I wonder just how much of the claimed 25-30hp gain would you say is coming from getting a remap and how much is coming from the carbon airbox design?
The Evolve website claims 15-24hp gain alone for just the remap HERE
And for only $799, it might be an excellent deal!
I know the sound of this carbon airbox is awesome. However, the cost is way way out of my price range. |
The filter fits between the plenum and air intake, where the two meet.
As far as the power is concerned, I plan on putting my car on the dyno to see how well the numbers mirror what I feel. I've read that people who have installed only the airbox, untuned, gained around 15HP. With the tune I'd guess the total power gains are likely right around 35HP. For those keeping score, about $100 per HP. HA. Naturally aspirated modding is a cruel mistress.
Like I said in the write up, it's definitely not for everybody. The value is primarily in the difference it makes to the driving experience overall, not the power gains. Honestly, an Eventuri or Gruppe-M intake is the more sensible solution for most people. But, now that I've experienced the CSL style airbox in person, I'd never be able to go back.
