One thing I should point out is that Charles is not a professional porter.
He's an Electrician, that's his day job. And he tinkers with this stuff in his spare time.
I know people around here blew their loads when he mentioned fiddling with that port for 24 hours, well in this next video, listen to how long he's been playing with the Chev TBI stuff. You're going to need more than one box of tissues.. :)
He did say once he likes to make HP, not just buy it.
