VW TIMING COMPARISONS
VW TIMING COMPARISONS
=====================
Last update: Oct 21, 1994
The idea of this data base came from Peter Tong, however his original
data base got lost when he graduated.
This is also an amateurish way to finally measure performance changes,
and for me personally, a way to check whether something went wrong
with my cars over time.
How it works: Measure how long it takes to reach the following speeds
from a coasting start on a flat road in the following gears:
3rd: 40-60 mph
4th: 40-60 mph
3rd: 50-70 mph
4th: 50-70 mph
Repeat these test several times after you perform your upgrades on the same
road under similar conditions (same ambient temp, car warmed up, same
tire inflation, same gas tank level & same amount of junk in the trunk).
Obviously, the higher speeds must be performed where it is legal to do
so, and out of the way of general traffic ;->
I have found that there is about a 10% error in these measurements.
I have also collected other data.
As Peter explains below, these tests are "healthier" than a 0-60 mph
spurt as it stresses your car components less.
Furthermore, 0-60 times also depend on the quality of your tires, driver
skill and other factors, while the above don't and are therefore more
repeatable.

I pretty much just find myself as flat a freeway stretch as possible, then
try to get onto it between the "waves" of cars that come so that I have room.
I get into the gear I want to test, pull out my trusty casio, flick it to
stopwatch, get up to the speed I want to test from (40 or 50) and while
holding that speed absolutely punch the gas while at the same instant hitting
my stopwatch, then the moment the car goes through the target mph I hit the
watch and then let off. I usually do runs in both directions just to make sure
the times are accurate (depends on the flatness factor). This is pretty
much how I measured progress on my previous car an '83 GTI and how I currently
test my 82. I used to do 0-60 but found traction problems usually skewed the
times depending on the quality of the launch. This is not to mention the
stress a "drop the clutch" launch does to the downpipe studs - esp if you
don't have the techtonics front mount - and to the CV joints, (the whole
drive train). On my 83 GTI I usually did 40-60 in 4th (6.8 stock, and 5.5
with std tricks) and occasionally 30-50 in 3rd. On the 82 I do 40-60 in
3rd and 50-70 in 4th. I got the 50-70 in 4th from reading David Kennedy's
response to Neil Martin's critical letter concerning the Lurching towards
Success II article in VW & Porsche - there Kennedy quotes a time of 7.2
seconds from 50-70 in 5th (.91) which in my car is the same thing in 4th
since my 4th is .91. Since I modeled my car after his, I can see I have
a ways to go. Our cars are pretty much the same except that this guy has
a ported and polished head and Schrick 280 last time I heard. My
convertible (thanks to the 80 kg top) weighs in at 250 lbs more than his
lightweight 84 GTI though. Recently I heard from Mecca Coolant company that
he was using their Mecca Coolant along with an Oettinger modified
head gasket to run his 84 GTI with 11.5:1 or some higher than normal
compression ratio. Supposedly he is writing an article about it that should
come out soon in EC.
Regarding your car being "stock", stock for you means modified for me, since
most all the mods I've done have just brought my car's engine up to your 1990
"stock" level. In fact, your 2.0 16V in stock trim may put out slightly
more hp than my 2.0 8V (134>130). I liked the rpm range for the 40-60
test in 3rd because it tests from 3000 to 4500 rpm on even the wide
ratio trannies. I think this is a balance between high rpm power (highway) and
low end grunt (for in-town throttle response). Oh well, just my $.02 hope it
answered your question.

Jan, your SLC should do around 3.7-3.9 seconds or so - based on 2 other
SLC owner's figures (sample =2 isn't that reliable but still). Those
are in 3rd gear also = 1.30 ratio. Not sure if the timing is even
adjustable on those cars due to the motronic - On the Audi 80s it isn't
hardly adjustable at all. I'd just make sure that whatever the computer
uses to measure the vacuum (load) is feeding the correct signal to the
black box. I also test both ways to average out the times....

Finally got to install the first of my goodies for the 90 G60. THE
NEUSPEED P-CHIP.
Here is a summary, more will follow:
Installing:
1) Hardest part was undoing the philips screws inside the ECU box. Had to
use lots of force and I was scared to break something. I managed to do it
ok. The Neuspeed instructions were adequate.
Impression:
1) I liked the incresed rev limit. I used to hit the limiter a lot, now I
don't. I found it too low before and I now have the extra little bit that
was needed to make it smooth around the corner.
2) YOu can feel that there is less lag below 2000 rpm. It feels more
responsive. Top end seems the same. Most difference is seen in first gear
only.
Hard Data:
Problems: In my area it is rally hard to find a straight and flat piece
of road without the traffic. So there is some errors with this data.
Note: I used the rpm to measure since you can repeat it better. The rpm
has a more percise scale and the speed is not messed up with different
tires so it can easily be dome by others. Also 60 miles is about 103 km/h.
Car: 90 G60
mods: K&N air filter
Tires: 195/50/15 Sport Contacts (Conti)
milage: 56K Km
gas: 1/2 tank
temp: 22 deg C, sunny, ~5 knots of wind
oil temp:108 deg C (forgot to see when chip installed)
test before chip with chip
---- ----------- ---------
2nd 4000-6000 3.07 ?
3rd 1500-5000 11.99 11.87
4th 2000-4000 11.75 ?
5th 2000-3500 12.71 15.87 (diff road)
0-100km best 9.03 best 8.37
More test to come.
BTW, 2nd 4000rpm is 60km/h
2nd 6000 is 85
3rd 1500 is 35
3rd 5000 is 110
4th 2000 is 60
4th 4000 is ?
5th 2000 is 75
5th 3500 is 120

Hiya, all, a few of us from the list got together this Sunday morning to
do some timing runs on a casual basis, and I thought I'd pass on our results
to you folks. We made one run each in our respective cars (my first pass got
horrendously slow results, too embarrassing to publish here!), then decided
that Jeremy, the owner of the Passat, would do one more run in each car. All
measurements were made on a calibrated Vericom VC-2000 performance computer
kindly loaned to me by ND.
These results are more meaningful as a rough indication of the relative
performance of these 3 cars rather than what is really achievable. We only
timed 2 runs per car, did not thrash the tranny at all from dumping the
clutch at redline, and this was our very first experience at doing this sort
of thing! Also we didn't try to shave off weight by discarding the rear
seats or spare tyre, in fact some of the cars were fully loaded with stereos,
sway bars, strut bars, stuff inside and also in the boot, uh, trunk. To top
it off, there was a fairly strong cross-wind that day, and we showed up
outside the ND premises in the morning all bleary-eye and hung-over from our
wild excesses the night before...
* Corrado A *: Kevin Peterson, Metallic Green 93 Corrado VR6, stock VR6
except for drilled airbox, TSW EVO 17x7.5 w/Dunlop D40 M2 215-45-17, Eibach
Stress Bar, Koni adjustables w/Neuspeed Race Springs, European headlights.
* Passat *: Jeremy Mitchell, Colour-coded Black 93 Passat GLX (as featured
in the EC article titled "Black Light", summer of 1994), drilled airbox with
K/N Filter, Neuspeed Throttle Body, custom AMS chip (only two chips like it,
the other one
is up in Canada in a race Corrado), MoMo Ferrari 17x7.5 w/Yokohama
AVS215-40-17, custom Borla Stainless Steel Exhaust courtesy of ND, all the
Neuspeed suspension mods, custom Neuspeed springs (shorter springs than the
normal Neuspeed ones), Koni adjustables, Zender side skirts, tinted
tailights, tinted projector beam headlights, 180 degree fan
switch/temperature gauge. This car is usually equipped with nitrous but the
owner ran out of NOS that day so we were unable to measure the difference
from being on the bottle - a pity...
* Corrado B *: Edward Thai, Black 92 Corrado VR6, Neuspeed Throttle Body &
P-Chip, K&N filter element in factory airbox, ForgeLine 16x8 w/Dunlop SP8000
225-40-16, Neuspeed Stress Bar & Anti-roll bars, ABT springs w/Bilstein
Sports shocks.
Location: Somewhere in San Jose
Traffic: Light
Time: 11:30am - 12:30pm
Weather: Mid-70s, dry & sunny but windy
Corrado A Passat Corrado B
0-60 mph (seconds) 7.67 7.46 7.08
0-30 mph (seconds) 3.11 2.89 2.76
1/4 mile time
(seconds @ mph) 16.12@91.9 15.86@91.3 15.60@93.8

15 ft 1.44@14.2 1.50@15.1 1.43@14.9
With much more practice/experience and excercising less caution/restraint
about beating up on our cars, we reckon we could probably have shaved off up
to an additional 0.4 or 0.5 seconds off our 0-60 times... Anyway, I want to
thank Kevin & Jeremy for helping me out with this exercise, we had fun
comparing notes and following each other at some speed round the entry & exit
ramps to the Californian freeways... would like to do this again sometime
soon with MORE participants! Anyone interested?
Cheers,
Edward
P.S. Did one quick braking run (not going all-out on the brake pedal or
really warming up the brakes) on my Corrado which is equipped with stock
rotors & calipers but with the addition of Repco MetalMasters pads &
Stainless-steel lines: 116 ft from 56-0mph [I believe R&T got a best
braking distance of 154 ft from 60-0 mph on a stock Corrado]

Well, I don't have all the data but here are some random numbers you
might be interested in.
90 G60 with K&N filter, 2 people in car, dry, less than 1/2 tank of gas,
worn down 195/50/15 Sport Contacts.
Applies for all numbers. Pulley = pulley + chip
Gear RPM Speed Stock Neuspeed Chip Pulley
5 2-3.5K 75-120Km 12.71
4 2-4K 60km- 11.75sec
3 1.5-5K 35-110 11.99 11.87
2 4K-6K 60-85 3.07sec
2 2-5K 3.2
0-100km/h
stock chip pulley
~9.5 ~8.7 ~8.1
I'll eventually get the rest of those figures, someday.

The dealer finally admited that my C needs a new lifter. The one that
makes all that noise when starting the car is starting to speak up when
warm. Soooo.. the car gets a whole set. Which is good, because it will be
a cold day in you know where before I'll drop a set of thousand dollar
cams onto shit lifters.
I did a few acceleration times today. I would have liked to do more, but
traffic and wet roads prevented alot. I did three runs for each, and then
had my friend do several also. The car has ported t-body, APS chip,
gutted airbox w/ K&N, match ported intake manifold.
2nd gear 40 - 60 average 3.26
3rd gear 40 - 60 average 4.43
4th gear 40 - 60 average 6.19
4th gear 60 - 80 average 6.37
hopfully the cams will show some improvment.

I picked up my car today. I did the same timed runs.
before after
40 - 60 2nd 3.26 2.99
40 - 60 3rd 4.43 4.01
40 - 60 4th 6.19 5.94
60 - 80 4th 6.37 6.06
Do I think the Schrick 260 cams are worth the $760 I paid. No, not
really. The car feels faster and it definetly pulls to redline much more
quikly, but I feel they simply were not worth the money. Of corse I may
change my mind after driving a stock C, that may be what it will take to
realize the gains. We'll see....

Well I'm glad somone appreciates it (actually your the one who got me to
do it in the first place)! I've just been out driving for about 45
minutes, and I think I may be a smidge hard on the cams. Techtonics says
10hp peak gain. I guess that's about what I'm getting. I mean what do I
expect from 10hp? a full second off of my 0 - 60 times. Unlikely. Lots of
work and power are needed to get gains like that. I would feel like I
took it if I had paid over a grand though.
The car also has K&N filter w/ both snorkels removed from the airbox,
P-chip, ported t-body (I should take a picture so you can see that alot
can be ported), matchported intake, and cams (260). I plan on cutting and
welding the drivers side of the manifold for improved high end flow. Some
day I'll dyno it (if I can find one).
I'll post about everyone I talked to about which cams (260or 268) wre
better, and wether or not it was an opinion or supposedly backed up by
dyno tests etc. later. It's time to eat.

Was chatting with Stu, owner of the EIP-modified 3.1L VR6 Golf
(A2), and learnt that he had just recorded the following 1/4-mile
times in 3 runs around 1pm this Sunday, 22nd Sept. 1996:
13.4 sec @ 105mph
13.5 sec @ 107 mph
13.6 sec @ 102 mph
These are verifiable measurements taken at an official drag
strip/track, and Stuart also has a video of the event. Weather was
extremely humid (rained that afternoon) with temps in the 63 F range.
A problematical 2nd gear prevented Stu from improving on the above
times, but he was quite pleased with his results especially
considering this 3.1 GTi is a streetable daily driver and completely
naturally-aspirated - NO turbo, supercharger or NOS trickery employed
(but a turbo future is planned...)
For reference, Steve's 3.0 C. (also EIP modified) last recorded a
13.57 sec 1/4-mile with an exit speed of 104.1mph with some extra
help, and the EIP 2.8 Turbo Corrado prototype recorded similar figures
in its dragstrip debut running on 8-10 psi...
Having not frequented any of the Battle of the Imports or Shoot-Out
events, I was just wondering what souped-up VR6s have achieved thus
far in verifiable runs?

I too read the article in EC mentioning the g-tech. I decided
what the hell, let me get one. It's pretty much what it says it is.
The only calibration you have to do is adjust the mounting bracket
(just like a radar detector's) so that the unit is perfectly level.
If you don't, it'll measure the earth's gravitational pull, and refuse
to take any measurements.
Horsepower measurements require the car's weight, and must be entered
each time you turn the unit on (if you intend to measure hp).
Other than that, punch the button, wait until it says '' and
accelerate. It'll sense when you start and when you hit 60, then
it will either start to time the 1/4 mile or the 60-0 braking distance.
You don't have to start braking exactly from 60 because it'll know when
you were going 60.
You have to turn the unit 90 degrees to measure cornering forces.
I haven't had the chance to try this yet.
Another post mentioned something about adjusting the sensitivity- this
one has no such adjustment. Must be a newer model. They do
offer a 30 day money back guarantee, so it can't hurt to try it.
I ordered mine through their web-site on a wednesday and got the device
on friday by priority mail. I paid $139 plus shipping (but no tax)
Their web site is www.gtechpro.com.
I don't work for them or have anything to gain by giving you this info.
Just for grins, here are some numbers I have obtained:
0-60:
6.82 Sec. \ without shifting into third
6.84 Sec. /
7.4? shifting into third
7.5? shifting into third
Wheelspin in 1st really makes or breaks this one.
60-0 (only one measurement so far, with ABS)
127 feet
1/4 mile (only one measurement)
15.5? sec at 92.? mph
Horsepower is waiting on the real weight of my C. I know someone posted
this a while back, but... could someone post that again? The door
jamb and manual don't have enough information to get it right.
Oh, all these numbers are for a '90 G60 with Autothority stage III,
ISV bypass, stock exhaust with melted cat and bad oxy sensor, stock
size tires-Pirelli P700Z's.
Ambient temperature was mid to high 60's, Houston humidity (90% +).
I'll post some more numbers when I get a chance to try it again.
It is hard to find a place to do 1/4 mile runs.
You'll also get a chance to see the difference temperature makes when
we get back up into the 90's.

Well, Nick came again today, we took a ride to a street close from here
and we tested our braking and acceleration performances.
1st, here's our cars :
Nick : 94 VR6, 205/50/15 stock rims Yoko AVS almost new, P-chip, P-flow,
no short shift kit, stock pads, discs and calipers, stock suspension.
Frank : 93 VR6, 215/40/17 Toyo T1 almost new, TSW Stealth 17x7.5 6
pounds heavier than stock wheels and 0.5-0.7" taller, P-chip, custom air
box, grinded T-body, custom short shift kit, carbon pads CC's blue
compound, stock calipers and Euro/Brembo new discs, NS Race springs and
Bilstein sport shocks.
We were BOTH sitting in the car, one was timing, the other was driving.
So the times are too HIGH, cuz we were both in the car.
Braking times :
>From 70km/h to 0km/h in 3rd gear. (43.5mph to 0)
Frank : My time when the pads where enough hot, was about 1.6, just did
few stops, not a bunch. ABS didn't worked a lot, just a little and wheel
blocking was almost imperceptible. My other time was 1.87sec. I bet I
could do better, but didn't wanted to do more.
Nick: His braking time was ABOUT 2.1-2.2sec, cuz I screwed up the last
stop, I pushed on the buttom too late. His other stop was 2.74sec.
ABS did work quite a lot, and there was some "long" wheel blockings,
sometimes, before the ABS stopped them. He could also do better, if he
could prevent the wheels from blocking, which seems to be quite hard.
Acceleration times :
>From a 0km/h to 80km/h in 2nd gear. (0 to 49.7mph)
Nick : 6.44sec did about 3-4 tests. The other one I remember is 6.74sec.
Frank : 6.7sec, did only 2 tests (I remember now Nick, I only did 2.)
and the other one was 6.99sec, with a VERY BULLSHIT start, like the
second one, but that one was a bit better, though still bullshit. We
did not swap cars, that's another test we should do another time.
We both had (and still have) some probs with the starts. We could do the
0-80km/h in about 5.7-6.0sec if we could do better starts.
Our times seems to be about the same, though I'm sure I have 0.2-0.4sec
less than him on a run up to 100km/h (62mph).
L8r!

As a follow up to your article, "VW Timing Comparisons" here are some
measurements I did before on my Scirocco 16v.
Induction: Stock induction, with K&N
Injection: Stock injection
Head: Stock 16v head, cams, etc.
Block: Stock 1.8 16v.
Ignition: Stock knock sensor ignition, Bosch Platinum single electrode, Beru
wires.
Exhaust: Tri-Y racing header, 89 Jetta Cat, stock tubes, Cherry Bomb muffler,
3.5" Tip.
Transmission: Stock Scirocco 16v tranny (3.45/2.12/1.44/1.13/0.91//3.67)
Suspension: Suspension Techniques lowering springs, Boge Pro Gas shocks on 4
corners with Falken V-Rated 195/50-15 tires on Sendel 15" Aluminum rims;
otherwise as stock.
Estimated HP: 135hp+
Acceleration times comparing car before all mods (completely stock) and after
all mods:
Stock Modified
0-60mph: 8.8sec. 8.2 sec.
0-100mph: 26.4sec. 22.3sec.
1/4mile: 16.6sec.@83.6mph 16.1sec.@86.1mph
30-50mph:
2nd gear: 2.9sec. 2.8sec.
3rd gear: 4.5sec. 4.3sec.
4th gear: 6.2sec. 6.1sec.
5th gear: 8.7sec. 8.5sec.
50-70mph:
2nd gear: (too high rpm)
3rd gear: 4.7sec. 4.4sec.
4th gear: 6.2sec. 6.0sec.
5th gear: 8.7sec. 8.3sec.
Also:
Top speed (6250rpm):
120mph 127mph
Fuel mileage:
City: 24.1mpg 24.2mpg
Highway: 33.8mpg 34.1mpg
Lateral Acceleration:
0.80g 0.86g
As you can see all times got better while I also got better miles per gallon
with the better breathing filter and exhaust.
I want to increase my car's performance by adding more bolt-ons. Is the
European intake camshaft the next step? Is it legal (emmisions)? How about
the Techtonics Power Module? I'm suer to put a Techtonics exhaust whithin the
next year, so that's a given. How much ummph should I gain by adding these
three above? Also is it worth (in terms of HP) to polish the throttle body
and intake manifold? I heard one shouldn't port the intake manifold becuse VW
reduced its diameter from the 1.8 16v prototype to gain extra power at lower
rpms (That's where I need more!!!). What other improvements are suggested for
the engine?
Thanks a lot for your time,
