putting lead in carriers?

Why is the lead filled carrier adding constant resistance? Im not necessarily disagreeing, just not quite subscribing to that belief.
 
think of a baseball bat. you can spin it relatively easy by the handle. now add 40lbs of lead to it. same principle. people want to say it is harder to stop once it is spinning. but add in the resistance of the sled. the resistance of the tires(more weight). and how much harder is it for you to spin a bare bat compared to one with 40lbs added to the end? takes more power. there is a reason the big guns( scheid, haisley,enterprise) are not doing this to any truck they put out there.

By your theory, a small block gas puller with the same horsepower, torque and gearing should outpull a big block gas truck.


It make take more energy to get the heavier bat moving, but if you let it go to spin on its own it will take more energy to stop it.

Set both carriers, lead filled and not on a set of rollers. Spin them both up to an equal RPM, then let them free wheel. Which one is going to spin longer on its own? Granted one took more power to achieve the same RPM as the other.

If i had an endless supply of money for high dollar spools and high dollar axle shafts, i probably wouldn't be messing with some half assed weighted carrier either.
 
you are right. but there is that one term you used that does not happen in truck pulling. free wheel. pullers have resistance. not only the tires, the sled, but now 40lbs of added carrier weight. trying to get to top rpm is harder. and because of resistance, harder to stay there.
 
The reasons the big guns aren't doing it, is that it's a cheap simple-ass redneck fix for what most people would just use a spool for. Part of the advantage to most aftermarket spools is that you're getting it made out of a better alloy steel that should last a long time.

If you would stop and do the math a little bit, the extra added rotational inertia of that small slug of weight (at a small diameter) is trivial compared to the inertia of six 33" or 35" tires at say 100 lbs each. It's likely the driver would never feel any difference.

You're overthinking this a bit.
 
I agree far too little weight on a tight axis of rotation. I doubt you would even feel it.

Thank you, thank you, thank you.
 
pretty sure most of the guys at the top of the class are using spools but not only for the locking part, they allow you to run larger spline axle shafts
