Joe, 2 things...
1-Don't you think 19psi is a bit out of the efficiency range of the T25? Do us all a favor and find the efficiency maps, calculate the CFM you're running, and see where it lies.
2-Now being what you just put down with all the mods you have...do you think that the dyno on the car from canada on what...9psi where it put down 220+HP w/ exhaust is a little high?
I think 19 is probably too high, I have tried to get maps and cannot find any so far. I would say 16 honesty. I do plan on a water/alky injection soon so then even if 19 is creating a lot of hot air, as long as it is still moving more air the Alky will cool the charge and make it a bit more effecient up there

It is hard to compare my car to the one from Canada- he had a full downpipe- which will make a big difference at higher psi/flow and was running pump gas- pump gas will make more power than race fuel due to the faster burn, however it is the detonation prevention from race fuel that will allow you to push things harder, thus make more power from boost, timing, compression, etc.. Equal cars at a safe pump gas PSI- the pump car wil make more hp. So that being said, his numbers are entirely believable

.. I think he also had a 10-11 psi or so peak settling to 9- he just went with the 9 to make it easier- you know how boards are- if he said peak of 10-11 settling at 9 everyone would get on his case saying he was running 10 psi

..
Hell even turbomatty did 217 at 9 psi and who knows the condition of his motor when he did

.. He may even have the stock DP and exhaust- he would have to chime in here

.. 220+ on pump gas is realistic. I may have made more hp at a lower boost, I may have made more at a hgher psi- this is still all a big experiment- no one knows for sure

.. There are so many misconceptions out there that I am just doing it all on my own and seeing what it will do and how it does it
