Watch: How to Make a Camaro Exorcist in 5 Easy Steps

Hennessey Performance is among the best-known tuning companies in America because of its ease with quadruple-digit horsepower figures. Here, they let us in on exactly what goes on when you give them your Camaro.

In just a few steps, they can turn your pretty powerful ZL1 into a ridiculously powerful Demon-beater.

The first thing they do is dyno the car to make sure it’s in good enough condition to be modified.

Next, they remove the supercharger, the front drive accessories, the cylinder heads, and the camshaft.

They then add new headers and a new 2.9-liter supercharger for more power.

They then put it back on the dyno with to calibrate it, messing with the air/fuel ratio and the ignition timing until they’re right.

Finally, they test it on their track to make sure it’s ready to go back to the customer.

And that’s it. Sounds pretty simple, doesn’t it?
