[QUOTE="tt335ci03cobra, post: 12700905, member: 68944"] Theyre robust actually. 650whp for a coyote thats well tuned is "safe." They can easily be a time bomb if tuned incorrectly, or setup poorly or just unlucky but all three are low chance scenarios with a studied owner. If you keep up on checking fluids/fuel/spark as regular maintenance, have it tuned reputable (guesstimating with a game not program need not apply here) they'll be fine. As with longevity in general, the owner can decide how long it should likely last. If its rallied to an 100 on every road, cold start boosting, not getting fresh clean fluids often, not correctly gapped plugs or an occasional a/f checkup/doesn't have an a/f gauge I the car, then tick tick boom is likely just like a fully forged $15,000 motor can be grenaded in weeks with a similar owner. A lot of people are making anywhere from 600-9xxwhp on factory coyote internals with mixed use. It's not going to last forever but an honest 5,000 miles (9xx) and much more can be had out of them even at those power levels with track outings. Some have broke day one, most haven't but will eventually and some will never see the track or break, or are garage baby's that see 500-1500 a year (a lot like my car hahaha). The vvt-ti in their heads allows the tune to be very very boost friendly. You can push and pull timing pretty much as much as you'd like and make detonation almost a non issue. Factory compression is high, but you can make static compression 7/1 by pulling it all out from 5k rpms on (not the most powerful but doable) They are high compression factory, but longblock for longblock, a coyote will live at 650whp much longer than just about any other high compression na motor will at any price level, let alone a $30-$40k pony car. They are much more robust than ls7's for comparison at about only 60% of the displacement. In essence, even though neither the coyote nor the na 4.6 na 5.4 4v's, or any ls1/2/3/6/7's aren't factory boost mills, are all "high compression" na mills, and weigh within 100-150lbs of eachother roughly, the tiny 5.0 coyote supersedes them all if boost is a wanted addition, by leaps and bounds. A booster coyote is more robust than light fordged/budget friendlu piston/rod ls's on average. It's not a rule but where 800whp is getting dangerous on a mild forge piston build ls6, a coyote is ready to go 12 rounds at that level assuming proper setup and care. They aren't made of glass at that power level but they aren't diamond either. A forged piston stock et al coyote will last a good long while even at 900whp, maybe 5-10k miles with modest to moderate track outings. 900+whp coyote's won't live long at all on that power level if they're beaten on all the time but if you have twins or a big single, cruise around on 4-6psi making 600-700whp, not driving like a hooligan but getting on it often enough to only average say 14-17mpg, some on ramp romps, a few canyon straight away pulls, some freeway fun here and there, etc (just not Indianapolis500 on every red light/straight road/reckless driving everywhere), then bump the boost upto 10-15psi, run 116, have nice safe well managed dyno tunes, check your fluids, spark, fuel system before hitting the track, run a few 9 and even high 8 passes (factory (6r80's?) 6spd auto trannys with converters and shift tunes have gone this fast, im not talking th400 autos) on slicks/et any setup, then check a quick run through after passes, bump boost down drive it smooth home, maybe romp on the on ramps a little-that kind of life will not blow up a coyote very quick. A mature driver shouldn't see a fail near as often. The ones blowing up at 650whp are either driven very hard, not tuned all that spot on/setup completely properly, or in small instances, are simply the unlucky ducklings that weren't as strong as most do to quality of manufacturing but this is rare to say the least. It also depends on the type of boost. If you're making 650whp on well tuned/setup turbos @ 4-5psi, you are very safe. 5-6psi on a centri, it's still safe but the extra boost isn't as friendly obviously nor is parasitic drag. 5.5-7psi on a roots/lyshom/pd- safest is pd, then lyshom then roots for the same reasons as the Centri's plus extra heat and more drag but still safe enough that a responsible owner can and will see 20k miles and more very easily. These motors are so new that their life expectancy is hard to gauge, but compression tests are showing a year of life at 650+whp in any combo isn't that bad at all unless its driven very hard. If your hitting 150 on every drive to work, ya it'll blow up quick but that driver will lose their license quicker any ways and go to jail probably before it lets go unless they live in Germany haha.
