Rotrex #2
(Or number 4 of the 4 cars that TTS have completed to date, to be exact)
I looked at getting a Comptech SC a *long* time ago but decided that my knowledge of engine management was insufficient to install it and run it safely. Since then I have concentrated on seeing how far I could take the car with NA mods, by increasing the power, reducing the weight and improving the cooling.
The Rotrex SC appealed to me because of its compact size and low weight (compared to the Comptech and Vortech SCs) but the deciding factor for going with this was that I could get the complete installation and done by TTS (who had previously did some work on one of my bikes and have a very good reputation for bike tuning) for a fixed price.
Prior to the SC install the car was outputting 166bhp rear wheel power (RWP) on TTS's dyno and after the initial installation the figure is now 254 RWP (there is still some work to be completed and I am sure this figure will increase).
The installation comprises of a Rotrex C3094 supercharger, 750cc injectors, upgraded fuel pump and the fuel/ignition timing is controlled by an AEM F/IC controller that piggybacks onto the OEM ECU. My non standard radiator meant that some of the pipe work needed to be customised to fit.
Richard at TTS (HORSEPOWER on S2ki) has had some problems with setting my car up on the dyno as the car was misfiring in VTEC. As my car is far from standard this was a bit tricky to diagnose but in the end the problem turned out to be a faulty AEM F/IC.
Right now the faulty AEM is still in the car and it is not adjusting the VTEC point which is still set by the ECU at 6500rmp. This won

Seems an excellent conversion

Your decision would have surprised me two years ago, but the dyno graphs for NA tuning make such unimpressive reading that I thought you'd turn to the dark side when the axial or the rotrex made it to the market (just as I would) 
How long have you have the silver and CF cam cover? Looks a very tidy engine bay

another one turned to the dark side!
