Went to Phillip Island trackday yesterday

Wow that is really cool Pete, how do you get the whole lap time/speed map thing on there, what do you use?
It gives me a idea of the track and how fast you are taking the corners, really good to study, would be nice to compare it to something else

The video is made up in two parts.

Part 1 is the race footage itself which was shot with a GoPro Hero HD camera mounted on the dashboard.

Part 2 is the data animation overlay.

• GPS data is captured by an Android Phone running TrackMaster software. (US$9.99)
• The raw GPS Data is animated as a video using racechrono2avi software (free)

The race data video is overlayed on the race footage using Pinnacle Studio12 video editing software.

Were the conditions slow (wet patches etc)? I would expect much better times than that.
Were the superkarts 125cc 2-stroke ones? 250 twin 2 strokes should be down in the 1:30's somewhere.

Out right car lap record is 1:24 in a Formula Holden om slicks. I know super carts are quick but dang bro any thing undr 1:50 at PI is on the magic cloud...

I'm surprised that the 125s gearbox karts (I only associate the term superkart with gearbox/shifter karts) aren't lapping around the 1:40 mark given the aerodynamics, center of gravity, power/weight and tyres. The International 250 gearbox record that was posted (in the 1:32s) is where I expected them be but I would have thought that the 125s should be a lot closer than 10 seconds adrift.

Cool stuff! Interesting to see Sean Whitfield has the LR for Rotax Junior.. I remember he was a Rookie back when I was racing.. The old man had bags of money (bags!!) but they were nice people...

The straights are too long for that, dude..

The interesting thing I've found out is, that 125cc Gearbox Lap Record was a touch controversial when set…

The guy was apparently running 1:44-45's, which is supposedly the best you really can go with that type of kart, and very quick for what they are.

Then it managed to clock a 1:42.7 - apparently he drafted a 250cc to achieve it, so odds on it being beaten are small.

PI is one of those tracks where the 250cc can use there extra power a lot more, compared to say Winton where the difference can be very little.


It terms of track day costs for your car, it was $165-175 depending on the Sat or Sun. Which is great value I think for the amount of a sessions you get, without an excessive amount of cars on the track. If you're thinking about it, there are always plenty of experienced people there to assist and take you out showing you the track, even driving your car first up to advise lines, braking tips etc

The straights are too long for that, dude..

Why is that? Can't they fit a small enough rear sprocket???
Peter Galvin has the National 125GP bike record down to the 1:41:632 and the International 125GP bike record is 1:36:927 (Alvaro Bautista).

Im pretty sure Super-karts are not allowed to draft aswell.

[kaanage]

Times won't count if you draft a kart in another category but you can draft your competitors. And any powered non-drag racing (as opposed to time trialling) without drafting is basically impossible.
