At What Point Is Adding Weight A Good Idea

My 89 Cummins Puller weighs in at 5750 with me in it... Seeing as how I am in a 8000 class that leaves ALOT of weight I can play with.


I ran this run with 1600 lbs in my tool box because we can't hang weights but can add it.

Then I made this pull the next weekend with no weight added...

I pulled farther and faster w/o the weight... Was this a fluke? I'm thinking that my little VE with just pump mods does not have the power to get the extra weight down the track...

I have since added some POD's and now and in a delema... Do I add the weight this weekend or not?
 
Every sled and every track is different. 9 times out of 10, adding weight is a good idea. If the track is too tacky, drop some weight. If its real loose, weight up as heavy as you can.

Ok... That makes sence... My problem is that I can't get the wheel speed up. The 3.07's REALLY kick my ass.
 
What size tires are you running? Anything bigger than stock and your ratio is down in the 2.90's or 2.80's. I'm surprised it moves the sled at all. You better drop some lower gears in it before you start breaking stuff that will cost you alot more.
 
I prolly know of a buyer/trader for the 3:07s if you want to trade.


Easy on the weight unless you have the drivetrain to handle it.
 
Tcolsanti is right. Every track is different. You can't tell how much to put in or take out till you look at the track.
 
If you have the drivetrain to handle it, then adding weight will usually get your father than not running any.

And i hate when people compare distances from one sled/track to another sled/track. It is totally different. Even the same sled, on the same track a month later might be different because of how the sled is set. I know that is the only comparison you really have, but its not a good one usually:hehe:

Are you running a stock auto?

Stock Auto right now... TC is on the way along with the Shift Kit...
 
That will make a bigger difference than about anything at this point. A good TC and shift kit will really wake em up.

i doubt adding weight to the bed will do much i might help af the start but when the weight of the sled gets on the truck i thing it will hurt more than help. if you can hang weight on the front do it. as far as the gears go if you truck has 3.07 gears then it has the dana 61 front axle wich limits you on gear choices as they are different and will not interchange with a dana 60.
if the trans ic the stock 3 speed then it is a torqueflight 8 the same trans as they put behind the hemi (the real hemi) and if you dont drive the truck on the street then i would recomend changing the valve body instead of a shift kit. a cheeta manual valve body will help you a whole lot more than a shift kit plus you will be able to hold it in any gear you choose.

If the Torqueflight 8 is the same as a 727 then yeah... :hehe:

You can get 4.10's and 4.56's for the 61's now.
 
its the same. you gear chiice will depend on what you do with the truck if your going to street drive the truck then anything lower than what you have will not work. unless you go to an overdrive trans.
 
I have yet to see a situation where taking out weight would make a truck pull better. But I'm still learning. $.02

Truck is a play toy/puller... As long as she will run 55 I'm OK!

I'm thinking 4.10's will be about right
 
1:1 Tranny with 3.73's at 55mph puts me at around 2200rpms...with a 265/70/16 Tire (i think thats what it was when I tried it)
