Maxi_z Posted July 13, 2021 Report Share Posted July 13, 2021 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 1 Quote Link to comment Share on other sites More sharing options...
steveoexige Posted August 2, 2021 Report Share Posted August 2, 2021 Who did the work? Last year 247 Motorsport upgraded my TVS1900 to chargecooled and noticed that the belt alignment was slightly out. They had to machine the pulley adjuster to fit. Probably worth giving them a call.

DangerousDave Posted August 28, 2021 Report Share Posted August 28, 2021 Thats the problem with aftermarket blowers they always break belts. Quote Link to comment Share on other sites More sharing options...
Maxi_z Posted September 3, 2021 Author Report Share Posted September 3, 2021 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 Quote Link to comment Share on other sites More sharing options...
Mattmahope Posted September 3, 2021 Report Share Posted September 3, 2021 My belt broke on my first drive with the TVS1900 kit fitted. Komotec said the pulleys were not perfectly aligned. They fixed it and I have had no problems since. Been using it hard on road and track for over a year now. Quote Link to comment Share on other sites More sharing options...

Thats interesting Do you know where I can look at the alignment procedure and if it requires special tools? Quote Link to comment Share on other sites More sharing options...

Or did they just fix that problem later? Quote Link to comment Share on other sites More sharing options...
Mattmahope Posted September 13, 2021 Report Share Posted September 13, 2021 Correct. I have the TVS1900 water cooled supercharger which I ordered directly from Harrop and which was fitted by Komotec with all their auxiliary kit. Quote Link to comment Share on other sites More sharing options...
