Was this a real heads up race, or times posted in a magazine? Also, were these times for totally stock cars?
I saw some pretty impressive 1/4 mile times from a mercedes prepped by a company that specializes in hopping up mercedes. Stock, those S600 cars have a 5.4L v12 with twin turbos , don't they?
Do a comparison between normally aspirated cars and see what happens,
Put a supercharger on that 69 ss camaro and boost it up to 14 psi and see what happens.
