Peak Intake Flow Rate/Peak Horsepower Calculator


Please enter the displacement in metric or imperial...
Use Imperial   Metric
Displacement inches or cc
(For rotary engines make sure you use the mechanical capacity not the taxed capacity)
       
Please enter the volumetric efficiency or boost depending on your aspiration type...
Aspiration Type Normally Aspirated Turbocharged/Supercharged
Volumetric Efficiency % or psi boost
(Unmodified engines are about 90% / engines with modifications are about 95% / seriously modified engines can achive 100% or more)
       
Engine Type 4 Stroke   2 Stroke or Rotary
Peak Power Engine Speed rpm    
       
     
       
Peak Intake Flow Rate 0 cfm   0 litres/sec
Peak Horsepower 0 crank hp    
Please note, the Horsepower figure is a rule of thumb approximation, unlike the Flow Rate figure.

This conversion utility was jointly developed between FrozenMist and www.mk5cortinaestate.co.uk to aid you in configuring your vehicle to get the most out of it. To the best of our knowledge it provides a good quality of accuracy but we do advise that you should always double check your results to avoid any problems. We always welcome any advice/experience that people can give us to help us improve on these utilities so please contact either Mike or myself using the links below if you have any contributions.
