Great breakdown of the whole unfortunate event. Love how you guys just take it on the chin, smile and get on with getting it sorted. Good luck on the next dyno session and when you hit the track. She's going to be a beast.
12:34 For your viewers, EGT's can be deceitful, because a slightly lean cylinder will run hotter (than perfection) a very lean cylinder will run colder due to lack of fuel to create the heat.
So I think it’s worth pointing out, it’s interesting how there was that much of a Backfire Explosion, and yet it never hurt the motor. Working with serious Meth and Nitrous engines, I have learned in last 2 hrs, if the fuel isn’t there, it can’t torch or hurt the engine. As it shows, it leans wayyyy out, and ignition happens, boom. In cyl was lean as 7.85:1 from what I saw… this proves the thought process. Separate from the actual backfire, which happened from inj cutting off, creating hotter air, and timing was too advanced for that type of condition. Obv it’s fine when fueled, but with a lot less fueling, it gets pissed off….i think it’s important to explain this to everyone, as I was always told, it went lean and popped…..well kinda only sorta…….the motor is timed for optimal conditions(or at least that days cond), so when it got wayy lean, it became over timed. I have learned this the hard way recently. I run a custom table, that watches EGTS, if EGTS get more than ~200* and TPS is still 100%, it will start to pull timing. I have it gradual to start, and yank a bunch within .5sec. It has saved a few Nitrous engines now, and sum Meth engines too! This safety is really combo specific, and can be a wider gap around 300*, but essentially it has helped greatly. You can get really particular, and get it to run a lil more rich, and rely on the safety, once you have a good understanding of what that engine is doing. Just as John has found out, anytime I’m running a Meth motor real rich for cooling, and sum goes wrong, even a backfire, sum gets hurt. Mostly torching of heads, or breaking lands. I have torched a top ring cple times as well. This has NEVER happened when it’s close to stoich, (5.5ish). Not finding anything wrong with the tune up in your case, just saw a great chance to explain this. It was really hard to wrap my head around at first, as we’ve always been taught, lean hurts engines. But really it’s the timing at that lean of a AFR that really hurts anything. Another great example is how lean some engines run down the hwy nowadays. Manufacturers can get away with Almost 17:1 under light loads, and very little timing. I know it’s a rant, but I really try to explain this to ppl as often as possible. REM, it’s all about cyl pressure, so when it goes leaner, it creating greater cyl pressures, earlier, which means the timing is too advanced as the pressure builds sooner and faster. REM FFFS. (Flame Front Fxcks) hahaha.
@@freedomfox8183 well yes in that one situation it wouldn’t do anything . But i must have missed where in this video they said the mechanical pump failed . Usually if a pump fails car just shuts off so, maybe they should ditch the 2 stage pump .
alot of nitrous cars with tunnel rams the top plate is held down with Delrin studs for that same reason . if there is a back fire it just pops the plate instead of trashing intake valves and bending throttle blades
If you have EGTs per cylinder, you can make your ECU throw an alert, and if it's fully EFI you can make it go into emergency mode and not blow your engine or blower! FT ECU itself does that pretty well!
Pretty sure fueltech can set up any engine parameter or combination of them for safety's. O2 or fuel flow safety could of maybe saved it. But I Don t think a lot of these guys take advantage of the safety's because they can also cause you to lose a race due to a sensor malfunction I suppose.
So it went lean and Kaboom! That will do it that's what I thought happen because you were not even pushing the engine it was only half of it's full potential I did not know it was hybred I figured it was full EFI.
@@bigboreracing356in a race crunch situation the tools and parts to put it back together would’ve already been on the table before your carburetored car you spent a 1/3 of that on would’ve been coming back down the return road

NOT THEIR MONEY
My thought was an intake valve dropped or valve keeper failure. Good information. Thank you.
Yall having all the right things may have saved someone’s life!
Fuel - "I don't wanna go in the cylinder, I'm gunna burn here in the manifold"
🤣🤣🤣

And today you learned why burst panels are supposed to be there.
It does have yield bolts in it, that failed.
they showed us the burst panels blown out go back to the beginning the burst panel was there lol then it left the chat
I honestly think that's the first time I've seen a burst panel go. Normally I've just seen the bolts break.
Burst panels are for the small blower sneezes, a bigger back fire will just about always blow the blower off.
Ya I’m surprised the burst panels burst when it knocked the blower off . Usually it’s one or the other .

Good explanation sir!
Blows me away every time I hear a guy say he has no idea what size the engine in their car is...
The difference with full efi is both sets of injectors can start increasing fuel when it starts
Going lean .
100% right
Injectors don't do much when the fuel pump fails
@@freedomfox8183 well yes in that one situation it wouldn’t do anything . But i must have missed where in this video they said the mechanical pump failed . Usually if a pump fails car just shuts off so, maybe they should ditch the 2 stage pump .
Sometimes I love john and sometimes I wished he'd shut up and let others talk. And also like the last video welcome to blower life.
Steve Morris has an intake that takes three sets of injectors. One for doing the daily drive and the other two for racing
alot of nitrous cars with tunnel rams the top plate is held down with Delrin studs for that same reason . if there is a back fire it just pops the plate instead of trashing intake valves and bending throttle blades
If you have EGTs per cylinder, you can make your ECU throw an alert, and if it's fully EFI you can make it go into emergency mode and not blow your engine or blower! FT ECU itself does that pretty well!
The ecu doesn't know there is a mechanical failure until after the failure.
Can't you set a safety to read the O2 sensor, if it reads too lean then it would shut it down? If not it should. Nice job on the wiring.
Pretty sure fueltech can set up any engine parameter or combination of them for safety's. O2 or fuel flow safety could of maybe saved it. But I Don t think a lot of these guys take advantage of the safety's because they can also cause you to lose a race due to a sensor malfunction I suppose.
In this type of situation by the time the 02 sensor sees it the blower has already tested out the straps
Its crazy when you see them have a failure like that and make next round.....
Could you use that status event (11:30 in the video) as a safety to shut down the engine?
We’re going to add some safeties but a lot of times it can’t catch it fast enough. However this time I think it had time to
Either the threads were crap or the bolts weren't long enough to hold a break.
I agree I think the threads were already weak
Can you double the burst panel area? Any lean sneeze on those blowers hurts stuff.
The entire blower is a burst panel they use weak/breakaway bolts for a reason
Manton rockers are top of the line I know Steve morris SMX engines run Manton rockers and pushrods
Falou tudo! Muitos motores quebram por causa de peças de 25 centavos... faz parte do jogo 😅
Why don't they run steel studs with aluminum nuts That's how my 1071 setup from BDS
Be careful
better luck next time
So it went lean and Kaboom! That will do it that's what I thought happen because you were not even pushing the engine it was only half of it's full potential I did not know it was hybred I figured it was full EFI.
Push my stock parts and go boom too!
With that type of explosion you should check for bent intake valves
They said they did a compression and leak down if it had a bent valve they would of seen it on the tests
@@bigboreracing356 and this thing would gap tf out of them bc it makes way more power wayyy more precisely

If you ain't bracking stuff you ain't trying new stuff
So maybe all mechanical, how many times do electronics fail / half fail … their is no check engine lights on old cars …
Guys, there was absolutely a burst panel there.. watch the first 30 sec, and you will see the panel bursted.
Thank you!
I stick with my Made In The USA Billet Atomizer injectors.
Sounds like reason to stay all mechanical
Gonna blame , " it got no gas " . .Just saying
You sound like you’re from Florida or Georgia 😂 i have no idea but you sound like my uncle
lol we’re from North Carolina just as bad with the southern draw

You love to hear yourself talk without saying anything. How many ways can you say the same thing to fill time in your video. Get better
Ima say it went lean, that’s normally what happens.
"They" said it went lean too.
That's what we call a cough. That's why we have blowout plates on our blower, especially want to run a nitrous
Brrrppppppp
Usen Ford..
I told you so ! Your system is contaminated. Time for a complete redo. Also your system needs to be in balance. Yours in not.
Elaborate
Lol.. proof that you never invest in metal...
Yeah you Don t wAnna be running stoich on methanol at WOT. This aint c16😂
Haha lean is mean right? 😂
😂
