It's free. Me and him are buddies so it's no big deal. I see where you're coming from. I wouldn't sell plans until I know my plans are perfect.

Thas a lot of port area. 20 sq inch / cu foot seems like a lot for daily. Does it make that much of a difference from say 12-16 per cu foot?

And yes I agree, that port area is extremely excessive.

Would a port area of 64sqin be a little more appropriate?

yall are gonna have fun tryin to fit that in curtis's trunk....my type r box was 22.5 x 33 x 14 or 15 and i couldnt go any bigger...

i also had to take out the lower latch too...

This will work. We've measured many times and this will fit for sure.

 

[matt_martin87 10+ year member]

I switched up the port area to 62.5 sqin.

Here's a quick look.

if u build in the trunk it will...the trunk opening is a whole other ball game..

Yes. My 2x12 mag build I just did is working very well with 16.6 per cu foot. I was worried that was going to be too much. Turned out just fine. Beyond fine. I really like my mags.

The ~15.5 per cu foot in your last plan is within the recommended range, should be solid.
