It's 100% worth it, 10 out of 10 would do it again. I don't see how I'll ever go back to a N/A V8 car. This is honestly too much fun. The power, the feeling, the sound will get you every time. If you like your N/A car, you'll like it even more boosted.

Run on Vortech's own Mustang chassis dyno (lower numbers than a comparable Dynojet), the stock Bullitt produced 239 hp and 243 lb-ft of torque. Equipped with the standard Vortech kit, the peak power numbers jumped to 329 hp and 309 lb-ft of torque.

The power I get out of this supercharger is just amazing... You can spin your tires going 70 mph if you hit boost going that fast its amazing.
