Serious Annoyance...

That Prelude still handles pretty well, probably better than my 69 Corvette ;-) Car engines today are designed to rev higher than in the old days and the torque/horsepower ratings can be deceiving because they are developed at RPM's that you don't get near in normal driving. It's interesting to look at their horsepower/torque curves and compare them to the old big blocks of the 60's. A big old 454, 440 or the famous 426 Hemi developed gobs of torque at 3000 RPM or so. The new engines can develop decent torque but at much higher RPM. This V-tech doesn't really step out until you hit 5k RPM and the valve timing changes. Then it feels like the secondaries opening on an old Quadrajet. I assume the gas mileage starts dropping pretty fast too. If you drive it up in that power band it is a pretty peppy little car, for what it is (2 liter) but I get pretty good mileage if I drive a tad more conservatively. I really don't drive enough to notice the difference tho. |

I really don't drive enough to notice the difference tho. When Chrysler introduced the current "Hemi" that they use in their cars and trucks I was really kinda disappointed. I bought a 2004 Durango with the Hemi thinking it would have some "ummph" to it. It was ok but again, it's rated horsepower and torque was developed at some ridiculous RPM (around 6K, IIRC) that you would never do in normal driving. Normal acceleration with RPM up to about 3500 didn't feel all that thrilling. Certainly not the same as tromping on the gas in the '67 GTO I had with a four speed. Threw your head back. My 67 Chevelle was like that but it was bought that way. It had a 456 rear and I could chirp the tires in 4th gear. |
