A great all-in-one racer’s tool available from Summit Racing is the Hot Rod Calc by Mr. Gasket. This convenient hand-held Street and Strip Performance Calculator is programmed to calculate your vehicle’s performance based on local track temperature and elevation, atmospheric pressure and moisture content. It helps you compensate for the Air Density index and Density Altitude and predicts their effect on your car’s Speed and ET for both 1/4 -mile and 1/8-mile tracks. You can enter your car’s weight or calculate it from a known ET and HP or MPH and HP. It calculates MPH based on weight and HP or from tire diameter, gear ratio and RPM. Calculate changes in tire size and the effect on gear ratio and speedometer readings or you also can enter the gear ratio and calculate for tire diameter, RPM or speed.

It also comes pre-programmed with the most important engine building math formulas. Calculate engine displacement in cubic inches, CCs or liters. You can calculate compression ratio by entering the appropriate engine measurements and you can determine the amount to mill a cylinder head to achieve a desired compression ratio. The Hot Rod Calc computes piston speed, volumetric efficiency (VE), carburetor airflow requirements, horsepower and torque, RPM, bore and stroke effects and a host of other functions. And it features convenient conversions between US and metric units for fluids, weight, temperature, torque and speed.

Mr. Gasket's Hot Rod Calc is the ideal pocket calculator for all engine building and track tuning requirements.

It is powered by 2 long life LR-44 batteries and comes with a tough Armadillo Gear protective case, Users Guide and a Quick Reference Guide for the track. It is the ideal quick reference tool for all engine builders and performance enthusiasts and it is evident that Mr. Gasket went to considerable trouble to provide all the detailed results you could ask for. In our exhaustive Hot Rod Engine Tech review it performed flawlessly, delivering fast accurate results every time. The protective case and tough damage resistant display screen are major pluses for heavy duty use. The function keys are large, well marked, easy to press and the display function is easy to read under most lighting conditions. We rate it a superior value and predict that most users will find it indispensible to their engine building and tuning efforts.
