michaeljf Posted January 15, 2021 Author Share Posted January 15, 2021 Hello Nick, The original wheels will actually be an inch wider when I am finished with them, the white basket things (Compomotive) are off a rally car ( sons Very radical Datsun "1600"(2000 T/C 2x50mm twin throat carby's) dog box,R200 diff, ohlins coil over all round, full FIA cage, etc. "classic class", they are the heaviest and maybe the strongest and he has 10 of them. The BBS are the lightest by far AND the widest (6.5x15). The white baskets would be only very temporary use IF I don't get the steels finished in time. Regards, Michael.

Hamish Posted January 24, 2021 Share Posted January 24, 2021 I admit I went with the cheaper option of the minilite copies for my 3a my road tyres (very wet track days) are silver vredestiens sprint classic 185/70x15 my race (sprint and hillclimb road legal) tyres 185/55x15 are black with cut silver rim i have just bought another set that have just been painted black for a used set of Avon cr6zz 185/89x15 tyres road legal but intended for higher speed tracks like aintree. I changed to 4.1 diff so with 55 profile tyres a loose a lot of top speed which isn’t a problem as most sprints and hill climbs. the 70 profile help the speed a bit but loose some stability on the corners.

Very pleased with them. Curborough fig 8 sprint is about 79 s on road tyres to 73s with maxsport 6 seconds in just over minute run is a big chunk of time. the soft wouldn’t last on a circuit of a few laps.

michaeljf Posted February 24, 2021 Author Share Posted February 24, 2021 Hello, Spoke to the man making the pushrods (in Melbourne) today and he says they will be made by the end of the week. How do you like the bracket for the alternator? The other picture is the original head. Regards, Michael. Link to comment Share on other sites More sharing options...
Nick Jones Posted February 24, 2021 Share Posted February 24, 2021 Alternator bracket seems to have been on a serious diet...... Looks like a proper MikeThePipe 6-3-1 manifold in the second pic Link to comment Share on other sites More sharing options...
michaeljf Posted February 24, 2021 Author Share Posted February 24, 2021 Hello Nick, Yes, serious enough to turn it into an anemic colour. Pipes were given to me by a SERIOUS racer but need some serious work! Regards, Michael. Link to comment Share on other sites More sharing options...
Chris W Posted February 25, 2021 Share Posted February 25, 2021 Hi Michael, Great thread you have going here. Could I ask what you have done to delete the fan extension? I've seen kits available from the States but nothing in the UK. I appreciate you are in OZ so did you machine something yourself? Cheers Chris Link to comment Share on other sites More sharing options...
