ok, i dunno how much better it is now, but i just started using it as more of a timer for 0-60 haha, looks to be around in 8-9 second range, it's hard to say since i have to drive at the same time, i'm sure you all understand, is that good? this is an 81 2 door jetta with no options and i turned the fuel screw in about half a turn to the right, and i have the boost pin turned to the deepest side and the star wheel down about 1.5-2 turns, it boost up to around 23 pounds. with a kkk turbo... lemme know thanks!

What was zero-60 times before you made the adjustments? Did you do each adjustment/mod separately than make a run? Just curious which mods give the most bang.
-
nah i have my car where i set it to performance and stock, i just have it "performance mode" none this is really mods, the only reason my boost is so high is because my wastegate is stuck shut. really all i did was adjust the fuel screw a tad and the boost pin tad, it takes a total of 5 minutes to do it all.

adjust the boost pin? you mean unscrew the top of the LDA, and turn it a TAD?
-
i have the boost pinned turned to the steepest side, the one which will allow the pin that rides on the boost pin to travel in the furthest
-
so with the BOV still active and boost controller set to 12 psi, will it help with anything right now?
-
i think the trapspeed is way off, but the et i think may be accurate as i got my 0-60 of 8-9 seconds, 10 at the most, and looking at other cars 0-60 and quarter mile times this seems to be in check
-
so what way do i turn the boost pin?
-
well theres a little indent on the front right side of the lda, and then there is a dot (like a dimple kinda) on the top of the plate that holds the diaphram to the pin, when the indent and the dot are lined up that's the side that gives the least fueling, so you turn the dirt so it faces the opposite way for max fuel, and anywhere inbetween to get it just right, when you have all the way to max, you'll feel that's just right :twisted: haha
-
oh yeah, and once you're done experimenting, you can make marks as to where you want it, i marked the max fuel part with a marker, and i put a mark on my star wheel so i know how many times i turned it. but this was all told to me by the hillfolk himself, i don't wanna take claim to something he shed on me.

to bad i can't even get the four corner flathead screws out, they damn tight! :evil:
-
tap on them with a smaller metal hammer a little bit, remember lightly, since you are hitting one of the most important parts of the motor. the steel screws going into the alumium usually corrodes and gets all stuck like that, kinda like a vw water pump setup, haha try and get one of those apart with out snapping the head off a bolt, for mine. if the hammer does work, do what i did before i discovered the hammer trick, and put the flat head in side ways so you can turn it like a wrench and apply alot more torque to the screw, but becare with that cause it can deform the screws

would applying a bit of heat help? couldn't hurt :)

i was gonna try a little WD-40.

The g-tech tends to do that. The reason is because the trap-speed is actually captured at the end of the 1/4, whereas at the track it's just before the finish line. So it is accurate, just measured differently. That's a really good time. Mine G-teched 0-60 in 19 seconds :(
Did the governer mod yet?
-
so what way do i turn the boost pin?

exxagerated,cause i cut mine,just note your pins' taper
wussy fuel setting
(http://img68.imageshack.us/img68/5848/hpim0441zt6.jpg)
lotsa fuel setting

excellent :lol:
so when and if i manage to get those four screws out, the pin just pulls right out and is turnable for the "proper" position? :P
-
yeah sometimes you have to spin it so that the other pin gets out of the way and you can pull it out, you can see the dent on the front of hill folks pump, i definetly wouldn't apply heat though
-
also, i still have yet to do a governor mod or anything, all i have an exhaust more fuel and more boost that's it.
-
Hi boys,whats the star wheel do? i can now see what you mean by turning the aneroid pin.
cheers Bert
-
well, hill folks pin is modefied, the star wheel adjusts the tension on the spring
-
not tons of heat... but a little soldering torch should do. or heck just drive the car... get it warm and that should suffice. Metal likes it when its all expanded. cold metal doesn't like to play nice
-
Can someone please tell how much turns on the starwheel did you made?...
I opened the lda today, turned the pin, and turned the starwheel for 1/2 turn clockwise...I followed the instructions from FAQ section...
But i didn't feel anything...I have adjusted wastegate on my K14, is blows aprox. 12 psi (stock 9 psi), and smoke didn't get noticeably worse...
Is it because i don't have IC, or the starwheel just needs to be turned more?
EDIT: I forgot to ask, do I make adjustments to the starwheel with LDA opened, and watch for the smoke or I have to drive the car each time I turn it?
-
you need to drive it so that you can build up the boost pressure.
-
and yeah, lda adjustments really don't make that big of a difference of a way the car drives until you get higher boost numbers. when i first started messing with it i was pretty disappointed, but with the lda adjusted and the power screw turned in it reall makes a difference as you can see :twisted:
it seems like alot of people are trying to do to their cars wha ti've done to mine since they've seen this thread, and honestly i advise against it since everything i've done is with out an egt. but i always watch my car and am easy on the pedal to avoid smoke. you really gotta be careful if you're doing it blind, and like i said i suggest against it.

last night i took the gtech out again, the first time i launched it way too hard and did some tire spinning, and had a 0-60 of 12 seconds haha. but then i left off and went for a drive to let everything cool down, then i came back and launched again, little too hard good bit of tire spin, but not the show i put on the first time, then i took off, when i shifted in second it didn't have quite as much umph as normal, and at the end of each gear i heard this screaming noise, like a turbo or something, and my tach went up over 5k real quick, then i realized my clutch was slipping like crazy, i was actually suprised my car had enough power to be doing that, i finished the quarter after i left off and ran an 18 something with a 10 second 0-60, not bad for a slipping clutch and letting off, oh well i guess i learned not to beat on a half assed clutch job... :oops:
but i guess i will be taking it very very easy until i can get a better clutch, i think i'm gonna turn everything back down... kind of a head ache, but i might have a diesel rabbit on the way, so i might just send my jetta to the painter and focus on my rabbit, or just try and let cars behind me for a little while
-
hehe last night i emptied my car of my tool box and stuff, left everything on it though that would be in for a factor car ie, spare tire and seats, and then had about 2.5 or more gallons of fuel. and grabbed my gtech and took off to my testing ground. checked all the roads for coppies. then lined up set the gtech and launched it hard in first gear, and those tires did not wanna hook, then i flew through the rest of the gear blah blah and did a 16.27 not too shabby i believe, for a stock motor with a tad more fueling and a closed wastegate doing 20-25psi. i need to get an egt lol. i am so dangerous

yeah man... egt gauge is cheap insurance if you've ever seen a diesel motor melt hehehe
what I noticed with my egt gauge when playing with the probe, is that the probe was glowing when it reached 1500F. I'd hate to imagine what 1600F would do to aluminum :shock: as in... it won't glow...
-
yeah yeah, i must watch but it doesn't smoke at all under boost so i am not too concerned, it smokes a bit till the turbo spools then it's all clear
-
mines the exact opposite, little smoke till turbo, then tons of smoke when its up to boost 8) .
Anyone one here have aftermarket pistons?

hmmm i find that smoke = oil burning :(
-
stock motor burns oil, needs turbo seal. building other motor though.
uses about 1 liter every 2 weeks (leaks mroe than it burns).
zero to 60= 2 hours
-
black smoke is diesel
blue smoke is oil
