Polo Dyno Day Brisbane, Saturday August 25th

[vwthunder]

Is it one of those Hub Dynos

Not having a go at you, but i think they read higher as you dont have the wheels, rotational mass etc

Someone tell me if i am correct or not

Not to rain on your parade

[s4mmie]

Yep, hub dyno.
Pretty sure there's about a 10kw difference.
I ran 136 kw and 305 Nm of torque, so 126 sounds about right.

lol yeah man, i was just sh*t stirring you leaving that out

but to be fair its more consistent as we dont have differences in tyre pressure etc to deal with

Im guessing it is like running 12 inch wheels lol. At the RTR dyno day the operator was telling us that some guys running semi slicks were loosing power as even the tires make a difference

[jasn78]

yeah guy was saying the same thing so like i have always said re dynos u cannot compare different ones thats y the qtr mile is a better comparison

Quarter mile time is the driver lol
Yes and i will admit, your good at that

Anyway back on topic

So... hows it going lads?

Keen to see some data.

[Sharkie]

OK, the official results from the day!

Huge thank you to Guy and James for running an excellent day and putting 17 cars on the dyno! And thanks to Eddy for cooking the snags!

Please note that the results are all uncorrected at the hub figures. These are not flywheel figures. This was not a wheel dyno either so no excuses for strapdown procedures or wheelpressures ..... All runs were conducted in 4th gear.

For information on the Dynapack chassis dyno please see here: Dynapack Arguably the most accurate dyno setup in Brisbane at the moment.

Mods (main components only) indicated here as follows:
Stock = well stock .....
Stg1 = ECU only
Stg1+ = ECU + intake
Stg2- = ECU + intake + exhaust or Intercooler upgrade
Stg2 = ECU + intake + exhaust + Intercooler upgrade
Stg2+ = ECU + intake + exhaust + Intercooler upgrade + Fuelling etc
Stg3 = ECU + intake + exhaust + Intercooler upgrade + turbo upgrade

There will be a full spec list of the GTI Polo's that ran a bit later today.

In order of running:

Well done all !

Nice. Some strong figures there. Not much to decipher at this time other than to see some strong torque from the K03s with good supporting mods and CC.

Anyone take any photos?

[Redliner]

Great numbers there guys. It would be good to do this in Sydney.
Can we conclude anything about the types of intercoolers with this info. Isn't that how all this started? Could be useful for those who are going to purchase one. Hopefully the Seat core performed well as I've got one on order.

<EDIT> Needless clutter

[noone]

More detail to come Redliner...

Not sure how worthy adding dyno's from other days will be, it's not an exact science and most results will be ATW.

Personally, the logs and torque curves will be what influences my future purchases (eg cooling, exhaust, tune or just some better rubber)

Hey mate, from a thermal aspect only I think the
list went like this from best to worst;
Forge
Seat
Apr
EBay Apr style. Sorry can't remember whether Jason's or Sharkies were better.
Stock side mount.

Interesting though was the Forge and Seat were the only two that didn't suffer from heatsoak.

Interesting info. Alot of forum posts were critising the Forge yet performed amongst the best.
Which Forge intercooler was it?
