I've been here a while now (even before buying my car, 2 years ago) more as a reader than a commenter (partially because I'm french canadian so I'm more confortable reading than writing or worst, talking!) and there's two things that strike me the most about the performance threads that I read:
1. I've not seen much talk about turbo efficiency and flow charts when it comes to swapping the stock turbo to whatever options there's available (Hybrids and Big Turbo) but so many seems to stick on PSI obtained and what not.
2. Again, everybody talks about big intercoolers but nobody talks about what is the right size and pressure drop. I see massive intercooler like the Bravo and can't help to think: is it really needed? Is it efficient, for the, what, 350-400whp it'll see at most, or is a smaller one would do the same? I see plenty of highr whp builds in other tuner scenes that don't use that kind of size and simply don't need them.
Now, I start this thread to talk about the first point and if you have half an hour to spare, I suggest checking this video about turbo efficiency.
I understand that not much information is available for either the stock nor hybrids or even some big turbo when it comes to compressor maps so we could compare apples to apples. But once again, pretty much all I see is talks about maximum boost attained. I just wanted to get a conversation going about what I think is a more relevant piece of information (flow rates and efficiency) when deciding which way to go when buying a major upgrade. What do you all think about this?
