Pics of assembled s13 adapters - review before panicking!

Angry bench racing hahaha

look how many things were designed in reality only to succeed.

from flat head fords, to push rod fords to rocker arm and finally cam on bucket now today to electric solenoids that open and close intake valves on the 370Z.

from steam engines, to gas, to diesel to electricand hydrogen.

carbs, throttle body injection, side feed fuel injection, to feed fuel injection, and finally direct injection?

what do all these have in common? when first thought of they failed.

where their failures? of cause but failure does not mean it wont work failure means a method it will not with with much like the S13 front suspension, we are achieving "bolt on coilover" thing here with out all the inherent flaws such as SAI, scrub, caster, camber, roll center, ackerman angle so on an so forth I already have money down on this setup and believe it can work.

jesus tap-dancing christ, now we're discussing the history of everything in a thread about designing a coil over adapter in relation to how many other things have failed in the history of history…

welcome to z31pessimism.com

First of all… electric solenoids do not open the intake valves on the 370z or any other engine that works (well). VVEL is purely a mechanical in operation with electronics to adjust it like VVT.

Also, all of those things you listed did not come about by engineers do things such as… "well, we have all these pushrods laying around, i guess we will do that instead of overhead cam"

Most new things do go through trial and error. Design and redesign, true.

But that is not the case here at all, this is sticking a round peg with a shiny adapter in a square hole because you have more round pegs than square ones.

You said it best your self. You believe is can work. I believe it can work too. That doesn't mean it will work well, or it is the best way to do it. It certainly is not a flathead ford, or VVEL, or any innovation. It is more like using scraps around Apollo 13 to stave off carbon dioxide poisoning. It worked. Great. That was not the new apparatus to be used in all future spacecraft.

can we start a new thread and try this shit again?

why the fuck are intake valves even a thought in this thread?

Says the guy whose previous post in this thread contained only a gif animation of something totally unrelated…

Glass houses man....

So has any more progress been made on the napkin physics front…?

Or can I say things like a 6k coilover spring will be close to twice as stiff as a regular z31 spring… or how about the fact that on a lowered car, moving the tierod pivot up by 5mm results in more like 1mm of lateral movement.... or how about the coilover mount having a 6:1 ratio of compression to lateral motion, which when reduced by the lever distance becomes closer to 20:1

But go on tell me how 3mm will totally screw up your car…

That "could" is dependent on a lot of things

I'm just going to say, that I think it is highly unlikely that it would be enough to cause wheel hop on braking, just an undesirable side effect to be aware of. I haven't been following closely, what is the problem with running them straight?

Straight requires putting the mount outside of the z31 strut tube to place the body inline… that adds way too much cost for what this is supposed to achieve

So doing it like the s13, the only issue is the tilt of the mounting bracket and strut tube angle don't allow the exact same strut top location the way I designed the prototypes… the "version 2" will allow you to adjust it, but the axis of motion will be s13-like not z31-like.... some people seem to be deathly afraid of this fact

Ah yeah, I see. Tough one. If it was me, I would want to move the pillow ball inbound as much as possible, run it out of "perpendicular" by changing the angle and deal with a little positive change to camber gain and run a bit more static camber. Lowered Z camber gain sucks to begin with.

Following thread,

Well obviously a person getting s13 coilovers can choose to get some with camber plates, but as they just require a little drilling, the plates can be oriented in any direction; then you can rotate the s13 coil to sit behind or nearer the front of the spindle, and use a rotated camber plate to lean the upper pivot towards it

For example, even without camber plates, by mounting the s13 coilover behind, you rotate the spindle forward, then use adjustable tension rods to pull the bottom forward un-rotating it, you can maintain camber and caster

If the coilover is mounted entirely inboard as in the case of the s13, you may or may not have enough camber plate adjustment to give yourself the setting you want, but my final version will allow the mount to adjust static camber as well, so you could increase the camber at the mount, and decrease camber on the plate, this lets you have increasing camber in the turn without looking like a dork driving straight

As someone once said, you can't give z31 owners too much choice, or their heads explode, or something… (I'm paraphrasing slightly)

My flawed design? I didn't design the offset strut mounting system, go send your nastygram to nissan please
