  1. My assumption would be the ECU is unlocked, but the mention of the mapping kit only seems to refer to diagnosis rather than changes. I would just be doubly sure that what they send is something you can have someone local to you tune.
  2. I'm trying to remember, but isn't the sender in the submarine for the gauge and a second sender for the ECU? I'm thinking the second sender is down on the left hand side of the block where the plumbing connects. Or maybe I'm just imagining all of this. For those of us with a dry sump, the oil temperature sender is in the bottom of the sump tank. My wiring harness doesn't have what is necessary to connect to it though, presumably because Caterham assumed I'll be pulling wire to connect direct to a gauge.
  3. If you are concerned you can always add your own bump stops.
  4. I have a rough analog that occurred with my build. The transmission kisses a frame member ever so slightly on one side of the tunnel. I tried repositioning using different methods and even pulled the engine and started all over but in the end the transmission is a hair-width from touching at most. I was concerned that movement would cause contact which would cause vibration, but in the end whatever vibration that might be transmitted is minor. Sure seemed like an issue at the time, but in the real world it proved otherwise. Interestingly enough, Bruce at Beachman Racing built a
  5. Love the meatballs! Where did you get them?
  6. Got it. In my mind's eye I was thinking you could shorten the forward arm without lengthening the rear arm and that would shift the axle forward and up.
  7. @KnifeySpoony, just asking because it is something I might have done and we are spitballing, but did you use the upper or lower radius arm mount point on the chassis? If there is an issue here it may not be with the DeDeon being too low but too far back, and I'm not sure if Caterham uses the same radius arm for the S and R. I don't have the Watts. Does it have forward/aft adjustability such that you can move the DeDeon forward to create clearance?

  9. I can do like sf4018 and jack up the rear to see what clearances look like now, but otherwise I'm not going to be much help. I assembled the rear suspension with the DeDeon supported, leaving roughly a one inch gap in the area where I think KnifeySpoony has contact. @KnifeySpoony, suggest adding a photo or two loaded and unloaded so those of us with the same or similar car can compare.
  10. And herein lies why I think spraying methanol/water is a better option. You need only a single tune as the ratio is fixed, and you get all of the cooling benefits, perhaps even more so. BTW, anyone want to buy some bottles of methanol mix?
  11. I had the exact same experience with my 420R. For grins I read the actual temp from the ECU rather than the gauge and found the gauge was reporting back about 5C higher. They still run hot, presumably for emissions, but it wasn't quite as extreme as I thought.
  12. My wife might see thru that ruse if I were to return with a trailer that happened to have a car on it, but as a strategy I think it is brilliant.
  13. Sorry, forgot to mention that the cost for methanol isn't too steep, a few hundred for a kit was my one experience. I think the tune cost more. As for E85, I'm not aware of a cost, but it will require a tune too and coming up with a baseline for pump E85 will be harder than for a consistent mix of methanol and water. And that is the extent of my knowledge, so let the correcting begin!
  14. I'm looking forward to the responses on this one as it sounds interesting! But having said that, my gut feeling is temperatures for the purposes you mention may not be much of an issue. But if I'm wrong, then I might consider spraying methanol instead.
  15. Thanks for documenting this Brightonuk. Last summer I was shopping for a tilt trailer but never pulled the trigger as I wasn't able to confirm what would work (approach angle and weight distribution).
  16. Very nice! Sorry to pepper with questions, but your answer does beg the question as to the compression ratio? Just wondering if a little racier fuel wouldn't bring out a fair bit more power (not that it is needed, of course).
  17. @John B, sorry if you already mentioned, but what fuel was used to get those numbers?
  18. When I'm really bored and feeling flush, I'll replace the key/pushbutton in my Caterham with a FOB/pushbutton solution.
  19. And here is the bottom of the marshmallow getting toasted.

  21. You guys are killing me. My bone stock Seven hasn’t reached its first birthday yet and not seen but a few road miles but now it needs a Cosworth. I need help I think.
  22. It really ejected itself with purpose - straight up.
  23. My Caterham shipped with 13" Avons so presumably I have the 76101 stays. If you want me to measure so you can compare to your original stays just let me know.
  24. I've always been fascinated with the engineering that goes into carburetors. This Constant Depression design looks like it uses an air valve to deal with changing atmospheric pressure. Any problem with that valve would seem more likely to result in a rich condition though, so probably not the culprit. But what about the float level? Is it possible the fuel level is too low in the float chamber?
