Alright, here's a new one. This one actually pays the bills. Making sure a product line I'm working on doesn't violate the "this device may not cause harmful interference" statement you see on things. Although this is an industrial device so the levels and frequencies aren't the exact same.

10M radiated emissions in anechoic chamber. It's dead quiet in there and ZERO cell signal.

That is pretty cool. I have traveled up to Michigan to work in some wind and temp chambers, but never a sound chamber like that. That is pretty cool. My brother and I built a recording studio in his home and it looks like a MUCH smaller version of that. Cool to see.

Is that what they call an "Anechoic Chamber" ? That could probably swallow the noise of a 600 inch BBC with open headers EH!

Yes, it's usually called an anechoic chamber. This one in particular is for electromagnetic waves instead of acoustic, but the guiding principle is very similar so it does absorb sound very well too. The foam is impregnated with carbon to make it electrically lossy, though.

The antenna in the picture picks up all the electromagnetic radiation coming off the test device to make sure it's within limits.

It's a Porsche 928 S4 engine. Take a look at John Kuhn's youtube channel: https://www.youtube.com/watch?v=cxn-LxwsrnU

The op to be shown next will be the intake port matched to the heads.I find it is an easier job when no pistons are in the block as you can put light up the bores. I am not using these AFR 227 heads on this engine But the ports are in the same location as the heads being used.
BTW have had some really good results with these AFR 227 CNC headsa right out of the box.
The last set made over 1.42 ft/lbs per cube on an 87 octane fuel build. This was while Tony Mammo was still at AFR. Tony's comment 'How Much? Holy S**t'

what are the valve guide looking pieces in the valley?
