Nothing wrong with humour Hayes .. I could have used a 'lil in my calculus classes when I began my math/CS degree 21 yrs ago .. talk about dry.
Rick, though my brain is smokin a bit .. and you made me pull out my MS Paint proggy and do some dumbass drawing to make sure I was on the right track before I posted the query, I forgive you ..
I just think it's really refreshing to actually get anything atoll in this thread.

Ty this thread was like passing a kidney stone, not that it's done we can more on.

It's not done, Sumo just hasn't logged on since last night....
For me I'm trying to work with the guy. I was following a SC cooling thread a while back and was a little miffed at how he handled himself there with all the "Been There Done That" engineering experience.
Honestly, if this was a few years ago I would have already pointed out that he's a Douche Bag and would have started to address him as DB by now.
But I've regretted that type of behaviour and not proud of myself in those situations so I"m refraining from that here.

Yes I'm around...
Did a quick read since my absence. I haven't forgotten the importance of it all (tongue in cheek). I've sent it off to two engineer buddies, one at Ball aerospace, one that teaches applied engineering here in chicago. I'm also working on drawing it to scale, so we can see what differences exactly we speak to. And just *maybe*, what rises from all this, is an accurate working front suspension model to use for our 80's (my primary goal in staying in this). Not sure I have a lot of interest in much else, given the digression of the thread.
I already got asked for the definition of articulation. The formulas I presented appear correct, so technically are the arcs (given the centerlines). There are several mistatements throughout the thread, and the initial feedback is that mine is ok as presented, albeit oversimplified.
This appears to have a lot of interest. I'll let y'all know what I find. I'm not interested in more flames...
As a side note, I went to the Chicago Public High School Regional Science Fair last weekend, at which several briliant young minds presented doctorate level papers with much higher levels of accuracy and applied physics than a bunch of 80 drivers could muster. My daughter btw, moved onto the Illinois Julnior Science Fair State Finals as an 8th grader. No reflection on her father, for that I'm sure...
Peace all,

We're crawling over large objects at the slowest of speeds, why do we need an accurate model. What would be the direct benefit of such a model?

As a side note - I doubt it. I have a BSME and have been making my living applying phsyics for a decade, and just happen to be one of the 80 drivers who you claim couldn't "muster".

As a side note, W.E., it matters not to me. My focus has been an accurate model of the 80 suspension during articulation. I will continue with that focus, despite of your colorful private emails to me.
I've forwarded enough information to get whatever input is necessary to move forward on this topic.
Thanks for your continued interest on my behalf W.E.

I'm convinced a few beers would have been the better 'chaser' all along.
Hayes, I been hounded by the best of the best. In the end, a working model of a 80 front axle during articulation sounds like a good real world goal for a tech list. I hope that the view count isn't for the carnage, but more for the possible tech goal.
I'll ck back in on this thread when I get the results back.

It would seem that Scott or QSHIPQ is a big fish in the Audi tuning pond. Alas, the pond has dried up, there is nothing but mud here and the fish is out of water.
Scott, as mentioned in other threads, nobody cares what anyone you know or what your credentials are. When you get your areospace drawings done work up some design changes and then come back here and post them up.
I'm sure there might be some things out there that nobody has thought up yet. I myself was told it was a waste of time making my own caster plates, it didn't stop me and I'm pleased with the out come and I did it with out all the condesending attitude you seem to bring here.

Nay said:The direct benefit is a clear understanding why you shouldn't do any of this to an 80.
More accuracy can be gained with a sawzall than any other equation

With 12 year old rubber bushings and tire wear and brand size variances vs actual "arc differences" , I dare say that might ultimately be the best conclusion Nay.

Sometimes we go on the hwy too
The best reason to have a good representation of the front suspension is to understand what our modifications really do and do not accomplish. Like when I thought that drop brackets maintained more consistant caster than lifting without them. That was certainly a good reason to consider them to me. Of course, after I drew it out, and found out it wasn't more consistent through the suspension travel, that took one of the pluses away from drop brackets.
Another is to show why certain parts are necessary when making mods. You can get a real representation of how much a lift changes caster (and estimate that doesn't account for vehicle to vehicle variation - someone will mention that
). Or you can show why with a 6" lift, the extended arms are really useful to put the wheel back in the center of the wheel well. And to make sure the mods your doing really get you what you thought you were getting. Like flipped arms, gets you alot of things, it doesn't get the suspension travel moving any more vertical than not. So if that was your reasoning for doing it, you know it won't get you what you want. ect.landtank said:
Again, I am only interested in getting a working technical model of the front of the 80. I'm no big fish anywhere. I'm a well seasoned practical engineer looking for thinking and application 'ouside the box'. As your caster plate example clearly demonstrates.
I was also told that I'd need to cut and splice IAC and WOT switch wires on my supercharger install. It didn't stop me from doing it without splicing either, and I'm pleased with the outcome. I designed and installed front airbags into my 80, and was pleased with the outcome. I might also mention, I did this airbag install as a relative newbie to the list, and got a 'worthless' ascription to the technical post, cuz it didn't contain any pics? No one is blocked from my view, cuz it doesn't matter to me the "who", I'm on several tech forums for reasons that have nothing to do with any 'person'.
Confrontation creates interesting conclusions of the written word. Few that share a beer actually find your conclusion of me to be true. I haven't been here long. I'm intrigued by creative engineering. I confront issues with a focus to task. My apologies in advance if you interpret that as condescending.
