Winisd port configuration

toenail · 28th January 2006, 11:07 AM

Curious about interpreting the port recommendations from Winisd Pro alpha. Increasing the number of ports increases the length needed. Is this new length to be divided by the number of ports or is each of the ports supposed to be this new length? Trying to lower rear port air velocity and avoid "tuned pipe".

Each vent needs to be that suggested length.

As you can see, you have to make a compromise.

Putting more ports lower the strength of the air spring so you need to make every port longer than before.
