If this is a Gen-II 997S w/X-51, it should be delivering closer to 350 wheel HP or thereabouts (with some variance from dyno to dyno). Crank HP is 408 from memory.

The result is likely so far down due to totally inadequate cooling during the dyno run. There don't appear to be any fans to control air intake temps and there also doesn't seem to be any fans targetted at the radiator ducts at the front of the car. Whether this accounts for a 40BHP loss, I'm not sure, but everything I've read suggests the latest ECUs are far less tolerant of less-than-ideal conditions than older units.

I'd be interested to hear anyone else's take on this one - particularly the tuning firms out there.

 

yeah - it looks low for 997.1 or .2

 

This is Gen 1, can tell by the rear lights in the video. Very nice result.

 

355 hp should have hp around 300 - 305 at peak

 

This is an X-51. Gen-1 should have about 330 wheel HP, Gen-II about 350

 

It is a 997.1, it seems a tad low for an X51 engine even though there are no fans or cooling. The weather is about 77 degree Fahrenheit so that also makes a difference...

 

hmm, This does seem low. I got 310 whp with GIAC, bypass pipes and X51 headers. I will be dynoing my car again soon since i added a few more X-51 goodies.

 

Its a Gen I 997s X51. what it delivers is pretty good for porsches in here (Gen I)

 

+1 Thats right if u consider the weather and the humidty

 

thank u

 

I'll dyno it again with fans on the front and the rear. Ill keep u posted

 

So your mds added maybe 5hp.
I did before and after and gained zero hp!!
Mods: evo headers, giac, evo intake

 

I think his baseline run was in the low 290's if I remember correctly.

My before and after was in the 302-305 range
