Stage I TVS Super Charger plus EFI Standalone Engine Management for 2ZZ Elise/Exige, 275whp/175wtq: $7,200
The BOE TVS Supercharger system is the best and most comprehensive forced induction system on the market. We designed it with the track in mind first. However, it works great as a street solution as well! Throttle response is instantaneous. There's no turbo lag and it works perfectly within it's optimum efficiency range unlike other supercharger systems on the market that utilize the MP62 blower.

The kit includes everything you need for installation:
BOE TVS Dyno
Below dyno is on about 10psi boost, 1320 TVS Supercharger, BOE Tune, and on 91 pump gas. The engine is equipped with KN cone-type air filter, free flowing exhaust and Weapon R headers.
EFI Engine Management
We utilize a complete standalone EMS (Engine Management System) designed and developed in concert with DRS and EFI Technologies. The integration to this EMS easier than you might think. We'll build the harness for you on an exchange basis or we'll modify your existing harness within a 72 hour turn around. That means to integrate a race oriented EMS into your car, you'll only have to solder or crimp 3 connections! The modification to the harness in reversible back to running on the OE ECU in about 2 minutes thanks to our our Deutsch connector intercept connectors.
Drivability is OEM like with super smooth throttle response and a nice lean cruise for good fuel economy. You do not have to be a "tuner" to run this system, as our base maps are typically ready to go right out of the box. However, with so much flexibility right at your finger tips, we recommend to our clients to have an open mind about tweaking their tunes for the most ideal redlines, cam shift points, etc to meet the needs of their specific application. We're happy to help tweak tunes over the phone and email as well.
BOE is Lotus Supercharging: Background
At BOE, track bred performance is what we're all about. Everything we create is designed first for the demands of the race track and second for the street driver.
The Old: M62 Roots Blower
When it comes to increasing the output of the 2ZZ-GE, forced induction is a great way to go about it. There are various ways to go about adding forced induction and Super Charging the 2ZZ engine found in S111 Elise/Exige is nothing new. Greddy has had a kit that the Celica GTS community has been using for years using the old M62 Eaton roots type blower.
The Greddy Kit components were not well thought out and constructed poorly. In our first generation of the Lotus version of the Greddy kit, we simply redesigned and machined the Greddy parts to be much stronger which has vastly improved the kit for Lotus and Celica GTS cars all over the world.
We have now completely rethought the Greddy M62 kit for the Lotus community in our next generation of M62 based supercharger systems. The new generation is specifically designed for the Lotus and is much stronger and more robust than any of the previous Greddy based installation kits that have been produced. It now incorporates a support for the blower nose among other imporvements designed specifically for the setup to live in the harshest environments--- on the race track! To date, we have supplied well over 200 Lotus supercharger kits primarly through Sector 111 and Blackwatch Racing.
While the M62 blower is OK for the sub 230whp user, it is inadequate to be pushed much further if you expect it to live on the track. Careful examination of the M62 compressor map will show that the blower is simply improperly sized for for track use, as the demands on the blower are pushed beyond the limits Eaton ever intended for it to be used.
The NEW: TVS Supercharging the Lotus- The Next Generation In Supercharging!
We are the first in the world to successfully marry the newest blower technology from Eaton and Harrop to a Lotus. The improvements in efficiency are fantastic.
To date we have built dozens of Lotus race cars with our TVS technology, which are running hard across the world.
The first stage of this system does not use an intercooler. The blower is so efficient, that it simply does not need one to sustain about 280whp on the race track on 91 octane gas. For power demands in excess of 280whp, an intercooler, better fuel, or water injection is required and is found on our Stage II system available in Summer 2010 (note that a engine internals need upgrading for Stage II).
With this type of power, these cars absolutely fly!
