    Dropped the car at Prep'd Motorsport this afternoon, waiting to hear if anything is wrong with the geometry.

    Avon guy being very good about it, if it's a bad manufacturing batch, they'll replace all 3 tyres that blistered.

    Part of the issue is that I am pushing the car harder and Indy cars ran a harder tyre in period (I had a set on the Lola). The A11 compound is one off the wet compound, so it's extremely soft.

    Wow! That ain't blistering, those are sink holes! I can't see it being the compound - the rest of the surface looks normal.
    Well done on bringing it home shiny side up!

    It was great to see your times improve over the weekend

    It will be interesting to hear the feedback on whether the cars suspension can be set up differently to achieve further improvements

    about 20 minutes before that photo was taken, I was doing 320kmh on that tyre, doesn't bear thinking about.

    what makes Brett's results more significant is that this is his first experience driving a real ground effects car, with huge venturis. It's the reverse of everything you've learned about driving, e.g. you have to ease brake pressure as the car slows, not increase.

    Then there is the "valley of death" - the gap where you've exceeded mechanical grip but aren't going fast enough for the aero to work. This also catches you out in long corners, as you wash off speed the grip suddenly goes away.

    I could go on, but sufficient to say, Brett is coming to grips with a very difficult car and making it look easy.

    It was great to see the smile on Brett's face and his animated demeanor after he returned to his garage after each session. His support crew were equally excited and pleased about his achievements.

    well I found out why I was having so much trouble getting 5th gear at Phillip Island - the main bracket that supports the linkage had come loose. The 4th to 5th action is a twist and pull, putting maximum strain on the bracket - it was moving about 5mm, which is the same distance as the normal travel of the selector fork!

    It only took a couple of missed shifts to destroy the dog ring :(

    Always satisfying when you find a logical explanation, but I'm kicking myself for not checking the bracket when the problem first appeared.

    I always thought the corner speeds would have been higher.

    Bowe's lines were OK, Guido's were awful.

    onboard cameras make everything look slower than it is.

    Those aren't his normal lines (which are inch perfect) he was trying to block Bowe (the polesitter) who he knew had a corner exit advantage due to a non-turbo engine.

    That March has a Richardson engine, about 550hp (400 is correct for period) and it's 40% lighter than the Ferrari. The event was its last race in Australia, it doesn't qualify for a CoD and isn't correct enough for a FIA HTP (too many F2 bits). HTP's allow replicas, but they have to be 100% correct to period specs.

    Guido spun at MG trying to catch Bowe, which is why you don't see him again in that film.

    btw Darcy Russell DNF'd in his F5000, so both he and Guido should have started the next race from the back, with me in 5th, where I finished the race filmed here. I was not happy to arrive at the dummy grid to find them both in 2nd and 3rd respectively and me in 7th. We run to progressive grid rules and the strategic approach is to avoid breaking your car and make steady progress up the order, so that you're racing for a podium in the final race on Sunday.
