I drove down to KomoTec this week to originally have the stage 2 installed, which should give 410 Hp. Well, in the end it became a bit more.
Key element of Stage 2 is a larger pulley for the supercharger, increasing boost by 0.1 bar. The package has been around a while for the Exige V6, but installation in the Evora is much more complex as there is no room for access. Well, KomoTec has meanwhile found a solution by lowering the engine sufficiently that they can gain access with a special tool to tighten the pulley after mounting. All this makes the installation a much more viable and less costly option to the engine out alternative.:clap:
After installation Daniel put the car on the dyno, only to discover that the BOE CAI I had installed is significantly limiting power
(see her), so we went through the options. Peak power was only 379 Hp, far below the expected 410 Hp. :shrug:
In this power class airflow becomes the key issue and any restriction has a massive impact. Fortunately KomoTec has also developed a custom air intake, which they have again been testing on several Exige V6. This unit uses a massive air filter of 20 cm input diameter and 30 cm filter length (see photo).
We put the prototype in the Evora and immediately got around 429 HP, sufficient to convince me to take some more money out of my pocket. -poke- Some software tweaks and we peaked out at 439 Hp, which is when we stopped. Just take a look at the almost flat torque between 3500 and 7000 rpm. :clap:
This new stuff is still under final development, the airbox is a prototype and still needs a final mounting and air ducting solution (we reused the BOE saddle).
One final word to anyone considering Komotec stage 1, 2 or above: keep away from the BOE airbox, you're just wasting money and power
