What does this do? On my Cummins it equals more power to adjust it if I remember correctly. Never did. Stupid question, but what is the effect on a N/A engine if any? Any negative results possible? I really like my VW and don't want it to die. It is a 81 1.6 diesel btw.
on the VW rotary pump.. adjusting that screw (within reason) adjusts how much fuel is at what position the pedal sits. So to make that understandable.. say for ***s and giggles that stock at half throttle it is injecting enough fuel to run the engine at 2500rpm.. turning that screw and increasing the amount of fuel per pedal position, will increase how much fuel is injected.. So now instead of having the fuel for 2500 you have enough fuel for 2900rpm, yet still at half throttle. If you can get your engine to breathe well enough to burn all this extra fuel.. you have.. in theory
Free Power 
However.. with an N/a get a Pyrometer in there before you start messing around with fueling too much.. or you WILL melt stuff lol
Open up the exhaust, Open up the intake (LET IT BREATHE!!), turn the fuel until you get a good light haze at WOT.. then back it off a bit, and you will remain in the safe levels, and your car will love you for it
It will surely liven the little guy up Lol
or........
slap a vnt on there and go like hell and never get high EGT's
Is that your answer to all life's problems Kevin? a VNT? lmao
First off, what is a VNT? My exhuast is a 2" straight pipe to a cherrybomb muffler. As far as intake, all I've done is cut a bigger opening in the air filter housing. This truck never had the hose like I've seen on others. I also hope to put a full gauge cluster on as soon as the wife isn't looking. I've already had to replace the brand new engine once due to the incompetence of the previous owner. He converted it to a diesel and assembled the engine himself (purportedly) but forgot little things like torquing down the bolts. Consequently, I lost #4 connecting rod on I-5.
VNT is just a shortform for variable geometry turbo
Is that your answer to all life's problems Kevin? a VNT? lmao
yes, that is the answer to all of lifes complicated problems. VNT's fix ANYTHING!
lmao
if you cant put a VNT on there to fix it, its not worth fixing. haha.
now i just wish i could get a 5 cylinder VNT turbo like the 1749VA, but bigger.
