### ⭐⭐⭐⭐⭐ 







  
  
    Cool simple tool
  

*by K***S on Reviewed in the United States 🇺🇸 on August 23, 2021*

Neat tool to give you a idea about what effects what , I'm sure there are many factors the tool can't compensate for , but it's gets you in the ball park .  Fine tuning from there .

### ⭐⭐⭐⭐⭐ 







  
  
    A lot of information available in this little calculator
  

*by L***R on Reviewed in the United States 🇺🇸 on April 14, 2019*

I bought one of these in the 1970's when I began drag racing. After about 60 years, age took it's toll, it became unusable and I needed a replacement.  These are the same calculators used back then and are some of the best for making "quick and dirty" calculations at the track.  The only improvement I could recommend is that the horsepower range be extended to 1500 to 3000 hp to make ET and MPH estimations easier for higher horsepower cars.

### ⭐⭐⭐⭐⭐
