It will dyno about 395whp stock, multiply that by 1.18 to get you 466hp, the REAL stock hp. Adding another 125whp is entirely feasible with the JB4, a turbo back exhaust, and some good gas. That will then net you about 520whp, or 613hp. It's fairly simple when u just do the math.
Even if u guys want to low ball the power potential, say, +75whp with the mods listed above, that's still 470whp, or 554hp.
