Best Wishes 2024. Thanks Fred, helpful response as expected. -- my 1 new FPD ( from ADAPT Motorsport, Switzerland) has made a difference, engine more responsive and maybe cleaner running at idle speed too. These ADAPT FPD s look like a piece of good engineering.
I may have to force myself to replace the other one and the Regulator too. Its only money..... and a good deal less than OEM Bosch product.

Hi Fred, greetings from UK, did not want to start a big 'debate' on this so thought you, guru & process engineer, might comment:
On the 928 S4 like ours 1 FPR, 2 Dampers.
fuel is a liquid so fuel pressure though out the fuel rails is same, hence 1 FPR . why do we have 2 Fuel Pressure Dampers. Only need one ? ( 1 working one that is). Peter

Tony,

Great to hear from you. I had a problem accessing Rennlist for some mysterious reason- I think it was a problem with our provider blocking the Rnnlist server for some weird reason. I am definitely in upgrade mentality but have wondered whether to stick with the auto or start from scratch with a mamual tranny model imported from the Stats or Europe. I have always felt the auto model is killed but lack of suitable torque to pull it but with a TS I suspect all that changes dramatically. Appreciate your views on how your car copes with cooling espeically as you are in a warm climate zone during summer.
Trust the airline business is still keeping you afloat depsite the current troubles.

Regards and best wishes

Fred

Hi Fred, good to hear from you! The car is going strong! If you search the forum you will see i just did a leakdown on the motor and it is still VERY healthy! Im putting out over 440rwhp and 400 rwtq as of a dyno a couple of years ago. I spent last summer with the entire engine and driveline out of the car just doing a complete clean up and restoration of sorts underneath...tranny lines...converter bearings...rod bearings..oil pan stud and gasket etc etc. It all started with a simple broken supercharger belt....a month later the car was gutted underneath!! hahaha...you know, one of those "while your at it things" got out of hand !! Took some time and patience but i now have a very tight and DRY car all around! No leaks...or hot oily smell from the engine etc etc. Get your self one of DR's kits or even Tim Murphys and you will be delighted how it transforms the car!
Take care!
