12a PP recommended intake runner length
 

I have 44.5mm (1.75") ports and I'm looking for recommendations on intake runner length. The car will see a blend of street and track use but predominantly street, so torque will be a factor. I would rather have decent torque than maximum hp. I'm not saying hp isn't important but I would prefer a happy medium.
The setup is utilizing a Weber 48 IDA with 44mm venturis.
I intentionally left the intake tubes a bit long so that I may cut them to desired length.
After I figure out the intake I'll work on the exhaust :)
Any and all help is appreciated.

Racing Beat already makes a PP intake for your setup.

Yep, and I have one which has been shortened by a previous owner. I'm looking for the optimal length to meet my goal as described above. I assume the racing beat manifold was designed with mainly track use in mind. Not to mention there may be others with first hand experience to share.

Anyone else?
