1 Mile of Full Throttle

[RagmopInKona]

Lmao, a stock coyote can easily do a 1-mile event.

Not at red line it can't.

Ive done a full mile or so starting at 60 ending at 194 mph. Boosted at 800 rwhp, running e50. No problems caused by that for me. More efficient blower than roush, and on ethanol and also great weather though. Only took about 15 seconds. didnt want to do more.

What do you mean “not at redline”? Like surviving the time it would take to do a mile with the rpm pinned at redline? Or do you mean revving the car to redline while doing a standing mile?

A flying mile where you are already at top gear and at redline throttle matted at start of measurement. Any engine can do a standing start mile.

i dont think that exists

While generally correct, the GT500 pistons are far superior and ringland design specifically. Coyote pistons/tight ring gaps are the problem in boosted high HP setups on gasoline.

I had 2 ringland failures. 2 OEM Gen 2 short blocks. Zero detonation. 17° of spark on race gas both times. Both happened during the same exact situation. Long 3rd gear 60-130 pulls.

A non forced induction Coyote definitely can go WOT for MILES like others mentioned.

that's shitty. 17 degrees is 93 territory with 10psi or less typically. Wonder what your dew point was around those failures.

I hate to be that guy, but yes it can. A stock engine can take hilarious amounts of abuse. Stock redline is pretty conservative, people raise it in tunes all the time.

1 mile at the limiter wouldn't even phase the car.

The Coyote is strong, but FI causes a lot more heat in the combustion chamber, and I have also heard about ring failures under extended WOT with force induced Coyotes.

Todays oem engines run tight clearances for emissions and mpg. As things get hot they tighten even more till the rod overheats and gets tossed out the engine case. Long high rpm is hell on a stock engine not built for it.

It would be completely fine for a standing or flying mile.

I know a dude that's run his stock 'Yote in the Texas mile multiple times, not a problem.

How much boost?

 

[Prodigal]

in for the results. i do not believe there would be any issues.

let 'er rip 'tater chip!

If a stock engine couldnt handle 1 mile of redline, there would be a billion warranty claims, as many owners literally do just this, or driving around redlining it everyday of its life. im 10000% positive, these engines can handle redline for a long ass time under load no issue.

its when you start adding hp add ons that causes issues. as delivered in oem config, its handled to tolerate that hp pretty well. in general, you dont see people having issues until they start modding, yes some do break, but its very very few and far between, and its from a faulty party from get usually.

How much boost?

Then? 12-13psi. Between 712whp the first time and 760whp the second time.

 

[WildHorse]

Unrelated, but what would a similar pull do on a completely stock coyote? Any weak points?

I did, 8 miles @ WOT. Everything was fine. Car felt very planted through the whole 2min 35 sec run.

Did you take a trip to Bonneville?
