Brian Morrison I thought I was the only one that saw that and died laughing! I think he was so in shock that the fucking thing blew up or embarrassed, that he decided to keep on checking the exhaust temps!
This motor was lean all along but what I found more disturbing was that they were doing this warm up with NO one in the car sitting down.. a dangerous combination
NHRA rules state a driver must be in the drivers seat anytime the car is running in gear.... if it came off the stands it would run uncontrolled until it ran into something... they would be banned for life at our track
Correct. Just like light helicopters being started and the main rotor spinning, yet the pilot is operating it on the ground, the same with these third class drivers who think they know fuck all. Imagine if the car vibration makes it slip off the jack stands and the spinning wheels drop on the ground at high speed, what will happen to the fool who is right in front and on the path of the wheels? I'd hate to think of the outcome, similar to a meat mincer, I'd say. Shit for brains 😕
@@heyderzlawson9700 Jack stands have been known to slip from the car vibration, especially from unbalanced wheels, causing the car to fall and the wheels get a grip and cause the car to take off. At least with the driver sitting in the cockpit, he has time to kill the engine and brake the car.
Yeah I was curious about that, was a big no no, when I raced juniors with my son. Even so someone did it anyway at my local track and somebody got hurt.
Blowers like that typically use aluminum studs to hold them in place it lets the blower pop and do less damage. It's annoying but at least it wasn't a big boomer.
+iCloud Henshaw no blower on this car just injection and with the fuel pressure in the system there's plenty of fuel spraying into the manifold to keep the engine running.
I've had a engine run on before in the pits, with out spark. I was quick 2 smother the injector 2 shut it down and save the engine. Lucky it happened in the warm up because it was a motorcycle. Tommy, u r 2 b commended for the work u and your helpers have put into this engine.
@@superrodder2002 look again. They need a whole new blower it cracked in half. Not to mention the whole motor now needs gone thru cuz you never know what could have happened thru all this.
@cfaulc Thanks for giving me the heads up Its been a few years for me now running comp. I run a 70 Nova with and NRE twin turbo charger now 402 with an alien intake and on pump gas shes pullin about 1500hp, switch to both fuel systems on the fly and increase boost she pulls 2100 with 1950ft lbs at the rear wheels. Daily drive runs like a kitty kat with the AC on.
It doesn't need the blower to run. It will only be atmospheric pressure. And if someone in the best position to shut it down didn't, then I would guess someone would need to tell them.
They tried to kill it the only way to stop a fuel motor is to cut the fuel looks like enough fuel was getting in to make it run super lean revs went up and well pop
Something else to add. I have been watching drag racing at the strips since age 9 or over 54 years. Racing safety has been incredible in the development over the years. Also, fan enjoyment has grown great over the years. The sanctioning bodies, NHRA, IHRA and others have to please fans, racers, TV and other sponsors, and insurers, a tough task indeed. So, I really don't know where all the solutions lie. Just like so many others, I love the sport. I just want to see the sport flourish,stay safe and interesting as well.
@Scott-tv6vcDrag racing has a lot less deaths than other forms of racing... but it is racing at the end of the day. Death is a possible outcome. The drivers know it. The fans know it. It's a risk the drivers are willing to take, so it's really not a good reason to dislike an entire racing series because of possible deaths... the human body isn't designed to survive anything worse than falling over, so yes.. racing is potentially lethal.
Wow, bummer.... but there is SO much WRONG and DANGEROUS things going on here! No driver in car, running driveline WAY too fast, owner climbing all over front of driver's compartment while engine running...... scary stuff!
It's interesting to see how flexible those back tires are- every time you increased throttle, the diameter of the tires got larger. Quite the contrast to your average road tire!
Somehow, the first thing I noticed when the engine blew, was the deformation of the tires. The centripetal force starts pulling the tire at the center as it rotates faster, and you can see the affect right before the blow blows if you watch the tires. Physics has always interested me
The walls of those tires are extremely soft and ran at such low pressure that during launch, they crinkle, then at speed they balloon out, which weirdly changes the gear ratio acting like a transmission of sorts
Physics might have interested you but english language and participating in an elementary school spelling bee is where all of your attention should have gone
Yes Jake Wood. I've never understood having any car running on jackstands or a lift without some that can operate the brakes etc. Doesn't take much of that torque jerk to cause mayhem.
To be fair, anything above 4 liters these days, is a large capacity engine. Heck, the amount of power they get out of a measly 2L engine in rallying these days is incredible. They are also pushing a LARGE amount of Air into the cylinders at the same time, because you get no burn without oxygen ... thus it would be real difficult to hydrolock. But yeah, they do go trough a lot of fuel in an awful short amount of time ... that's part of why they are so exciting. :)
2:19 Random bystander chomping on a hotdog and sipping a soda is like " fire , fire , YO GOT A FIRE " as he's pointing at it with his food hahaha idk why but it was funny
@farmerbrown29 naw, most modern engines have direct fuel injection, so the blower only compresses the air, thus there would still be enough compression and fuel in the cylinder to keep the engine running without the blower, but power goes way down.
at idle those wheels are moving faster than my car probably tops out at, let alone the fact that if i passed it sitting still while i was at top speed it could zoom past me literally less than a second and a half later.
***** I saw Gale Banks running twin turbo's in 1986 at seattle on a top fuel rail. They could never get it to make a full pass because it kept blowing the turbos but it sure made a lot of power for short periods of time. Sounded really weird too.
It is still valuable info. If you get to it before it cools. They now know what temp is the danger point for that motor, and stop it before it gets there the next time.
Classic Example of not knowing where the fuel shutoff is. The only way to shut down a Fuel motor is to turn off the fuel to the motor When the motor is at a high RPM it is leaning out by burning more air than fuel.
Nick Edstrom I think what he means is that they don't "burn" air, since it is composed of mostly inert gasses. The fuel burns. and as for the ratio of air to fuel, there is always more air then fuel if it is running. Also, this motor never gets near what would be considered high RPM, if it did the tires would explode and shortly before the motor, you don't run a motor like this anywhere near full throttle without a load. Why it takes so long to shut down is that between the time they all jump back and they older gentleman with the blue hat hits the shutoff some fuel was built up in the intake system that was enough to run the engine without any load.
Nick Edstrom you know the fuel pump runs like 100 gal/min so not going to be lean but being lean will melt the valves. and no one gives a fuck what your dad drives
I wish you had more videos of the twin cam im dieing to see inside!!! People are hateful and ignorant comments are from jealous minds. the engineering involved is staggering i would love too see tommy at the vintage drags!!!
Actually, you drop the throttle to "zero" then chop the fire. If you cut the fuel first, the engine goes way lean and THEN it backfires. But like you said, hydraulic will ruin your day just as easily. And, also like you said, by the time you're at half track, a blown nitro engine doesn't have spark plugs, it has glow plugs. A little "factoid" I saw long ago. A TF engine will turn less than 600 revs between clutch dump and shut off.
ok,....that thing sounds like a death trap and judging by the way that trailer is dumped out to the back like that, I'd say these guys should not be allowed to race anything bigger than a small block Vega or something like that.
@rd2fst My point was that you dont time an engine at the headers but by way of timing marks on the balancers As for theas engines not having balancers i have seen them with and without if without then the blower pully has the marks on it The two that we sponserd had balancers on them
How are they fools? They were doing a prerace check that every other team does. They can't help when a part decides to go bad. Lay off the caps lock and think before you type.
No driver in the car. It could run away. There are rules regarding this at NHRA events for reasons. Then they grenade the thing. I guess it's not that serious until someone dies.
That looks about as dangerous as it gets, two huge tyres spinning like fuck, unguarded with guys walking past them, on axle stands, a fucking accident waiting to happen. Gotta love amateurs.
Dangerous group there I’d stay clear of that pit area for sure I’ve wrenched top ally and top fuel funny car and always had a driver in the car in case of any such problem they are just dangerous and a bad time waiting to bestow anyone near them you would think if they were intelligent enough to build the car they would use some sort of intelligence to prepair it No excuses for short cutting it never ends well
Reading from the comments "its running lean" is a possible reason for this blow. Why would running lean cause it to blow? Just curious on the mechanics of the fail.
Is this an experimental dragster? It seems to be very short like the new nostalgia class but has a modern engine and rear wing! Does anybody know anything of this project?
Timing was off or a valve was bad that’s why that rag moved because the exhaust was sucking air when the motor backfired which will blow the top of the motor off with a blower like that
I wonder why blowers explode? I mean, there's not all *that* much pressure in there. It's not 1000 psi or anything. Is it because the engine backfires through the intakes?
Hey, at least they now put those convenient straps connected to the blower to keep it from launching itself high into the air, maybe injuring or killing someone.... I'm surprised it took so long to implement that idea. How many superchargers have you seen in video clips exploding into the air, when the car's halfway down the track?
@dozer3955 Yeah, it's when you lean it out too fast. Like say, if you pull the fuel with WOT. Or the pump quits pumping. I've seen blowers also go off after a quick rap. Fuelers (actually any mechanically injected engine) like to run at idle or full tilt (aka WOT)
@TsS7VEN Well, maybe, but NHRA and IHRA both require a driver whenever the car is lit. If they tried this at a track they'd be on the trailer in a heartbeat. Have a license? Have a rule book? Know how to spell "shut"?
@nelzxws timing light???? all I seen was laser heat sensing gun all timing lights need to be hooked to the #1 cyl and batt andis aimed at the harmonic balencer not the headers

you could hear the engine leaning out .They should have killed it when it started to purr instead of the crackling sound.
purring is a nice sound for NA

steer and brake, actually. if the car fell of the test stand then who who would stop it and/or steer it away from people? use your head.
Brennan Visniar
the brakes will not stop the car under power, the front ends are picked up for "steering".

I dont think they know exactly what they are doing by the look of it.
They did, the owner told them to shut off the engine at 1:48 but they didn't.
If the owner is the guy with the hat, he is the one who had his hands on the kill switch. These guys are newbs for several reasons.
too much money and pops tune showed them how to spend a little more.
I just noticed, the guy in the blue hat said to kill it about 7 seconds before it banged the blower.
It doesn't need the blower to run. It will only be atmospheric pressure. And if someone in the best position to shut it down didn't, then I would guess someone would need to tell them.
Yeah I see it now

what if that car shook off the jacks.
Looks like it's back to "U PULL IT" for some more parts..
Those cars scare the shit out of me standing still with their tires in the air.
so; what was the cause?
running lean or wromh timing causing a spit back that ignited between blower and inlet valves?
What do jack stands have to do with the engine blowing up?
