Was hanging out in the driveway tonight, goofing off. Did a few rev's, maybe up to 3500RPM, and then It sounded like the Whipple belt shredded and the engine stalled. Come to find out, the belt is fine. Car will not start. Throws a wrench on the dash and nGauge shows a P0339 code. Clear it and it comes back. Sounds like no compression. Any thoughts? Was going to pull the valve covers tomorrow and make sure the the cams are turning with the crank. Also going to check the plugs. Oil and coolant look good.

Oh man, that doesn't sound good. Hope it's nothing serious.

P0339 Crankshaft Position Sensor - could be your oil pump gears/camshaft sprocket. The stock ones like to snap with boost - yours still stock?

I'm not a pro so.... hoping for you that it's just a loose wire, bad sensor, weak signal to the sensor. I believe the code primarily represents a circuit issue with the CKP so I'd be thinking electrical issues first.

Crank shaft position sensor issue https://www.engine-codes.com/p0339_ford.html

I would check the 4 connections to the cranks shaft cam sensors.

1. Unclip and clip them, then check all the wiring the best you can make sure nothing is out of place or damaged.
2. Check your battery connections make sure they are good tight and clean.
3. Pop the cover off your air box and look at the end of your filter there are 2 ground there that have know to come loose from the solder mainly due to the filter hitting them. This will cause all kinds of problems. You may need to remove filter to check.
4. Check your battery and charging system make sure it's not weak.

Did you do any work to the car recently before this happened.

Sounds like some wires got caught in the awesomeness and couldn't handle it. Hope that's all it is!

The sound you heard was probably the oil pump gears eating themselves. I highly doubt its just a loose wire. That sound was a huge clue that something mechanical failed.

It's well documented that stock oil pump gears fail on supercharged coyotes.

It sucks, but you can upgrade to billet gears. Good luck.

But, on the other hand... I'm not sure what sound you heard that sounds like the supercharger belt shredding?

And the fact that you didnt get a low oil pressure light is good news...check the crank position sensor.

All is still stock. Not ruling out the OPG, but never got an oil light or code, like when the OPG shattered on my '14 and it would still start. As for the Crankshaft sprocket, when I popped the oil fill cap, a can see the cam tuning over with the motor.

That sound better with cams moving. But the sound it made sounds bad. Hoping it's ok. Keep looking boss. But opg your oil light comes right after it fails.

Well, I was thinking the flywheel or ring failed, but that theory went out the door when the engine cranks, courtesy of the starter.

The crank pull spins, eliminating a failed crank.

Everything on the belt drive spins freely.

Then I thought, maybe the gears in the back of the Whipple, but I looks like the rotors are spinning when the engine turns over...... watch your fingers when your holding the massive TB open and the key goes on!

Remove the oil cap and the cams turn with the engine.

Car has 15k on it and has been Whipple'd since 3k miles. Has ran strong like bull, with not one hiccup until last night.

Not that it matters! But Lund tuned---- Just to answer someone else's question.

Pulled the drive side plugs, all plugs look good, one piston looks like it has two half moon stamps where the carbon is missing. Have not done a compression check yet.

( Note ) I had an OPG fail in my 2014, while driving in traffic at 10%-15% throttle. In that case, the oil light came on instantly! But would NOT cause the engine not to start, not did that throw a P0339

Just saying mate - hope I'm wrong but usually when you get a pop like that and then engine is no worky this means OPG/CS is shot.

The fact the valves hit the piston as you suspect means the cam sprocket is most likely broken. This would not cause any problems with
oil pressure but it will throw a crank sensor code as the cams sensors are in different position now.

Please keep us updated.
