flatout

very cool, Nothing wrong with an old machine if its dialed in right and run by somebody that cares to make a good product. I run a small machine shop from my garage, just not engine related machining. Sure you could drum up some work for those machines.

I did a 14 gallon radium cell in mine because i plan on possibly running e85 and we have some 30-35 minute sessions with some clubs. I have it raised like an inch and a half out of the floor to make the bottom height where I was visually happy. My cell is advertised at 11.7" tall so if the ATL 10 or 12 is shorter then flush with the floor should be perfect.

I just found this site as i started building my Z, and will be following along as you finish up this project. We are on somewhat similar paths so this will be fun to watch it come together.

Lower than 100kpa at WOT could be elevation too, if this log happen to be somewhere higher than your used to logging take that into consideration aswell. Id think where you have the filter should be a good spot for air. unless the aero is really creating a negative pressure spot for some reason. If thats not the case id think your on the right track with looking at valve train stuff. But don't rule out the sensor itself or the hose feeding it.

What transmission are you planning on running?

Did you end up purchasing the parts? With black friday sales I was considering their rear control arms. I don't love having a third heim that can wear out compared to others but i like the triangulated design and the motion it allows. As far as the shipping. just the control arms are like $60 to ship inside the US. can only imagine all those parts crossing the ocean would be costly. Maybe the kit comes assembled? would be weird but possible.

Love to see the scans and some thought behind the design. I was thinking the same thing about the limited motion of the apex shock. My car came on a set of coilover struts that has similar travel so i've been looking at options. If you need any assistance with CNC machining, I may be able to help out.
