50mm PP port intake length?

Working on a 50mm PP port project, N/A.

Anyone have good intake length numbers? We will try a few, but don’t want to start blindly

have you seen Mazda's SAE paper there is 900032 and then one for the R26B.
on the fixed length engines they ended up around 370mm from the intake flange to the tip of the trumpet, but it makes such a big difference you will want to try shorter and longer lengths
