Mini sand dragger

[Bugpac]

Both drivens on a common shaft....

Weight? He's gonna fill the frame with helium. Kill at least 100#'s right there!

[SPEC]

he he he

[fabr]

Helium,hehehe!! An old myth that SOUNDS reasonable.

2 tripples...
That would be interesting to see, synchronizing 6 carbs could be a challenge, 2 Identically set up CVT's should be doable. into a single jackshaft, then to the chain. you might want a chute on that

Bug,
I got 2 tripples...I'll tradeja for the drak ...Not...That would be interesting but prolly not practical...CBR 1000 with a CVT would be tho... where is sideline sal when we need him???

Just something for you guys to think about here.Drag racing demands consistency at the tree.I think that a cvt will be a lot more inconsistent as compared to a clutch at the line. If you're serious about a sand dragster I'd do the superbike engine route or just go full size with a powerglide and a tranny brake.

You could have both drivens on a common shaft that goes into a rear diff for no chain. My concern on that if using say a 1" keyed shaft, I don't think it will hold up on the back side of the second clutch where the power of both engines is on it. You might need chains on each side going down to a second shaft that is thicker.

I was talking to someone building a sand rail with a highly modified Mercury V6 2 stroke. He welded in exhaust bridges in order to support the rings with the widened exhaust ports. He had to run a jack shaft along side the engine that took power from the front and brought around to the back. It would twist up cranks trying to take all the power off one end.

The Supercase engines with 3 or 4 CR500 cylinders have a jack shaft with cogged belts between the cylinders.

Whooooaaaaa! That's cool. I'm curious about something though.I've got tons of 1/4 mile dragging experience but none in sand.My question is this; are reactions given and if so how consistent are they?

Thats the problem, you think it will be...

It doesnt seem much different than ashphalt, except your throwing a roost...There is plenty of guys throwing down, .005

[borris]

Guys with CVT's are cutting 005 lights with consistency? Do they give 60' times? Are they consistent? Educate me.

[Bugpac]

At bobs i was cutting very consistent light, they were a little slow as i learned is likely from car reaction, but they were extremly consistent...the sand in general is very consistant among the other cars i do know that...
