Definitely staying with a more scale/realistic power range on this one is the plan.

I'll throw the frame on the scale tonight and post that up. Hoping to get a chance to clean up most of the welds tonight and maybe get to working on links.
 
"1000 horses is the new norm" isn't that the truth.

these new breed of 1;1 rock bouncers are running quite a few ponies.

if you scale 600 hp down to 1/8 scale how many watts should you be pushing?
 
maybe itl be page seven ounce the scale horsepower figure is figured out.

not sure but I think 75 is 1/8 of 600???

by the name of Harleys thread im thinking ramjet 350 as the 1:1 power plant so maybe if mildly built were in 300-450 power range wich would reduce wattage number. ill call it 400 horse be back with wattage number

coming up with 50hp. they way I see it is is he cant be over powered and be in scale type power.
more then likely he wont run a 1/8 scale motor so will be inside 3hp

I do know if I had that much money in tubes and tools to build a 1:1 cage like that, that id probly also have a healthy mill on the nose.

I'll probably run the stock Axial foams which are SUPER soft. With the stiff tires + a 10lb rig + very little foam support that should equal a tire that will squat decently when it hits a rock but stands up when spinning.

All theory at this point...

Are you going to Tennessee cut the tread like TC? Removing every other row entirely for some real diggers.
 
You should run a 6s system so you can do 4 wheel burnouts like the 1:1, LOL! Just kidding, Can't wait for this build!

You can't just divide the power rating. Scale weight is cubic and the easiest way to try and calculate an accurate power figure number would be power to weight.

The real truck was running somewhere around 500 HP I read, who knows how true to life that is and how much beer drinking dyno talk was happening. If you compare these trucks to Ultra4 cars that spend more time on the Dyno, it has been shown that the drivetrain in these types of trucks can soak up damn near 50% of the power (reading on a traditional dyno which is hard to equate since the huge heavy tires can throw stuff off).

I would say that the fullsize truck probably is anywhere between 10 and 15 pounds per HP.

So I would need somewhere in that .75 to 1 HP to be realistic. A typical 35t motor at 12v is somewhere around .5 HP. Hopefully these Crawlmasters or TTC Puller get me closer to that .75+ HP rating.

Enough of that! :mrgreen:

I'm going to head back down to the shop here in a little bit to keep cleaning up the chassis.

But this rig was only running around 500 HP from what I've seen.

Power to weight speaking, I'm hoping to be close to the correct ratio when its all said and done.

Your right about his hp range I was just givin you a hard time about the 1000 hp deal back when I was getting parts together for the 1:1 I almost built ( long story ) I was looking at building a f2r procharged 460 ford I had everything but the efi and had to part it out to pay bills and get me out the hole I dug while on wc. It would have easily pushed 1000. The main point is build it how you feel you need to build to make you happy and comfortable on the trails.

I knew you were just razzing me. I was just making excuses to not run more power right now :ror:
 
Yeah more is not always the answer but it does sound real cool when you're drunk and running that mouth. I think I'm going with that new big outrunner holmes has got since mine will be considerably heavier than most.

You say that like you think the Rc tires and drivetrains don't soak up as much.

So we need real Rc dyno to read off the tires.

Good luck with your build

RX8 and brushless is so unscale... You don't need all of that.

and for the record, this buggy in real life is driven by Trenton Parks, not Tim Cameron. Its built on a budget. it ran a 6.0 LS that is actually under going an engine overhaul and will be a stroked 6.0LS.

to be SCALE... a 2 speed is required. These buggies mostly run in 2nd gear when they are slingin shit. That's why you see Tim Cameron or other guys walk up something the first couple of times before they hit it. 1st gear to see how it reacts, back up far enough to throw it into 2nd and release the horse power.

Throw something in there and see what happens. I personally like brushed better because you can always rebuild it or just swap something else right in. Keep up the good work Josh "thumbsup"

So what is this buggies setup then? 6.0 lS, Turbo 400? transfercase? Looks like 14 bolt axles right?

Looks good harley cant wait to see something like a puller motor in that, should be the best combo:twisted:
