Basic Dwg. of chaincase idea......Whataya think?

[Whiplash]

Here, see what you think......Here is a quick design I made for the above Idea, basically its just a housing likely out of steel for now and then I will make it out of Aluminum, CNC'd once I know it will work. I plan on two 530 chains on matching sprockets inside, and running them on 1.5" o.d. shafts through carrier or pillow block bearings on either side of the case, what do you think??

looks good, but timing two chains and adjusting for stretch is not likely do able... why not use a 530 2 row chain?

would two chains wear alike, and what if timing of the sprockets was one degree off, what chain would do more work? why not a off the shelf silent chain?

[Boostinjdm]

My theory is that after a break in period, the two chains would share the load.  if you use two off the shelf sprokets and bolt them  on with the same bolts, they will be in time.  if they are off slightly, one will wear enought that the other one takes on the extra load and from then on the load will be distributed evenly.  As for the silent chain.....cost.

I would have to agree with Boostn, the two if installed new would wear in together allowing for even distribution since one would stretch then the other would be forced to do the same....or at least that's the theory....

I also agree, I am working on a new dual chain setup and I was concerned in the beginning about one stretching more than the other, but if you think about it, one chain can't stretch more than the other since it has to pull on the other chain at the same time, so right after break in, I think they would have the exact same amount of slack as one another.  I'll be running dual 630's on my setup...

What in the hell makes enough power to need twin 630's?

What i'm doing may actually need 3.....

NO SECRETS! Lets see it!!

Plus, with the typical power plant, you will likely have less stretch than usual as well due to the higher total strength of the two.

2- 100 dollar chains 4 sprocket mounting, i have to imagine a 2" silent chain off the shelf with gears splined would be cheaper, and much stronger IMO.. fabber has all the contact info, may be worth looking at...

[Yoshi]

[Admin]

yes, but the design of the silent chain makes it stronger in our application than a standard 530 chain... maybe not tensile strength, but in the real world... fabbers car was a 3" i think, maybe 4, new design is 2, fabber offer your wisdom here...

I guess Yoshi gonna put 18" wide slicks on the nitrous/turbo busa powered smart car??  Its just gonna flip over backwards, probably should go ahead and put wheelie bar mounts on frame while your welding.
