New car mfrs. and used car sellers should provide this ratio directly to inform buyers. It seems so basic…Any insight why they don’t?
The ratio can be manipulated somewhat and should generally just be a guide, and the assumed conditions of its calculation stated, but it’s still meaningful when comparing - 1 car to another. What do you think and why? |

OK, I'll play.
Just weighed in at 2423 lbs wet, without me in it. Factory rated at 430 hp. With ITBs, it dyno'd 518hp/464 torque at the crank. I'll rate it at "too many/lb" (IMG:style_emoticons/default/aktion035.gif) Attached thumbnail(s)
