wow. Okay, 93 octane and 30psi.
The compression ratio is around 8:1? Just guessing.
I have experience with 2.0L sr20det engines. The most I would trust 93 octane to is around 22psi on most 86x86 engines (sr20/2jz). I feel bad enough at 18psi actually.
Is this a normal routine... with this engine, to push 29psi on 93 octane fuels? I have heard about it, in fact that is one reason I came to this forum; I am investigating this "rumor" which apparently is in fact truth.
has anybody tried pushing an engine like that for 50,000 miles in a daily driver? It seems... abusive. Very curious about the longevity.

That's that amount of boost I run on my X. Dyno's vary too much to say but I've pulled 101 1/8 and 129 1/4 traps on pump at the track. Im in a heavier car then an 8-9. 133+ on pump for an 8-9 seems possible.
I run 29PSI on my Red on 93 octane, I make 460WHP. Maybe 124-126 Traps with that. I have very mild cams, maybe some bigger cams would bump me up to 500WHP or so.

Good lord that's a killer amount of boost pressure guys.
So help me understand your engines a little better, if you dont mind? I think you are all using 2.0L (122 cubic inches) 4-cylinders. I dont know what "red" means or "8-9" is that the generation?
Your compression has to be 8:1 or close to it. Any body running 9:1 though? I am still strictly talking 93 octane. I know you can get away with 10:1 or higher using E85.
And rpm is biggest factor at the end of the tunnel. At 7,000rpm and 17~psi you should be able to squeeze 350rwhp out of a 2.0L assuming 100%VE or nearly that.
because, 122x7000/3456 = 247CFM * (.069) * 2.2 = 375BHP or 360rwhp
Around 350rwhp should be possible. And because math is not good at real world results here is a real world result
Heres a 2.0L engine making 350rwhp before 7,000rpm and turbocharger efficiency is dropping out along with VE so power peaks and holds. Its reading about 10hp high because its set to "STD" but if it was uncorrected it would read around 350 wheel. Stats are (8.5:1 T25 flange turbocharger 256*Duration camshafts 4-valve head stock valvespring and greddy intake/tomei exhaust manifold)
It was running about 17PSI at the intake manifold, tuned on 93 octane. I dont remember what brand intercooler but probably a VSPL (greddy).
So my final question for now would be (and I will look around to learn more of course) Do most of your 2.0L engines performing well at 7,000rpm produce about the same 350rwhp? I understand some of these cars are AWD. Any ideas how much of that power % is being eaten up? I'd like to make some comparisons for the sake of knowledge (for myself please
)
Hope you dont mind all the questions and research here. If you do, sorry I dont mind researching but it seems like yall are wanting to chime in and type a bit which I love and would love to hear from you, personal experience and the like. I'd be more than happy to share mine.

It's good to be in this pursuit of knowledge. The SR20 is a pretty badass motor itself. I think the 2L turbo engine is probably the best design out there in terms of power, fuel efficiency and reliability. The numbers you can squeeze out of them is mind blowing. So many companies have or currently make one. Let's have a moment of silence for our 2L brothers haha
Introducing:
THE ALL MIGHTY!!!! 4G63
Toyota's 3S-GTE
Nissan' s SR20
Subaru's EJ20
Volkswagen's EA888
And let's not forget our Swedish brethren the SAAB built LNF
No replacement for displacement? Meh I disagree hahaha

We can generalize and agree that Heads and turbos make power and bottom ends have to hold it. If thats the case we should just argue who has the best stock flowing Head and sr20 or a 4g63.
i've had an Sr20 with a 280 cam and for some old tech it was pretty efficient.
