i think the ecoboost are ko3's, which are smaller than a t25. I could be wrong.
even smaller lol
Turbocharger
V6: Dual Honeywell-Garrett GT15
I4 2.0: Borg Warner K03 low inertia integrated turbo system
I4 1.6: Borg Warner KP39 low inertia turbo
alright...
Max HP = ft-lbs * RPM /5252 = hp
max HP = 600 ft-lbs (20% for WHP) * 2000 rpms / 5252 = 228 hp. ~ 23 lbs/min
4.8L with 84% VE (observed stock based on dyno sheets) @ 2000 rpm @ 20 psi = Engine airflow requirements 23.19 lb/min.
So it looks like you need to make 20 psi by 2000 to hit your goal (i think)
Twin garrett GT1548's will put you on the map at 20 psi with 11 lbs/min (each). you'll run off the compressor map by 3500 rpm.

No youre right, just my point was no one wants to look at math and facts, they just want to internet race from one of their cousin's buddie's neighbor's cars they saw a video of on the dyno.

Great post and exactly why this goal is unreasonable whether this math is spot on or not. Don't be afraid up downshift to reach your 500. It's the more healthy option for your engine.
