  • Went on a trip to the Old Timer GP at the Nurburgring two weeks ago. For anyone that likes watching historic racing right up to 90's touring cars, I'd recommend a visit. Even car spotting on an evening outside of eateries in Adenau, where we stayed, was an event.

  • Anyone fancy Russias answer to the Tesla?

    The Kalashnikov cv-1.

    I'm going to admit I love the retro styling which was apparently deliberate but no way would I trust it to not break down at every opportunity

  • skoda 110 / 120 / 130 rs above ?
    love those cars
    took a donor engine out of one to put in my skoda 105s when a teenager

    saw a nice one with a rover v8 in doing the prescott hill climb back in the 1980's

  • No way. Redline well beyond 6750.

    Interesting, I think j I've been a bit nervous to rev too high after my unfortunate incident with the engine and the big hole.

    I'll go back and look at the dyno graphs.

  • Thing is, the graph doesn't have a revs axis. How best should I interpret this?

  • and there's no point in more RPM if they don't deliver

    Seems fair

  • i checked my bill, no brand names on it, just "fix and replace rear calliper" - sorry!

  • Interesting... This is my current Thunderbird 4 inspired solution.

  • the way i read it is 71kw (c96bhp) at the wheels which he has calculated back to 112BHP at the flywheel.

    (just tell everyone 112BHP)

    i was a bit annoyed that i couldn't get a tonne at the wheels

  • Yeah, but no idea at what revs the power comes.

  • you can work it out.

    1:1 in top
    3.909 rear axle ratio
    185/70/r14 wheels

    speed on the bottom of the graph

  • Anyone fancy Russias answer to the Tesla?

    Yes I do

  • @mashton

    a smidge under 5100rpm, by my calcs

  • Ah didn't go for the old trick of thinner oil in the drive train ;) reduce the actual transmission loss than on the calculated one. Some people use different heat range of plug too

    On anything I have had on rolling roads, I've never cared for the BHP reading. It is a bit variable from day to day on the same machine and some machines being optimistic and other pessimistic. Just want to know that the fuelling and ignition is right.

  • KGB infiltrator?

  • KGB infiltrator?

    I hope that is the UK name for the car.

  • @lynx

    the dude at sanspeed did mention hotter plugs for track days, just as a safety thing. it was there for the tune, rather than a reading, but it was nice to see what i got building an engine on my own.

    it is not bad for a 50s engine - i am after 150 for the racer. the guys at the front must be pushing 180bhp or so, but they all cheat.

  • Rather than me choosing a stroke I've set some goals and asked Mike to pick whatever combination of stroke/cam/valve/etc would get us closest to them. They are, in no particular order:

    8,200 rev limit
    Peak power delivered ~7,800 rpm
    Enough torque for a road engine in a (fairly) lightweight sports car
    400 bhp

    This seems like the most sensible way, you say what you want from the car, the engine builder builds a suitable engine.

    Flippant remark: can't he build the equivalent of a 4.0 mezger but not using a mezger? That engine has everything you want, no?

  • I came here to see if this was being discussed.

    I love it. I think the styling is excellent and I would buy one 100%.

  • Flippant remark: can't he build the equivalent of a 4.0 mezger but not using a mezger? That engine has everything you want, no?

    He routinely builds 4.0 litre Mezgers, they have a wider bore spacing, not having been based on the 2.5 litre Boxster engine, so they run 102 x 80.4 rather than the 100 x 85 that we'd have to run. That's a lot shorter stroke, which makes higher revs more straightforward.

    The Mezger head carries a 41mm valve whereas the largest we could fit would be 38 (stock is 37).

    However, if we get it right we'll have an engine specification that can be built out of almost any 3k scrap M96 engine - and it'll be powerful and reliable at maybe a quarter of the cost of a Mezger.

  • Now spark plugs are something I know a very small bit about. But no longer sure of the relevance with modern fuels. Also different people have different opinions.

    From what I remember, it could make a different. Some cars were set up for round town while longer runs and motorways meant using different grade of plug...your car is from that era ;)

    Still laugh at some of the spitfire plug adverts, never let the rules of physics ruin a good advert.

    It's not cheating it is...have fuck loads more money to throw. If you are really bored look in to how tech has helped e-types become as quick as the ferrari and how the pre cross flow ford engine can make similar bhp as a lotus twin cam.

  • why not just get a rebuild kit from big Red, I imagine it will be around the £20 to £30 mark

  • the big red dudes are good to deal with - the briochely express has rebuilt calipers from them

  • ah ok, should have guessed there were some big differences.
