"The engine run parameters were recorded to aid development of their new 4.2L "Hellcat" blower kit. This will allow naturally aspirated 392 owners to step up to 901 hp for around $7,000. We're getting ahead of ourselves here, but the numbers pencil out like this: Buy the 392 Scat Pack Challenger for $39K, add the 4.2L Kenne Bell blower kit for $7K, and move into the fast lane for around $46K and change, all in. It's a great alternative for those who can't pony up for the Hellcat's $60K right off the bat."
901 hp....WOW!!!
