    Just add a bit of info thats not in the video:
    Since filming it, the EML has stayed off, must be down to the HUD I’m suspecting.
    MPG no noticeable difference.
    It actually appears a little bit slower in the side by side, but I think that’s down to me being on a steeper part of the hill tbh. If anything it does seem a little tiny bit faster/more abrupt but it is negligible.
    It doesn’t sound any louder when driving.
    All in all unless you’re gonna do other mods to go with it, it’s a complete waste of time… so I would 10/10 recommend doing it, obviously 🤷‍♀️

    The induction tool - without one - I wonder if you could use an old car battery - using salvaged batt leads - put the positive lead with its batt connection or a socket for size of bolt onto the rusty bolt - then earth the negative lead to chassis could do a similar job🤔 I’ve not had to get involved with rusty nuts yet - was just a thought.
    Might have to connect negative lead close to the rusty bolt then connect to battery when ready

    • @StupidBlokeStupidVideos
      @StupidBlokeStupidVideos  ปีที่แล้ว

      I know what you mean, but no it wouldn’t work unless you put a lot of current through it and it was the high resistance part of the circuit. The induction heaters work but magnetic induction, with some king of current oscillation or some fancy shit.
      You can weld with a battery though 🤷‍♀️

    The bolts holding on the cat to the engine do come out easy even if they look really rusty, did mine as i replaced the cat and thought the same at 1st but in the end they came out ok, also the clutch is a doddle on these, i did mine with only hand tools and now i have arms like an angry gorilla thumping his chest.

    • @StupidBlokeStupidVideos
      @StupidBlokeStupidVideos  2 ปีที่แล้ว +2

      Yea I know what you mean. I think they will probably come out but only had a bit of time at work when was quiet so didn’t wanna end up drilling snapped bolts out. Last time I did the clutch on this shitter was a few years ago and wasn’t bad, probably 3 and a half hours chilled out on the floor but this time will probably take double that if I film it haha

    My cat has had it too. Keep resetting the engine management light but it comes on every 200 miles or so.
    MOT is due end of March. But worried about getting the thing off. It could be a quick half hour job. Or it could turn into a nightmare if one of those bolts snap in the engine block.
    But at least Euro 4 cats are cheap.

    • @StupidBlokeStupidVideos
      @StupidBlokeStupidVideos  2 ปีที่แล้ว +1

      Exactly. That’s why I didn’t take mine off. Tbh it will probably come off with some heat and careful determination, but I didn’t have time to put it right if it did snap. A new aftermarket cat is only about £60 so I’ll just get one of them when if finished pissing shout doing my scientific researching 🤔

    I did this years ago and only found out afterwards that you really shouldn't breath in any of that dust. If anything, the gutted cat affected engine performance negatively.

    • @StupidBlokeStupidVideos
      @StupidBlokeStupidVideos  ปีที่แล้ว

      It’s probably not great to breath in. I regret not doing a before and after comparison tbh but it seemed to increase performance slightly at higher rpm

      I recently swapped my C1 mk 1 for a mk2 and this doesn't have the rev counter which on this model is just a strip of leds. I would like to fit an aftermarket tach and apparently the signal wire connects to a pin on the ignition module. Would be interesting to know if anyone has done something like this. Or even fitted a mk1 "Mickey Mouse ear" rev counter if the wiring is compatible. Only mod I have done to the car so far is putting in a bigger battery, the car had the 012 burglar alarm battery in it.
