Bang Boom Last Sunday it was finally time for the first trackday for me and new family member 944 turbo 1987. A little nervous before the first run with 944án I went slowly out of the track . Warmed the tires and the car in about 2 laps . When I would get up in the pace of 90-100 % as the car begins BE AWKWARD . I feel that the car is completely decrepit like if you turned off the key Böööööööööööö , or not getting any fuel. After Boooo so slamming it significantly. Crackers followed by a proper cloud with BLACK smoke, the car jerks a little and get full power again . To start with booo again . I felt that it came with the curves and the G forces , maybe some loose connection but it might have to be stepped on / off the gas quite fast at track days. After the first round I was picking apart the fuel pump connector ( behind the right rear wheel ) and smeared it with contact grease . Also had the fuel relay in the fuse box in order to remove any oxide on the pins. The tank filled ¾ After the second round of the track where I think the problems came more often and more frequent , eg completely undrivable so I went out into the depot where the car stopped itself from low revs. Started the car after 15sec no problem but the heat gauge show max temp. I go when out on the road outside the racetrack to cool the car for about 5km . No problem with booooo all during quiet roading . Tests accelerating 2-3-4 to 6500rpm no problem, no Booo . The car is not completely original Reground cam and cam housing . Area951 chip KX400 turbocharger . mahle pistons Not to begin with hysterical troubleshooting i now consults you , knowledgeable Porsche 944 people for help to get this nice car on the track again ! Anybody have any tips ideas, I would be EXTREMELY grateful. Sincerely Henrik
