I couldn't agree more... Brian's are also adjustable so I'm not seeing your point. Agreed' date=' probably not a huge issue. But I don't want any more caster change than necessary. I fail to see the advantage of the heim and combined with it being farther forward just doesn't excite me. I think were talking about the same thing... we just have different opinions. No matter how tight the clevis bolt is, there is no way for me to imagine that it wouldn't rotate with even a small load. I'm not implying "leave it loose". However, I think torquing it to oblivion won't do anything either. *IF* there is caster change during travel (from a non-ideal location of the rear pivot point) then I don't see how it could NOT rotate. The angles must change. So something either has to flex, pivot, or break. Its possible I'm looking at this all wrong... If you type REAL slowly, maybe it will sink in

...Point taken rt

Phantom nailed it... If you can't hook up, you can't break anything.

Sparky, Curious, did you play with the dimmer at all? Did it reduce the harshness any? TIA

Brian, I'll answer Jon, if I may... Trail has nothing, geometrically speaking, to do with with aligning the TC to BJ. The reason for the change is simply one less part to build, marginally less weight, and a slightly improved load path.

Damn... hats off to you!

Ballsy... especially on a combo machine

Rob, Nice job. Regarding your slot finish... are you climb milling or conventional?... Can make a heap of difference in the finish.

How does that *open* a gap?

Look'n good, Brian.

I'll second Jon... It would take a preload setting way beyond usable to expect the car to move about on one axle.

Sam, I respectfully disagree. The ground strap, if the proper heat range, will indeed run hotter. Taken from Champion spark plugs.... "If you make modifications such as a turbo, supercharger, increase compression, timing changes, use of alternate racing fuels, or sustained use of nitrous oxide, these can alter the plug tip temperature and may necessitate a colder plug." Also, the way I understand choosing the right temp range is shown in the below pic... This clearly illustrates the ground strap running hotter. Twenty bucks says Braap is right

That should be the Jeff Hartman book... If so, its a good read.

Hi, Its located under the dash, nearby the steering column. It looks about the size of two standard relays side-by-side. It has two plugs attached to it (becuase its actually two releys, main and fuel pump) If memory serves, one plug is black and one is clear. HTH

I can only assume you're addressing me. I agree that you have an issue that needs resolution, but I also think its a terribly small representation of the big picture. I don't believe you can say that you have laminar flow or a propensity towards equal cylinder filling when your test's only show the static picture... too many other influences. No doubt, its a starting point and I appluad your efforts. However, once you show static flow to be acceptable... your work has only just begun. Of course, this is just my opinion... I could be wrong

Mario, I think even capping them would fall short of whats really happening. Keep in mind, every time a valve closes, it sends a pressure wave back up the runner. Theres only one valve open at any given time, so the 5 backwaves could have significant influence on whats happening in the plenum.

Yes, TPI is typically 40-42psi, 280Z typically 38-40. No worries. There are plenty of vent lines in the 240 tank to get fuel back in but, you have a bigger problem than that... if you do not run a baffled tank or some sort of swirl pot, you'll uncover the pump pick-up under accel/deccel/cornering, causing very unpleasant surges.

First, The 280Z's fuel pump is external. Second, I would assume you'll be using the TPI Fuel press. regulator (mounted to the pass. side rail, aft) so no worries on proper fuel pressure. Third, I once installed a '75 tank in a 240 ('77-'78 are larger) and it 'sorta' fit. The thing that I remember most is that the strap 'embossments' are in a slightly different location, so the strap brackets required some tinkering. Looks a litte funny as well. HTH,

What are cfds? If its not too much trouble, I'd be interested in seeing a video of one port open at a time. Is it reasonable to 'cap' 5 runners? It seems this would be a better reflection of reality. Thanks.
