We have seen 5 or 6 videos lately of people testing out little plastic turbocharger keychains with compressed air, and while those little toys are cool, this is a hundred times better! This is a real, operational mini turbo that helps cram air down into the RC car it is installed in! Just kidding, folks…this is still one of those keychains, and it doesn’t do a lot more than just look super cool on this RC car!
