I first want to make clear before starting or opening this discussion. This is NOT a "Finger Pointing" "Blame Game" or "BASH" thread! I will ask for your post to be deleted if I feel its out of content or demeaning to that nature. I chose the verbiage of the title for, "Hook, Line & Sinker" method to attract the most eyes, experience, knowledgeable feedback from those who may have experienced such a problem or if you are also a experienced Tuner/Builder/Racer/Fabricator of nature. Now that this is out of the way....

My car:

2012 Mustang GT 5.0 Coyote 6 speed, LSD, 3.73
FULL "BOLT-ON BUILD!" ... Boss 302 Manifold, BBK TB, JBA Titanium Headers, JBA O/R X pipe (no cats), MAGNAFLOW "Street" Exhaust, JLT CF CAI, Moroso Radiator Tank, LU47's injectors, E85 Tuned via AED/Shaun, Suspension, Wheels/Tires...etc

This past Saturday night I was at Showtime Drag Strip running the 1/8mi getting some seat time working on my 60ft. (as I have been for several weeks since complete...) Approx 4th run I take off (like a bat outta hell! I felt it like no other run!!! ...as they do before they GO!) Top of 2nd gear to 3rd as I remember, they car gave out. Not very loud of a noise but loss of power and EXTREME! cloud of smoke from the exhaust, engine bay and filling the entire interior of the car as the car coasted under momentum across the line engine still on running at idle. It was all to fast for me to stop earlier and it was all so confusing and shocking but the time I pulled myself together I was passing the finish line to exit off to the right onto the grass just as I passed the 1 st exit return road. For maybe 2 seconds as I came to a safe stop, that is when I noticed the car was still under its own power but NOT running smooth. The engine was NOT noisy, clanking or banging around. The sound as best as I can describe it was as if 1 plug was pulled from each side...

After pulling the car off to a safe open area, friends and I looked everything over to see if there was any true obvious signs to what happen and how bad it was. Oil and Radiator fluid seem to be slashed everywhere but most noticeable it was oozing out of the intake through the JLT filter onto the chassis metal flat surface located just under the filter and filled that entire area with the infamous "Chocolate Milky" soot. After seeing that, I removed the entire CAI assemble down to the TB and it was still pouring out slowly from the TB lip from the intake. I then took a socket/racket to the crank bolt, engine seemed to turn fine with no noise, locking or anything abnormal to mention. Going back to the TB, I slightly opened the shutter/butterfly and there was a small metal shaving found...That was my night. I went out to hang out and watch the remaining races trying to just have a good time. There was nothing else I could do that late under the circumstances.

The car was then storaged in a locked shop of a friend who offered the shelter since he was off from work with family from out of town for 1 week. I returned Thurs. to pick the car up and trailer it directly to Colin @ RACING INTEGRATION (local well known SVTP Member). Upon arrival, Colin wasted no time since he also was o perplexed to why this "ALL MOTOR E85" car failed and failed in this nature. Colin pulled the covers, coil packs then the plugs. Starting from 5,6,7,8 (Driver side) and finding no issues he continued to the passenger side in 4,3,2,1 sequence finding the big "WHOA FACTOR" in the very last cylinder he checked, #1.

Besides everything I described with the best of my abilities and stating that only! to what happen with up to date to what I know and found out, maybe I can hear what someone has experienced or someone may know any factor that could have led up to this point. REMINDER: This pic shown is all we know as of yet. Colin will start tear down sometime this coming week Tues/Weds to find out and clues or the extent of the damage. At that point, I will also return to the thread keeping it updated of my findings. In conclusion, If I am not able to get a answer or assistance from this thread, someone else will definitely get some sort or extent of help as future/present reference.

*** Please feel free to chime in with your questions, comments of concerns or experience. Please NO BS! or BASHING! Just open discussion if it can possibly lead to solving, pin pointing or theoretically speaking help. Since it can be 1 of many failed areas even down to 1 single part. *** AED feel free to chime in also. :coolman: Thanks to all...

You already know how I feel about the subject.


Assuming no other cylinder is messed up. I say cyl 1 injector malfunctioned. Deff have them flow tested ASAP. Check ecu for any burns also. The coolant is weird, maybe it lifted the head under extreme detonation.

If it was a tune issue, I'm sure you would have seen this happen long ago and other cylinders would show similar signs. I also don't see Shaun's tune being so out of the ball park that this could happen, even more so because this is e85 we are talking about.....


My e85 car has 7k miles AED tuned.

Long time no talk!! PM me if you plan on going out anytime soon.
I moved back up to NC last month for work and the GT is at the dealer now getting a new tranny and the rear end rebuilt under warranty. I'll be back down for FL2K14. I'll make sure to get in touch with you guys.

If the #1 injector stopped firing, it wouldn't break a piston. It would run funny and be very noticeable, but it wouldn't shatter a piston.

No fuel: no fire


On the other hand, if the injector stuck open, it could hydrolock that cylinder and break something with a quickness. Post up when you get the injectors tested.

Not sure if the piston is shattered. It sure does have a hole hole burned through it from what I hear, directly user the plug, probably also shattered too though from detonation. Hydrolocked probably would have thrown a rod, maybe.

Clogged injector and or failing injector.....possibly. This car isn't his daily, so maybe the e85 gunked up during the time it was sitting and injector had some issues. Just an out there in left field thought.

Also thought maybe the e85 was not e85, but I'm sure that damage would also be present in other cylinders.

Interesting... So, these engines don't run "LEAN" and cause damage as others have and under my understanding always has/can. Still very interested how u put it. Thanks Justin

Well, it was tune or component failure. Check the injector, fuel filter and fuel pump. How close is a 5.0 stock fuel pump and E85 to max?

No, he's saying. If there is not fuel, it won't run lean because there is nothing to ignite. Which a completely stuck injector, most likely would not let any fuel past. Therefor the plug would just be firing and not igniting anything.

True...Not my daily but I do drive it every couple days keeping things fresh, lubed and loose from use. I avg 1x a week couple miles and often starting Fri-Sat. I somewhat stop driving my 06 Accord when Friday rolls around. Definitely more to come when tear down begins. Until then, this is all I have.

I've always hopped back to my pump gas tune every so often to "lube" things up. Maybe that's why I don't have te "e85 pump failure" some experience, who knows that's a mystery in itself.
