Got my vbox data sorted out from Santa pod
my box was consistently showing 1 tenth slower and 1 mph slower than Santa pod timing gear for all 3 runs I recorded

Forgot to turn it on for my last 10.3 run as was thinking why couldn't get full power and forgot



Fastest 0-60 was 3.5 seconds I've done 3.2 up my road so I assume the extra grip was causeing some bog so should definately take more rpms at launch

First 10.6 @ 148 mph run is the red plot cal 3 so about 1.7 bar roughly from 3rd gear lower boost in second

Second run 10.1 @ 142 mph is blue plot, cal 5 so about 2.2 bar roughly was pulling really strong into the low 100 mph and felt it drop off, that's when inlet popped and can see it fall on it's face in the curve (didn't know at that point inlet had popped)

3rd run green run 10.9 @ 141 mph, was cal 8 full 2.6 bar boost target from second gear didn't know had the leak and spool time reduced as 60ft, and 330 ft slowest of all day

Did pull a 4th run 10.3 @ 148 mph cal 8 agsin but car had cooled right down by then as was thinking maybe heatsoak and timing being pulled, went round almost no queing and had only just hit 60c trans temp when I did the run so I believe the carbon plenum had cooled right down with less heat, less expansion and less leakage
it was abit better but still way of the pace
And still knew it wasn't right could feel it, that's when I got my tuner on TeamViewer to check datalogs and he saw on the last run only hit 1.7 bar

Shows what power it's got though 3000 rpm launch 0-60 3.5 - 3.9 seconds, a split plenum and still pulling 10s all day 😂🤣😁😁
