Likely a decent amount. The recurring theme I was hearing from tuners is that the HPFP is quite strong. It runs 350 Bar or around 5000 PSI. Even then, supplementing fuel shouldn't be difficult with port injectors for meth and/or fuel.Fat powerband. Wonder how much capacity is left in the stock fuel system.
Tough statement to make when it can't be applied throughout the whole RPM range though. Torque is definitely not greater than HP over 5252 RPM and in a drag race it looks like each upshift brings RPM back to ~5100, so the meatier part of that TQ band isn't in play but for a fleeting glimpse in 1st gear. My vote is for the higher HP being faster; all else being equal.The car with the dyno previous to that vid will be faster. Torque > HP
