    786 at the wheels? On 93 octane pump gas. Happy dyno, hero run and maybe octane booster.

    The fact remains, the octane limit of pump gas on 11:1 compression in the coyote simply can't support that amount of power. That's automotive engineering fact (I should add that based on the mods he has listed in the video). You can turn the boost up but would have to compensate with timing and the net result being zero. Any body claiming those figures and worse believes in them is absolutely kidding themselves but whatever helps people sleep at night.

    Too many people out there claiming false numbers because the dyno said so. A dyno can read whatever you want it to. Those with any understanding of the coyote engine with its compression and boost and timing and their relation and dependancy on Octane will tell you those figures aren't real.

    Anyway... Good discussion.

    The 15% comes from EHP vs Chassis. Europe would have to read 15% higher based on what you say regarding listing HP at the engine.

    Therefore 780hp at the crank would be make it around 660 at the wheels accounting for the 15% which is pretty much the limit of pump gas in the real world.

    Good discussion. Every tuner I seem to speak to have the same message but you tubers and people on the forums saying different things... I know who I believe.

    Thanks for the reply, food for thought.

    I'm coming round to the "fact" that I "need" a S/C, but I've got the MY19 GT with gen 3 Coyote & I've no idea how far I can take it on the stock lower end, not wanting to go sleaved & forged straight away.
    Cheers.

    Im pretty much at the limit with mine, 815hp at the flywheel and pushing 700 at the wheels, but thats it. Anything more and I would be in a world of hurt with things breaking.

    Regular fuel 98 octane, larger injectors, fuel rail, pulley, fuel pump and some other bits.

    Sorry I should have clarified. 15% difference is when numbers are converted to be like for like. So, whp vs. whp or bhp vs. bhp.

    Great build bud. Out of interest how did you get the 18+ Active Exhaust to work on your 16?
