We had a special visitor down at GCAP. Porsche Carrera GT. A timeless supercar. This one is owned by a customer of ours who lives in Dubai, buts visits the UK 5-6 weeks a year. He always pops down every year to find a little job for us to do on one of his crazy fleet of vehicles! These fetch anywhere between £680,000-£850,000 these days!

BMW X3 M40i PPF in for a stage 1 tune. Standard 360bhp / 369lbft Tuned 425bhp / 460lbft -Vmax removal -Sports display recalibrated This car is brand new, tipping its hat at just over 1300miles. The customer is going to enjoy the new lease of power then we will develop our stage 2 package for this vehicle - including PPF delete to help bring back the noise that is lost on these PPF versions and unlock some crackles on over run. Is this one of the first to be tuned in the country? (Front grills missing in the photo as currently being painted gloss black).

A great little project we have been working on this week. Focus Cloud approached us to help build them a little pocket rocket for the track. The owner of the company puts on track days for the company's clients and staff members. There, they get to take out a fleet of vehicles owned by Focus Cloud. Amongst them is a 1000bhp GTR and a Caterham. In order to provide a gentle introduction into track racing, Focus Cloud asked us to make the Corsa VXR fun and brisk around the track, so the clients can get used to track driving before stepping up to the next vehicle in a different class. Below is the spec of the vehicle after some GCAP tlc: - Full forged internal engine build - Turbo Dynamics K03 hybrid turbo - Turbosmart actuator - Turbosmart recirc - Turbo back exhaust system - AIRTEC Motorsport FMIC - 615cc injectors - ASNU Fuel Injection uprated pump - JS Performance coolant hose kit - DNA Racing Components adjustable RARB - DNA Racing Components boot strut - Adjustable coilovers - Quaife Engineering LSD - J hook discs all round - EBC Brakes yellow stuff pads - TOYO TIRES R888r tyres - GCAP high/low boost switch - 80mm MAF - SM Tuning custom stage 4 software This little pocket rocket now boast 280bhp / 285lbft and handles great. We also addressed multiple boost, water and oil leaks and a charging issue to ensure everything was tip top. I'm sure Focus Cloud will be back for more (we have a heap of recommendations chassis wise to make it handle even better), but for now a great little car to throw around for fun and learn the ropes!

A neat little button we installed in Doug's famous green machine - switchable high and low boost control. We have set this up so the car will provide low boost on start up. This allows for a more controlled and relaxed drive delivering circa 330bhp. At the press of this button (and some red illumination) the car delivers full boost bumping the power back up to 430bhp for the more spirited drive! The Corsa VXR does not have a sport button and Doug was always keen to have something similar, whether it be limiting boost or offering different throttle response like the Astra counterpart. We came up with this solution which has bode well and even has a nicely laser engraved button with an apt Nurburgring logo for a Nurburgring edition vehicle!
