Brisbane Polo Dyno Day Results - 25 August 2012

[vwthunder]

Eddy's K04 Polo, still the king, has all bolt on performance parts that can be fitted in a single day. No engine performance tuning has been done in over 4 years.

Well done Eddy

Not for long lol

Hope that's clear enough.




Just to give it a bit more perspective, the maximum difference between Jason and your requested boost is .6 psi.

Legend! Cheers mate

Wow, way to run a comprehensive Dyno and data collection guys, world class stuff. A template for future dyno comparisons!!

What was with the MK4 GTI Stg3 making a low 153.554kw, but a huge torque number 396.328

Maybe that's a reflection of the small port 1.8t v's the large port?

Bigger turbo with less power but more torque

Lito, has a Frankenturbo with CC. AFR (Air fuel ratio) was dangerously low. Tried 3 runs each aborted when AFR went to 1.2 ... 1.3. Finally decided to risk it and do a run that was also aborted at 4500rmin. Guy and James was not willing to have the engine self-destruct in their workshop .....

So it made 153kw at 4500rmin with no idea as to what it would make if allowed to run out to 6500rmin. It was a clear indication of (a lot) more tuning needed .... .... Good torque though.

Lito can post the graphs up if he wishes. Extra graphs showing the AFR was done for him.

Also now the reason I will not go Frankenturbo ....

For those that want to know what the AFR is about see this graph:

All t

All the data above are showing Lambda figures ....

I am keeping quiet, until this has been investigated. Not what I have in logs with the wideband from during the tuning, as I wouldn't want melted pistons on my conscience either. To be honest it was running rich then if anything.
