Not exactly my car but I brushed 3 years worth of dust off my flowbench, re-learnt how it's supposed to work, tasted 3 year old water when attempting to replenish the manometer (not high on my list of recommendations), fired up all eight vacuum motors (burnt out the controls for a couple) and did some testing on some restrictors.
Need to do some industrial strength rewiring on the control panel so that it'll run at full strength again but it's good, interesting fun playing around with various ideas and seeing a physical difference. All while trying to not go deaf or lose items of clothing into the test piece! 8x ~2000w vacuum cleaner motors through a 4" bore creates an awesome amount of suck!
