I think there will be similar gains, if not pretty close. If you think about it, the FA20 made 205hp, or 102.5hp/liter. This falls in line with the ~170-175whp they tend to put down, assuming a ~15% drivetrain loss. And it appears the FA24 is making ~250hp, or just about 104hp/liter. So the percentage increase in power is very close to the percentage increase in displacement. That would tell me that similar, or at least pretty close, gains could be had with bolt ons, tunes and e85. Some people managed 30-40whp gains with FBO and e85, I expect it will be similar. Once tuning is unlocked I have no doubt we will see over 250whp, NA on e85.
