dsmperformance,
I've seen you making similar posts in several threads, but without any real depth.
It would be great if you could expand on this and clear everything up.
So we now know what the issues are. Tell us more. Hows, Whys, etc.
Why is 19 psi NOT a concern on the Evo? I still think it is. Why, specifically is CFM the real concern?

Its not all about PSI anyhow! You can have pressure but you also have to have flow. Its a combination of PSI, CFM's, fuel enrichment and proper timing.

Even though the new 2.5 hasn't been tested yet, we all know it will handle substantially more than 14.5 psi boost. That nothing for the setup its got. Just as 13.5 wasn't much for a stock WRX. Subaru always leaves plenty of room. Also the IHI series turbo can easily push 18+ psi boost.
I can't wait to see how fast the STi is going to be with just exhaust mods and some engine management/boost increase. Its going to haul butt.

PSI is a measure of pressure differences. PSI does not have a direct relationship to power output. CFM does. CFM(cubic feet/minute) is the measure of actual air flow. You can run a tiny turbo pushing 25psi which will not have the same CFM as a much larger turbo at say 15psi.

Makes for an interesting reading.

Also, check the latest issue of sport compact car. It talks all about turbos and sizing for the engine. A Turbo spins a turbine to pressurize the air. The more pressure the higher the RPM of the turbine, the higher the rpm the higher friction, the higher the friction the more heat that is generated and eventually the effeciency of that entire equations starts to go down. My little RX could push 14psi out of the turbo, but it heats the air so much in doing it that I would actually make more power running 12 or 11.
