Instead of multiple post, try the link if you want to see more pics. There are also some pics of my TT BMW 335i.

Eatmyclutch is an unknown quantity at this point
Bestiality should be illegal. How much power are you putting down to the ground?

I was off, it was 14.92...call it 15psi...not 14.5

You question the difference but 15 psi is 50% more than 10 psi.....

You are right, it is only 20% difference...... I would be hesitant to even use a rule of thumb since so many other factors influence hp other than boost such as AFR, timing you name it....basically the whole tune...... I just figured the guy posing the original question was calling me a liar. Thanks for the correction.

On an engine with a high VE it is not uncommon to see over 15hp-per pound of boost (in this case 18hp). There are a lot of other factors and though you most the time see gains of 10-13hp-per pound it IS possible.

Rotory horsepower gains and air-flow
Efficiency gains in rotories never cease to amaze me when increasing airflow.
My built 3-rotor with a Borg-Warner S-400 turbo acheived a 100 horsepower gain on the dyno at 17psi when the exhaust system was simply removed at the downpipe. This was a quality exhaust with no cats, not stock! My NA 2-rotor 6port gained over 40hp by removing the cats and replacing the exhaust with an Apexi GT N1 and a K&N intake. That is on a motor that comes stock with only 148hp!
