RE: Power Curves and Overdrive
By allan - 10/22/2003 11:25:14 PM; IP 24.171.19.93
I can agree with that to a certain extent. However, I use the tbird as a cruiser and don't expect it to be a high performance car. Its got a nice feel to it with the acceleration it has but I realize its over 4000 pounds and just has enough power to be comfortable on the road. At 65 or 70 where it gets a lot of use, I can feel the engine RPM is rather high in high gear (though it doesn't have a tach). Compared to modern cars that shift into a higher gear and cruise at about 2000 RPM, the tbird is using itself up at a higher RPM to no advantage. Since I intend to keep the car as long as I can, I'd like to do what I can to improve its life. Overdrive seems like a good idea in theory, but since the car was not designed with that originally, I'm trying to figure out if its worth the investment or just going to be an expensive folly. Since I don't know what the torque curve looks like, its hard to predict the outcome. My theory is that if the 300 HP is rated at say 5500 RPM, then it may not be getting up into the power curve until over 2000 RPM. To me that means the engine will be operating inefficiently at that low of an RPM with the overdrive.
This thread, so far...
