RK Motion 1.8T dyno results - ibiza

Postby georgie » Mon Dec 14, 2015 9:56 am

179kw 380nm from a k03s 1.8T, damn that is impressive!

Who's car is this and what mods? I see the sheet states RK Intake only.

Is that dyno reading at flywheel or at the wheels?

Why does the Torque peak so late?
That's uncharacteristic of a K03s

Looks like stealth in durbs. Number look right for that dyno

Big boost spike if they making peak power at 4500 rpm.

Well played sir.
We all know the limits of the 1.8T on stock rods and small framed turbos.
Torque and power curves are moved higher up in the rev range, also notice how power is held almost until redline.

A later peak torque also helps with getting the car off the line. I mean who wants a dyno queen

Good work Wez, most guys have long forgotten the 1.8t maps, so its epic seeing you and RK are still developing them, personally I think you guys have been thinking out the box by moving torque higher up the rpm, and the results speak for them self. :hurray: :hurray: :hurray: :hurray:

True (maximum) torque peak would be determined by the turbo geometry and engine characteristics. To move the peak later would be to lop the true peak and accept a lower torque peak. So 380-400 Nm true peak at 3000-3800 rpm, and 350-360 lopped peak at 4000 - 4500 rpm. You can't move the actual torque curve without changing mechanical components (turbo/cam/headwork etc).

Great figures though, nice and smooth!

All good and works in theory.
Anyone is more than welcome to come and see the car and inspect the 100% stock factory components mentioned above.

Do you know that peak boost has an effect on torque levels? A boost spike will give you a sharp rise and the peak hold boost will give you the plateau. Upping the boost from the normal 1.3 spike and 0.9/1 bar hold will change the characteristics a lot

I think you misinterpreted my post, I'm not contesting whether the car is stock, just saying that the torque curve has been manipulated by reducing the peak to below the true peak attainable by the turbo.

Please accept this humble paint diagram I made to illustrate:

The setup is exactly the same, but in the red graph, the boost has been reduced, showing a lower peak and a later peak, although the peak attainable torque curve itself is the same.

(was trying to answer queries in the thread, not contest your engine :hug: )

I understand where you are coming from. Let's say the 380 is being made on 1.3 bar spike settling to 1 bar then dying to 0.9 bar and timing advance is quiet generous in the lower RPM. Then let's say a 1.6 bar spike is then added into the mix with a little less timing advance, the turbo works beyond its optimal range for those slight few 100 rpm then settles back down to 1.2/3 bar and runs all the way through to red line. This will definitely have an effect on the torque curve and the way the power is applied.

Fully agree, in the above illustration the black line can be considered to be the ultimate torque curve, the curve where boost and timing are perfectly balanced to provide an optimal torque situation at each point in the rev range. The spike you mentioned would then push the red line up to the black line at the highest point giving the spike that small turbos are known for. But a good tuner would know not to push torque at the true peak and rather allow the WG to bleed off exhaust gas and boost to save rods.

So changing boost/timing would definitely change the effective torque curve, but the ultimate torque curve attainable would be a function of the turbo geometry and mechanical setup/fuelling.
