Inlet plenum. The closer to the inlet valves, the more accurate the reading will be. It should be simple to find a hose fitting with a threaded end, then drill and thread the plenum to install.

I watched the video and what I saw/heard was the engine began surging when that cylinder was enabled. If that was the strongest cylinder of the 3, that makes sense to me. The strong cylinder fires well and engine speed increases, the governor reduces engine speed, the 2 weak cylinders fire poorly, t...

No problem with that, as long as the solenoid (starter relay) is on the starter. If it has a remote solenoid (relay), then no.

Many cars are wired this way.

I'd guess the Smart battery was sized to allow for cold starts, possibly down to -40. I know VW did this with their diesels in the '90's. If you are not planning on riding below freezing, you should be able to use a smaller battery. As long as the starter draw doesn't exceed the battery output.

Has the pump been "turned up"? If so, you may have gone too far.

Be aware that if the turbo has to pull too hard, the compressor may surge - create a supersonic shockwave. Do this too many times and the turbo will fail. Often catastrophically. Or so I was taught in aero engines courses 20 some years ago...

Informative and entertaining. Thanks!
