Quarter Mile - APR Stage 1 vs Stock

[krracing]

I know a lot of you have been waiting for Sharkie to use his G-tech for some acceleration figures!

I took my Tig down to Kwinana Motorplex this evening for a back to back test, with and without APR Stage 1 (98RON) - everything else on the car is standard.

Here are the results:
Firstly - weight - withOUT me, it weighed in at 1560kg, less than 1/4 tank fuel.

WITHOUT APR
15.775 @ 84.66mph, 136.24kph

60' 2.158
330' 6.399
660' 9.985 @ 110.70kph
1000' 13.108

Ambient Temp - 19.2
Density Altitude - 170m (lower the better)
Wind - 12knots 45degrees on nose (headwind)

APR Stage 1 - 98RON
14.503 @ 92.78mph, 149.31kph

60' 2.066
330' 5.957
660' 9.224 @ 121.90kph
1000' 12.072

Ambient Temp - 19.3
Density Altitude - 174.3m
Wind - 15knots 45degs on nose (headwind)

I was quite pleasantly surprised with the result!
Bang for bucks, it is the most beneficial thing you can do to your car I've decided - some people spend $1000's on an exhaust (or equivalent) to see MAYBE 0.2secs gained in 1/4mile time, but this was over 1.2secs gained......

Considering further upgrades, but all in due course.

Would still love to see Sharkie post some 0 - 100kph times!

Cheers,

KR

Sorry, for the record I drive a '10 manual 125TSI

The figures on the R/H side look a bit 'scewed', no?

I'm sorry but I can't see logic in spending $2000 to gain 1 second.

Careful there Mickofoz - a comment like that could cause a flame war. It's a question of horses for courses. Some people derive a lot of pleasure from tinkering with their vehicles and squeezing more power out of their engines. Some people like lowering their cars, while others like increasing their clearance.

The Tig is proving to be a modders dream it seems, as the engines are quite substantially under-tuned with large margins for safety. Posting times like this just gives a real world representation of the difference the remap makes. You have to consider how much of a difference that second makes in everyday driving when pulling away from the lights, overtaking, nipping across intersections etc. 1 second is pretty substantial. If you had to see the differences in distance traveled at the exact same time intervals, you'd see the remapped Tig would be quite far ahead of the stock one.

Awesome work mate!
All that with a head wind too.

Just proves that an ecu remap is the best mod you can do to your euro car.

Thats just because you don't understand what it takes to improve a quarter mile time by 1 s .....

In reality that is the equivalent of more than 10 car lenghts (40+meters) between the 14.5s car and 15.7s car ......

Well done KR .... and that with a still tight Tig ! - Are the tyres still stock?

Should be doing some testing this weekend ..... provided the rain that showed up last night clears soon .....

I believe there is an easy sub 14s in a Tig .....

Hi Sharkie - Yes, that was with stock Hankook tyres - to be honest, i don't think "semi-slicks" would make any difference at all... Being a part-time 4wd, you're never going to get wheel spin anyway off the launch (on a racetrack is a different story...).
Both launches were at about 6k rpm and the thing just squatted and took off! If anything, I'd consider going up in tyre pressure to get closer to wheelspin but lower the rolling resistance for a higher terminal velocity.

Without a cold air intake it seems to run out of puff high in the rev range, so I found myself short shifting - leaving out the last 1000rpm.

I'm pleased I took it down, and even more pleased with the result/chip.

You're absolutely correct about real world applications.
To put it in perspective:
over that short distance (400m), the chipped car finishes some 50m ahead of the unchipped car. 400/350 = ~14% more distance covered.

On the street, the car is more driveable, more user-friendly and on top of all that, it's a SAFER car!

The figures on the R/H side look a bit 'scewed', no?

haha - sorry about that - i 'blurred' it to avoid any confusion that I'd actually run a 13.078 quarter!!

Awesome work mate!
All that with a head wind too.

It was a significant headwind - an earlier run didn't have as strong a headwind, not quite as good "barometric" conditions and an average launch, but still achieved a higher finish speed - only 1km/h but it was really consistent throughout the night...

15knots = 27.8km/h (@45degs) => 19.6km/h headwind.
trying to push just under 3 square metres of frontal area into an additional 20km/h adds up!

I've been able to get mine to wheelspin a bit ....

and the Carbonio has shown on the Dyno (on my car) to keep power levels steady between 5500 & 6500 rpm with no drop-off. In fact I reach peak power at 5500 and keep it at that level to beyond 6500.

The rear silencer tests from yesterday added more power yet again and still no drop-off.

EDIT: and to put it into perspective some more .... local R36's have been battling to get 14.4s quarters and thats a $65K+ "performance" VW .... I believe a lightly worked Tig will have a R36 .... .... but then the latest Motor magazine had very dissappointing R36 test results ....

I'm just wondering what the R20 (coming in at nearly 300kg lighter than the Tig) is going to be like

Fantastic post too KR!

[krracing]

No worries mate

How is the R20 300kg lighter than the standard Tig??
Where on earth do they find 300kg! insane..
are there any links to info on the R20, photos? That thing's goin' to be an absolute weapon

exciting...

I thought an R36 was a mid 13sec quarter mile car? Is there something different about the locally delivered ones?

with a decent launch most mkv GTIs will do a low 14. So whilst a mid 14 is respectable time for a soft roader its not going to be eating every second car on the road. The trap speed seems a bit low too. Most GTIs tend to get up in the high 90s dont they?

I thought the same Tim - RE - trap speed, it just seemed to taper off at the end!

1. There was a significant headwind, 20km/h right on the nose, but not enough to cause a HUGE loss in speed

2. It's a bigger vehicle dimensionally, larger surface areas, more difficult to punch a hole in the air at higher speeds

3. As above, larger vehicle by weight @ 1600kg

4. 4motion - despite a good 20' time to kick things off, there are probably more drivetrain losses than a full-time Front Wheel Drive car, even if it's running mostly Front Wheel Drive bias.

Any other thoughts as to why it was down on trap speed??!

I had a look at http://www.dragtimes.com/ and my consensus was::

the equivalent (stage 1 APR tune) mkV Golf is about 0.6secs quicker down the strip than the Tig.

It's difficult to say; some have DSG and some don't - is DSG quicker?..

At the end of the day, the Tig IS a "soft-roader", and there's really nothing in it's class that can compete in these circumstances; to my knowledge..

I'd pay good money to see a GTi out on the dunes and survive to tell the tale!!

[Tim]

dsg will be a bit quicker yes. Unless the driver is a gun with very little mechanical sympathy!

Sorry I wasnt trying to bag your performance. As mentioned its respectable!
I didnt think about the aerodynamics. That could possibly explain the nice time with low trap speed I guess.

[krracing]

Did a quick search - i'm guessing the R20 is not a Tiguan but a Golf?

or am i way off!?

Are there plans for an "R" version of the Tig?
