Went up to Rocket Rally this afternoon with a B6S4, B5S4 and Supercharged Passat to do some dyno runs.

The previous k03 stage 1+ dyno results are here: http://forums.audiworld.com/a4gen2/msgs/935810.phtml

My setup for the dyno is as follows:

APR K04 91 octane beta file
Chevron 94 octane gas
TT225 386cc injectors
Jet Jockey turbo inlet pipe
Milltek exhaust
DSMIC

This is graphs of runs 2 and 3 and they are almost identical.

** Dotted lines are HP, solid lines are torque **

With my previous k03 stage 1+ setup I registered an average of 158whp.

Today with the 91 octane k04 file I registered 168whp so I would expect a few more whp when the release the 93 octane file for my ECU.

To figure out crank values a correction factor of 1.68 is required. How did we get that figure? At KTR a stock A4 1.8t registered 101whp on their dyno dynamics unit. So 170chp/101whp = 1.68 so 168whp = 283chp



Here are the runs 2 and 3 compared to run 3 when I had the k03 stage 1+ (red lines)

With the k03 setup the HP peaks out at 4750rpm and steadily falls until there isn't much left at 6000rpm

With the k04 setup you can see that the HP peaks later at 5200rpm and it does drop a little but the HP is solid and holds all the way until redline.

The amount of torque available after 4750rpm with the k04 is substantial compared to the k03 setup



But here is the printout I am sure everyone who is considering upgrading wants to see... k03 stage 1+ vs. k03 stage 1+ w/ upgraded IC vs k04

APR stage 1+ 93 octane - purple lines
APR stage 1+ 93 octane w/ upgraded intercooler - red lines
APR k04 91 octane beta file - blue lines

You can see the amount of power and torque gained with each modification.



Here is my k04 setup vs a PES supercharged V6 Passat



Here is the B6S4 w/ Labree exhaust vs B5S4 w/ GIAC stage 1

 

nice. i kind of expected a bit more tho

 

a 68% power loss through transmisson, something isnt right there. 21 is where it should be for AWD maby 25. its about 14% for FWD

 

Dyno Dynamic dynos are the lowest reading units so I didn't really give too much attention to the numbers.

I was more concerned with the graphs as I wanted to see how the k04 performed to the k03 setup.

 

does it feel much faster

 

It feels quite fast... but not as fast as your ride Jeff.

 

i was hoping that the dyno read low... if im spending the money on a k04 i want more then that...but that torque curve is very apealing

 

i have realized that dyno numbers dont mean crap. they all read different and dont really provide a deffinate number that means anything. the only numbers that really mean much are 1/4 mile times

 

As I stated above the dyno I am using is the LOWEST reading dyno that is used.

I am sure if I put my car on a Dynojet or Mustang unit I'd get much higher readings so that is why I stated I didn't give too much attention to the numbers and focused on the graphs.

If you map out the output recorded for the B6S4 and compare that to its crank values you will see just how much of a 'loss' the dynojet has.

 

Do you have the K04 turbo in there too, or just the K04 programming and a K03 turbo?

Where did you get K04 APR programming for the B5?
