No,



this is why somebody with a t04s makes 350rwhp at 15lbs of boost,



and somebody with a t-78 makes 400rwhp at 15lbs of boost. Again flow is not the same as PSI

 

sounds like you have experience with this, so i'm sure you're right, i really have no experience with it.



but if you could explain it to me i'd appreciate it. logically (to me.... thats not saying much) squeezing more air (from a bigger turbo) through the same sized hole wouldnt actually make more flow, just more pressure.



Thanks,

All rfreeman27 is saying is that a bigger turbo will move/flow more air at the same pressures as a smaller turbo. Like the comparison he made with the T04S and the T78 yes the air is going in the same size hole, which would be the port, but let's say that both turbos are running 14psi. Simply because the T78 is larger and moves more cfm's it will out flow the T04S. Flow and pressure are totally different. If you had a small turbo that can run 20psi+ but can only flow a low amount of cfm's it would not be as efficient as a larger turbo that can flow that same amount of air at a lower psi. Hope that helps explain things a little better.

 

I agree with j9fd3s. 13bt



I've got a 13bt with a T66 running 15 psi, street port and we've got 436hp at the wheels.
