If it's not really about tuning or wiring. Then it belongs in here.
For anyone that found the Alan Heaphy/Andre Simon interview very interesting, this video has some great footage from that era, especially of the engine dyno footage.
Looks like they were using cylinder pressure sensors feeding into a box that sat on top of the engine on the engine dyno, as well as exhaust manifold backpressure sensors too. I'm sure those with a keen eye will spot other nuances that I have missed, but anyway, its great historic footage.
I hope some of you guys out there enjoy it as much as I did!
I think you forgot to add the link to the video you are talking about.
Thanks Ludo, fixed now.
