Straight to the point, nice! :yes

I was up at santa pod at the PTM show today to test out some new techniques. It was pretty hot so I don\'t think my intake temps were ideal. my best run came after leaving the bonnet open for half an hour! Also I had about 50 litres of fuel in the tank!

I found that a burn-out made no difference to my launch and actually my best 60\' was with none at all.

here are all of my times:

13.56 @ 103.92, 60\' 2.10
13.88 @ 103.56, 60\' 2.34
14.03 @ 103.91, 60\' 2.49
14.03 @ 104.30, 60\' 2.36
14.21 @ 106.23, 60\' 2.49 - best ever terminal speed - banging the limiter in 3rd!!
14.21 @ 99.57, 60\' 2.47
14.40 @ 102.90, 60\' 2.49
15.54 @ 100.38, 60\' 3.77 - I started in reverse on this one!

I am absolutely over the moon about my best run - getting a 13.5 was what I felt the car could do and I got my best ever 60\' with that 2.10 - I think I surprised the two 380bhp evos I was racing! I found that changing up around 7.5krpm worked for me and I was launching at 4.5krpm.
