Wow thanks for all that. What’s your setup? lol.Why do car enthusiasts continually do this?
It's a form of confirmation bias. It's like asking...."What's the heaviest person who's ever successfully bungee jumped on this setup?"
You're going to get a shotgun spectrum of answers, but as car guys we should be OVERENGINEERING and UNDERUTILIZING (like the OEM's who are responsible for warranty claims do).
The problem with most of these answers is that many/most of them are under IDEAL conditions. The car is sitting on the rollers in a shop, with good quality fuel, the motor isn't being lugged, uphill on a hot day, etc.
The example I always use is....how many people can you safely fit in a 12' Aluminum flat bottom boat. Sitting right next to the dock, you could probably fit like a dozen people in that boat (without it swamping). You might even be able put put around on the water at very slow speed on a totally calm day.
Can you take that boat with 12 people in it out on windy day with 3' chop? I wouldn't, unless you like to swim.
If we're asking "how much power on stock blah blah blah" for the purposes of seeing max value and then backing off for a safety factor, I agree. But these "rules" and arbitrary limits are just that, it's guys and tuners and shops making power on a motor that's max'd out any sort of responsible safety factor or ability to accommodate for less than ideal conditions.
So, can you run 700 rwtq on stock axles? Sure, until it breaks.
You're probably going to get answers approaching or exceeding triple digits on the stock block and bottom end. Would Ford warranty 4 digits on that setup? Nope, cause they have to pay for carnage and failure and warranty claims.
My advice is to pick the level you want to be at and OVER shoot. If you want a 1000 rwhp setup, build the motor for 1500 hp.
You can have it fast, cheap or reliable. Pick any two.
You can run more on e85. And really it comes down to the tune and timing. 10psi is a “blanket” rule For a lot of email tuners maybe where they don’t have a ton of time to stick with your car and it’s just gonna be “safe”.18psi is too much for stock engine for longevity imo, 10psi will get you close to 800hp on e85, if you want to run that much, be prepared to do an engine.
I am very familiar, i have been a racer for 22 years, and specialized in the coyote for 11, and we are the largest power adder dealer for coyotes out there.You can run more on e85.
