(TURBO) What makes/supports 500-550HP reliably for our cars?

Or you can just watch my videos.

That GT3

Do you run more than 5.5psi on the street just so you have more usable boost/power, or are you taking the car to 7k all the time?

I am now permanently on my high boost map. 7 psi at spool (wastegate) ramping to 12 psi at ~5500, and then holding to stock redline. I'm also more or less permanently on ethanol, since I don't run events that mandate gasoline for the car with the BRZ anymore.

I have a 7800 redline, although I very rarely rev that high, and my wastegate duty cycle skyrockets up top, resulting in boost taper.

I'd say the car sees 7400 at least a few times every time it is warmed up.

Seeing 112mph down the front straight at BRP is depressing; my roommate's BRZ with a more developed version of my turbo setup sees 120+ there. Same turbo, same boost level, but a few years more knowledge and some refinements. Hell he's even on the original GReddy intercooler.

Whoa.
It's cool to see so much progress still being made with these cars after being out more than eight years. I doubt I'll ever make any real power mods to my car, but it sure is enticing seeing your progress.
