[@JuanGonzalez-mi9uj]

Hey chief and Jackie i totally agree the pop was because you killed it while still in full throttle which would give out a bang everytime you do that. Also great job on breaking it down so everyone can understand as always keep up the awesome work guys let's go 💪💯

[@kadenfox7558]

Love watching these types of videos. Feels like a constant behind the scenes, feels a lot more personal. Good on you chief for looking into what happened and being open to put it out there for us to see. Shows were all human and stuff happens. What you said makes a lot of sense going from movement and then just coming to a halt definitely could cause that bang. Seems like more racing and less problems heading your way!

[@walthansmann]

That was an excellent analysis, Chief. The data logger seems to show it. You need to have a discussion with the driver to have him get his stuff together in the shutdown! 🙂

[@DavidKing-vb9ux]

You might want to check the turbos they may not be very happy with uncontrolled rapid expansion of gases. I’d say you’re spot on, dude.

[@mickwhelan6938]

Your onto it I think same happens with our mini bobcat at work when throttle is open and ignition is shut off goes bang everytime scares shit out of me everytime also love your vids keep em coming

It Definitely over Fueled Probably the way you shut it off so I definitely agree with you. I love your honesty. Also I've seen many new races lineup with the rear tires. I personally have never done that but I have seen it. I know that was the last video keep up the good work Pontiac man since1981 still own that same 74 GTO, have a great day. Be safe.

👍✌️ Chief I'll tell you exactly what that was a soldier.. not enough dynamite, black powder, plastic explosive...... Soldier if there was enough in there it would have went boom instead of just bang... and that would make for a really hell of a video Don't you think, LOL LOL..✌️👍

[@jondoe4667]

Me too. A couple years ago I did the head gaskets in my Silverado and when it was all done and buttoned up it still wanted to run hot. I was so mad that I just knew I did everything right, and didn't know what was wrong this time I parked it and didn't even open the hood again for like 4 days. Then when I was cleaning up old parts I found the brand new thermostat that I apparently never installed because I accidentally stuck the old one back in it. And in my bones I just knew that the radiator, water pump, t_stat, hoses, head gaskets...... Everything was new and there's no way this could be happening. 😂🤬

[@79tazman]

Yeah that explains it and that's why it popped out both sides because you killed power while still feeding it fuel. I makes sense I was thinking you hit boost cut or something at first anyway glad it's all good and you don't have to replace any pistons or anything.

I know a guy 30+ years ago that had his old Ford trucks distributor wired to an on / off switch..he would be driving and see people out in the road and he would flick the switch off to on and when the points made contact with voltage "BOOM'' just like somebody fired a shotgun..it was crazy !

[@turbotonye-4124]

Hey all in all id be happy with that. It just goes to show how much drivers rely on their habits while behind the wheel. Changing tire size missed everything up. Lol. Thank god for data! Not only helps with tuning but also helps with the localisation of problems

[@BenjySparky]

Chief, y'all rock! I think you hit it exactly on the head with what you're saying. Back 25 years or so ago, I was driving down the road, turning off the ignition with my foot to the floor to get it to backfire, and it blowed the catalytic converter in half😂. I'm glad you figured it out, though. Peace

[@mikesautomaintenance5780]

💯 right on what u think happened the log don't lie pre ignition back fire was still dumping fuel in as your holding it to the floor when u killed the power

[@bendaves77]

That makes sense since in the video you're still hammering on the throttle and then boom followed by slowing down.. I'm no tuner but it makes sense.. I was hoping you were going to have to call Butler and get Mr Crow one of their big block Pontiac engines

I think you’re right, but if you’re listening to me you’re already in trouble!

With the engine off there is no safety neutral if your TH400 has that? You probably have an aluminum direct drum but it is over speeding and subject to failure/ explosion. I understand you are trying to pick the less of the evils during shutdown. Love the tech and the channel in general!

[@Oldschooljake1979]

Hahaha, that reminds me of my uncle Buzz, had an old mercury bobcat, he'd rev it up, turn the ingniton off, and then back on and,POOOOOOWWWW!!! it would back fire big time. Until he blew the exhaust pipe to pieces one day, and it broke the passenger side window out. LMAO!!!'

[@mr.stonerUDX714]

I say you shut the switch off too soon caused a back fire

[@edwardsjohnpaul]

Stick a camera on yourself in the car, for future runs? That'll show what you're doing, and see if it jives with the data. In the long run, could you decouple the data logger from the engine ignition, so that you could shut off the ignition yet still have "eyes" on what's going on w/the motor? That'd be useful in so many ways, but may be tougher to implement in the short term.

we usually do, the camera battery died

[@bubbyscoresagain1720]

Post ignition detonation, trying to burn excess fuel after ignition kill.

[@Reignin1]

🙋‍♂️... I think your theory is correct Sir. It make scents that whatever unspent fuel injected after the ignition was cut has been ignited by the high heat of the exhaust pipes.

[@stevenbelue5496]

I would think at that high an rpm, from one revolution till the next would be milliseconds and if ign was cut between those revolutions, between two exhaust valve opening events and I envision the first exhaust valve opening event that ignited in the cylinder, that theres still fire or fuel burning as that exhaust charge exits past the valve and enters the pipe so the next exhaust opening event that had ign cut and didnt fire, as soon as that exhaust valve opens its igniting right then and considering valve overlap some of that pressure wave is going back into the intake tract. Maybe not enough for a burst panel or maybe the lobe seperation on a turbo cam helps prevent that somewhat. But seems like with a lot of overlap that could cause some damage.
