OMG this is like NEVER going to happen. The latest plan is thur or friday sometime. Maybe this weekend. Sigh. The worse part is having to store albert's fuel rail for months while he's gone, and I only get to see him on those awkward mornings where I don't leave his mom's room until after he's up - and I'm still in my robe.
I mean Thanks for lending me the injectors!!

Has anyone put a wideband on all cylinders to prove this? (NA only) or is this all speculation based on dead number 4 cylinders? If the latter, take careful note that your coolant goes in the front and out the front (unless you modded it and installed a FWD head gasket) thus doing it's best to miss out the number four end all together. Mazda *try* to compensate for it by enlarging the holes at the far end and closing them up at the close end, however it never works as well as it would with the FWD setup. Miatas are not alone here, all mazda RWD setups are this way, and they all suck. If someone did put four wide bands on their NA bp/b6 engine and prove the flow thing, what I have posted is still true and good to know. If they didn't, I'm placing my bets on that! EGT alone is NOT good enough to tell you the answer to that as cylinder temperatures do affect it.

It'd be worth doing this test twice if the second time I had an NB rail and a pro dual-feed rail.
Right now the plan is: Leo brings me the boards tonight
Tomorrow night I get stinking drunk watching movies and playing video games
Saturday "morning" I do this test come hell or high water.

Abe, are you going to run the test with the second feed blocked off? If so, you should minimise the length of hose to the blockage as the stretch in the rubber will effectively dampen the pulses and potentially skew your result lol.

Thank GOD someone else sees that. :-)
I wish I had an unmolested rail to test with, but beggars can't be choosers. Right now I'm thinking I might try to plug the hole with rubber or a very short hose... But I'm also tempted to tap the inside of the brass fitting, thread in a bolt and put an oring on the head - that should give it a metal, non-damping back to the rail.
'Course, maybe braineak can chime in here....
My biggest questions right now all revolve around the stock rail, if the stock rail works perfect, there's no need to look anywhere else.

I swear, at university, i didn't learn about physics, chemistry, calculus, computer science etc, I learned how to apply thinking :-) IE, always be critical and analytical. I appreciate that quality in you Abe. You are like that song by king missile :

Then I'll be on here begging someone to send me one of these fancy rails. I'll test a dead stock one, an aftermarket one, a home mod one, and maybe (such a PAIN to pull) my '00 stock rail all side by side.
So, in short, not right now, but maybe. And I do, I might be begging you to put off installing your new rail a bit. :-)
As a personal favor, if anyone has a '99+ stock rail, I'm interested, since it's what's on my car, and the only bit of this that really pertains to me.

God Dammit!!!! I and anyone else waiting for results just missed out on the $99 intro price on those new rails. AAAAAGGGGHHH!!!
Science and reason just cost me another $20! Guess now the pressure is off to get this test done since they are regular price now. Still look forward to seeing the results!

PLUS like everyone's bailing on the san diego scene so... No luck yet. But either this weekend or wed/thur night. Really looking forward to doing it... Just not to playing camera man AND running the test. But I got all my boards back, and Leo's car's all up and running, so I should have ten minutes to myself now if work ever slows up.

Heh, yeah - I can't seem to get two people together at the same time to do it. Now the girlfriend wants her measuring stuff back and another forum member wants back his injectors - I can't blame them, it's been too long. :-\ I think it's just something which would go a lot better with a second set of hands.
Anyway, thur is the big last day, so there you go.
