  1. You just need the ones angle up, like the last one in the line above
  2. Did you buy the engine, i told you about?
  3. Cause temperature does affect motor performance, the heat at the back of the hover is mainly the heat gained from compressing the air The DC Motor Curve DC motor performance curves can be generated under various conditions. For example, the motor curve illustrated in Figure 1 was created using a rapid test on a motor dynamometer. The test was done by quickly loading the motor from no-load to locked rotor (stall) using a fixed terminal voltage from a power supply with low output impedance. A test like this is done to get a “baseline” measure of motor performance while the motor is at room temperature. Motor shaft speed and current are plotted as a function of motor torque. From this test and a few resistance readings, the torque constant, voltage constant, and terminal resistance values can be determined. This information is very useful to ballpark basic motor performance and can be sufficient for an application that requires intermittent operation with a long rest period between each duty cycle. A typical motor performance curve created using a rapid test on a motor dynamometer. Such tests give a baseline measure of motor performance at room temperature. In applications such as repeated point-to-point moves, applications requiring frequent starting and stopping of a high inertia load, or applications that require the motor to be moving for long periods of time (such as a fan application) the motor data illustrating performance at room temperature is not adequate and can result in misapplication of the motor or exceed the motor’s maximum temperature rating. As the motor temperature increases, the resistance will increase and the torque constant and voltage constant will decrease. This results in an increase in no-load speed and a decrease in locked-rotor torque. Figure 2 illustrates an example of both “cold” and “hot” running conditions of the same DC motor. The “hot” motor curve demonstrates how much the performance can change when operating the motor at an elevated temperature. The graph illustrates changes in motor performance from room temperature to an elevated temperature, showing how much performance can change with an increase in temperature.
  4. http://www.pistonheads.com/gassing/topic.asp?t=748327 Found the above, might be of some use
  5. My money still on starter motor as discussed on monday
  6. quote , it would cost about £40 to send the engine on a pallet, unless you can organise one cheaper. Engine, as described plus starter, alternator and Standard ECU for £150. in essex
  7. ouch, I have a contact for a 2.0 silver top that I am looking to buy, but I am not bothered about collecting it. let me know if you want it. £150 + 40 postage
  8. Yes Marcus, thanks for the info, nice chap. He is coming next weekend
  9. After enquiring about painters at yesterdays meet, I have 3 potential painters coming round to check out the car and provide a quote. Initial budget quotes seems reasonable. This afternoon I decided to make my battery tray and stonechip the engine bay. Folded sheet metal with holes drilled into it. Welded in and primed Engine bay prepared with the help on my swamp rat (aka SWMBO)
  10. Temperature sensor / variable resistor By default the MJLJ is optioned to accept an input from a thermistor type temperature sensor, reflecting the most common usage scenario: correcting ignition advance based on engine temperature during warm-up.

    2.0 Zetec

    Are you selling or telling me to buy the combo from GBS?

    2.0 Zetec

    As above please let me know what you have. Must be running
  13. Not to worry David, I realised that when I say the dates. Enjoy Scotland, wish I was joining you
  14. I am going over to the isle of man for the manx classic between 23-25th of April. I have been trying to change my car season activities. It would be nice if some hoodies like to come along. We are getting an apartment and making the best of the week. Ferry from Liverpool is currently £206 for 2 people and a car. seating and cabin are extra http://www.manxmotorracing.com/events.htm http://www.manxmotorracing.com/downloads/ManxClassic2015_TravelAccomm.pdf
  15. There will be a lot of this on the menu in the nick
  16. Nick, you have a filthy mind.
  17. Catch me if you can, I am related to Usain bolt
  18. Sanding and more progress pictures. Also a picture of me for laughs. Bonnet fitted Meee Not much else to say.
  19. Aaargh, I hate sending cars out for work. As i was not making much progress on the MG last year. I got a classic car company in to replace the last few panels I did not get to. Everything looked alright when i got the shell back. I was sanding around the panel tonight and noticed the surface was springy. Turned out, Mr experienced classic car restorer has filled in holes with PU adhesives. All dug out now and scope of work expanded. I am going to give him a snorty ring tomorrow. Moral of the story is always check work done for you immediately and before you pay. Be patient and do the work yourself if you can
  20. Hi Iain, I am in Manchester most evenings. We can arrange something during the week
