Then why not correct it to SAE and post those numbers originally :shrug:
If the dyno isn't generous and you factor in the typical 15% Drivetrain loss for a manual and a 20% loss for an auto. Fifty's car would make 531 HP and WBT's car would make 497 at the crank yet they run almost the same time and wbt runs 3MPH faster then Fifty's. To me just simply saying it is an auto so it faster is understandable in the MPH considering wbt doesn't loose momentum when the car shifts gears but then they shouldn't run the same time unless wbt has the lighter car. Can someone educate me to this then?
one thing is you math is off. its closer to about 18% for an auto with stock Drive shaft and about 17% with a 1pc aluminum. your right about the manual thoe.
