Ported my TPI...Pics Added

[Big Ray]

plenum & runner...


have 1 runner & the base left...

took aout 2..5-3 hours to do the first "section"...deciding on how it should go. the last one I did took 1.5 hours...

used some big open flute carbide burrs & flapper sanding wheels. Still needs some fine tuning (polishing)...


will add pics tomorrow
