Yeah, PY... the Twitter of the Pontiac world.

The BW475 is a very good turbo, very spicy in the top end and also very heavy on the corner it's mounted. But, you know, it's much easier to just buy your turbo because it's the first one that pops up on Google Ads. No need to crawl through the maps of many turbos, factoring in converter, gears, tire/wheel sizes, car weight, fuel quality, target boost pressure, piston ring gap and engine management but most importantly, one should never comment on the PY boost section in fear of upsetting the retired boost engineer. But when the advertisement said I would make 635whp at 10psi on the hub dyno with me tuning it in a car designed purely for the street that also just finished a 600 non-eventful-and-reliable mile trip because the wifes Subaru has head gasket issues, god dammit, I just had to have it.

Have fun guys! I'm out.
