DRIVETRAIN UPGRADES

Check Compatibility

Elise: 08 – Current

Unlike modern turbo engines, supercharged engines such as the 2ZR found in the Lotus Elise, still respond well to what we would call “classic” exhaust manifold tuning, such as optimised runner design and nicely detailed collectors, to give their best.  Unfortunately, most OEM designs fall short of the ideal because of the constraints placed upon their engineers, most noticeably production cost.
Our exhaust manifold design has been designed specifically to address any performance-related issues and in combination with our cold air induction kit it provides a noticeable improvement in engine breathing.  To take advantage of that, our engineers also reflash the ECU with a custom tune to ensure that optimal driveability, performance and reliability are delivered.
Key features of the Level 1 kit include:
•    Exhaust manifold designed with optimal runner lengths and diameters to maximise the inherent potential of the 2ZR engine.
•    Refined collector design for improved exhaust gas flow, which mates to standard downpipe and catalyst.
•    Exhaust manifold manufactured from T409 stainless steel, with CNC mandrel bends and robotic welds for consistent high quality and perfect fit every time.
•    Ceramic coating of exhaust manifold to reduce engine bay temperature and improve looks.
•    Cold air induction kit featuring CNC machined and welded MAF sensor mount, the necessary silicone joining pieces and clamps, a lightweight aluminium pipe and HKS, high-performance filter.
•    Induction kit promotes laminar flow upstream of the supercharger, improving MAF sensor accuracy and reducing airflow restriction.
•    Slight reduction in weight over standard parts that are replaced.
•    Power and torque improved throughout the rev range with a peak of 245.5bhp (vs. 220 as standard).

SSC TVS1900 SUPERCHARGER UPGRADE

Check Compatibility

Exige: 12 – current

Evora: 09 – current

AVAILABLE ON LOTUS EVORA AND LOTUS EXIGE

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.

THE KIT FEATURES:

  • Harrop TVS1900 Supercharger
  • CNC machined inlet manifold and throttle body adapters
  • Gatorback Drive Belt
  • SSC CNC machined MAF sensor mount
  • Air intake with SSC Silicone, Aluminium Pipe & HKS performance air filter
  • OBDII Flash tool to update the tune

CHARGE COOLED TVS1900 SUPERCHARGER KIT FOR LOTUS EXIGE V6

Check Compatibility

Exige: 12 – current

AVAILABLE ON LOTUS EXIGE

Hofmann’s is proud to offer the innovative TVS1900 Supercharger Kit to suit the Toyota 2GR-FE 3.5L V6 engine found in the Lotus Exige S. This inverted positive displacement supercharger kit is engineered and manufactured by Harrop to OEM standards using Eaton R1900 TVS Technology. Featuring superior packaging and performance efficiency, this kit is available as both a Tuner Kit or Complete Kit with a supplied calibration, offering the Lotus Exige chassis the power and torque enhancement to maximise it’s very high-performance potential.

Installation is of OE appearance and fitment, leveraged from designing and supplying OE supercharger programs.

Key Features and Kit Components:

 

  • Harrop TVS1900 Supercharger
  • Inverted Supercharger design
  • Integrated and Intercooled Supercharger bypass system
  • Large, high-density intercooler core (304 x 180 x 73mm) using the latest core configuration technology
  • Throttle body adaptor utilising either 71mm or 77mm variants
  • Standard Supercharger pulley is 7PK 85mm – available in 5mm increments
  • Calibration for stock engine installations is available at an additional cost via file server deployment utilising a Tactrix Tune deployment tool

Additional Information

Although we keep to the prices above as strictly as possible we do occasionally run into problems when a car is particularly corroded or in poor condition and needs extra time spent on remedial work. If this is the case we will always report the problem to the customer immediately so they can choose how they would like us to progress with the repairs.

Where bolts and washers are removed to complete the set up procedure we always replace with new. For example camber optimisation requires the removal of the upright bolts which would be replaced with new 10.9 grade cap heads bolts and the threads in the upright cleaned where necessary. Where appropriate copper slip, anti corrosion compound, or locktite are used in the rebuild.
