Good content on this channel. :) May I offer one turbotip? If you look at the compressormap for an old turbo and compare that to a newer turbo, after you have colored the 70% islands on both of them green, it becomes very obvious why no one should use a stock ancient Rajay or Roto Masteres turbo, ever. Ancient turbos have really bad design on the wheels and therefore they deliver very high charge air temperature and back pressure and this ruines the base engines potensial for delivering good results.
Do you happen to know a source for info on those Rajay turbos themselves? I have one and want to know if it'll work for a project or if it'll just be shelf art. The little bit of info I've found on them is on the generic side.
