Here's my old setup from a couple years ago, currently upgrading the rear end, the fuel side from cell forward, bigger blower and carbs.
Foster Supercharger sound mod.

Went from 192/132 stock to 400/262 @17psi. Doubled the numbers on pump gas
What are the numbers on it?

Haha well I also had my tool box remote hanging on a cabana clip so I don’t forget them for work. If I do, can’t open my box. That and the conjunction of the vibrating cracked dash lolcool
& curious, how much stuff do you have hanging on your keychain?

but my vehicles are supercharged. The mod is only to make the sound more audible inside cab not outside.

Ok, I'll forgive you then..lol
I thought you were doing something like those fake turbo whistle things that the import kids put on.
Nice dyno numbers by the way, doubling is quite impressive, what other modifications were made besides the supercharger ? I would assume fuel pump, injectors, exhaust ???

14.7psi is double the atmospheric pressure, so running that much boost should double the unboosted output of the engine.
The rear wheel hp numbers on my mustang before the blower was 240hp and I think 290tq. At 14psi boost the hp was 410 but they ssid if I would've taken it up to 6000rpm instead of letting off at 5000rpm, it would've peaked at about 460-475hp.

I was making 50 hp per psi of boost on that engine in the video, I was only able to get 3 lbs boost with my pulley/belt combo (4 pulleys and 2 belts) that I took with me, my belt wouldn't fit the next combo of pulleys unfortunately. I wanted to limit myself to 6 lbs with the 93 octane I was using, just about the limit with the old roots setup.
I should be more efficient with the new setup, now to just figure out how to plant it...lol

1000cc injectors, 320lph fuel pump. Aem V2 EMS, headers, test pipe. Kept OEM exhaust. Haven’t found one I like personally I think this sounds perfect. Upgraded the clutch, changed the flywheel to the 1st gen years, 14.5lbs vs 22lbs, larger throttle body. Installed Big brake kit and SS lines

Which flywheel do you have now, the heavier one for more kinetic energy or the lighter for faster revving? Looks like you really went through everything to compliment each other, which is what's needed, it'll sure find the weak link in a hurry.

I have a 04 which is considered AP2. These years redline 8000rpm. And the flywheel weighs 22lbs. Ap1 flywheels weight 14lbs. Before 04 ap1 S2 redlined at 9000
so I opted for faster reviving since the supercharger can make up for the difference in weight. Also when I tuned my redline was changed to 8800. So I have a screamer of a sports car.
