I went out for a drive tonight and a spotted a SL 55 AMG. We drove around by each other a bit and I headed toward the freeway wanting to see if I could egg him on. He followed me onto the freeway. He was behind me and I gave it a little zing. I exited the freeway at the next off ramp and he followed again. After leaving the off ramp and making a right turn he followed again and got up next to me at 60 mph. I looked at him and waved. He looked at me and smiled. He punched it to reveal a mild exhaust tone and a whistle from his supercharger. I quickly punched it and ran out 3rd and a bit into 4th gear to take it up to about 110 mph. The SL55 AMG hung in there, but I put 2 or 3 cars on him by the time I hit the 110 mph. I was pleased. I let him catch up to pull next to me and he smiled and waved again. We slowed, I got in the left turn lane, he smiled and waved again and drove off. He was with his girl. I was alone with low fuel.

Nice kill! Whats your curb weight with low fuel and you in it?

greg schroeder

Fuel is about 6.6 lbs. per gallon. Having 15 less gallons in the tank is about a 100 lbs. savings. I always drive around a 1/4 tank or less.



SL55 AMG with driver and passenger is about 4650 lbs.



FD with me and with low fuel is about 2850lbs if you begin with curb weight and subtract for weight reduction and then add me to the car weight. I suspect the FD may be lighter than published curb weights, so the car may be lighter.



It's good to have lots of power like the SL55 AMG, but better weight to power and less frontal surface area with lower coefficient of drag gives the advantage.



If the 497 flywheel HP Mercedes puts 420 of that to the ground it weighs 11.07 lb. per 1 HP. That's good, but any FD of 2850 lbs with around 260 wheel HP should be right in there at it's side with 10.96 lbs. per 1 HP. More FD power would be better.



The FD has less frontal surface area and a lower coefficient of drag than the SL55 AMG as well.



On a load bearing dyno my FD seems to put down 278 wheel HP at a touch over 12 psi. I only have DP, cat back, power FC, but have modified forced induction and flow volume of the stock air box, matched the DP to turbo exhaust manifold and polished the interior, and ground the interior welds flush in the stock main cat.



I strongly suspect my modified stock air box produces more power when the car is at speed as compared to being motionless on a dyno.
