DARIO DOES STUFF's video: Mazda RX7 intake manifold restoration and test

during the first part of 2020, before Italy's lockdown, I did this fun experiment: making a "sonoramic commando" style of intake on my RX7, using my existing Fitech EFI and an "S5" intake manifold, actuators and all... I later aborted this project since I realized that despite the fun in making it, it didn't give anything better on the power band, and the driveability was much worse than before. If you want to do something similar, just put the injectors downstream, where they are supposed to go, and not 1 meter away from the engine, also, the Fitech EFI doesn't behave when put on it's side 90°, but should always remain as vertical as possible. If someone in europe wants this manifold, just dend me a message. Thanks for whatching :)
