                                                                           I really do love my 911.... But just look at her.... Handles great too!!


Porsche 968CS, built in 2008 from an original '94 Clubsport. Continuously upgraded from 2009 to 2012 and garaged after the latest updates.

Completely custom rebuilt engine (see specs below) with Rotrex C30 supercharger. Engine tuned by TVS engineering in Varsselveld: www.tvsengineering.nl  specialist in Rotrex supercharged engines. The engine ran for a few testing hours and two racing days (aprox 80 laps) after its built.

Onboard at her last race at Zandvoort, a fierce battle with a Porsche 996 GT3 MKII, losing a little on the straights and gaining in the corners:

 This is how I first saw her...
Covered in dust and far from ready
but already extremely beautiful!


                      So I took her home...                                              ... and found out she needed
                                                                                                       a lot of love and attention.

The intercooler was to small
and Henny was not happy with the plumbing.
So he installed this one. 

 Air temperature sensors we fitted before and after the intercooler.
