Well, I haven't fallen off the planet, just never thought that anything I did was enough of a milestone to write a comment, or when I did, I didn't have my phone with me to take a picture.
I got the car supported on its own suspension, so I figured that would be enough of a milestone, that I should come post.
in no particular order, (and I couldn't tell you the order I did them anyway) I've completed:
Built my megasquirt, hooked all the sensors and control circuits up, and it can read everything and control everything. I didn't fire it up, since I had no exhaust, cooling or fuel tank. The latter can be done with a fuel jug, but the rest, I should wait. This was a whole lot more complicated setup than the m10 that used EDIS for spark control. I added a few extra features to use up all the extra IO on the board. Fan control, launch control (hold at x RPM until deactivated, which will be one of the factory clutch switches), shift light (spare output, may be repurposed) and some other input that I can't remember now. Hopefully I left good notes for myself
Something I discovered using the Stim (emulation board), launch control won't activate if the RPM's are at 0. Makes sense after I discovered, but that caused an evening or two of grief trying to figure out what I had done wrong in my setup, which was all fine.
all control arms. Used material that was thicker than was probably needed, but rather have them heavy then bend. I have thinner material, so later I could re-make.
changed the diff angle position device. From the bottom of the diff, I ran a tube and a couple heim joints to a bar behind the diff. I figure late model stock cars use a bar going forward from the top of the diff, so this is about the same. I don't think I have a picture of this, so maybe later.
shortened the drive shaft. The shop I talked to, won't/can't work on them as the material is too thin, and the ends are friction welded on. THey could make my one, but the price was $700... nope. I see there are aftermarket folks that make aluminum ones, for less. I'm sure they'd make a shorter one for the same price if this one doesn't work out.
after all of that, I decided I may as well do the squishy stuff on the corners. I looked at getting QA1 dual adjustable shocks/springs, or the Jeggs ones that look like they are just re-branded QA1. After looking at the rear, I realized the only way I could do that was to do inboard shocks, unless I re-did alot of work, so I decided I may as well do the fronts as well using inboard. After all, we're not doing this because it's easy. After a few test parts, testing, measuring, calculating, I came up withe the front design and cut them (I built a plasma table some years ago, so that makes prototyping and making parts a little easier) I settled on 2003ish GSX-R 1000 shocks, as they have the longest throw (~3 inches) and a decent spring (~450ish lbs/in, or close to that) I figured with angles, different length sides to the bell crank, and some angles, I could get them close to 200 lbs/in in the front and 150 in the rear for the effective wheel rate
Summer flew past doing other thing, and that didn't happen as fast as I had hoped, but last night I was able to suspend the car on its suspension. Wheels on the front, lumber on the back. I think I have to make the center on the rear smaller and the push rods longer so I'm closer to 45 degrees between bell crank and pushrod at full droop.
Anyway, enough blathering, time for some pictures.
