Earplugs needed for Dyno Day

Yep, still raining here. Last weekend, our local FCA chapter hosted a dyno day. Even though it was raining, a lot of high HP cars came out. There was a Lamborghini 670 LP-4 SuperVeloce, Ferrari F430 Scuderia (2 of them), Alfa 8C Competizione, Ferrari 612 Scaglietti, and Corvette and even a Bentley Turbo Arnage. High HP of the day went to the Lambo at 546. Mind you, this is four wheel drive at the wheels. The Scuds came out at about 460HP and the Corvette got about the same number. My car, on the other hand, probably puts out about 150HP at the wheels right now (maybe even less). New, the carb'd US spec '78 308 reportedly puts out 225BHP, which is about 187 wheel HP. While it would mildly amusing to have my car dyno'd, it would mainly be sad and embarrassing. Kind of gives me an idea of the a**-whooping I'd get if I tried to race any modern F-car.

This was my first time seeing a dyno run in person and it was pretty interesting. The tech had the drivers start slowly and work their way up the gears to 4th. Once in 4th, the tech started the sampling and the driver floored it. The power measurement was done from idle to redline in 4th. I'm not exactly sure why 4th vs. any other gear but perhaps this gives the most accurate reading. Each car repeated the 4th gear run a few times, then did a final run all through the gears starting from 1st. It was really cool to see each car flat out from 1st banging through all the gears. Oh and did I mention that it was LOUD? Here's a compilation video of most of the cars tested:
