Scaling

[doyle hargraves]

I recently picked up a new roller from a well known chassis company and When I was going over the setup sheet and load numbers with them I asked about rear and left side percentages They told me they don’t even pay attention to them anymore just set the wheel loads and race. Said only reason to scale it was to check total weight. What’s you guys opinion on this?? Probably gonna throw on the scales anyway just out of curiosity

[CCHIEF]

I highly disagree.

I highly disagree.

I agree with chief, disagree with their statement also.

Only way I would partially agree with them was if you bought a complete roller and every part was exactly the same and driver weighed really close to the 200#, but I would still set on scales to verify the left and rear % anyways but could see a guy could skip that if 100% every part on car was what they wanted exactly. That would have to include motor, battery and several things normally not bought with a roller.

I got a complete car minus engine and trans but I am still gonna scale it just so I have a starting point of reference. They did tell me where to add weight if I needed it to make minimum. Thanks guys

Smash numbers do not get your left side and rear percentage correct. You must scale. As has already been said.

It wont do you any good to scale it like that.... I needs to be race ready with driver and fuel just like your gonna race it then you can scale the car. You cant do it without the motor and other stuff in there for weight...

[doyle hargraves]

I know that. I mean when the car is complete. Thought that went without saying.

[doyle hargraves]

Mbr. I know that you have to physically move or add weight or components to change left side or rear percentages. My point was that they say they don’t worry about those percentages which I thought was strange

[MasterSbilt_Racer]

Yes. That is bad advice.

I would be really scared of that manufacturer. Just because we use smash numbers now instead of scaling has nothing to do with percentages and they absolutely still matter.

Relative kid bought a capital to run in 604 crate. He used their smash numbers and was fast right out of the box and won second night out in it. Two years ago and many wins and car has never seen a scale.

That does not disprove physics. They may have told him where to put weight. His percentages may have just come out correctly. Hang 50# over the RR wheel on that car and come back to me.

I once ran ,3rd in a 24 car field without a spoiler. That doesn't prove its the way to go.

How much weight does a newer DLM typically need added?

I know on the mod side there are several of the newer cars that take no ballast at all to make weight. A lot of those guys smash and go as the percentages are built into the car.

I'm maybe too old to not scale something, and our cars need lead so we are on scales and those %'s matter to us.

What does a 130# guy do? A 350# guy?
