  1. it's 15, and Google agrees with me. It would have to be (5+5+5-5+5+5-5+5) x 0 to produce zero. It's nothing to do with computers. When I was taught that brackets and multiplication and division took precedence over addition and subtraction the Lyons Leo III was cutting edge technology. (EDIT: Anyway, even if we were talking about computers, the code to parse a maths expression would ignore the spaces.)
  2. The engine looks like a Harley Evo. http://www.harley-davidson.com/media/images/productphotos/PNA/16161_99_M_16ab0.jpg Forks could be newish as well, Harley sold springer models until this year, and there are aftermarket versions. The design goes back to the 1920s (George Brough nicked it for the "Castle" forks fitted to Brough Superiors).
  3. Once upon a time you couldn't buy replacement bushes for the Soarer, then an Aussie called Andrew Vlamos (VFT Bushes) had them manufactured (plenty of stuff on Planet Soarer about these). I don't know if VFT are still trading. Some time later, "official" Toyota bushes became available... allegedly supplied by VFT. Later still, Branz bushes arrived - http://soarerparts.com/products.asp?cat=7 (ignore anything marked "UZZ32", that's the V8 with active suspension)..
  4. There was a question earlier in the thread about "PS" vs "BHP". PS (Pferdestärke) is the DIN calculation, as opposed to the SAE calculation, and 1 PS = 0.98632 BHP http://www.emeraldm3d.com/rolling-road Written by Dave Walker. He has slightly different views about calculated flywheel figures, in that they have proved accurate when he's been able to compare them with engine dyno numbers (although he's talking about a Sun rolling road dyno that "measures a maximum of 330bhp at the wheels up to a speed of 160mph"). What he has to say about single vs twin roller is interesting, though. More modern rolling roads tend to have one very big single roller and you park the car on top of that roller. The main reason for this system is so that you get less tyre distortion with a single large diameter roller. With an older system using twin rollers, you get more rolling losses because you have two contact points, not one. Car manufacturers like Mercedes who make powerful engines and very heavy cars will only allow their dealers to have single roller dynos to limit the tyre loading – it’s a safety issue. Several factors prevent you from getting exactly the same result in every gear. First off a lower gear means more torque at the wheels and hence a little more tyre slippage than when you run in a higher gear. The run also takes less time, so the engine accelerates faster and gives you more of a "flash" reading. Our Sun Ram 12 rolling road allows us to alter the acceleration rate so that we can adjust it for different power outputs. The software in our system uses the road speed, measured by the rear roller, to obtain engine rpm in order to scale the power curve. We take an rpm reading at 60mph and the software works out the revs at any given road speed from there. What this doesn’t take into account is tyre growth. As the revs increase the centrifugal force makes the tyre grow – which alters the gearing slightly, putting the rpm out by a tiny amount. When you take all these "fudge factors" into account, it’s a wonder the rolling road is as accurate as it is, but it can be accurate, and more importantly, repeatable. With careful setting up of the acceleration rate to match the engine power, and accurate setting of the engine rpm, (dashboard tachometers are often out), you can get a meaningful number from a rolling road. I know that when trying to improve the engine in the 'Red Shed' our rolling road is depressingly accurate enough to give the same power curve time after time – despite my best efforts to increase the power output! I always call our final figures "simulated" flywheel figures but they are close enough to engine dynamometers judging by the comparisons we have available. Ken Snailham at Q.E.D recorded 218bhp on his dyno and the same engine showed 220bhp on our rollers. We've had similarly close results to the Lotus Service Centre dyno and J.E. Engineering’s dyno. We also see close to factory-quoted power outputs on most standard cars that we have run in the past. Hub Dynos A big problem with rolling roads is tyre grip. As power outputs reach the levels where you question the sanity of the engine builder it gets harder and harder to put the power down. On a rolling road you usually have more grip than you do on the road or track but I leave problems like that up to the driver – the throttle tends to work both ways after all. The answer would appear to be to eliminate the tyre from the picture. A hub dyno bolts directly to the drive shafts so there is no slip at all. This, on the face of it, would appear to be the answer to all our problems, but you still come back to the question of what you are measuring. By removing the tyres from the picture you get much lower rolling losses but not enough inertia in the system to measure any sort of run down. For setting up it’s probably the perfect answer but not much use for comparing one engine to another as you can’t get back to what the engine is making at the flywheel.
  5. There are some "campaigners" at a loose end now that the Dale Farm issue has been resolved. Perhaps they'd like to move from defending the Irish Travellers' rights to defending the rights of 4-year old Romanian Romanies (at least the Roma are real "gypsies" ).
  6. Yes, don't expect an A-Series Mini to be quick by modern standards. (or... fit a BMW K100 head and EFI) More seriously, I wouldn't have thought that a different carburettor would make much difference to the performance on its own, you might as well stick with the SU if there are no other mods.
  7. Excellent. Just let me know how much.
  8. We hear "indefinitely" and think "for ever". The medical and legal professions hear "indefinitely" and think "could be a week, could be 30 years".
  9. There's load of stiff about this all over the web (plenty on Youtube and Pistonheads). I think it may be true that you can be prevented from taking photographs on private property, but the police were talking rubbish when they mentioned the anti-terrorism act. http://www.independent.co.uk/news/uk/home-news/photographers-criminalised-as-police-abuse-antiterror-laws-1228149.html ...according to the Association of Chief Police Officers, the law is straightforward. "Police officers may not prevent someone from taking a photograph in public unless they suspect criminal or terrorist intent. Their powers are strictly regulated by law and once an image has been recorded, the police have no power to delete or confiscate it without a court order. This applies equally to members of the media seeking to record images, who do not need a permit to photograph or film in public places.". I suppose we should be grateful that we didn't just copy the US Patriot Act. He could have found himself wearing an orange jumpsuit and locked in a cage on the Isle of Wight.
  10. Leaving aside the usual question of why stealing £50,000 from a bank would result in a rigorous police investigation while stealing a £50,000 car probably wouldn't... One of the illustrations for the Daily Mail article on car theft is a forged South African log book for a Supra.
  11. , but you have to mate it to the Supra harness Depends where the W58 originated. The easiest option is to start with a complete manual N/A Mk4 Supra, then you have the correct flywheel, clutch, bellhousing, gearlever, and propshaft. You can use the auto Soarer ECU with a wiring mod, but you have to mate it to the Supra harness.
  12. W58 conversions on TT Soarers seem to work for the Aussies. Forums: http://soarercentral.com http://alscforum.com
  13. You would have to remove the hubs to do the rears, but the fronts are easy http://planetsoarer.com/suprabrakesII/SupraBrakeUpgrade.htm Cut a section out to remove and replace them (as in jonc's post in this thread):
  14. Toyota's requirement is T-IV. All those listed claim to meet Toyota T-IV specs. http://www.amsoil.com/storefront/atf.aspx http://www.motul-oil.co.uk/pdfs/gear-oil/Multi_ATF_TDS_(GB).pdf http://www.fuchs-europe.de/fileadmin/fuchs_upload/downloads/pr-texte/TITAN_ATF_4400.pdf http://millersoils-online.co.uk/millers_oils_which_engine_oil.cgi?_name=MILLERMATIC_ATF_SP_III&product_id=214&exact_match=on Other than that, I can't say. I've always used Toyota T-IV.
  15. Any help? http://www.guardian.co.uk/money/2008/jul/30/banks.savings

    IIRC, you now have to either use permeable materials or drain rainwater into the garden or obtain planning permission, even for a replacement driveway. Check the Government Planning Portal.
  17. Well.... ferrets are domesticated polecats and are white, sandy, or polecat coloured (although I think pet ferrets have been bred in some new colours). Joey and Tim definitely weren't polecats, in the same way that a German Shepherd isn't a wolf.

  21. You think so? http://www.visordown.com/motorcycle-news--general-news/bike-ban-in-french-cities/17766.html France's Ecology Minister Nathalie Kosciusko-Morizet has proposed a ban on older bikes and cars in eight French cities from 2012 onwards according to French newspaper le Parisien. When we say “older” we're not talking about smoky old strokers but any bike made before 1 July 2004, which would actually account for a large proportion of the entire motorcycle population. Cars get off a bit lighter, with anything made since 1997 still given the OK. France > EU > UK
