    Kelford also do a split duration camshaft which although not a traditional PolyQuad (yes this is one of Vizard's projects) it does provide a similar effect, I'm running them in mine with reasonable success. I was supposed to be on the dyno today but with Stage 4 lock down in Melbourne I can only sit in the car in my garage and make wooshing noises.

    Tried to PM you, but you can't receive messages.

    Anything in particular? Mine's built to specific regulations that probably don't cross over much with drifting, but I'm happy to send you some engine bay pics if you like? It's all pretty standard stuff really, the only thing that's a bit different to the usual is the cooling system which uses a custom made cross flow twin pass radiator and swirl pot.

    The car has run with the standard manifold but return flow intercoolers are average at best and aesthetically I cannot cope with the tortuous path that intercooler pipes must follow to use the standard manifold. This Plazmaman unit makes use of the standard lower runners so does not reduce the overall intake length too dramatically and allows me to use a Plazmaman GTR intercooler and neat pipe work. The engine is built to produce maximum torque at low rpm (from an RB20 LOL) so has high static compression and custom made split duration Kelford cams to promote better swirl in the chamber before it reaches positive manifold pressure. Hypergear made me a very custom turbo so that I still comply with my class rules but it should make 300rwkw without too much problem, back on the dyno in August after a few more changes. Previous best with this engine combo (but 21U highflow) was 265kw but boost control was non existent because the internal gate was too small so we didn't run it past 5500rpm.

    It's got a fully optioned M600 at the moment but I've just ordered an M150 and dev license for it. One of the reasons for going to M150 is more inputs, I'm out of space and that's with the dash upgraded for extra I/O. I could probably drop a few of the less critical inputs off and only connect them for testing but the added flexibility of the development license for M150 is certainly worth a few extra dollars. My I/O list is similar to yours but I don't run N02, it's a rally car.

    Yes, it's got most of the Motec catalogue in it so runs just about everything you can think of. Just missing tyre temp sensors and suspension position sensors I think. At the moment it runs 'traditional' Motec traction control strategy but I was considering a DBW TB in the intake pipe after the IC to bleed off boost as a form of TC which was very effective because it doesn't impact engine speed an efficiency as much as other strategies. A mate ran his IPRA car like this with excellent results.
  7. Komdotkom
    It's a race car and has Motec everything so DBW is used for idle control and I'm a big believer 'in if it's worth doing, it's worth over doing' I wanted a forward facing TB and would have had to purchase a larger unit anyway so there was essentially no significant cost difference between DBW and a cable throttle.
  8. Komdotkom
    Mines just a single TB on a Plazmaman intake, not the ITB setup so it's nothing fancy. This is from last year.

    I must win the over capitalisation contest then, my RB20 is DBW!
  10. Komdotkom
    Sounds like you are challenging me for the most overcapitalised RB20 in history.
  11. Komdotkom
    Yeah, that Spry bloke hasn't got a clue.

    As others have said it's not that simple. I didn't bother trying a timer (for pump start up) then SSD voltage control vs wheel speed because that car didn't have an ECU that could easily be made to do that (Autronic SM4). I would still use a powered column if I was to do it again since they are simpler to configure the amount of assistance provided.
  14. Komdotkom
    Hmm, not on the GCG website and Ebay is showing they are out of stock. I wonder when they'll actually be available. Price seems to be about the same as an 8374
  15. Komdotkom
    Not that simple with the Astra stuff unless you know the CAN protocol. If I was to do it again I'd do a powered column instead of an electric pump.
  16. Komdotkom
    Following with interest, while I agree it's a pretty expensive bit of kit for what they provide but when you consider that you could ruin a race weekend with a damaged belt or bin the car due to power steering failure it doesn't seem so bad. FWIW I have put Astra electric power steer on a car and would never do it again without being able to adjust line pressure vs wheel speed, it was like driving a 70's Valiant with power steering with zero feel/feedback.

    My tarmac rally car had one of these in it! I couldn't find anyone with a computer that ran on steam to tune it, so the logical solution was to spend $15k on Motec shit. I'm pretty sure it's still in the shed if I can find it you are welcome to it, has a tune for RB20 with highflow and made about 7kw at the wheels, good for 1:45 at Sandown.
  18. Komdotkom
    That must be a handful, 200kw to 400kw in 500rpm. Thanks for taking the time to post something interesting and some real world results.

    I need a core to send in for highflowing, anyone have a dead OP6? Or even just the front cover?
  20. Komdotkom
    What has changed between the older version of the 21U highflow and this one?

    I've got a mate with a JRZ package on his IPRA car, and another mate has them in his 996 Turbo, they don't and shouldn't make this noise. I would 100% be making a warranty claim on these because that's not a 'normal' noise for a set of $1000 BC's let alone a high end manufacturer like JRZ. To me it doesn't sound like an internal damper noise, I'd be looking at all of the mounting points and investigating areas for free play and movement to occur. Another good street/track option that's got decent support in Japan is the lower spec Ohlins Road&Track. https://www.ohlins.eu/en/products/automotive/nissan-skyline-gt-r-1993--29/ Or just get a set of MCA's, I've got the gold series on my car (3 way) and they fantastic. There's no local support for them but you can just ship them back to Murray in Australia and he'll do whatever you want and then ship them back to you.
  22. Komdotkom
    Good luck mate, I searched for ages before I found one.
  23. Komdotkom
    At the risk of sounding like a smart ass, there's a lot more to it than 'mono tube are better' For example, arguably the best dampers in the world the Ohlins TTX 40 are twin tube (that's what the TT stands for) https://www.ohlins.com/product/ttx40-mk-ii/ Having said that, they are a well researched and engineered solution from a company that expends a huge amount of time resources on a product that works. I think generally speaking for less well resourced/mass market companies a montube is simpler to execute to a higher standard and provides increased flexibility when pushing out designs across a number of platforms.

    I've just started using RevZone and have been pretty happy with the work. I like to understand exactly what happened on the dyno and review the logs, issues and solutions with the tuner which Justin and his team are happy to do. My car has a fair bit of Motec gear in it and a pretty custom setup, so it took some mucking around to get it right. When I got the car back, the cold start wasn't awesome (not terrible either, just some hunting around 20c) so I sent Justin a quick email to see if they could give me some pointers as to the cause because there's a few comp tables running concurrently at that time in my setup. Rather than just give me the answer or tell me to bring it back, he offered to send his tuner to my house to fix the problem free of charge. Pretty good service I reckon. I've had cars tuned at many other shops in the past and have been less than impressed. Good power tunes but shit attention to detail and poor drive-ability.

    This is surely a troll of epic proportions. Is it school holidays again?
