Ok We weighed my pig

NOT with this one. if I had them here I would take a pic for you. it would speak a thousand words. maybe with an attachment for the tongue to sit on the fulcrum. then these could be used for this purpose up to 1200 lbs. the fulcrum plates are built to hold a tire.

 

race car scales

This is the kind of scale setup you need to beg, borrow, or steal.

The car is rolled up onto this scale, jacking it up, and then setting the wheel down on the scale will not give an accurate reading. Hence the ramps in front of the scales.

 

They are electronic pads, and this is the readout box. It gives cross weighs, front/rear weights and percentages automatically.

I don't own these, it's about a $1500 setup, 5 local Buick racers got together and bought them a few years ago. They end up in the shop from time to time, and are essential tools once you reach the 9 second range with a big car.


This car loves the rear weights equal, with the LF heavy. Goes straight as an arrow. And I do mean, take your hands off the wheel on even a marginal track, and it goes straight! If the rear weights get goofy, it jumps to one side on the launch. That's our que to put it on the scales, and check to make sure the chassis did not develop a bind, you do this by bouncing the front or rear of the car, and making sure it comes back to the same reading, which is one of the most important functions of scaleing a car.

I suggest that you get together with the local Buick guys in the area, and all pitch in, and get a set of these. I have seen similar sets in the $1200 range.

The readings in the picture are pretty typical when the rod ends get dirty, or it gets bounced down the road in a trailer for 800 miles. Also, there is no driver sitting in this thing right now.. wish it weighed that with driver..

PS.. I had a car that weighed 4110 with me in it, a full weight, all steel, full interior 70 GS, and I agree that you need to work that 60 foot time, as that car, with only 560 HP, would go 1.48 60 foots, even though it only ran low 11's in the quarter.

 

Yup, that is the MacDaddy setup my brother has. And, JW is correct, NEVER drop it on the scales. ALWAYS push it on.

Then again,The are guys out there going 8.0's with 3000lb cars that have never been scaled.....Sometimes we make things harder than they have to be.

Me for instance,Had my car on 4-wheel scales this year and learned a little but I don't think it's the be-all-to-end-all......

Thanks for the compliment,Hopefully some of what I've learned over the years at least shows up in the way my car works.

Wow Perry..1.30s. :Brow: :laugh:

 

Still looking for a ......ahem......lighter driver.......
It may sound obvious, but you have to make these things rip off the line. One of many things Tom Rix has handed down to us is that you make them 60 foot. 1.26 I believe was his best which is nuts considering a 9 inch tire.

Car has been put into storage indefinately will worry about this next year.
