If there is anything to gain performance wise it's probably in spool and who is really going to notice 50rpms

I'll start with I'm no expert but a couple things to note. First off, of course you are going to get some gains by adding exit diameter cuz you are decreasing the friction loses. The 3" and 3.5" in the article you linked are not like for like comparisons. They don't list what type of muffler was original on it with the 3". Also you can see that the newly fabricated 3.5" is more of a straight shot with less bends in it. More bends equals more friction. Although they don't address it, I'd bet they lost torque going to the larger exhaust.

I wouldn't get carried away with the fact that you 'only' made 509whp. Your numbers aren't much different than any of the other cars running a BP kit. For ex: jlo made 52Xish whp at 11.5.psi, that's about spot on where you are for a 11psi max and he's running a FI exhaust.

And then you thrown in all dynos are different and all tuners tune differently with different goals.

That is great, 500ft/tq at 4,300rpm.

That is a lot of torque. A little too much for my comfort lol. I turned my boost controller off and am running the wastegate pressure of ~7psi because I'm scared of popping my motor. I guess the natural thing to do now is to throw some forged parts into the motor. It will be a while before that happens though. I need time to recuperate money and my relationship with the wife lol.

I have to ask, what are your real concerns? Your 532/497 is the best numbers I've seen on a BP 37HR kit. So why do you say you aren't making the power of the dual exhaust guys?

Idk, maybe I'm just being crazy. My power was made in 5th gear which also reads a little higher than the typical 4th gear pulls. Someone here made 550whp. I don't remember who it was and idk why I'm so hung up on 550. I know there are so many variables that can't be recreated and comparing dyno sheets online is about as accurate as (something terribly inaccurate). In reality I really have nothing to complain about. The car is more than a blast to drive, which in the end is all that matters. Im just being complicated and dumb lol.

Dude...stop and enjoy the thing that is a boosted VQ. You'll dominate 99% of the cars you come across :driving:
