Just wondering what this is...I know it can vary from build to build depending on all types of things....but, just wanting an avg...
I figured mine up, and tell me if im doing this right...
took my baseline of 230 and subtracted it from my boosted max whp of 385 and got 155whp as my overall increase....then took that and divided by 8.14 for 8.14psi that was confirmed on the dyno which give me 19.04..or in simplest form: 19whp:1psi ratio....
does this sound right...? im a 10.0:1 CR 243 heads and 325ci

Also the math will only work on your setup because 15 psi on a motor that eats 100 lb/min of air is different than 15 psi on a motor that is eating 80 lb/min of air. Obviously the motor that consumes more air will make more power per psi. The amount of air consumed depends on tb, intake, heads, cam, compression, etc. Lots of variables.

^ Exactly.
It's all relative to overall design, engine specifications, conditions, tuning and most of all; turbocharger volumetric efficiency.
A GT3582R producing 20psi on a 350ci engine will not be nearly as effective as a GT4202R producing 20psi. Once again, it's all relative. A battle of design and EMAP versus IMAP.

Though there are many companies that will claim some average number gain, there are way too many variables for the numbers to have any meaning.

Just like you would give a customer a ballpark figure on what it will take to fix their car without actually having it there to diagnose it. You can count on anywhere between 20 -25hp per psi. Only as a given rule of thumb to go by. Too many variables in all the different set ups to account for to be accurate.

Just my opinion, I'm not arguing with you at all, because your statement was obviously correct and logical.
Agreed.
