. But the horsepower
and torque curves will look similar to this six:
http://www.----------.com/temp/4LEngineHP-Torque.jpg The most sensible
way to shift is progressively, (like commercial truck drivers) that's
increasing the RPMs with each shift as your speed increases, like
there's no reason to max the horsepower pulling away from the stop
lights in first gear, but as you as you know on a hill your tiny engine
must be pegged right up against the governor in order for your top gear
to take over.

Re: Torque/HP curves
Bill:
Do you have a link to a similar torque curve chart for the Jeep 3.7L V-6
and/or the 3.8L V-6 used in the '07 Wrangler?
