[QUOTE="F8L SN8K, post: 11056832, member: 50367"] There are more variables that need to be answered when discussing which gear for a 1/4 mile run. Just like above stated is all true. You have to know where your car makes peak power at and that will put you in the ball park of what RPM to cross the line which is usually a couple hundred over peak depending on how fast the power drops off. What size is the height of tires you plan on using. This affects your overal ratio. A taller tire has some advantages such as larger contact patch at the same width size and a more side wall when used with same rim size. This can help soften initial hit, allowing to hit the rim a little harder to get wheel speed up as fast as possible. It can also cause driving the car at speed to sway a little more on the big end when doing steering corrections. Weight; 800 rwhp will trap 140mph----in a ~4200#. However a 800rwhp will trap 145 in a 3800# car. There is a formula to calculate out potential MPH in the 1/4 (FWHP/Weight)^.333 x 234=mph I would agree that 3.73 would probably be the right gear for you assuming some of the typical owners modifications/weight.
