Induction Wave Tuning Calculators

These induction wave tuning calculators will determine the most efficient overall length of the intake runners to optimise the intake system. This updated calculator allows the user to decide how many induction waves they want to calculate for. The optimum is the first wave, however, it should be recognised that both the first and second waves are usually too long for most practical applications - NASCAR engines use the third wave. We recommend you start at the third wave and go from there. Just enter the number of waves in the second box. Do as many calculations as needed to get a workable compromise between performance and the practical space constraints on your vehicle. Once you have found the most practical dimensions, all you do is measure the current intake runner length and subtract this from the length advised in the calculator(s) - the bit left over is the length of the velocity stack. This will tell you how long the velocity stacks should be, but remember to allow about a half inch so the stack can slide over or inside the end of the runner (usually the carby or throttle body). We have two different calculators, depending on which measuring system you prefer (we have both kinds - metric and imperial).

Remember: Our velocity stacks are metric, so you will need to convert the ID for yourself.

Please Note: Thanks to a very helpful customer, it now works with major browsers.
