Geesh dude this is amazing! Really you are going so above and beyond what I initially envisioned.
It's not all good news. The crossflow fans I modded are real screamers in the case, and with filter material to stop bugs and dust getting in, they are just unbearable. It could be the smaller diameter tubing I used to make them or the smaller intake. Whatever, they must go!
I cracked the corner of the distributor because of over tightening it. Luckily I have another one, it just needs sanding and polishing. It'll have to wait though as I'm away on business. Just when I was getting into the stride of this thing!
