    " Racing cars don't have doors. Toilets have doors" : Keke Rosberg

    Comment


      After producing much swarf, I've got a couple of rear uprights, hubs and brakes that I can work with.

      I'll likely replace the cast iron Mazda brake caliper with a lighter Magna rear caliper and I need to finish making the piece between the wheel nut and the wheel. I need to pick up some round alloy stock to make that from.

      Because I was going to have to fit 5 wheel studs where there was nothing I decided I might as well engineer a single wheel nut into the equation, much thought, deliberation and concern went into the design of the piece. It does after all hold the wheel on, but not the disc, in the end I'm very comfotable with the result. I now need to create a very deep socket to fit the CV nut and a deep socket for the wheel nut. I reckon in due course the length of the wheel nut stud will be trimmed after I've finalised what wheels and tyres I decide to go with...

      Very pleased with progress, I need to continue on now with adapting the engine to the transaxle.

          Something had been bugging me for some time, The Hillclimb car has a concerning propensity for stepping out, if you are under power and it gives up traction it always steps sideways. I had long suspected the "LSD" and didn't know enough about it to be able to determine this for sure. This weekend I spent some time researching more about ZF Cam and Pawl differentials, and yes, it is the nature of the beast. They are completely unlocked until under power, then they lock completely. At the moment because the limit of the tyres is so low it means that as the tyres let go it steps sideways with quite some determination. I can only hope that with some tyres with grip we can channel more power into forward motion rather than sideways. The diff will in time wear out and then become a completely open diff.....

            I found that the cam and pawl diffs when they wore out would start knocking edges off and then lock and unlock randomly.
            Great diff when they were new but wear quickly (in circuit anyway)

                  Very Happy with how this all turned out (no pun intended)

                    Faaarking tyres !!!!

                    So there is a tyre war starting up in the UK Hillclimbing scene, Pirelli are entering the fray......there have been some bargain used Avon tyres hitting the market......buying them with South Pacific Pesos inflates the price, but that is just the way of the world.....shipping! fark! such a variance in prices and all of them make shipping 2nd hand tyres across the globe utterly pointless.

                    'Tis a pity, I'd found a perfect pair of front tyres and with the rears on their way I thought things were looking up on the tyre and grip front.

                    Off the back of that setback I thought I'd call Gordon Leven Tyres, last time I spoke to them...last year, their word was mid May, we will call you. Being mid June and having heard nothing ....... "No, no tyres of that size on the shipping list.....Ah! here they are on the order, but they have not shipped." So, I've been waiting for something that will not arrive.... Apparently Avon simply didn't put them in the sea container.

                    A fellow competitor gifted me a pr of Hankook wets, they certainly feel softer and stickier than what we have been running on the front, so I've popped them onto the front wheels, I will now have to reset the front ride height & etc but that will bring the front end closer to the geometry it was designed to have so I'm hoping that will only bring improvement.

                    On the rear I started casting around for something...anything... Hoosier make a dirt speedway tyre in the size required, so I've decided that for $600 I'll try a pair of those on the rear. The bloke that sells them reckons they will grip like nothing I've experienced but isn't sure about how the car will feel on to of them, they have a really loose sidewall. MEH ! what have I got to lose.....

                    One of the other things I notice is that the newly fitted front tyres are almost twice the weight of the ones removed, yuck. And the speedway tyres will be lighter again, I'm not sure how that will change things or if I can tell a difference at all.....

                    I'm quite cheesed off with the cost and hassle of faffing around with tyres. Tyres in so many different diametres and widths and then there are different compounds and construction. Closer to home of course the car has different wheel fitment front and rear and I only have 3 wheel widths all in only 13" diametre......

                    After the construction of the car and achieving a nice power to weight and being able to work my way around most engineering challenges, I'm finding this tyre challenge something I can't get to the bottom of with ingenuity it seems cash is going to be the solution to this dilemma, and I don't like it!

                      One of the guys uses hoosier speedway dirt tyres on his motorkhana special.
                      They are soft as butter and look ok. Id say they will be a big improvement over the tiles you are running now.

                        Yeh, the Hoosier seller was telling me that, same style of tyre I'm getting. I figure if they don't roll of the rim in motorkhana use they will likely be fine for my use.

                          Brrr..'twas a chilly start to the day at Collingrove, frost on the ground everywhere.

                          Fortunately the day, whilst never really warm, was just fine. The car shrugged off the cold by starting on the button, unlike some.

                          We got a full day of 9 runs, I bumbled along mostly in the 36's whilst young David reveled in the new found front end grip and went faster, he recorded a couple of runs in the 34's but must have touched a marker in both runs as they were not counted. Still nice to know that the car has it in it.

                          I had been suggesting to him that he try leaving the line in 2nd gear, he bounced it back to me ( see nobody wanted to stall the car.....) So I tried it, bloody hell! it pops off the line in 2nd as easily as it does in 1st, no gearchanges and a faster first split. So that was a good thing, legend has it that Holinger did this years ago, but he had a 5 litre Repco Brabham....

                          Looks like that is an avenue that we will have to go down, picking just the right ratio to achieve it.

                            Which had us pondering what the car was going to be like with a pair of soft speedway tyres giving us traction.

                            I'm wondering how I'm going to be able to drive the bloody thing, it seems faster than my reflexes already! Maybe, hopefully it will calm the car down and there will be less requirement for reflexes?

                            Either way, very much looking forward to a new traction paradigm.

                              Yeah we often used a single gear at the slower tracks, faster by miles if you can get it off the line.

                                So the tyre saga continues....Hoosier don't have the compound that I would prefer in stock, so I'll be getting the next harder one....next week.

                                Meanwhile there is a thought of building the LS juan into a 2 seat open wheeler...because, short of messing with the car I've already got, to try to fit others in as drivers there is no other way of people experiencing the ride?
