This weekend the Spettacolo Sportivo- Zandvoort will take place. This yearly event is considered to be thé Alfa Romeo meeting in NL, with lots of special Alfa's and racing sessions of both the Squadra Italia and Alfa Romeo Challenge at the F1 Circuit Zandvoort. Because of the Corona regulations in NL, unfortenately this year no spectators but only participants are allowed to enter. On a positive note, we are happy that the event is not canceled completely like last year. The weather predictions for Saturday and Sunday are cloudy with some rain, so the track conditions can be tricky. But rain or no rain, Jasper Slop is prepared for battle! 👊😎 ... See MoreSee Less

Beginning of this month we worked at a beautiful Brera 1750 TBi. The owner was initially looking for a setup that is capable of ~300 hp with a K04 Stage 1 turbo. Later this was changed to a Stage 2 K04, as well as a front mount intercoolerkit, BMC airfilter in stock housing and 3" turbo back exhaust. Exhaust centerpipe and rear silencers still stock for the moment. Also the intake is not cleaned, something that is still at the todo list. Anyway, so what is the actual setup capable of? Stock output was 200 hp / 330 Nm, with the tune that was already in, the car dynoed 245 hp / 390 Nm. After H&S Corse did their magic this Brera is putting down an impressive 321 hp / 458 Nm! We are sure there's more potential if the other points are done, but for now the owner is very happy with this result! ... See MoreSee Less

Another 1750 TBi powered car in for an upgrade package. This time a beautiful Brera, a combination that is becoming quite rare.
This customer was looking for a 300+ hp setup, but he already had an aftermarket exhaust which is not suitable for this kind of output. The downpipe in question has a 3"/76mm diameter at the turbine, but decreases in diameter in a very short path so it can be fitted to a stock 60mm front pipe. This we see at more brands and it compromises the flow. So we cut off the front section and used it to create a new catless turbo back exhaust in 3" up to the center pipe. Ofcourse the tiny K03 turbo had to be replaced as well, so it made place for our new spec Stage 2 K04 turbo. Further, a front mount intercoolerkit was made, and a BMC air filter inside the stock airbox, with modified snorkel. So all the hardware for big numbers is done, let's wait and see what happens if the car gets a software tune and dyno test. Will keep you posted!
