Mud Bog Tips

[75Bronc]

I entered the Mud Bog at the county fair this weekend. Wondering if any of you have tips for my run. What psi should I run on the 35's? Should I run in low range or high range? I have a pretty strong 302, but I am high geared, 3.50's and c4. I currently have the top and doors on, should I shed the weight?

Thanks!

Yes on shedding some weight, especially in the front.

PSI in your tires does not need to be real low. I would say 25 and above.

With your gearing and those tires I would run in 1st gear with the transfer case in 4 high.
That will give you the wheel speed you need for forward momentum in the mud. Tires will clear the mud from their tread with more wheel speed.
If you find you do not have enough grunt to push through the mud with that combo try 3rd and transfer case in 4 low.
Remember that you do not want to be geared too low in mud. You need wheel speed.
It is a balance of enough wheel speed to clear the mud from the tread but also enough gear/grunt to push through it.

I would suggest keeping the top on to help distribute more weight to the rear of the vehicle. Shed the doors. Wheel speed is your friend.

3.50 gears + 35" tires equal low range in my opinion. The mud will created a lot of resistance and you'll appreciate low range once all 4 tires are submerged in the mud.
Once you actually do it and are cleaning out mud for the next 5 years, you'll probably wish you would've just watched.
Other tips, unless your Bronco is just a mud bog machine...
► try to implement some type of shield under your motor to prevent your engine bay filling up with mud
► give your Bronco a good waxing before you do it
► windows up
► try to protect / fill small nooks and crannies to keep the mud out of the undercarriage
► if you have to be pulled out backwards, watch out for mud going up your exhaust
► try to get as much wheel speed as possible... if you run 4 Lo, don't stay in 1st gear too long unless you have a rev limiter

Most events have a fire truck on hand offering free washes after the run, take advantage of it - the mud comes off much easier while its still wet

If you are driving the Bronco there and home, watch out for poor brakes on the public roads if mud packs in your drums / calipers

that's about all I got - have fun and seriously consider just watching - that mud is awful!

Silicone the electronics n plug wires! Let it all hang out.

Don't forget your fire Extinguishers

A trick we use A lot here in Florida is to spray down the under carriage with PAM or Amor All.
We get one gallon jugs of Armor All, lol.
With everything liberally sprayed down mud has A lot of trouble sticking. What does stick washes off really easy.
I Can Remember not wanting to spend the money on all of that Armor All, but after trying it I realised it is worth the money. Your truck will clean up sooooo much faster.

Thanks for all the replies! I'm still torn between low range and high range. Any other opinions on this?

Give it a test run in a field or pasture. Make a couple of passes to see what you think.

 

[Apogee]

I would run it in low-range with the reason being that if you need to downshift from 3rd to 2nd (or to 1st), you can do so, whereas in high-range you have nowhere to go below 1st other than low-range, and that's not a quick shift.

Tire speed is your friend, but so is HP...and your 302 is still a 302 at the end of the day.

X1000000 on the Pam/Armor All/WD-40/etc as it really does help with the clean up. Plus, the less mud you have stuck to the undercarriage, the lighter you'll be.

Depends on the distance? I ran some yrs ago mostly short range boggs 4-Low n drive .

In motocross mud bog races, pieces of foam are used where ever mud can collect on the bike. Makes me think of the splash shields on the mid year Vette. Maybe design temp shields to keep the engine bay cleaner.

Post a video of your fun!

Diesel works well, also. Use a pump up sprayer to apply it.

Low range second gear would be my choice. If it's true mud, if it's thin soup with a hard bottom high side first gear

I used to race my F-150 in mud bogs years ago. I was running a 400 with a C-6, 3.50 gears and 36" RVT's. My motto was the three "f's"....4 low, 1st gear and floor it! I won quite a few trophies back in the day too. You might want to try it.....

It's true...you'll be cleaning mud off and out of it for the next five yrs. I hate mud. Running in mud means you have to keep the pedal to the metal full time and doing that means something is bound to either give up or break or both. If that is a pic of your Bronco up top it's too nice for mud bogging.

All true /\/\/\

I like sugar sand. You can play all day and your rig is still pretty clean.

We use to push sprint cars on a wet track and used mineral oil in a spray bottle sprayed everywhere. Very important to grease your suspension, u joints and drive shaft to keep the wet grit out. Remember to clean out everything when your done before it all hardens into a brick. Then re grease everything to pump out the grit and dirty grease.

I used to race years ago 289 3 speed 4low 33 inch buckshots I iwas dumping the clutch at 5000 one run had front tires off the ground end up fastest time of the day: so fast wheel speed is a must also bring extra water for cleaning wind shield between runs and to refill resovore, might need helmet and seat belts to race

I have a half cab on 35 x 14.50 boggers. Spool in rear, Detroit Tru Trac in front. C 4 reverse pattern full manual valve body and 351 Windsor w about 400 hp. I run 4 low in the deep mud pits. I start in first. I can always shift up if needed, but rarely do. It's good to keep rpm up in mud running. If you have too tall of gear, you will bog down and not go far. My guess is you are doing a deep mud event. If it's mud drags, I still say 4 low. You can always tach up rpm and upshift.

I don't bogg but my dad and brother do. Depends on your setup. My dad has a 200 in his 66 so he likes narrow tires due to lack of HP. My brother runs a 700+ HP stroker in his 77 and runs 38.5" boggers. Light weight and gearing is a plus. Don't have all the details on their rigs but they have fun. That's what it's all about.
