  1. I sent them a few emails ( to a few of their different mail adress ) in the last weeks to get some info about the supercharger belt braking on their watercooled kit and at the moment I also did not receive any reply.
  2. Thanks The exhaust manifolds and sports cat are from Komotec and the rear muffler is the standard one
  3. Sent them an email thanks So you are using the watercooled SSC kit but the work to fit it was done by Komotec? Or did they just fix that problem later?
  4. Following my other topic about a snapped belt on the TVS1900 supercharger I would like to know how the belt tension is adjusted on the 2GRFE and how can I check if the alignment is correct? Thanks
  5. Hello Dave Thanks a lot to take the time to reply My car is fitted with the Komotec carbon airbox and there is also a Mocal oil catch tank with breathing cap fitted in the same way as on the cup R After the trackday I cleaned the MAF sensor with some brake cleaner but the air intake was not particularly dirt on the inside. I checked for codes with a generic OBD2 reader ony when the car was back in the garage and not immediately on track, and I did not check for ABS codes ( don't know if the obd2 reader would read those? ) I have to say that before the 460 kit the car was fitted with the 430 kit without watercooling and on the same track it was feeling more reactive and performant with the 430 map as if the timing was more aggressive. To know if an o2 sensor is faulty the dealer software is required? In this video it was using the 430 kit where I found it was working really well
  6. Thats interesting Do you know where I can look at the alignment procedure and if it requires special tools?
  7. On my exige 380 cup I use REDLINE MT90 for the gearbox ( depending on the use you might want the MT85 ) and castrol supercar rs 10w60 for the engine
  8. Hello My Exige cup 380 is fitted with a komotec 460 kit On a warm trackday after just a few easy laps when back on throttle it went into protection mode with the 3 shifting red led blinking and cutting power at 5000 rpm ( No CEL and No obd2 errors stored ) After restarting the car and going back on track it was working well again, but it felt slightly underpowered as when a non watercooled Lotus reduce timing because of heat When at komotec they replaced one of the exhaust O2 sensors as it was not working well and then at another Lotus dealer they had to replace one again so I was wondering if anyone have particular problems with O2 sensors failures or MAF getting dirty and need cleaning or some other suggestions Thanks
  9. The work was done by a Lotus specialist in Italy they build racing and time attack cars and they know that the belt can be a problem on some applications. They also offer a specific modification to solve the problem but I tought I would ask on the forums to know if anyone had problems with the belt and if there are other options to look for as special belts etc... When it was fitted with the aircooled tvs1900 the belt never broke. I would say it doesnt look out of alignment but if anyone have pictures or instructions to check alignment and adjust belt tension let me know. Anyone know the specific belt reference used on the SSC watercooled tvs 1900 kit? Thanks
  10. Hello I recently made some upgrades on my Exige V6 cup R ( you know that old track car that Lotus used to made before the EMIRA ) The car was already fitted with an air cooled tvs 1900 and mapped at around 430 bhp, and was working very well Then it was upgraded with the SSC TVS 1900 watercooled kit, forged internals, 430 cup throttle body, custom exhaust and custom mapped on the dyno to around 490 bhp The problem is that after just one session the supercharger belt snapped and I m told that on high power cars used aggressively on track the standard belt can brake even if everything is correctly aligned etc... Maybe with the xtrac gearbox it s even worst? BTW doeas anyone have any suggestions or know if there are some reinforced belts available? Thanks
  11. It s a cup R so the original ECU is a Lotus Motorsport ECU ( based on the standard one ) that is already specifically mapped for the use of the Xtrac sequential gearbox and I think without any torque limiter and then It was remapped for the TVS1900 Pistons were fitted last year and are from wiseco ( not their latest spec as lately wiseco made a slight design change ) and I think the rods are Carillo The valvetrain and head are standard except the valve springs just for reliability and the head gasket
  12. I recently got my Exige cup R back with the SSC charge cooled TVS1900 kit fitted as well as some other little tweaks as shiftec steering wheel carbon paddles ( as on the eleven race car ) , 430 cup bigger throttle body and a custom exhaust with bigger tubing size as per the 430 cup versions. My Exige was already fitted when I bought it with the air cooled tvs 1900 custom manifolds and custom mapping and it was making 430 bhp on the dyno. I then had forged internals installed for reliability with near standard compression and later the charge cooled SSC kit. After a custom remap ( done at the same place that did the map for the air cooled tvs 1900 and on the same dyno ) it went from 430bhp to 495bhp using 98 ron pump fuel. I still did not use the car with the new set up so I can t comment on any difference in lap time etc but of course later I will add pictures and comments.
  13. On the 430 cup there is already fitted the red baffled oil pan as standard... Other than that I can argue about the oem pistons not consistent quality I had an engine failure on track on my 380 cup and after replacement with a new engine ( with some mods ) I had a piston failure that didn t make any engine damage. the standard pistons arent exactly built for track use with that power so I fitted forged pistons and conrods. Wiseco even recently revised it s forged piston design ( that was probably already ok ) for the toyota v6 to give more space between the segments as that s were the oem piston tend to break if stessed. To be fair there are a lot of 430 cup even with a 460 bhp remap going on track without problems so maybe with the watercooled supercharger and it s specific map the temperatures are lower and no eventual detonation etc...
  14. Hello Jack After installing the bosch abs what benefit did you find by removing the brake booster and fitting that BOE parts? Do you think you are faster without brake booster or just prefer the feeling? Of course I understand clearly the benefit of the bias adjuster in case you want to fine tune that... My Friend racing in the Lotus cup Italy that also own a cup R thinks without brake booster there is better modulation and while of course I m sure it s technically true I am used to drive aggressively on track fast cars but still with brake booster and in some way I like that easy pedal... Apart from that as already suggested I also find a real problem in track driving with the cup R and the standard abs system that sometimes quit braking and go into ice mode... You can get used to that and then adjust your driving but then you don t get the car at it s full potential... With the exige 380 cup the problem is less pronounced but I don t know if they made a slight software improvement as standard or if it s just because the cup r is faster and stiffer... Looking at the Komotec option it seem to be a good alternative to the Bosch motorsport ABS if you aren t looking for that last racing fine tuning but for something probably much better than std and Lotus specific ready to fit a a little cheaper. By looking at the specifications do you see any real downsides compared to the Bosch motorsport system?
  15. I use Redline MT 90 on my exige 380 cup and it s much better Those oils are specifically formulated to make synchronizers work better and that s what s effective in that kind of gearbox Frome Redline you can choose between MTL MT 85 or MT 90 depending on the use ( street or track ) and the outside temperatures This gearbox was not really intended for a sport car use so it s difficult to know what will be better for track use I still noticed after using the Redline MT 90 that after many aggressive laps on track it so at higher temperatures it once slightly crunched when shifting to 4th gear After that I replaced the complete clutch ( and brake ) fluid with castrol srf and it didn t make it again so it s really good to replace the clutch fluid with something better for track use Motul gear 300 is also a really good and recommended oil I never used something as 75w140 and would like to know if it s better for track use and still ok for the synchronizer
