Does your car have billet oil pump gears? If not or you don't know I would sure do some research on OPG failure in modded 5.0 coyote motors.
If your car really does have 705 rwhp, if it's a manual with 15% parasitic driveline loss that is about 810hp at the crank. I would definitely do some research on the life expectancy of 5.0 coyote motors when they are pushed to those levels. Most do not survive at that power level long. The rods are too weak.
Does your car have a catch can?
Stock head bolts?
No boost gauge?
Just FYI there were some changes made to the 13-14 Coyote to help prevent the notorious #8 cylinder failure issue that was so prevalent on the 11-12 cars.
Not knowing who tuned the car would scare the heck out of me.
IMO I would run M1 0w40, and call it a day.
The dealership which I acquired this from gave me a bit of background of the gentleman who had it prior (lets just say it put confidence in my purchase, though they had to contact him to answer some questions I had about the car, as he keeps his contact info private and is very busy) and seeing the dealership printed sticker including the supercharger and other mods that were done by the Ford dealer prior to him even taking delivery of it new....it all holds water. It was apparently tuned by a performance shop a few states away. Upon looking over the car even more, I can tell this literally was his car and coffee cruiser that he took to shows and drove sparingly.
I'm no mechanic, nor generally work on my own vehicles, but I can generally tell from driving and racing experience if something is amiss. My background of driving experience and ownership falls to American Muscle Cars, as well as German and Italian performance cars, naturally aspirated, turbo, supercharged, & nitrous oxide equipped. My take is the tune is good. It's the smoothest Muscle Car I've personally driven and owned.
The car is said to have made 705 hp at the engine, so I am within safe parameters due to a very likely on point tune, given this mans history. Yes, it was a bit unsettling at first but as I gathered more information prior to pulling the trigger, I ended up jumping at the opportunity. I was blessed to get this car for a very very low price considering I purchased it at a large dealership, with the low miles, mods and stellar condition it is in. It also has some minor suspension component mods, and some other pricey add ons which I got all for the low price of about $1,500- above fair market value for a car without all this done. I've access to the Worlds largest auto auction here in PA, so wholesale was an option, but this would have brought more than I paid at a highline sale.
Stock Rods? Probably.
Catch Can - Yes, it came with a JLT Performance one. Plus I just ordered the updated 3.0 version yesterday too, as the old one angled over the paint matched valve covers; I prefer the new location of the updated one as the original owner got the best available at the time, straight up and down is best anyhow in my opinion.
As for oil pump gears, I can't say, however the way I do maintenance and preventative stuff, it will get them very shortly if it doesn't. This car was built right, and I was blown away at the bargain. It fit the order nicely for what I desired to get it for.
Regarding the head bolts, again, no idea, however Ford did design this kit to be put on an otherwise stock car. It has a few minor mods and the tune which pushed it up to the 705 hp at the engine. Drives like stock but sounds better. Blows away all but the most expensive factory cars, or the most hyper worked street cars, so I am not complaining.
Depending on the oil analysis results I'll consider going to the 5W-30, MAYBE 40 weight. But with an oil cooler first, with the 5W-20 and future gauge addition to SEE what is actually going on....that's the best plan of action at this point and moving ahead.
Never had I thought there would be a HUGE forum for oil specific things until I happened on this nice little site a couple weeks ago or so. Glad I did, it's been a good source to draw from.
Cheers!
