Title: Arley Langlo, new streamliner
Post by: bvillercr on April 23, 2008, 09:30:45 PM
As you can see this is the early stage of his build.  I beam for accuracy.

wheels and tires.  Rear tires are 30" Mickey Thompsons.


(http://i162.photobucket.com/albums/t246/bvillercr/IMG_0146.jpg)

I believe he will be running multiple size engines, a 260 cid, 300 cid and maybe one of our 500 plus engines.

Dual rear ends.

Not sure of the type of rear end they are.  The forward tires will be wider than the rear tires so the body can tapper in at the back.

     I took these pictures when i was in Santa Barbara last weekend for a family reuinion.
     The rear ends are champ style but made from solid billet aluminum by Brian Gary son of Pat Gary another landspeed racer. The 33 ft. long I beam comes from Seth Hammond's shop.
     Arley is having a hard time getting the wheel manufacture to start on the wheels,same on special shaft connecting the rearends. One time deals you know.
      Avery Galbraith and Jim Wilson an aerodynamist are working on the body shape. they have a high dollar computer program they are able to use through a special deal.
       Anyhow a lot of work ahead but Arleys wanted to build a streamliner for 30+ years.

Thanks for posting the pictures.  The rearends are a piece of art. 

I wonder about the reasoning behind the two rearends though??  I can fully understand 4 wheel drive (front/rear) on a streamliner and can see it is the only way to go for speeds over 400.  With it all of the cars weight is going into providing traction.  With the 4 wheel drive only in the back it would seem that you are only still using the weight in the back half of the car and haven't really gained anything.  I'm probably missing something here.

Keep the pictures coming,

Sum

I remember a dual-hemi-engined blown fuel Messershmidt (sp?) Comp Coupe at Bakersfied in about '59 with tucked in rear ends -- the narrow in the front, though.  Perhaps he could find another I-beam and use them as frame rails?  Lotsa traction there!

There is a curve in traction vs unit pressure . 4 tires with 400# each have slightly more grip than 2 with 800# each .

I could see that being an advantage, but how much and vs. if the other two were at the other end of the car.  I'm not trying to second guess the builders as I've done some things myself that others don't agree with, but I'm trying to figure the whole deal out better,

  Arley and his tuner Jay Roach wants to wait on pictures untill its done. Big suprise :roll:

i'd like to know if it is 6-wheel-drive or 4?

flat-sided?

  Hi Rob

  This is what my cousin Arley is doing to increase traction

  Arley has the frame and front axel almost done and the shaft is made that connects the rear ends.

Can you tell me more about this traction curve? How much more grip will the extra tires give? Our rear tires (only drive wheels) have about 1400lbs a piece on them now. Would it be any traction advantage to running them slightly offset from the other set of drive tires even though it would be less aero efficient?

That was the Colburn Glaze car,comp. coupe. But others have tried it as well. Les Liggett was going to build a liner several years ago with the same concept.

  Why not a more high tech wing that produces more down force with very little drag? That way you don't have the loses of an extra diff and 2 tires yet you still have the down force neccessary to go say 386 like MR Fast Freddy.

  Double the contack patch double the traction and I have been advocating variable pitch wings for years. Arley's aero guy is working on a wing type also. High tech wing sounds great getting or developing one is another.

I was thinking about that traction issue, and wondered if running a flat crank wouldn't be to your advantage?  Honda won several world motorcycle GP championships by stagger firing a V3 2-stroke to get uneven torque input events to the drive wheel.  On the really slippery tracks they had the option of firing all 3 cylinders together!  They also learned that you need to fire like a Harley, if you want to beat a Harley coming off the turns on dirt tracks.

Big traction improvement, there.  I think they already make these cranks/cam setups for Sprint cars....something like 2 cylinders together, then 2 in a row, then a different 2 together, then 2 in a row....kind of like a weird 6 pattern.

Interesting project...fun to read about and thanks!!

....or you may need all 6 AND flat crank firing!  This sounds like a pretty big power project!!

 Yea Jim ... theres a lot to learn about traction in LSR. I mostly raced off road desert but I got real frustrated in a motorcross race trying to pass a Husquvarna in the turns on a sandy course when he would just pull away when I was just spinning my tire. But this was due more to suspension setup than firing order.
  I'm looking foward to the new Hebert streamliner as its fully suspended and the crew chief knows all about spring-wheel rates-suspension points and how to make adjustments.

There ain't no f'ing sidecars in Arlies life.

They come from the same zip code.

Cmon guys. Anymore info on that traction curve? Is it really double? I wouldn't think so.
If it's over 70% more, I might be calling Timney tomorrow to order another Extremeliner. I would also think that each one would only have to take half the engine torque. I am concerned about breaking ours as we are over 1500 lbs/ft of torque.

  Whats an extremeliner? There's several books on handling and tire traction curves my favorite is Carroll Smiths book ''Tune To Win''
also Herb Adams ''Chassis Engineering'' The trouble with Lsr is that not a lot of people do it so not as much is learned as in other types of racing. We built our AA blown gas altered 20 years ago and just a handfull have been built since then,same as in A to E. Not much competiion to learn or get pushed foward from.

Extremeliner is the Winter's quick change that we use. I like doubling the total contact area but I'm new to this salt stuff and things that I would think would make sense may or may not work.
