I guess I need more gear then.
Both my nitrous and N/A time = higher than 1335.

The more I mess with this the more I find it's pretty general and doesn't seem to take into account things like traction/60' times .. I think that the person that came up with this was basing it off of a perfect launch on slicks.

Discovered that these formulas were pulled from the FTI site as follows:
Compute the Ideal 1/4-Mile Pass Elapsed Time X MPH = 1335 Examples: 13.35 x 100.00 MPH = 1335 12.00 X 111.25 MPH = 1335 If the factor is more than 1335, add more rear gear. If the factor is less than 1335, reduce rear gear How to Compute Your Miles-Per-Hour MPH = TD X RPM / GR X 336
MPH = Mile Per Hour TD = Tire Diameter GR = Rear Axle Gear Ratio RPM = Engine Revolutions Per Minute
