Title: How Fast can you get your 1.6 N/A to go in 4th gear?
Post by: GIDDY_UP_GO on January 23, 2009, 09:03:45 pm
I have a 1986 Golf 2 door hatchback with a 1.6 N/A diesel coupled to a 5 speed tranny. Today I was in a hurry and got it up to 70 m.p.h. before shifting into 5th gear. I don't have a tach, but she was definately talking to me! :)

Anyone else ever get one up that fast in 4th.......?

Don't know but my 71 beetle will bury the speedo [90 mph] in third.

Not sure.  I know that I got it to 85mph in 5th gear once (down hill).  I have the original GTI transmission, which gives a bit lower rpm than the diesel transmissions do (oddly... you'd think it would be the other way round, but look at the ratios....)

Yeah, 85mph is about all I can get outta my little 1.6 n/a too. It must be the absolute perfect conditions though. No head wind, no hill, and an absolute straight road for miles! :)

I can easily hit 140 in my NA. It'll go a lot further but I'm afraid of speeding tickets.

I also have a AGS but I'm swapping in a ACN I think.

Sunday I had the jetta at 70 in 4th at 4000 rpm and then 75, rpms at just a shade under 4300.  I usually shift to fifth at 65 - 70 mph.

I got an ACN behind the 1.6 in my 86 jetta.  I can easily hit 70 in fourth.  I LOVE MY ACN.  used to have the gp four speed. :-[

The '84 rabbit owners manual says: use 4th gear between 28mph and top speed, E gear (5th) between 36mph and top speed.

with a stock governor, and a GC 4 speed, i could go 83 mph, down hill with a tail wind. or 83 on flat ground. or 83 up a steep hill. now with my governor shimmed up and an AUG close ratio trans w/ 3.67 final, it will go ATLEAST 125 mph on flat ground. thats all the harder ive gotten to run it so far. im going to be getting an ACN for it before too long. the .75 fifth and 3.67 will be nice.

still have no idea how many rpms my car turns.. no tacho.

no, i just looked down at my speedo. i have a 140 mph cluster in there. and i picked up my ACN the other day. its in my gas GTI right now, but its gonna get a diesel bolted to it in the near future. the speed calc said 5500 RPMS @ 125 mph. witch works out to be pretty much right. i knew that the trans turned right about 5000 at 105 mph in my jetta. i doubt it would go 125 if i didnt have the BR 70-13 tires on there, they are pretty tall, like 4 inches taller than a 195/60. its gonna be 4673 @ 125 with the ACN trans in there.

going from a top speed of 83 to an unknown top speed is pretty decent. i havent found a long enough straight stretch to really open er up yet.

i had my 400k n/a up to 90 in 4th and it still had some left.

4 speeds with no overdrive are retarded tho. i had one of those. when i went to the 5 speed, my car really came alive. it was really sluggish with the 4 spd, the turbo fell off boost every shift. with the 5 speed, i can maintain 10 psi between shifts.

They are :)  I have a 5 speed FN, post just asked for top speed in fourth :P so i thought i'd post up lol

fifth is definitely a cruiser with the stock motor. it will come alive when i open up the intake and exhaust this spring and mess around a little bit with the governor.

Post by: Rabbit on Roids on January 21, 2010, 12:05:09 pm
any of the .75 or .71 equipped transmissions do nicely while cruisin. either 4 or 5 speed, they both came equipped with super high over drives. and those were nice.

sadly they aren't really usable for anything but cruising :P  1-4 hot rod it and then slip in to fifth and sip the fuel :)

I hope you're not talking about the ACN that rabbit on roids is talking about. ::)  my motor came out out a rabbit that had a gp 4 speed and went into a mk2 jetta with the ACN behind it, and the difference is BEYOND night and day through each gear.  my little lady thought I had a completely different motor after the swap ;D.  and remember that mk2 is a few hundred pounds heavier :-*

no Mclovin' ( LOL ) I was talking about an FN trans, and I was referring to how the .71 5th gears aren't much good for anything but cruising. ;)

ASF, AON, ACN, ACL (8v)    3.67    3.45    1.94    1.37    1.03    0.75  spins 2537 in 5th at 110kmh
FN, FF, FH, FJ (from '81)    3.89    3.45    1.94    1.29    0.91    0.71  spins 2545 in 5th at 110kmh

With the slight differences in the 3-5 gears, but the different FD gearing.. these transmissions would feel pretty much identical I would think. Having slightly shorter gears, but a slightly longer FD.. They would both be nice.

I think a FUN transmission would be a trans with a 4.25 w/0.71 5th or a 3.94 w/0.75 5th..

Or this 4spd GY (3+E 8/82-7/84)    4.17    3.45    1.75    1.06    0.71

 :-* lol

i wanna play with one of these some day when i have some serious horsepower that i think i need to abuse a tranny with. although, first gear may be a bit too low with the 4.20:1 fd ratio, i always wondered what 420 r&p sets came in, i guess i know now.

you can only do 83-85 w/ a GC trans wound to the bolts.. unless you modified/removed the gov..

my car will bury the speedo needle on the ODO reset stick with a GC.. and it does it quick too.

My 1986 Jetta. Pretty easily and when shifting to 5th at that speed 5th has amazing pickup. Nothing like the gutless it is at 45mph in 5th trying to go faster on level ground

45 with my AGS that has 3.667 R&P says 1772 for 45mph
for 100mph it says 3939
I need an intercooler, I garantee I could wrap the speedo now at 120, but it may take a while to get there having to let off for EGT.

I have seen 99 mph in a 80 Rabbit 1.6D/4 speed with nothing more than a  timing change and 1/8 of a turn on the flow screw. It had more but I was making a spectacle of myself and it was a car I just sold to a customer. I did not want to have to buy it back.

it did not have a stock 1980 rabbit trans then. unless you messed with the governor, it didnt go 99mph with a stock '80 GC 4 speed. i could see it going over 100 with a 4A, or a GL or something like that. any of the 3+E transmixers will go that fast.

well, that was kinda a given. but still, in stock, un boosted form, i doubt the difference from a 1.5 to a 1.6 isnt going to be 17 mph..

cause my rabbit had a fairly healthy 1.5 in it, and it would only do 83. up hill, down hill, with a tail wind. only 83 mph. had to play with the government to get it to go any faster..

No, it was a bone stock 1980 N/A 1.6. The only mods were pump timing and some fraction of a turn on the flow screw. I did spend a fair amount of time doing the "Norwegian dyno tune". (Countless runs up the same hill with tiny incremental changes taking the best numbers and using those settings)

1980 would have been a 1.5..  The stock transmission was a GC 4 speed..  Final drive was 3.89:1 and 4th gear would be 0.91:1  with stock tires  (175-70-13 or 185-55-13) at 99mph the engine would be turning 5200 rpm..  :o    The stock governor won't allow it..

thats what im saying.. ive owned a grip of different 4 speeds, and diesels.. from stock, to built pretty decent..

99 mph takes HIGH gears if you dont have a governor mod..

with a GC.. my car turns ~5600 rpms (.97 4th gear) at 100 mph.. and its been discussed that 5600 is about when the pump rollers start skipping..

my car would NOT do 100 mph as a n/a until i modded the GOV.. it needs the extra fuel up top to pull to 100 mph..

plain and simple tho, if you had a stock 1.6, and a GC trans attached to it, and no governor mod, the only way to go faster than 83 mph is with another car/truck pushing you...

I'm always cruising around in 5th at 35-40mph (ACH) Getting onto the highway I'm usually shifting out of 4th around 60-65 though. I think the fastest I've gone in 4th is around 70mph. With no governor or tach I'm scared to take it much faster in 4th...

for a n/a, that sounds about right..

i could go 100 mph on a long straight stretch with my 4A and 1.6n/a..

now my car only goes about 115, but it gets there in a hurry. i got a GC box in here now, hate it. its like driving a 5 speed box with a blown up 5th gear.
