This is a way you make it more efficient. Blueprint is orange, yess. BUT, it works. It saves on oil with the gaps and circular designs, yes. it does take a little longer to warm up, and it's annoying, but if you want it, you can get it. Hope this helps for all my friends with time machines!
Note: I have no clue what I was doing. I made part of this in bed and part of it in school, and I woke up to find this, completely clueless. I may be crazy, I may not be crazy, but who's really to say? Also, If you want to use this, feel free to. Credit is optional. Please hel.p.
