Another theory that we discussed on the day, was whether we had an injector problem, and that one was either blocked or malfunctioning. I'd hope not, being Injector Dynamics ID1050X's, but everything needs to be checked.
Upon getting the car home and leaving everything for a week or two, I then removed the injectors and took them back up to Northampton for them to run on their ASNU injector diagnostic rig.
Just one of the many tests that were run....
'Scuse Steve's mathematics error, lol....but the results we got from the various tests:
The results, I have to be honest, were underwhelming, with 5.7% variation across the set of six injectors. I'd be satisfied with that for randomly manufactured, off the shelf injectors, but for the level of care and attention that I know Inj Dynamics put into their manufacturing, I'd have expected a lot closer spread. Of course, I've liaised with their support team, who said that a) there must be blockage due to unsatisfactory filtration (again, a brand new FueLab 818xx series filter was installed), and b) were dismissive of the ASNU test rig that Northampton Motorsport were using.
I do now have the original check sheets for each injector, but not had time to read, understand and correlate them to what we saw with the tests. At the moment, the offer is there from I.D. for me to ship over the injectors for them to test (f.o.c) and clean if necessary....
In honestly, I don't think this is the root cause for any of the problems we saw on the dyno day, but it's interesting nonetheless.
