Gate 6 is the high G turn after the big oak tree that makes this course unique
It's a tough one for the pilots, who have to really set up perfectly to approach gate 7 without correcting
Goulian flies next after progressing through by virtue of the DQ for McLeod – it was a lucky break and he'll take home points that would have eluded him otherwise
The American is flying precisely and it's a strong run – that's excellent from Goulian – his fastest time all week when it matters most
And Muroya to fly next with only one thing in mind – to smash Goulian's time!
Muroya is worthy of a place on the podium here and although he's in the red after the first split, he's regained that time for the second split
- Pylon Hit!
It's our first pylon hit for today! That could give Goulian a place in the final...
It's all over for Muroya with those extra 3s... he walks away with 01:06.874
HALL // GOULIAN are through
Matt Hall: "We found a few things after yesterday and fixed them."
Arch vs Lamb next – lucky break also for Arch, who makes it through as the fastest loser... after the DQ for Kopfstein
He's into the track and his Ascot curse could get the better of him...
We saw a revised line there, to avoid the earlier wing stall
low in the chicane and he's now into the back leg
it's a great time for Arch – clean and a personal best!
Lamb is up next after blazing a trail in the Round of 14... and with the added pressure of this being his last race for the home fans
He's the 2014 World Champion and needs to show the fans he's still got what it takes!
He's in the green at the start, but let's see if he uses the MXS-R to really capitalise on the turns - yes, it's green!
And that is the end of his Ascot race...
It's red at the final moment and he stops the clock in 1:05.030
That was the closest of margins, just +0.212 behind Arch
Last heat of the Round of 8
And for sure, the most exciting!
Sonka has been on top form and a worthy rival to championship leader Dolderer
This one could go either way
And if Dolderer progresses, that gives him the chance to really break away from the pack
