Anaysis ERROR!
Depending on were you compare the curve its
+12WHP now!
Gator: thanks for the post fix up.
I predicted up to 10WHP on the monster
Plenum thread and was not really expecting a huge improvement although was wishful of a good gain. So that worked out about right...unfortunatley. I guessed a lower figure than the 20WHP advertised based on that that I already have mods and marketing info is usually best case results. Oh well you get that I suppose.
I can really feel the torque improvement. I was not really expecting much change but I think thats its more noticeable than the top power increase. So its better but not like its a huge improvement or anything.
Will I keep it? Well the cost to remove it now and send it back is a bit much. Although the mod costs a bit, compared to the price of the car it all still works out much cheaper than a 997 S. Now it goes better and looks better!
I also examined the throttle body. Based on todays findings IMO, no mod on this will result in more than 2 WHP improvement. The walls are already thin and to machine it to bits will only weaken it.
