901 Horsepower Scat Pack Challenger

Scat Pack if ordered with larger engine is a 6.4 like my SRT. The hell cat is different 6.2. Looks like they are strapping one to the 6.4. The 40,000 appears to be for the car alone from what I took from the link. In order to boost a 6.4 you have to replace the pistons at a minimum to get any serious power. That is the weakness of them. We can only boost to about 6lbs stock. Major work has to go into the block to boost it higher.
