Rolling road result ......

  1. I do no a lot of the basics now as @Joker came over to mine and I did build daisy from nut bolt up !! I help out a few local lads with the basics !!

  2. Thinking of a 1776 but choking it with a center mount carb
    Small valve mexican heads that i will gasflow but not open the inlet ports up much at all
    Maybe a set of ratio rockers on the inlets
    Then the old piper stainless steel exhaust im a fan of

    Its all ideas at the moment but i think it would make a great bus engine
    Especially off road and for going up hill and down dale
    It will be good for pulling a trailer of logs with

    Plus its going to be cost effective to build as it uses a lot of original parts and theres less need to balance everything as your never going to rev the tits of it
     
  3. And so the dub love spreads:thumbsup:

  4. Oooh a square engine, I always wanted one of them when I had my mini.

    What stroke would you need for a square engine and what cc size would it be?
     
  5. I'm Sure I found a thread on the samba where some dude built one with standard 1600 Barrels and pistons and from memory the crank throw was huge 82mm ?
     
  6. Theres not going to be much thickness to the case wall after clearencing for that id imagine
     
  7. Everyone told him it couldn't be done but he built it and by all accounts it was stonking

  8. My whole messing about with cars was because working on aircraft was by the book
    I liked coming up with ideas and solutions to problems and the creativity that was allowed when building cars

    If someone said somthing couldent be done it was like a challenge and i try to find a way to do it

    Im trying to avoid machining the case at all on my build and keeping the engine as simple and as stock as possible whilst improving it to suit my needs better
     
  9. Book values on the 1700 bus engine are:
    63hp@4800
    81 ft-lb@3200

    Zed Gradually getting grumpier

    You can get cases with high roofs that don't need clearancing for 82mm with VW journals or up to 86mm with Chevvy journals.
     
  11. Does the stock tinware still fit?

    Yep.
     

  13. So hes down over a stock engine?

    Am i the only one now wondering what compression ratio that engine has being built with
     
  14. Id rather build with a stock case
    That way if in the future the case is knacked and im short of funds i can build from a stock case
    Cheaper than buying a new specialised crank case id imagine
     
  15. If it keeps running at that and is reliable I'd be happy. Don't forget it's a 'special' which had let go once and has chocolate carbs on (no disrespect) but if it's set up nice and running ok no problem. Wonder what the result would have been with some amber nectar shoved down its carbs though.

    What's the torque result?
    :)

  16. So does this mean it's not far off Paul ?
     
  17. BHP is 6.5%, and Torque 3% down on book values... I'd be happy with that... could even be rolling road calibration error

    Either way, I'd not worry about it :)

  18. I had a guy i built a few ford engines for that wouldent ever have an engine built if it had been oversized
    He said 5-10 bhp loss

    I asked the question about the compression because ive been hearing a lot about low compression cheap engines being built so they get through the warranty period
     
  19. I'm happy with that will do me another 100 miles or so :rolleyes:
