Thanks, David David Cook Red '86 Cabriolet Diesel Powered Red '90 g60 Corrado Brown and White '78 Westy Campmobile "Bear" and others in various states of disrepair Pictures here: community.webshots.com/user/superdave5599 Hagar sez : Hillbilly Tuning is a misnomer ------the TUNING is a highly sophisticated , scientific approach to getting a Diesel (VW) to perform. ---To your individual specifications. In Hagars case I go for a complete and perfect combustion cycle ----NOT MAX miles or MAX power. If you get 43 miles on a gallon ? ----do NOT touch a thing . you are A OK. But the Hillbilly TUNING was a very complex system --mostly aimed at EXPERIMENTERS or perfectionist like Gavrik Peterson. -----it is mainly a way of compensating for WEAR in old Rabbits.---- The normal TIMING system will NOT work if things are worn. ---So what we do is this we TUNE for performance ----any Performance you like ---BUT you must know how to do it. This procedure is mainly aimed at OLD Rabbits ---1.5L NA 1.6 L NA and turbos. and it will do just fine on ECO models.-----If you are a physics type ---you will have NO problems following these procedures. Here is a summary of the procedures. : First the FUEL ---do a rudimentary test look up Fuel 101.---then the Pressure in pump ----those two are the worst of all problems.-----then we go on to Compression ----and setting of Injectors ---I can go on all night ----but you must go study diesel Management by Robert BOSCH. ----the Fueling and idling adjustments are important and ----- one thing I learned from Loren -----get NEW NOZZLES .----yes old nozzles can be cleaned ----I did it ---but in the tester ? a glass eye looks good ? JA but it sees nothing.------HE was so right. Part of Hillbilly tuning is setting the pressure in each injector according to condition of THAT cylinder. So if you set them all the same ? --BUT the compression is not all the same ? JA you do get less than optimum performance. ---JA ? ---bet your sweet ass. So you all see this is a very scientific way of going about it.-----NO NOT needed if transportation is ALL you want.-----BUT I Hagar is an experimenter. ----and signing off let me say that moving the pump or the Fueling screw ? a pencil line ? ---- BULL ---you got to get down to half a line.-----sure feels good when that Piano is tuned --right on --EH ? -JA ? -----TUNING is a good word ----in a while you can listen to that Diesel ---and you will know when she sounds happy-----NO SHIT. I am quoting Feyman -----science --is Observe -Reason-Experiment. ---so Hagar is a homemade scientist. Hagar. PS : sure like those Feymans Lectures on Physics.
