How to Make 900+ Supercharged Horsepower on a Blow-Through Holley Super Sniper Stealth

Holley’s Super Sniper Stealth can support 1,250 horsepower and 21.5psi of boost so we teamed up with ProCharger superchargers to put one to the test on Westech Performance’s engine dyno. Follow along as we make big power out of this 377ci small-block-chevy with bolt-on parts!

Ya lots of good info missing. But interesting none the less. I would have liked to know what fuel and what the injector duty cycle was at.

I feel like all I do is update firmware! The firmware on the dash isn’t working, but before I can update the firmware in the dash I have to update the firmware on the ECU, but I can’t update the firmware on the ECU until I update the firmware on the 3.5 touchscreen. And guess what none of these damn firmware updates work. Three weeks into this shit.

Will this learn with boost also?

I have the Holley sniper Efi. 650 version. Is it 650 crank or 650 wheel capability?

What if you can’t drive your drag car around for it to learn?

You only mentioned it was a small block, I didn’t hear the displacement though?

To bad you can't run e85 on the sniper efi.

Can the injectors be upgraded to go beyond 1250 hp?
