Rear Wheel HP

[recurve69]

Without getting into that entire Octane issue. How much HP could one expect to have using 91 octane at the rear wheels?

Stock IIRC around 370ish.

I am screenshotting this from C&D mag back in 2019- took 4 bone stock OEM vehicles & ran em on dyno w/ 87 vs 93 octane, one of which was an F150 w/ the same 3.5 HO in our Raptors- not only did the Ford pick up the most hp/tq, it SIGNIFICANTLY improved the performance erasing 6/10ths from 0-60 (huge) & 1/2 a second through the quarter- take a look @ the 0-100!!!

YES running 93 octane is better overall every way more power runs smoother & gets better mpg!

I’ll note - the actual dyno #s are somewhat irrelevant as it’s not a Raptor on 35”s w/ 4.10s….but I think stock raptors dyno 340-370whp & 93 octane tuned raptors 420-450
