It depends on how Elvington run their event TBH.
At VMax using Bruntingthorpe the cars head off down the taxiway first to build up speed before swinging around onto the runway for a 1 mile acceleration, leaving about 0.8 miles from braking. This allows cars to hit the runway at 40-60mph+ already which "boosts" the final figure vs doing just a straight 1 mile acceleration from standstill.
If I had to guess based ONLY on my own cars performance at both Stage 2 and Stage 3 I'd say this, which might be surprising to some, all based on a 1 mile straight drag from standstill -
Stage 2 - Straight 1 mile drag - 190mph indicated so 185-ish timed (based on the
video of my speedo when I did it and my own
GPS timing gear).
Stage 3 - Straight 1 mile drag - 200mph indicated - only based on a guess of my experience as it's pretty rare to get anywhere to do that speed legally.
The issue is that Stage 2 cars tend to be mapped to 7000rpm, which means that you enter 6th gear at 206mph, but my Stage 3 car is mapped at 6500rpm which means entering 6th gear (which has virtually no acceleration compared to 5th) at around 190mph. So you get to 190mph way faster than a stage 2 car (like 5+ seconds faster), but then have to use 6th gear to go 190-200mph which crawls in comparison. Now I could ask MRC to move the redline for me, but that would ONLY been an extra cost for the incredibly rare times you can hit 200mph (I only did it once in my stage 2 car) so unless I was doing something else with my car, like for example ditching the KWE intercoolers for the new Wagner ones (

) which would need a remap anyway, then there would be little point.
