Happy Labor Day!

The [deleted] Republicans can [deleted] their [deleted] and [physically impossible] their [deleted] today. This is the day we celebrate the little guy, the guy that does the actual work that makes the 1% rich.

Before I forget to censor myself let’s change the subject. I have been looking at pictures of the cylinder heads for the 3.8l V6 and I noticed I’m going to have a spark plug problem, on two fronts. First problem is the spark plugs protrude into the combustion chamber exposing threads which could cause pre-ignition when I shave the head for higher compression running E85. And speaking of shaving the head the other problem is the tip of the spark plug will get hit by the top of the piston after zero-decking the piston and shaving the head. Throw in the fact that I will need to run a different heat range of spark plug and that means everything about the plug has to change except the thread diameter and how it seals against the head. That means physically taking the head to the parts store and threading plugs in and out to make sure I don’t expose threads while using an extended tip to get the spark plug to get the spark as close as possible to the center of the combustion chamber without hitting the piston. Sounds like fun in a box!

And in spite of what you just read I’m not an engine guy, really. My specialty is suspension design. And being poor, I’m pretty much a master at being poor. But there isn’t much design work to do with beam axles on both ends with 4 bars. The main thing about this suspension design is the springs and shocks, and with the pull rods at the rear I don’t actually have to change anything except the links between the axle and the rocker arms to go from street cruising to full race set ups, meaning I only have to change the front shocks and springs and those links at the rear. And I only have to buy front shocks and springs to change from street to race, and those may not actually be any different except the spring height setting.

That’s part of the beauty of pull rod suspension, the spring rate and damping change how I want it to, and are always perfectly matched to each other once I get the spring and shock matched. All I have to do is change the ratio of the bellcrank arm connected to the load (the link connected to the axle) and the arm connected to the coilover. I have an infinite number of rates from too stiff to too soft by huge margins just by drilling 3 holes in a triangular piece of steel or carbon fiber sheet. And I can change ride height as easily as I can change the toe setting on the front wheels.

And since I want to get this posted while it’s still Labor Day…
