Could be the coolest pic ever...

I couldn’t work and look at that all day... I wouldn’t get anything done!!!

 

[oldschool]

Can you imagine how that thing would have launched with all the cylinders lit?

 

[checkrd past]

What makes you say there not?

 

[4Waters]

What makes you say there not?

There are at least 2 dead cylinders, one on each side. The white coming out of the exhaust is raw fuel.

 

[blue wonder]

It is done on purpose with timers for the ignition timing, can’t make a boat leave with a full 11,000 horsepower

Definitely not done on purpose

 

[blue wonder]

So your a boat racer and know people that run top fuel boats???

 

[blue wonder]

And I guess you know Scotty Lumbert as well???

If you know the answer then why ask, I have been following drag racing closely for nearly 35 years, you pick up a thing or two over the years and I have helped with a friends nostalgia top fuel.

Is a great pic!

 

[Hardly Satisfied]

Sweet picture

 

[blue wonder]

Ok well “following” drag racing and being a part of it are completely different, I am involved with the sport pretty heavily and your comments are wrong, just sayin...nostalgia top fuel on asphalt and boat racing are two entirely different things and the way things are tuned

 

[ElAzul]

Poor Scotty hope he's doing better. Anybody had any contact with him lately?

A dead cylinder is a dead cylinder.

He is doing pretty well considering, making more and more progress every day

A dead cylinder is a dead cylinder.

Yes a cylinder will be dead on a fuel motor with all the timing ramped out of it, they will re ignite after the timing is put back in

 

[4Waters]

Yes a cylinder will be dead on a fuel motor with all the timing ramped out of it, they will re ignite after the timing is out back in then

So the tuners want cylinders to go in and out throughout the pass, then why not just run a 6cyl

 

[4Waters]

I know it's not uncommon but it's not what they want, and timing is just one reason why cylinders go out

Guess you should be a tuner for a top fuel team since you know how to run one better than they do, should probably wait by the phone tomorrow for the call to take over the program, hahahahaha

I read it as cylinders being not fired on launch and coming in after a timing/programmed point.
The can’t launch at 11,000hp caught my eye as a reason why.

Yes that is correct

He probably didn’t think it was cool

 

[blue wonder]

Lol, yeah probably not...too much power and props too far back, not a good combination

 

[4Waters]

Yes that is correct

As you know most guys here follow drag racing, if something is a little different about hydro the educate instead baiting.

Now that's a launch NASA would be proud of ! Probably not a good way to win a race though eh?

This should explain it.

Why pump all that fuel through a dead cylinder and then light it further down the run? I would think there were better methods. Enlighten us mere keyboard mortals please.

 

[bonesfab]

I didn’t know on a full mechanical engine you could randomly kill cylinders and bring them back in. Retard the timing yes. But not on an individual cylinder basis.

 

[Carlson-jet]

Cool pic.
I know nothing about tuning top fuel but it would make sense to kill the spark and lite off the cylinder than to try and manipulate fuel then lite it off. The second scenario sounds like burning up a cylinder.
Is there a clutch for 11k HP.
I know a few guys who run Lenco on far less HP.

LMAO! Now That’s fuckin funny. BTW I understood it as posted, same as GC.

You can with a two step limiter or the msd grid and others.

 

[Checkmate21]

Ever heard of a slipper clutch? You do not want to drop cylinders on a fuel motor!!! It can get very expensive very fast!!

 

[HighVoltage329]

I'm no expert but once the spark plugs are that wet it's difficult to get them to relight. Great pics.

I don't know if this is common practice for every modern TF motor, but I have seen injectors spraying fuel into the blower intake, my guess is to begin the fuel atomization sooner. If this is the case in this pic then it would be impossible to eliminate all the fuel going into a purposely tuned dead cylinder during launch.

 

[Tommy Gun Images]

TFH has always been a favorite to shoot for me. Just amazing machines!

 

[Sharp Shooter]

I love Top Fuel Hydros, but they're just not practical. Do you get a matching watch when you buy one of those?

PRACTICAL. LOL

 

[liquid addiction]

I would think it has something to do with the whole boat out of the water and a normal launch would not come out like that. With the props out like that there is no load on the motor. My understanding is that a fuel motor needs a load on it. When the load goes away, the RPMs come up which spins the fuel pump faster, which increases the fuel pressure and pumps too much fuel into the motor, and ends up drowning out the spark.

One thing I can tell you, I have been next to them on the rope before and they are crazy when they launch. Kind of always slide over as far away from them as you can.

 

[Dana757]

You better have your affairs in order before you climb in one of those. Awesome picture!

 

[monkeyswrench]

Practicality...
The hobby of boating...
...then racing...
Then we aren't only adding race fuel, adding nitro. Nitro, basically crystal meth for engines. Great until full cardiac arrest.

...and shit pukes it's guts out

your answer is dead on and yes I know a fuel boat owner and Scotty. I was on the rope at the world finals and Braksma to off with the rope scary.

Yes this^^^^^^^^^ ProMag44's

 

[motormonkey]

Pro mod alcohol cars use traction control and 2 step on the line to build boost with a blower for sub 1.0x 60 foot times. Been done for years and the extra fuel just gets blown out the pipes. Rich is fine, lean is when sit hits the fan.
Tuning for for shifts is where the magic is at. A mag 44 with a grid will light a swimming pool on fire.
As far as top fuel I'm guessing a few similarities and don't know.

 

[liquid addiction]

I am by no means a TFH expert, but water and asphalt are 2 totally different animals.

Once the fuel teams got the twin props figured out, there isn't anything prettier than a full pass from one of them. The learning curve went from submarining them at the hit to blowing over like the pic of Glen Wilson. There is a cool sequence of Plum Krazy wheelieing all the way over at Red Bluff. I think I have heard the prop speeds on them are around 22,000 RPMs.
