I just completed my before and after dyno run at Doug's Dyno power in Las Vegas.

The first run was completely stock. It shows 444 HP (WCF).
The second was 200 cat and x pipe. It shows 489 HP (WCF)

This is the first time I dyno'd any car and I'm a novice when it comes to reading these figures but something tells me these figures are wrong. I was assuming the stock would get around 425Hp at best and with the exhaust, 435HP.. I have attached the print out as you can see.
Run 1 (with exhaust)
Run 2 (stock)


Torque (run 1): Min: 321 / Max: 489 / Avg: 441
Torque (run 2): Min: 312 / Max: 479 / Avg: 389

HP (run 1): Min: 163 / Max: 476 / Avg: 386
HP (run 2): Min: 158 / Max: 433 / Avg: 344

 

Hopefully this attachment works

 

For comparison here is a 2011 997 Turbo PDK on my dyno.

 

What do you think is wrong? Are you correcting to get the 489hp? Because that is showing 489 tq

 

Nothing wrong with the numbers. Most of PDK's made identical numbers.

 

I find it hard to believe the exhaust made an additional 45whp (with WFC). I have yet tune my car which is my next step. I can only imagine the difference.

 

Squat-

According to the corrected numbers. The stock was 444HP and the exhaust was 489HP. That is a considerable jump, not that I mind. Here are both sheets.
