OK, I guess I'll share one
I was in my early 20's and had purchased a well-worn '87 Mustang GT T-Top. It had a bone-stock 302HO in it, I put underdrive pulleys on it, equal-length shortie headers, an electric fan swap, aluminum driveshaft and a big 'ol honkin K&N cone. It had 2.5" exhaust and no cats into a set of very well broken-in flowmaster 40-series mufflers. It was loud. REALLY loud.
We had two groups that hung out downtown, the domestic guys and the import guys. We didn't mingle.
On the domestic lot, my car was not one of the fastest, which were owned by a number of my friends with H/C/I combo's on their 302's with some form of power adder, be it nitrous or a supercharger. I eventually did heads/cam/intake on mine, but that wouldn't be for another few years.
At this time, my old girl would run high 13's at just over 100Mph. These other cars were all deep 12's, high 11's. Of course there were slower cars than mine, but my car was not what I would consider fast at this juncture, it was a lot of fun however.
The Import lot consisted of a more diverse, but significantly slower cross-section of cars. These were folks that thought a K&N added 20HP and a catback another 50. Nobody had a power adder and the cars were all trimmed out with the best speed-adding bling from the Mr. Gasket isle of Canadian Tire. Whether it was a blue cone filter, bright yellow plug wires, or anodized blue oil fill covers, you name the high performance part, and these guys had them!
One of guys had a Hyundai Accent that my Co-op student had successfully decimated in his mom's Plymouth Breeze. He was eager for redemption and so he egged his entire entourage into having a go at my old Fox body. Light-to-light we went, the old 5.0L dishing out football fields of humiliation. Upon the completion of this epic, we congregated in the Canadian Tire parking lot where my car was surrounded by the confused and curious telling me my car must have been 300-400HP. When I corrected them that it was 225, they could not believe what I was saying. I popped the hood to reveal the stockness in all its glory and was met with gasps as to the prodigious nature of my K&N cone with must have added "50HP" according to one onlooker. When I stated rather firmly that the filter added nothing but noise, they would not have it, that could not be!
Weeks later, a legitimately fast import came to town. It was a Civic with a built B16 or something in it, and a very large hit of nitrous. One of the old domestic boys in an attempt at scathing condescension said he could beat it with his winter beater, which was an IROC Camaro with a 305. He did not fare well. This began the escalation of what would result in one of my more modest friends, whose Fox would run mid 11's at >120Mph like clockwork ask for a race, and was denied, when the owner of said Civic indicated that his car ran 12.8's on the bottle and wasn't going to waste his time getting spanked by an 11-second Mustang. The other boys, having no idea as to what a timeslip meant, but with their dander up over my friend asking if anybody wanted to race "that little black coupe over there" were quickly shushed by their associates, and there was some serious emphasis put on telling them not to race my car which was, ironically, probably the slowest domestic in this conflict since the IROC had gone home
