Well no matter what your gears, you will never see god.

Ah well.  I could wish eh.  Its too bad, I wonder how bad my CHD would run with that 3.32 R & P

my 94 AAZ Jetta is totally undergeared for its torque range and power.

dont wanna go for too high of a gear set.. then it will be counter-productive to your economy..

What a terrible problem to have.

I already have a tranny with .75 and would kill for the 400 rpms that a .68 would give.
My engine cruises with power to spare at any speed.
I usually drive around 125 kmph, and thats in the 3200 rpm range buzzin
.68 would put me at 2750, major difference
and in summer i run 17's with 205/40ZR17's and it gives about 5 klicks over the speedo on speed
and I still pull 800 k to a tank!



.75->.68 would drop you from 3200->2900 (about 10%).  What final drive are you running?  I put a 3.67 final drive gear set (replacing the stock 3.89) in my FN transaxle (0.71 5th) for about a 6% RPM drop.  I think that puts me at 2650RPM @ 70MPH w/ 185-70R13s (23.2" tall - your tires are about 23.4" tall) or at 125KPH(77.5MPH), about 2925RPM.

My tranny does run the 3.67 its a CHD code.
with a .75.  Sad thing is, last august the 5th went from a low oil situation ( output shaft seals leaked and started leakin faster than I could keep up with)!
Long story short I had a shop redo the transmission, all new bearings throughout and new 5th. I asked about puttin in a .71 and the guy there didn't know much about it (he was a great transmission tech, just not a VW junkie like us)
that woulda been the time to do it.
anywho I will keep drivin. I like to keep the rpm no higher than 3000.  just purrs
I love the whistle......

my GTI had 3.67 gears and a .75 fifth gear..

it would do right about 3000 @ 80 mph..

GTI's are great cars! I have been slowly converting my diesel Jetta to a GTD, basicallly a GTI with a diesel.
Slow process.

no, not even close to a GTI with a diesel, its still a jetta.. hahaha  ;D

kidding aside, when i build a TDI GTI, im never going to need another car as long as i live..  8)

i dunno what it is with me and my never ending love affair for mk2 GTIs..

my GTI also had an ACN (base model golf and jetta trans) transmixer swapped in it.. the 9A trans was retarded.. 3000 revs at 60 mph..

what else do I need? I am going full polyeurethene bushings all around.  a thicker front sway bar
no height difference but stiffer spring rates ( I hate lowered cars or jacked trucks) 

and aftermarket brakes and rotors, and 205ZR17 sticky yokohama's!

My biggest beef is the amount of movementthe engine does even with brand new VW sourced engine mounts all around, on the front one, I even shimmed the bottom bolt to put preload on it. and still moves like a bugger!
too much torque, need a spring/shock dogbone mount at the head to keep it tight!

Shiiiiiiiz...

ever looked at a mk1 engine move around? especially a mk1 engine with some ballz? they move ALOT..and my car has mostly brand new mounts..

mk2 engines dont hardly move compared to a mk1..

i drove my GTI to 350k miles, and it still had the stock engine mounts.. i didnt know how bad they were till i got a car with half that many miles..

if you dont want your engine to move, weld it in there, or take the rubber mounts out and use solid pieces of spun aluminum..

oh movement is good, don't get me wrong. and you can't compare a GTI to a diesel.
A billion times less harmonic vibrations
just need a upper torque limiting arm
my ol" 91 Lumina Z34 had one. had rubber bushings went right at the top.
any twist the engine does is power wasted!

I'll figure it out, already made my own load sensing timing advance off of the boost signal

on a VE pump? dont they already have an advance mechanism?

controlled by the governor, witch in turn is controlled by boost?

anyway, how did you do it?

and i wouldnt be worried about the dog bone mount, i would be more worried about somewhere sturdy enough to mount it.. passenger side shock tower is about the only choice you get, unless you went from the oil pan to the sub frame.. (hey, that sounds like a pretty good idea actually!)

the advance on a VE pump is controlled by the vane pump and housing pressure
on the newer VE pumps, the ones on the AAZ's with the solenoid (load dependant KB or whatever) they have a switch that turns timing advance off with throttle position (the solenoid just bypasses the pressure to the advance piston)
throttle position though doesn't really take into account load
so I used a switch from a NOS system (13 dollars) and tied it into my LDA feed
when the car is below 5 psi(light cruising) its quiet
as soon as you accelerate and hit 6psi the advance kicks in
its cool to hear it go on and off.
before i did it with the swithc on throttle position it would advance and make a lot of noise doin light city drivin

i *THINK* that you get better mileage with a little more advance..
