That's a great little program. Small, free, easy to use. Only trouble is I had to download it 3 times before I could get it to work and when I shorten the footage the size actually increases dramatically.

incidentally, found riva to do that free again, and seems to work great.

That looked a bit too big and complex for me.

I've been following this from the beginning and I must say I'm impressed. This project is much like our Trophy trucks or Pro 1's. The only real difference I see is the transmission and suspension.
What kinda terrain do you run on?
We have a few of your mates from downunder come here to race once in a while, and they do quite will I must say.
The bottom line is were ever you are it's a blooming blast to get out in the bush and let it all hang out.
Your gold "Monster" makes me want to build one. Might even paint it gold.
I personally have a EZ30 turbo'd rail and working on a EJ20 super light class 1 pro.
I love this site and enjoy seeing what you guys are doing.
I'm looking forward to see the "Gold" bring home the gold. Beautiful car.

Welcome MelAdjusted. Looks like your in the right part of the world for off-road racing. If you go to youtube and type in Finke, you will find alot of footage of the kind of terrain we have. I have a couple of short clips and pics here from my trip to the race - http://s45.photobucket.com/albums/f97/p ... %20around/

MelAdjusted · Post by **MelAdjusted** » Mon Jul 02, 2007 2:06 pm

From the clips looks like your running the same kinda chit we run. How much wheel travel does the Brumbyrunner have? What kinda of top speed does it have? Some of them flat out streights would be wild for top end:D
I have a million questions and I hope maybe some answers. Im always interisted in racing, any kind, thats what I do for a living.
I don't want to hi-jack this thread. I just wanna see the Gold Monster kick aome donkey.
Thanks for the clips. Here's some of our play grounds.

I think some of the 'better off' racers import some gear from the states, maybe even complete cars. As for the rest of the questions, they would be better answered by brumbyrunner. You certainly are lucky to be doing what you like.

Hi there MelAdjusted.

I would love to come and run the Baja 1000. Even got it penciled in on my diary, 10th to 16th November. However my sponsers will have to dig deep before thats going to happen.

To answer your questions, I dont' have much in the way of suspension yet. My aim was to get the car built and log-booked ready to race and then start on some decent suspension and brakes. I'm looking for about 10" of shock travel in the front and 12-14" in the rear. Don't know yet how much wheel travel that will equate to. Not much by buggy or trophy truck standards though.

Top end? Still sorting that out and I will have to drop the final drive to 4.444 with a 3.9 gearset to get the gearing I want but looking at 225km/h at redline in top gear.

We have the Baja 250, Baja 500 and the Baja 1000. I'll be running the first turbo'd car in SCORE. Desert racing never allowed turbo cars but there allowing me to run a pilot car and see how I do against the Trophy trucks and Pro1's.
Your on the right track when it comes to long travel. The more travel you have the faster you can run in the rough. You can never have enough travel. I kinda looked at the dirt bikes suspension and used it as a example to design mine.
Your truck kinda looks like a mini Trophy truck. I like it.
If you can get it up to 30+ inches of travel you'll be able to use your hi top end speed better. Rough chit that beats a normal car to crap, you'll float over.
What are you using for tires?
Your transmission is a 5 speed standard?
Is your engine turbo'd?
Sorry for all the questions but I just like racing. It's my life and the one thing i've learned about life is, "Life is like a roll of toilet paper, the closer you get to the end the faster it goes". I'm a old man now but I've never got tired or bored with racing. Not many "hoorah's" left in me anymore. My joy now is to see young people like you do good and try and help were ever I can.

Hmmm...30" of wheel travel? That would be nice but I'm a ways off that. Probably have to increase track by a couple feet to get that sort of travel and still got the problem of a non-oscillating outer joint on the front to contend with. Only way I see is with telescoping driveshafts.
I'm actually increasing track by 4" before I build the new front struts. I'll see how much travel I can get using the Subaru CVs and swap to Porsche if I have to.
Tyres - Wrangler MTR. Dont know what I will use on my new 16" rims. Want to stay at 30".
Trans - STI 5 speed for now. Manual for now.
Motor is turbo 2 litre. Only 230hp.

I see you'll be limited to wheel travel. Most of the TT and Pro1's are mid-engine allowing long "A" arms for long travel. I use a Subaru inner CV and 930 Porsche outer CV. That gives me over 25 degrees deflection.
Goodyear makes a treadless tire that goes inside the tire. It wont go flat even when it's flat. The only thing that distroys them is rocks. We have lots of lava rocks and lots of sand.
You might later check into using a 4EAT automatic with paddle shifters on the steering wheel. Standard transmissions really take a hammering and the clutches don't like it eather.

These are the guys that do our transmission. Been using the same one for drag racing and off road for years and never lost one yet.
What EJ20 engine do you have? G, H, K or what? If it's a closed deck engine you'll be able to get all the power you'll ever need in a light brumby.
Do you have power steering?
You've got me looking for a Brat now. I want one to play with.
You know I expect to see you in the winners circle. I wish I was there to turn wrenches and watch you kick some donkey.

I get 24 deg out of a subaru DOJ. I havent measured a 930 but I just assumed they'd be more. Is this in your Super lite?

Do you have a link to these tyres? Flats are not something I usually have to deal with on Subys. I am more concerned with traction, compound & ride.

I must confess I don't know a lot about autos except that they are the way to go. I went manual on the preliminary build for simplicity and reliability. I have a trans here from an SVX which they tell me are the best as they have a constant drive pinion (?) as opposed to a viscous centre? Showing my ignorance here. It's a big sucker, bigger than the WRX box. I'd like to find out how to adjust the front/rear bias. I believe you need an aftermarket controller.

I havn't had the motor apart. It's bog stock, again for simplicity and reliability. It's a 1993 JDM WRX STI Version 1 so it's got a TD05 instead of a 4 and probably forged pistons but I doubt its closed deck? When I get the suspension sorted out and if I can out drive this motor I'll probably step up to something newer like a version 7 twin scroll with VVT. Good way to spend 12 grand.
Powersteer? Definately!

when you do go auto mate i will sort out a controller for your center coupling.. i will be knocking one up for myself soon

I can't find there tire liners. I'll keep looking for them

Thats close. I think it does the same thing. I've never used them so can't say, but your on the right track.

The motor is a G and is closed deck. Subaru autos are strong but power sucking heavy mothers.

If it's a "G" then he has the best Subaru ever built and the foundation for lots of power.
I'd like to see Brumbyrunner turn the gold into real gold and get some heavy sponsers so he can develop that runner into a bada$$ monster. If he keeps going the way he's going, he'll be hard to beat. It just takes time and $$$$.
Does the racing down there pay to win?
How long are the races?
What is the weight of the truck?

Brumbyrunner, do me a favor. Measure from the back of your cab to the center line of the rear axle and let me know how much it is.

First at the Finke is $10,000, places pay considerably less. Not sure about other races but there are only 5 rounds in the National championship so you gotta be in it for love.

Finke is probably one of the longer races at 480km (290 miles) over 2 days.

Not yet weighed it but hoping to be well under 1500kg in race trim.

Rear axle position is std Brumby/Brat. Was going to move it back but that would move my weight distribution the wrong way. Better to move the motor further forward if I need more wheelbase. Wb is currently 99" (same as the Forester). Trying to get the track out to at least 60".

I guess you have to be in it for the love. You guys need to get someone to push TV, Magazine, Radio and all forms of ad's and get sponsers interested along with the public. Between the prize money, sponsers and contingency money our racing is a business. I made 7 figures last year just playing. This year I'm more serious.

Anything under 500 miles (800km) is considered a sprint here. The San Felipe 250 takes about 5 hours start to finish.
The Baja 1000 takes about 18 hours.

The reason I was asking you about the distant from the rear axle to the back of the cab, our Trophy trucks are mostly mid-engine. That allows for narrow front and rear frames with long "A" arms for wider track and real long travel. Up to 36".
I've been trying to post a video of a long travel car so you can see how it works.

Clearwater99: I posted a airborne photo just for you. One of my favorets.
