Going back, it looks easy now because there is so much non-credible BS going around now.
I will take this gem found in page 2.
Further to that post. That sort of rough guide only works when the turbo manufacturer is not talking BS to you. Take Garrett flow maps as gospel. Take borg warner flow maps as gospel. Take IHI maps as gospel. Most other numbers tossed around are complete horse ****.
I will take this gem found in page 2.
When you look at a website that shows how much HP thier turbo is good for realize that the spec is for a piston engine, at the flywheel, and peak boost. Take thier HP specs, multiply times .80 to convert to rotary, then multiply that times .85 to convert to RW. That is appx what you'll make if you max the turbo.
