BC Broncos racer crossed up

[chuck]

This is the only picture of our racer that I could find of it doing anything.
We are making a left turn as you can see from the dust behind but look at the right rear tire.

 

[Potshot]

That's a sweet shot

 

[73stallion]

that'd make a good screen saver for ya chuck!

 

[Revelation]

Great Shot Chuck..

REV that avatars gotta go!!!!!!!

Is REV a female? Or a tranie?

Thats a great action shot!

 

[Revelation]

Nope, not a female, But I do sleep with one most nights.

what psi you running? that particular tire has a really stiff sidewall.

 

[chuck]

We started with 28 psi. Jason slid around a lot of corners and not long after that picture he tore the sidewall out of that tire. It was the 2ed tire he distroyed that day. On this one the rim was still good, the first one he bent the rim (his norm) also. My guess is we lost some air before this picture and a lot soon after. We were running around 50. Low tires pressure, speed and rocks do not mix well.

I know a place you can get a new fender.

 

[chuck]

We are retiring this racer. I think I will go back to steel fenders, door skins and 1/4's. They might hold up a little better.

 

[Ratch]

Crap! I am stuck in San Antonio on business and cant sneak up to your shop! Maybe some day.....
At least the company ponied up for a nice room

 

[malonejy]

Cool pic Chuck.

 

[RIbronco]

Nice picture!
Retiring that racer, eh. Does that mean another one is on the way with improvements from what you've learned with this one?

 

[chuck]

Yes it is already started, hope to finish before the next race in April. This is the 4th class 3 we will build. Lots of changes, mostly to improve handling.

 

[68ford]

a lot lower ride height? dont do like several and go to a lot of trouble and end up with it not being that much better or possible even worse while taking a lot more time and money to do so.

 

[chuck]

The last time we reworked this racer I lowered the frame/body 5" into the suspension, that worked out fine but I don't see more lowering and still have the 15" of wheel travel so not lower just more stable so we can go around corners faster. I have some ideas on how to make that happen. Maybe someone here may know the fix. When we give it full throttle the rear end fishtails way too much, like being on ice. The only way to stop it is let off the gas. And less throttle helps but the idea is to get gone ASAP. I can't go to wider tires because of rule limits. I don't think tires will fix it because it does the same thing on dirt, sand, gravel and rock. I am thinking bias to squat could help.

mine has stock body mounts so i go off frame to axle measurements. after my 3 year project, taking out a few times and adjusting ride height by adding then removing leafs. mine ended up 1in lower than stock(someone else comparing axle to frame and telling me) with 6-6 1/2in up travel from ride height. when the rear is bottomed, the axle tube is 1/4 maybe less from touching the bare frame rail. original bumstops and plates all gone. to get it this low i put the rear shackle bushing 1/4 in below the bed right at the rear of the body and moved the front mount up several inches. it uses all of a 3.0 16 inchtravel shock.(fortunate to have a friend at king to help tune, which i think is class 3 fail point, suspension really working like it should). one thing that helped a ton with raising the front mounts is i ended up (by luck) 0-1 degree pinion change over 18in unstrapped and less than 1/8 drive shaft plunge. i think plunge affects suspension movement greatly while under accel or deccel. your front obviously cant be as low as mine due to not being able to c notch for the trackbar and draglink at full bump. but still as stated every class 3 eb i have seen has been super tall. i have watched hours of you tube videos and still feel that if you look at what keeps eb(besides breakage) especially from improving speeds is not properly tuned suspension.
i also think the huge disadvantage of unsprung weight can be offset by increasing the weight of the eb. mine weight 5500pounds 40 gallons of fuel but no tools or anything. 2800 is the rear and 2700 in the front. i think all that weight especially in the rear more than makes up for it being a little slower by improving stability and suspension operation.
new front end is in the works, but here is a pic where you can see that keeping low ride height is totally possible.

check out the king(go figure)sponsored buggy at 42 seconds. never seen a slass 3 solid axle truck this smooth or a solid axle move so freely under a vehicle while the vehicle is so smooth. so it can be done.

I was gonna say, looked like a lot of pressure on that tire.

Great shot though!

that looks like an absolute blast
