Thanks for the info. We will be building for the mile, so light weight for faster acceleration is the goal. It will be difficult, because I usually build heavier than needed in my motorcycle frames to make up for my engineering ignorance.

Randy, you will be geared a lot different.  The Bockscar will not move itself from a stop, it requires 25 to 30 MPH to pull on its own.  It will spin the wheels at will in the first 2 gears... get into 3rd at about 140 MPH, will still spin the wheels if you are not carefull.

I hear ya, trying for top speed in the mile will be much different gearing than the salt. At least traction shouldn't be an issue. There was a really sleek looking lakester at Maxton last year and I think it was running a 750cc motor. It looked like it was built pretty light, I'm gonna have to see if I can find it in the run logs. I think it was #326

look like this? RTR's picture... It is a nice car.  Was for sale for way less than build cost in the for sale section

That looks like it except for the color, it may have been different color when I saw it...or that's just my CRS kickin in tongue

To me...half the fun is building a car or bike I could race, I just couldn't bring myself to buy one because I would have to take it apart and put it back together. Of course, if I found one that really floats my boat, I could change my mind.

I found the listing you were talking about in the sale section, It looks like it's been the same color, did I mention my CRS shocked LOL. That's definitely a high dollar, high tech build. I'm hoping for a lot less than that in the build. Since Joe and I will do all the work and fab ourselves, we should be able to keep the costs down.

Randy, as promised earlier I took some rear suspension pictures.   There is a lot of stuff in there, but I think you can see how we did it.

Stainless that is very nice!! Great fabrication  smiley.  I don't think I've seen it before as when I was by the car I think the body work was on back there,

Here's a few more, as Sum said, it is hard to see when all the body is on.

We ran a panhard arm on the 4 link for several years and several spins before we changed to the triangulated uppers.  when we put in the panhard, it was very short about 18 inches and we were unable to make it parallel to the ground without interfering with the axle.  We made too many comprises so the suspension movement caused a little rear steering.

The triangulated bars mount at the same level as the top links, otherwise it would bind.

Shifting by air, up and down...  grin
There was a time we had cable shifting, to hard to maintain.

Great pics Bob, thanks. It looks like your axle is a 3 piece set-up, is that correct? Does it come apart easily for a gear change? I believe I see what looks like 2 couplings outboard of the center section with a thru-bolt in each one.

Yes you are seeing that correctly, it is a 3 piece straight axle, there are 6 pinch bolts, a 1/2 inch key and the thru-bolt is there to ensure the axle is retained.  I would like to say gear changes were easy, they are not hard in the shop when the car is already apart, but a little tougher on the salt.  The new trailer will make it easier, we put a support under the flat part of the car for jacking and tested it on the salt. 
We have used split sprockets in the past, but keeping them aligned was a problem even with precision bolt holes.  The sprockets are 1 piece now and we usually make our first gear change at the front.
