The result wasn't exactly what I was looking for, but it still did pretty well. Long story short, 571awhp, 495wtq, 40psi around 4,400RPM, peak torque around 5,600RPM.
FP says the HTA compressor is good for 40psi, so since I spent the time and money to get the car to where it would support that kind of power and fuel consumption, I wanted to see what the turbo would do.
The turbo is the DSM76, which is the HTA/billet version of the beloved 3052.
5 years ago, the car made 557awhpand 445ftlbs at 34psi. Since then, the only thing that has changed is I added a recirculated catch can, redid my intercooler piping, changed to high impedance fuel injectors, and put a ton of miles on the car with a couple near complete loss dissasters.
The turbo spooled just a hair later than before but made produced a better torque/power curve, but the power fell off on top more this time around. Like it did 5 years ago, it dropped to 29psi or so out past 8,000RPM.
Also, the highest HP pull came from what I though was an overly rich AFR at 11.5:1. I leaned it out to around 12:1 and power dropped a little. The car is on E98.
What's most impressive to me is the torque curve. It made 495ftlbs at 5,600RPM. 40psi came on around 4,400RPM.
This is a basic Eagle/Mahle 9:1 motor with a small plenum JMF intake manifold, FP turbo manifold, and ETS 4" intercooler, and ported head. The motor now has around 45k miles on it where the pulls I made 5 years ago had around 5k miles on it. I feel that the age, wear, and tear on the motor play a role in the lower than expected numbers for an added 6psi (or, the turbo was near maxed out 5 years ago at 34psi, which isn't exactly unbelievable), but 571awhp is pretty decent for a bolt on 30R in my opinion.
Yesterday's dyno time also marked 6 years since I bought my Galant.
I have to thank Lucas and Aaron at English Racing for the dyno time and the help they've provided for the last 6 years.
