  1. That’s a shame that lotus encrypt their ECU. I wonder why they go to the trouble of doing this, when some much larger manufacturers don’t. Maxi, it sounds like you have been really unlucky. No amount of ‘use’ should cause an engine failure on the standard tune. These failures do seem to be quite rare though, with a lot of people running at least 460bhp through the stock internals without issue. I’m in agreement that almost all of the KT upgrade packages seem over priced. Having a feel for the modification scene on other platforms (GT86/M4) I can say that bang for buck seems less with the KT lotus packages. I’m sure some of this expense is the large amount of R+D and the quality of the parts/labour, but some of it has to be their monopoly position.
  2. I apologise for getting your hopes up! I’m very surprised that nobody would offer this. If you sourced a smaller pulley yourself and said ‘I want a custom tune aiming for 460bhp’ would they still say no? Potential risk to a lotus tuner = they blow up your engine and they have to replace it. £7-10k?? Potential gain = breaking the Komotec monopoly in lotus performance upgrades by offering a far simpler, more cost effective and more easily reversible solution. Much more to gain than lose IMHO.
  3. Well driven, very impressive. Also, there was a white 350 you were chasing which was rapid. That thing can’t be stock surely?
  4. The solution would be seeking out the most reputable exige V6 custom tuner, then sourcing a smaller pulley, then telling them you are after 460-480bhp depending on what’s safe. We already know the stock exhaust can flow a massive torque increase (see TVS1900) and that’s unchargecooled. Then tell them there is an entire market of people with exige 410s/evora 400s who would be keen for a cost effective power bump into the high 400s without changing out their exhaust/air intake system which is fiddly, costly and harder to reverse. (Carrot) Then tell them you have an internet following and you would be publishing all your results, and the tuner company name online. (Stick)
  5. I agree. But people are talking about the KT460 being more bang for buck partly because it’s more powerful, when a simple drop in pulley size would get you there on any chargecooled lotus.
  6. Could you not quite easily get 460bhp or more out of any exige that is charge cooled from the factory with a smaller supercharger pulley and a tune? The answer IMHO would be yes. The stock engine internals are proven up to ~500bhp, so I don’t know why more 410/430 and evora 400 owners arnt doing this.
  7. Thanks. I try not to take the exige out if the roads are wet, but sometimes one gets ‘caught’. Im leaning towards Cup 2s now, if people with ‘standard’ exige suspension are still saying they are a significant improvement.
  8. Thanks for your response. It sounds like PS4s with a bit of front camber would be the best bet for me. Am I still going to be getting a bit of a performance increase with the PS4s over the stock Corsas in all conditions?
  9. It’s time for some new tyres and I’m keen to get the best on offer. I do mainly road use with occasional track. However, everyone always says that the V6s suspension isn’t ‘optimised’ for track and we should be upgrading to Nitrons or Ohlins etc. I have no plans to upgrade suspension. Does this mean that very high grip of the Cup 2s or Trofeo Rs (in the warm) is not suited to the V6s suspension and could overwhelm it in the corners? I’m also interested in how much worse the Cup 2s or Trofeos would be Vs PS4s in standard road driving wet conditions. Thanks
  10. The arguments for modding would be if you want to teach yourself how to do car stuff, or if you want to creat something truly personal. If you don’t fall into either of those categories, then don’t do it. I would get a V6s, and add some gearbox shift cables for the summer, then enjoy it, and spend 8k on something else. If that’s not enough then buy a V6 cup.
  11. I would like to try and offer an explanation in 2 parts: 1) the forced induction system in a golf R will likely deliver >20psi at 2000rpm, whereas yours is probably giving about 4 psi. This is a big difference. This is partly why his car is feels rubbish to drive and I would never buy one. Turbos get to peak boost quickly, then offer very little reward for continuing to rev. Superchargers are more progressive and controllable. 2) I wouldn’t compare performance in uncontrolled road races because you don’t know whether his car is stock, when he pressed the accelerator, or what gear he was in. As an aside, I’m yet to drive any turbo car (including a mclaren) which has a good throttle response or a progressive feel to it. If anybody has driven one, please advise. (Maybe the newer turbo Ferrari’s or a 911 Porsche...?) Ironically, if it’s just torque you want, the TVS1900 upgrade for non-chargecooled cars delivers KT460 levels of torque (I.e. a lot) up to about 5000rpm.
  12. You don’t need to run it as rich when you have a much larger charger blowing cooler (still un-chargecooled) air in. The SSC map has presumably been designed with the intention of avoiding detonation.
  13. Hi Dave, does it do anything regarding the vulnerability of the shift cables to heat, and therefore for the problem of increased propensity for miss shifts while on track? Thanks
  14. What are main benefits of this 350 gear shift mechanism? Does it help with the overheating cables issue the V6s has?
