lol,
Yes it all arrived, check valve fully operational and diode relay in operation, thank you very much for it all. Surge seems to be very little now, 1 barish at most on occasion. I also trimmed all lines to the minimum required.
I think the obstruction was caused by the lack of the O ring, allowing the pre turbo injector to pull oil and crud from the bottom of the intercooler where the post IC jet is.(crankcase venting prior to turbo, I have a catch can on my desk to stop this). It is also possible that it was polishing mop fibers from the tank that are probably small enough to pass filters end on, as they might be when in a flowing stream (like an eel
). I think it is most likely that I caused these issues, not your manufacturing!
Your injector calculations seem to be spot on, I replaced post IC jet with the 90cc (instead of the 120cc) by way of experiment (I must be getting confident, lol), and the MAT went up by at least 6-8 degrees on a hard pull! Needless to say I have returned to the 120cc jet. It will be interesting to see what uping the methanol concerntration a little will do after tuning.
I have gone through about 45 liters of mix so far! Definitely going for 205 liters of meth next time!
I'm really feeling ready for the tuning now and feel that I know the system enough to have a good idea when it is working correctly and what might be wrong if it isn't, the problems experienced being more valuable learning than if I'd got it right first time.
Cheers!
