    Uh....racecarsdirect strikes again, I've sent an email inquiring about this collection of transaxle bits in Italy....

    It wouldn't be so interesting, except that the shaft in the picture is identical to the one in my transaxle. Given that in all of my research into these 6 speed "Hewland" transaxles, I've not encountered the same shaft. I can only come to the conclusion that this is a sister shaft to the one I have. This ties in with it's location in Italy.

    It would be interesting to see if other parts shown might even reveal a reverse gear.....there looks to be some spare ratios,maybe..

    Meanwhile, only a short text from Viv to say that he intends getting to my car....

    Top left and top right look like reverse gears (double ramped teeth for engagement), along with small gear in dead centre of shot.

"The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

    It seems there are more bits....including the oil pump, identical to the one I've removed.

    He wants Euro 1600 for the lot, I'd be crazy not to.....

    That looks like a lot of head scratching. Amazing to think how much all that would have cost to build back in the day.

    To assist with the head scratching I've fired off an email to Williams Grand Prix Heritage department to see what light they can shed on how all of this might fit together. They ran a very similar transaxle and are one of the few teams of that era still operating. I just don't get the feeling that Mclaren would help anyone at all....thinking about it they were probably using Weismann in the states by then anyway.

    No answer from Williams, still, it's a busy time of year over there.....

    I spoke to Viv again today, it seems he had got it all together and on the rollers when one of the replacement injectors failed!! He then changed back to the standard Falcon injectors and was going to tune it at that. I decided I didn't want that, I'd rather buy a replacement injector and go for the limit of them and the fuel pump. I mean, there is no sense leaving low hanging fruit, not after coming all this way.

    I've got to say I'm missing having the racecar here, it is taking on mythical beast status in my mind, it seems to have been that long. I've freshened up the truck engine which means the Magna that I bought to tow the racecar is no longer required, it has run out of reg. and I can't be arsed doing anything with it. I've got a couple of cars that need moving around but the car trailer is with the racecar....It's just a bit of a drag at the moment.

    Soon I will have a pile of parts from Italy but not the transaxle they fit in ?

    Electrics! fuck! I'd have electrocuted myself to death by now.

    I'd have to agree that this is my shot at doing something big...

    I must say I am rather keen to read your thoughts on the car after your first full boost drive. I believe it will be a well written piece on how truly insane a monster you have built interwoven with the odd cuss word.
    Mmmmmmmmm beer.

    Hmmm rumble grumble...... A box of parts have arrived from Italy. There are a handfull of parts not in the box. After an hour of sorting through the bits that did arrive, There are a substantial amount of parts which don't suit my transaxle. Whilst I can't complain about that, I can't say I'm not a little disappointed....

    Shouldn't complain, I do now have a spare 1st gear and a whole heap of dog rings and hubs.

    What I would like now is a text from Viv "240 rwkw @ 7800 16 psi come and pick it up" That would just make my year. I live in hope.......

    No such text from Viv, but he did say I could enter a hillclimb on the 22nd of july, I guess he thinks he will be sorted by then...

    Is there a sign on his wall to the effect of "If it were not for the last minute, nothing would get done around here" ?

    Hmmm It's starting to look as if that is the way he rolls...I've entered a hillclimb on the 22nd and he has sent a text saying he is underway.

    I don't think I'd realised what fun I had missed out on by leaving the Echo engine in the back of the little green car standard.....

    On another subject, I just don't understand people who think motorsport should be safe or lets say 'risk free'. I posted a pic of the little green hillclimber (in the 35k road/track car thread)and the first comment was that it was a bit killdeathy. If a racing car is not as light as it can be, and lets be honest here, the little green hillclimber is all mild steel, it could be lighter, then it is not as racecar as it could be. I can't comprehend racing something that weighs 1440 kg like a V8 Supercar. My view is to look at the momentum/energy that one would carry into an accident, the heavier and faster something is travelling the more energy it contains E=MC2 or something like that.... The little green hillclimber weighs 375 kg and is probably only good for 160 kph, means considerably less energy carried to the site of an accident than most cars. I don't disagree that Nascar need massive roll cages, they weigh 1500 kg and travel at 200 mph inside a concrete wall, that is only correct. I just can't bring myself to accept that it is motor racing. So chassis and cage need to reflect weight and speed.

    My experiences with this are having a big crash in a 1500kg commodore, chassis written off everything else OK, left track at about 150 km/h and hit wall 113m later at about 100 through/over a gravel trap. Second incident was a spin in the Radical, braking from 186km/h into turn 6 at QR on what I did not realise was a deflated right rear tyre. Thing spun violently anti-clockwise and went off track to the right and came to rest straddling the inside kerb at turn 6, a distance of 89m from where it spun. Damage was a rim, tyre and starter motor, bike engine you see so it tried to go backwards at 1 million rpm. What I am alluding to here is the lack of mass of the Radical meant that out of control it came to rest from 180 km/h in less than 90m in a cloud of dust, didn't carry through to any barriers etc. where the heavier cars just don't wipe off the energy/momentum like that. Could also be something to do with all that aero stuff producing so much drag when not running in a straight line, video shows I spun about 400 degrees in total. And despite my initial fears, I did not have any issues with an open cockpit after years in sedans. I guess having an FIA approved structure helps too.

    Yes I think momentum is like speed. In that like it takes more than twice the power to double your speed, doubling your weight possibly increases momentum by more than double.

    EDIT: nup, linear relationship, 2x weight = 2X momentum

    careful mixing Terms

    momentum is linear with weight and Speed
    energy is linear with weight, but squared to Speed

    so double the mass for a given Speed = double the momentum, and double the energy

    the 'problem' is energy and Speed. more Speed (for any weight) = waayyyy more energy. that energy Needs to be exchanged through conversion (Brakes/heat) or Transfer (Impact). weight certainly doesnt help, and double is still double, even if it is linear!

    Thanks Ed, I had a sneaky suspicion I wasn't getting the picture quite right. I knew it took more energy (HP) to accelerate a heavy vehicle to the same speed in the same time, but where did it go? Thanks for that.
