i did all the adjustments recommended... except the boost pin thing. why? because i don't have one. i have a 1.9 TD. 1st gear lots of smoke, after that... nothing. i loose power after 3,800 RPM. i think i don't have enough fuel, i can hear the turbo. i don't know how else to increase fuel at high RPM.
my question here is... who sells the aneroid pin ???
thanks...
-
you can make your own,or i thought one was avalable from germany or somethin
i saw also that bully dog makes one too,but i think its a bigger pin,so it wont work,ive got a spare 4b pump,and its' pin doesnt fit my vw pump
im thinkin someone on here makes one
i made mine from a spare one,i can set it on max fuel,or turn it around for max economy
max power setting

i carry a little tool pack in my car and can turn up my pump in minutes with it
actually i ride around with it turned up most of the time :roll:

Nice ....... i actually seen your setup awhile back. I have search the site for the pins. i know lots of people have it, but they never mentioned where to get one. i also know that some people buy the whole pump and swap parts... i checked on ebay and there are lots of different veriation of the same pump, so i was not sure which one. i have never seen the inside of the pump and don't know enough about the pump to make the pin. i am searching for parts now... if i can't find one...then i will consider making one. The funny thing is... junkyard has a lot of VW, but never seen a diesel there.
thanks again for the help... anything is apreciated

1.9's have boost pins unless urs is an ecodiesel, it's just that there pins suck, if i had a 1.9 and ic ouldn't find a 1.6 pin i would just do what blake did to his 1.6 pin...
-
my friend picked up an aftermarket HP boost pin in germany for me. It has a narrow and steep profile. I put it in a M-tdi and it made a big difference over the old fiat td pin which BTW is steeper than a vw. Best $75 spent...power wise.
-
75 bucks, ouch
-
when you take into account how much work it is to make a pin properly...$75 is a good deal. My turbo spools up much faster now..makes 23psi very quickly.
-
i "borrowed" the profile of a "bully dog" pin at work,others may not be as lucky as me :roll:
besides when i wanna "turn it down",i just rotate it to a stock spot
i usually leave the plastic washer off of the pin,and i have my starwheel fully bottomed,its probably about 2 turns to do that

I tried to do the pin rotation thing but it looks like the profile is the same all around the pin, am I supposed to cut my own profile on the pin?
-
can anyone give me the measurement for the pin's profile? when it starts to when it ends... can't be cutting profile if i don't know where to cut.
also... for the 1.9 td what will keep the pin from turning back. the 1.6L have a nut and screw to hold the pin in place, 1.9L don't
i don't know if the dealer will sell the top part of the 1.6L pump??
thanks for the help guys
-
sorry....i don't think that i was clear in my request. i just need the lenght from the top of the cone to the bottom... i want to know how long it is. i perfer to know the length of the original from the 1.6.
-
lookat your orig pin,you will see a little scratch on its length where it was normally riding,thats its travel area,and you get more travel if you remove the plastic washer
maybe this helps??

thank you all.... will do this mod in the week end
-
in the weekend, do it now it takes 5 minutes
-
I'm still curious...
I have to make the curve on the pin, dont I?
-
yea i just make the ramp "steeper"
curve it up towards the end of the travel
that way it doesnt affect the fueling at low boost levels too much,thatll affect your mileage ,or you can start out mild,and keep grinding to your preference
-
The boost pin mod is a serious must...
i took off about 25% maybe less to try, it feels amazing - i think the wheather makes a difference also, it was about 15 degrees celcius when i tested it. the temp goes up really fast also, but not over heating. what percentage did u guys take off?
hillfolk'r: - i know u went hardcore... good for u bro ! ur pin looks like it's aluminum??
one more question... did u guys "de-cat" to keep turbo temps down??
-
mine was a "factory "pin that i modified
i would think you would wanna remove the cat
when i had my old idi td,i had a 2.5 inch homemade dp(looks like PP's),and a 2.5 inch straight pipe exhaust that exited in front of the left wheel
this was from waterfest 03

i had a slightly modified pin in there,but not as radical as it is now
that was a 9mm pump too,and my best et was 15.79
-
So...
were to you buy a boost pin then?
Because I need my "old" one because of emission laws 1 time per year..
Regards, Klang
-
that's the best part, all you gotta do is turn the boost pin around to side you didn't mess with, and bam stock lda fueling, or you could just run the starwheel up real high so the springs really tight, kind of make it in active.
-
aaah....
then I have some work to do tomorrow..
And I happen to have acess to a dyno (or whatever its called in english, you se how much BHP you have :P )...
So I'm gonna give it a go..
What is the pin made of?
Alu. Or steel?
Regards,
Klang
-
some nasty hard steel,you arent gonna use a hand file,you need a grinding wheel,i did mine with my lil dremel tool,you may be able to carefully do it on a bench grinder
after i rough ground it i used sandpaper on my dremel :wink: to polish the ground area so it was somewhat smooth
-
hillfolk'r - i agree... u really have to make the grind surface really smooth, because the fueling rod will have trouble riding on the grinded surface area.
i used a carbide grinder to smooth it, works super... then i apply grease to the surface. Can't say enough about this mod... A MUST for speed. i will remove the cat this week end
Klang - i have emissions too... that's why the other side of the pins is left alone. so when emission comes... turn the pin = no fuel... just air
what about the spring rate??? i don't have a star wheel also. i have a breather... my pin area is full of fuel, so it's pissing out of the breather
i will try to post some pics in the near future
