Re: WITH TRANNY

An Auto tranny will be relatively cheaper, and will usually give more consistant track times.

Re: WITH TRANNY

autos are usually the better choice for racing.. less mistakes and easier to get traction.. unless you can drive a stick very well..

Re: WITH TRANNY

automatics multiply torque-using a high stall the torque can be much higher at the starting line than a stick. i've seen low horsepower cars overcome this advantage but it's hard to beat even though with a stick once moving the power is more directly through eating less hp from the engine. street racing i'd go with the automatic because there are no track conditions-just how much you and your friends pour out vht- and on the streets chasin is racin. most street racing is done at night with dew on the ground with no prep and bangin through gears will cause a loss with lack of traction. don't ask me how I know all this.
