Sorry to say, but I cant tell how much in HP any specific item is creating, since the result is a combination of air intake and exhaust system modification. I previously planned measurements with every single item, but since the Akrapovic was arriving late, I had no time for that. Just compare my result with the results on the Akrapovic homepage and you can imagine how much HP gain the intake system is creating - even when it´s different cars, which are shown! I should be able to post the diagramm by tomorrow. Of course the airbox gives better throttle response due to bigger volume and most important - MEAN SOUND. Here comes a link to the Akrapovic page to give you an impression, hardfacts and soundfiles:

Have fun!

It's better to keep/post the Akrapovic exhaust info in the Akrapovic exhaust thread.

Absolutely right, I only posteted it here since I promissed unter #93 to post dyno results and I always stick to my word!

Here we go!
The result is the combination of CF inlet system, BMC air filter and Akrapovic Evolution TI exhaust!

So... 316.8 Kilowatts = 424.835798 hp.

There has to be a greater increase than just 4 hp from all of this!

316,8kw is the messured value, 329,2kw is the corrected value for pressure and temp! So we come to 447,7HP compared to 420HP stock and 443 Nm compared to 400Nm stock. Gain 47,7HP and 43Nm!!!
Sorry, I should have explained the German Dyno result to you!
