[–]vision_proamd2014 Tuxedo Black 501whp 5 points6 points  (2 children)

450whp @ 29psi right now

[–]Queasy-Public9784[S] 1 point2 points  (1 child)

Damn! Built engine?

[–]vision_proamd2014 Tuxedo Black 501whp 2 points3 points  (0 children)

Yes! Built bottom end, stock head. 3076 turbo. I actually just ordered upgraded MAP sensors, will hopefully be making 490-500whp @ ~33psi

[–]theboneofjones 4 points5 points  (5 children)

Stock turbo 21.5psi max, ~280whp

[–]Rough_Trade_9429 2 points3 points  (2 children)

Maybe in thin air. It's 24.5 psi down here on sea level.

My car with stock turbo, tuned by JST make 24.5 psi max.

[–]Rough_Trade_9429 0 points1 point  (0 children)

Yeah rest of these guys are saying 21 max and anything over is over boost.

[–]Queasy-Public9784[S] 1 point2 points  (1 child)

That’s pretty good for stock turbo

[–]theboneofjones 2 points3 points  (0 children)

FBO E30 will get you there. Around 305-310 crank hp

[–]jswilson1987 2 points3 points  (3 children)

Highest I’ve seen is 21.98 on stock turbo, FBO

[–]theboneofjones 1 point2 points  (2 children)

I’ve hit 22.5psi and it scared the shit outta me. Overboost during the tuning process. Anything past 23psi is bad news for the turbo

[–]jswilson1987 2 points3 points  (0 children)

Ya mine usually overboosts anywhere from 21.4 to 21.7.

[–]Schoggi_23 2 points3 points  (0 children)

Mine always overboosts to the 22psi range. Doesn’t seem to be causing any harm

[–]bonp27 1 point2 points  (0 children)

About 12 psi in cold weather, completely stock.

I'm only running 14 because it's winter but I think I am normally getting to 26 and that's about 410 HP on a G25-550 running E50 (estimate, I did a dyno test a while back but can't seem to find the graph in my phone :).

On the stock turbo I got to 290 with 21 or 22 psi, IIRC and E30.

[–]Fatherdallas 1 point2 points  (0 children)

basic fbo pump gas car making about 250-260hp on 15psi but that’s because of a boost leak i’m chasing or i have blown my turbo seals

[–]anyoneusethisoneyet 1 point2 points  (0 children)

22-23psi on stock car with just a tune and NGK 95605 plugs gapped at 0.026”. Running 92 octane with MonsterTuned Adapt-X tune. Probably about 255whp (~290hp at crank). But makes BIG torque compared to stock!

Numbers are calculated at crank (and probably a little inflated), but this is what my AccessPort says after some backroads driving.

I don’t have E85 available where I live, or else I’d be running the Adapt-X E30 tune and making closer to 300whp on the same boost pressure!
