Hi Guys ,

An update . I visited my old mechanic whose already retired due to renal failure. I consulted him regarding loosing power at high speeds. He advised me to replace the spark plugs . Good thing I still had the NGK BP8ES I brought 2013 from PelicanParts . I also tried to tighten / grip of the Wutrin red round relay thats made in China , the pair that supplies the fuel pumps. I also replaced the 25 amp fuse of the fuel pumps. I tightened the screws of the terminal blocks that holds the wire/ fuses . The son of my old mechanic arrived and he replaced all spark plugs using the Porsche special tool w/c made the job easy for him. He said w/o that tool he would have hard time . He examine the old plugs ( Bosch Super W5 ) and he noted the 5 plugs has a lean mixture burn , while the other one from the left bank had a bad sooth and looks like its on its way out. I have not replaced the spark plugs since I bought the car in 2008 . But I change the engine oil and brake fluids annually and the gear oil every other year .
We tested the car in the freeway and it easily hit 110 MPH w/o loosing power nor stumble / stutter . It seems we have solved the problem but , the mechanic is dropping by today to check the burn characterictics of the NGK plugs . If its still lean we plan to adjust the CO . Whats the normal CO for a stock 89 911 turbo .

Thanks in advance ,

If you have boost but are loosing power, sounds like a fuel starvation issue. You would hear or feel a missing cylinder if it was ignition.

Hi ,

T77911S , Iíve not replaced the rotor yet , I will order one from our sponsor.
I agree w/ you Ficke , thatís why Iím asking myself if it was the new spark plugs or my tightening / securing the 2 relays & 25 amp fuse of the fuel pump w/c solve the problem
