Sprint car build thread.

[racrguy]

What do you need to get a sprint car on the ground? You need the chassis above and all the parts below that I'll list out.

First off, the whole shot:



Now for the smaller close ups, starting from the front of the car:



In that picture is a front axle assembly, RF torsion arm, LF torsion arm, 2 torsion bars, 2 torsion bar stops, 2 shocks and 4 radius rods with heims.

In the center of the car:



Here you have a drag link, pitman arm, steering gear and reservoir, rear motor plate, torque ball and housing, a shifter and a master cylinder with residual valve. (you can see part of a torque tube at the bottom of the picture)

Now a bit farther back:



Here you can plainly see the torque tube and rear end, it looks odd, but you'll understand how it all goes together later.

Here's a picture of the driveshaft, which I forgot to lay out. Have I mentioned titanium stuff is light? The only steel part in this picture is the snap ring and the swivel splined portion to the left of the picture, it slides over another splined portion of the driveshaft so it can be replaced when/if it wears.



And now for the rear suspension pieces:



Here you have 2 more torsion bars with stops and arms, a couple more shocks, 2 more radius rods, bird cages, which are the rear suspension attachments that double as wheel bearings, a right rear brake and caliper and the jacobs ladder, also known as a watt's link.


As of this moment the car is on the ground and I'm going to write up another post tomorrow, time willing.

I started this thread in the corner carving section of the boards, but then it dawned on me. Most of the people that visit there are already into racing, so I need to post this in a section so that people who don't know squat about dirt racing, or sprint cars specifically, can see what goes into one of these machines.

I'm going to take you from this:



To this:



All of the measurements and whatnot have been done already, and all the plumbing set, so I won't touch much on that, but you'll see how one is put together.
