Message Ok since this is my source for the best information, I thought I would ask this question. I have read over and over that larger turbos make more power at the same psi, mostly on honda and mazda forums, they all say the same thing.

Now I have been reading everything in ztechz and what he says is what I was to believe was always true. If you have 10 psi in the manifold regardless of turbo size then you are creating the same power. Now the small turbo will have to spin faster to create the same volume of air, but how much heat is actually added and does that detract that much from the power output? I am not sure.

Also has anyone ever seen empirical evidence such as running the same car with both large and small turbos with equal pressure and dynoed the results.

In my opinion it makes no difference except the possible added heat from the smaller turbo. Can someone explain exactly what is going on between two different size turbos? Thanks
