Max K03 Tune

[break]

Is it just me, or are the numbers pulled in Aus lower or the dyno's reading lower? Always seems like stock numbers are a little lower here... Could just be my poor kw-hp conversion in my mind.

We can't compare our tunes to the euro tuners most of the time.

They are happy to push the limits a little more on the knowledge that the climate will always be cooler and heat related issues won't be as big of a problem. Look at the drag racing scene, for a long time most of the 4cylinder/rotary records were held by South American tuners simply because the location of the tracks in relation to the elevation, climate, and the number of trees in the area supplying oxygen.

At 20psi on our K03s we are already way up the end of the efficiency range of our turbos, it very quickly gets to a point where there is simply no benefit to add any more boost due to the extra heat being added negating the addition of the boost in the first place.

Either way, my opinion is still that if you're looking to spend the cash for a max K03s tune, then it would yield better results for similar cash by opting to go for a bigger turbo instead.

Differences in fuel between here and Europe will make a bit of a difference as well ... 98 RON maximum is rubbish

Most of Europe only have 97/98 octane... with only a select few places at 100/102 ron.

Either way, if you want big power from a turbo you're better off with E85 (so long as you have the fuel delivery systems to accomodate the extra ~30% flow rate needed)

With E85 (any Ethanol fuel blend imo) you are opening a can of worms and I can't see it being worth it. Also, E85 is only about 94 Octane, so it isn't the greatest fuel for performance, so I can see why you'd need to pump more in to get power.

100 RON or higher here would make me happy.

the reason HP figures are lower in australia might have somting to do with the heat.
it's a warm country and a stock IC can hold power long.
so you guys probably have heatsoak right away.
and it's a common fact that when it's hot, Hp will be lower then when it's colder.
also sea-level has invluence on HP-output.

about the reliability, it's nice to have 10 - 20Hp more then you have now.
is it worth it?
i think so...
it all comes to how you drive the car also.
if you go to the red zone and rev limiter, shift like a maniac and use the power every single day, you should not go to the max. capacity of the turbo.
you will only end up destroying it.
if you drive it with a bit of common sence, it should be allright.
allways drive easy when the engine is cold.
install a oil temp gauge to know when the oil is at temp. (important)
if you do this it's hard to break the turbo or engine.
but it's normal for when you ask more from the turbo, you will ask more from his reliability.
life span is in your own hands most of the time

but if the turbo comes to an end, it's a good time to go for a K04-001 :p

I think you'll find a LOT of turbo/import people in the drag scene use E85 for its performance qualities (once you tune the car for the fuel).

Hell, have a look at the video HPF did to test various fuel types: Episode 10 Now Online – The Fuel Test | OzGarage

Octane isn't everything, the temperature and speed of the burn are more important... and this is where E85 blitzes normal fuels, particularly in the burn temperature stakes.

It's much the same reason methanol is used in racing... it's not because of the octane, its purely because of the burn temperature.

The whp figures used on AUS dyno's (Mainline / Dyno Dynamics) always read lower than US based dyno's (dynojet & Mustang) - Dynapack ones read pretty much the same around the world - as long as you look at uncorrected data, not SAE or DIN corrected data.

Maha & Bosch dyno's read similar to Mainline when using SAE corrected wheel number, but the crank correction is Waaaaay different!

Maybe noone should re name the thrread "How much power can a K03 make for a very short time" - or "Hand grenade tune!"

Made me think of this one.

Nice!

Whilst I'm not interested in running stupid boost, I do find it interesting how the different tunes get their power. I think its fair to say that I don't know enough to be able to compare tunes other than with my butt-feel, but I think there is quite a difference between how the power is mapped.

I'm seeing some tunes hit psi's in the early 20's whilst the APR seems to top out at about 17 (no spiking logged with Vag-com).

I'm pretty confident with the FMIC and other mods I've done that the setup should be able to handle more than 17psi reliably... Just have to decide on which of the paths I'm going down (Garret or retune).
