Supercharger Upgrades



The factory fitted TVS 1320 supercharger is on the limit of it’s operating efficiency window on the V6 Exige. On a 25.7 deg ambient air temperature day we logged the intake air temperatures and pressures of a stock V6 and found the intake air temperatures regularly hit over 90 degrees Celsius and peaked at 97deg within 2 laps. Without any provision for a cooling system this means the engine management system is reducing engine power through reductions in ignition timing and addition of extra fuel just to keep everything safe. Any further reduction in pulley size would generate some extra boost pressure but even more heat again meaning the performance gain will be very short lived and potentially harmful to the engine.

Hofmanns are sole UK distributor for these kits which are developed by Australian company SimplySportscars in conjunction with Harrop Engineering, who manufacture the Lotus OEM TVS1320 supercharger. This kit is a direct bolt on replacement using the TVS1900 charger. This charger has a significantly higher capacity, allowing us to use a bigger pulley to produce higher pressures and achieve lower intake air temperatures than the OEM set up.
