Brian, I can't measure fuel flow on boost. But on boost I am at WOT. To get the first fuel flows, I simply depressed airplate to near full extension. At idle I just cracked it open til fuel flowed. Your comment is interesting. I last had the headers off when I re- ringed the engine about 3 mths ago. 2 & 5 were looking the leanest - but the WOT fuel mix I recorded this time was almost identical to this one. I made a small tweek back then to get them even, and that is how I now record them. I have generally put 2&5 down to running hotter being mid cylinders, but you are probably right.
But I am truely baffled by this result. There are defintely no air leaks in 1-3. I think I need to have a look after taking it straight off the track with no cold running/idle. But even the idle fuels don't/can't explain it. What I'm trying to figure is whether this is in any way indicative of my track conditions.
One other thought was the over-run. I have 3 ft flames out the zork when off WOT and on to brakes. I can understand this (CIS - full fuel mix in intake), but why only one side?.
Waiting for your headers - which is why I have these off.
