🤯 8 years of garage engineering to build the ultimate jet-boosted VR6... 💥🛠️ Hearing an actual aircraft APU turbine spool up inside the cabin of a street car is equal parts terrifying and incredible. Custom switches, aircraft-style gauges, manual fuel shutoff valves, and a high-rpm whine that requires hearing protection—this project is pure mad scientist energy. Kelby is taking it step-by-step with the upgraded turbine to avoid blowing up years of painstaking custom work. What’s the wildest engine swap or forced-induction setup you’ve ever seen? What are your thoughts? 🤔💭 ( Media: @jetboosted_vr6 ) #audi #quattro #vr6 #engine #cars
