    Really happy to see more of the little NC. I would love to see the BBR kit on a 2.3 conversion.

      @CIRCUITDRIVERCARS  Год назад +2

      Wouldn’t that be great!! I’ve seen some from BBR on 2.5s that make good numbers and given the cost of good 2.5 engines is certainly an option we’d consider down the line!

      @CIRCUITDRIVERCARS I'm seriously considering an NC now that demand will be starting to drop towards the end of the summer season, with a fettled 2.3 or 2.5 for that extra mid range urgency. I think that would go very well for what it is, especially with a base-spec one like yours at sub-1100kg. I'll be following your development of this car with keen interest.

    Superb video! I bought my NC 2.0 with a view to having a BBR ITB kit one day - I’ve always wanted some for the induction roar! Looking forward to the next vid now.. :-)
    Keep up the great work.

      They really add soul to what is already a special car in the other departments. Feels like a proper, mechanical, old school drivers car, but with relatively modern reliability (hopefully) and usability. 😊

    sul dyno bbr l'auto originale ha fornito 158 hp e 225 hp con il kit montato .La differenza secondo bbr è di ben 67hp . Probabilmente il vostro collettore primario non è molto performante. Realisticamente l' incremento di questo kit è 50 hp .....che non è quanto promesso ma su un motore aspirato è fantastico!! Grazie per il tuo fantastico video !!

    • @CIRCUITDRIVERCARS

      Thanks for the info about the standard car on the BBR dyno, I’m in agreement, not the full 67bhp on the dyno I used, but very impressive nonetheless. Good to manage people’s expectations, whilst appreciating what a huge increase that is on a naturally aspirated engine. 👍

    Watching Clive run it up on the dyno, I found myself thinking it sounded like it wanted to rev higher, it sounded as though it was still pulling strong when it hit the limiter, good to know my specially trained dyno ear is still tuned in. Also glad to see more content coming through and the ending definitely got a chuckle.

      @@CIRCUITDRIVERCARS Once I’ve got the car running right, I’m hoping to. I’ve not done a single day this year and it’s the first time that’s happened since I started in 2008, so I’d like to maintain the ‘streak’. Unfortunately, last time I tried to use it on track, it did 2 laps and went into limp mode, so not ideal…

    Good to see you still have the NC. Very intrigued what your findings are with the ITBs. Really want to go down the 225 route but the it comes with a steep price tag. Have a cheap eBay manifold to go on first and see what I think to that and then go from there I think!

      I’m of the same mind mate so keen to share the experience and an independent viewpoint. For most folk it’s an awful lot of money to spend on a relatively modest car, so really, quite hard to justify.
      With the perspective of spending say £5k on a £5k car, it’s a bit mad, with the perspective of viewing the ‘finished’ article as a £10k car and comparing to other options at the price point, it’s a more interesting conversation.
      I’ll continue to share my experiences and thoughts, hopefully with lots of track fun! 👍

    You’re pushing me to really considering the 225 package for my NC, I’ve just heard a few too many horror stories about poor bbr after care. They will do the work, but god help you if anything goes wrong, they don’t really seem to care. I’ve seen them out really ropey maps onto cars that don’t take into account all the new variables, and end up triggering EML lights. I’m interested in seeing what DanST engineering can offer.

    • @CIRCUITDRIVERCARS
      @CIRCUITDRIVERCARS  Год назад

      Hopefully plenty of use is around the corner and I can share the full ownership experience, any issues and lots of enjoyment of the car! I’ve heard varying reports too, so far so good, they really did pull out the stops on the day I was with them to get the car working, despite a problem with the car I was unaware of. Was very much appreciated!
      They are expensive though! 😅

    • @CIRCUITDRIVERCARS
      @CIRCUITDRIVERCARS  Год назад

      I should add, Will had quite a poor experience with DanST and/or ME ECUs, has a to go t pain for him on his NC. My own take on these is that with the ECUs as they are and DBW throttle, BBR is the standout solution.

    Great analysis. I think focusing on whp is the right thing to do. The way dyno's calculate power at the crank is often questionable and I've seen different results for the same car on the same dyno.
    Would you please publish the dyno graph?
    As well as your dyno graph from the baseline run?
    I'd love to see and compare the torque curves. My worry is that the ITB kit takes away some of the low end torque (sub3500rpm) - your graphs should prove/dismiss my concern :)

      It doesn’t seem to be used very much in the UK unfortunately. At the racetracks here there is generally only ‘super’ unleaded which is 97-99 ron, so we will stick to what’s readily available. 👍

  • @AmaanKhan-te8ll
    @AmaanKhan-te8ll Год назад +1

    The nc love to rev up to 8000 and thats probably where you find your extra 10 hp but being an nc1, I would mostly shift at 7500 just to be safe.

  • @MartinEkh
    @MartinEkh Год назад +1

    i think about 230/240hp with full bbr kit + few extra mods like springs, valve, etc but now it seems not very realistic

    • @CIRCUITDRIVERCARS
      @CIRCUITDRIVERCARS  Год назад +1

      Perhaps possible on a later engine with some spicier cams and more revs… or higher compression.. important to point out that the dyno testing here wasn’t debunking the BBR numbers, just comparing against my own baseline for a ‘how much have we definitely gained’ test. Subjectively I think the BBR dyno is quite generous though.

    I recognise the stroll to Tesco's, but only brought coffee :)
    When I purchased the BBR 200, I was confused by their optional manifold, I didn’t really fully understand the BBR blurb or pricing.
    Anyways, I opted to have the optional manifold fitted.
    However BBR clarified after fitting, it will probably overheat and fail if pushed too hard at a Track day.
    Not sure if would fail a MOT without the manifold, BBR were reluctant to clarify.
    Anybody manged to overheat destroy their BBR manifold?

  • @Boozna
    @Boozna Год назад +1

    On the side of your graph it says 208,4 hp/6887 rpm. Maybe with more revs it will get there. At how many rpm was the 222hp from BBR?
    They say “224 bhp (225 PS) at 7550 rpm, combined with peak torque of 174 lb.ft at 5950 rpm. Over 170 lb.ft is available from between 4000-6000 rpm, with more than 150 lb.ft on tap from just 3000 rpm all the way up to the 7800 rpm rev limiter (MK3 models limited to 7500 rpm)”. So maybe the car will make more hp but I don’t see how it will make 14 more lb.ft. The difference in the exhaust manifold cannot account for that surely.
    This being said your car is very cool and BBR 225 is a really nice package!

    • @CIRCUITDRIVERCARS
      @CIRCUITDRIVERCARS  Год назад

      My take is that the BBR dyno is more optimistic than the Autotronix and I suspect more optimistic than most, which is pretty much where my expectations were beforehand. If I was selling a premium kit for the NC and my own dyno said it made 225, it makes sense to market it that way.
      To manage expectations of others I think it’s a good idea to expect in the region of 205-220 at most independent dynos.
      The most important thing for me is the back to back independent testing vs the baseline we did on the same Autotronix dyno. This power / torque increase, % increase and curve comparison is the more valuable information to me, and tells me that the package is very good indeed.
      I’m old enough and ugly enough to tell it as it is and not proclaim something as good, purely because it’s what I fitted. I genuinely think this kit is THE best way to enhance an NC.
      The one downside for me is the kit is expensive and BBR are expensive. Though this tends to be the case with premium goods and services.
