[Korung 718]

Today got the car on the Dyno, I though I would share my results. Stock car base runs, 4 wheel Dyno.

Results 337.3 HP @ 5850 RPM, 358.1 lb-ft @ 3600 RPM.

Here is my 718 CS, stock vs Cobb stage 1 vs protune (with sports downpipe)

Max power at wheel for my car

Stock: 335HP @6100, 356 [email protected]

Stage#2: 363HP @6000, 377 [email protected]

Is it then on average about 30whp between stages? I was under the impression that stage 1 tune would yield greater results from stock. What am I missing .....?

 

[stephenc]

Don’t know what’s missing.

That’s what the dyno chart tells me. Yes only small gains even after I spend all these money and efforts.

But my butt dyno tells me improvement is significant and total noticeable

 

[stephenc]

Improvement at mid-range seems to be larger per my dyno chart

50ft-lb delta for TQ and 40HP delta for HP, almost across entire mid-range, and then gets less at peak

Mid-range is most used for street/highway driving. Maybe that’s why my butt dyno tells a different story

Are these results at the wheels?

Interesting to see that the stock 356 and 358 lb/ft (485NM) measured on the dyno is well above the Porsche quoted torque of 309 lb/ft (420NM).

Looks more like stage 1?

 

[stephenc]

Yes. At wheel.
