hustler Posted November 1, 2011 Share Posted November 1, 2011 Are we over the FI Miata lb/hp penalty yet? I'm getting tired of pulling BMWs and Mustangs out of corners and and getting bus lenghts put on me by cars in the same class. Quote Link to comment Share on other sites More sharing options...
speedengineer Posted November 1, 2011 Share Posted November 1, 2011 Acceleration or top speed? I do not think the curves exist for your examples. Remember TQ and hp cross.at the constant. 5252 I think Either accel or top speed. Well, either once you are in the upper rev range - technically the torquey motor would be better off the line, but we don't do standing starts in TT. That's why torque ft-lb numbers aren't relevant in road racing. Let's look at it from another angle. From physics 101, work=force*distance. Power is work per time. Therefore power is also force*distance/time. Distance per time is simply speed. So, below is the simplest equation you will ever see that you can use to calculated the acceleration of a car: (Force accelerating car) = (Current whp)/(Vehicle speed) (with proper unit conversions of course) It is that simple. If you know what your whp is at whatever rpm you're at and you know the vehicle speed, you can easily determine the drive force on the car at the wheels. Notice how torque is not present in this equation. Quote Link to comment Share on other sites More sharing options...

drivinhardz06 Posted November 1, 2011 Share Posted November 1, 2011 That's why torque ft-lb numbers aren't relevant in road racing. They are in the rpm range that you're engine will be operating in. (which should be a very narrow band unless your transmission ratios really suck) Quote Link to comment Share on other sites More sharing options...

cucamelsmd15 Posted November 1, 2011 Share Posted November 1, 2011 Other than that just make sure your bar isn't hitting something causing the links to fail. Dont want to speak for Vinny, but Im pretty sure that is his issue (as well as mine). Quote Link to comment Share on other sites More sharing options...
Cobra4B Posted November 1, 2011 Share Posted November 1, 2011 Last I checked engines produce torque and horsepower is merely a function of torque and RPMs... thus torque is rather important Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted November 1, 2011 Share Posted November 1, 2011 torque at the RPMs you use on track being the MOST important I win the thread! Bow to my greatness muhahahahaaa Quote Link to comment Share on other sites More sharing options...

TurboShortBus Posted November 1, 2011 Share Posted November 1, 2011 My front license plate frame has canards on it, and the rear license plate frame is shaped like a Sopwith Camel. Points? Mark Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted November 1, 2011 Share Posted November 1, 2011 if we let Mark decide points/no points and the amount of said points every car will be in TTR or more stock than my TTF/PTF mobile Quote Link to comment Share on other sites More sharing options...
