When I had my Superformance 427 Cobra replica, with a stout near 500 hp engine, sometimes I would be alongside some turbo car, and since they took a second to spool up, and I had instant acceleration, I could jump out say from 70 to 90, and about the time their turbo would spool, I could slow down and let them go by. The advantage of a non-turbo power plant was instant acceleration.
Once had a few roll-ons with a Vette, maybe 70 to 90 or so on an interstate, and we waved to one another as he took an exit. Just then, a High Way patrol came up fast behind, me, and I just knew he had me, and it was going to be bad. So I slowed and pulled over to the shoulder, and he went on past me. He had not seen us. From that moment on, I vowed to never do that again, and haven't. Just too dangerous and a threat to my insurance and license. I usually drive my Quad with the Forza controller "on", and the sound is enough for me. At my 73 years of age, I don't need to prove anything about myself or my car anymore.
Be safe out there.... NV
