Sharkie's TSI Amarok Build

[Sharkie]

Was the Scirocco seriously down on Power?

I would have though a stage 2+ Roc would have been 200+kWaw given that it is running a K04.

I'd be interested to see the rest of the results to put the numbers into context.

Not many cars on the day to compare with I'm afraid, only 3 x 2.0Ts, Amarok, Scirrocco R and Mk6 GTI Stg 3 (275HP) And you're correct, I was expecting more from the Rocco as well. Don't believe the GTI owner was too happy either.

4 more FWDs ... Mk3s and a Mk1 Cabrio (none of which cracked 100HP) so the numbers had very little reference to each other.

The rest was aircooled much older VWs .....

[Sharkie]

Just as a reference, from testing during tuning, we already know that the Stg1 Amarok makes more power than a MK6 GTI Stg2 .....

Stg 2 on the Amarok to be an exhaust and possibly an intake, though the stock intake is pretty good and will be hard to beat. Some scope for improvement in the exhaust but not much, possibly ~5kw ....

The stock intercooler on the Amarok is massive with a different end tank design than any of the other 2.0Ts from VAG so we don't believe it will be possible to improve on it, even with Stg 3.

Stg 3 (K04) is expected so deliver good results (~+50kw) so look out for that in the future .....

That's a bit of a pity. What turbo was the Stg 3 GTI? I would have expected the Roc to be around that power level....

There's another dyo event being held with more watercooled cars: http://www.vwwatercooled.com/forums/...une-97704.html

I know they're looking for a couple more cars to make the numbers to run the event

Yeah, .... no. I don't have a lot of faith in rolling road dyno's. Have a number (sort of now), and will be sticking to the hub dyno from now on, where tyre pressures, wheel weights, strap down and cooling don't have an impact.

Considering the GTI will likely be running at that event again, I'll just take the figures and apply a correction factor to the Rok to see where it would have been on that dyno .....

Great result Sharkie!

Any idea when the tune's will be available?
Also interested in seeing what economy on cruise (if you can control your right foot now,lol) you get?
.
I have had a play around with the air intake behind the grill on mine and about to delete the centre muffler and had thoughts about cutting the cat out and replacing with a 100 or 200 cell high flow and get the cell rectified when the tune is available to us plebs.
.
Any ideas on what the difference is between the amarok tsi300 turbo and the golf gti turbo is?
.
Sorry many questions, but no one seems to be playing with the TSI300 amarok.

Don't worry, all the playing with the TSI300 Amarok (Or should I say TSI450 ) happens right here ....

Tune should be out in a few weeks time. Still doing some testing including road testing now, APR will release full figures and details when they are ready.

TSI300 Amarok's engine probably most closely related to Audi Q5 2.0T's with the turbo very similar but not exactly the same. Golf GTI and Amarok runs 2 different turbos and the Amarok runs a different exhaust cam to the GTI. K04 upgrade appears to be straight forward and easy to do and will be "tested" in due course .....

The Amarok's stock intake is very good (as in high flowing) and we have tested a few configs on that so far. Other than aesthetics, not much to be gained by changing unless you go beyond Stg2.

The exhaust due to the layout of the engine (longitudinal) is also pretty good, gains to be had though by going larger 3" v 2.5" and replacing the stock cat with a high flow cat. Due to anticipated low demand for this piece of hardware unlikely to be offered by any of the tuners, sho will have to be a custom job for those that want it done.

Also, fuel economy largely appears to be unaffected ..... did a 200km run yesterday (Brisbane => Sunny Coast => Brisbane with a bit of running around at the coast). Fuel economy at a fairly liberal interpretation of the speed limit still at 8.8l/100km overall.

In town using the extra power also seems to be consistent at ~12l/100km.

Do your wheels really weigh 40kg Sharkie? I look very fwd to catching up with you finally and doing some comparisons..

[brad]

Do your wheels really weigh 40kg Sharkie?..

It wouldn't surprise me. OEM 17x7.5 with road tyres on an Audi A4 will weigh in at 21-25kg depending on the style of the wheel. Every extra inch in diameter will add 1-2kg and every extra inch in width will add 1-2kg. Add in that they are "heavy duty" off road style rims & 40kg isn't outside the realms of possibility. All in the wrong spot too (outside of the cylinder).

If you can pull some weight out of the wheel tyre combo you'll see some noticeable gains in acceleration & suburban fuel economy.

[Guy_H]

My Stock Amarok 16"s were 32" kg's each (with tyres) on my Rok, I know have 18" ATS rims & 32.5" All Terrains, they weigh 39kg's a corner.

Load ratings are going to mean a certain mass with wheel / tyre that won't be easily overcome.

Doesn't worry me too much as I have a canopy, water tank, steel bullbar, winch, dual batteries etc etc....

Unsprung weight v sprung weight.

isn't the rule of thumb that 1kg of unsprung weight is equal to about 2.5kg of sprung weight? Plus the rotational inertia that has to be overcome.

I can see your point though. I once spent an afternoon swiss-cheesing & deburring the panels on a Cortina a mate raced. Possibly I pulled 1 or 2 kilos out of the panels. The driver was a BFF and weighed about 140kg. No amount of panel drilling was going to offset the tub of lard in the drivers seat.

So ...... we are well down the track of finalising the Stg 1 tune for the TSI Amarok .....

Bear in mind that this is really the last of the Gen 2 EA888s and in the Amarok with totally different hardware (stock FMIC, intake and exhaust all "better" and exhaust camshaft & turbo different) than any FWD engined EA888 VAG vehicle, closest comparison really a Q5 2.0TFSI.

Not releasing any official numbers as yet, but as a teaser .....

APR Stg 2 Mk6 GTI makes 174kw/380NM at the hubs on APR's hub dyno ..... what do you think the TSI Amarok makes ? ......

APR Stg 3 (K04) Tiguan makes 204kw/418NM at the hubs on APR's hub dyno ..... what do you think the TSI Amarok makes ? ......

How can we know?? you are the one should know it

Let me take a guess... mmm 151kw ?

More .....

Quite a bit more actually ......

Hint: kw somewhere between the 2 above, torque more than both .......
