Question: I did the airbox mod (drilled holes in airbox cover) and reportedly it gives you an extra 5 hp and it does sound great. It feels quicker to me, and I don't know if that's all in my head or not because of the sound, etc. My question is can an inexperienced butt like mine (had first p-car x 1 year, tracked once) notice a 5hp difference in street driving only? I've also read that the running the AC subtracts 5-15hp, but I really don't necessarily notice that drastic of a change. Thanks!

I have the "sound package" on my 993, which is basically the same thing as drilling holes in the airbox - as far as I was aware there is no increase in HP - it was all about sound - that's why it was called the "sound package"?

I'll second Marv. When I turn the A/C on in my Golf TDI (around 90 horses) I can feel every hair of those five to ten horses slipping away from me. On the 993, the difference is much less noticable.

Whoever told you that drilling holes in your airbox gives you a 5hp increase doesn't know what the heck they're talking about. It's worth about 0.01 hp. But you wouldn't likely notice 5hp increase anyway.
15hp? Yes, you'd probably feel it. Sometimes I forget to turn my A/C off at the track, but I figure it out in about 3-4 turns. That's probably about 10-15hp I guess.

You cannot feel a 5 HP difference on a 270+hp car.
As Eric said, the drilled airbox will not make any difference in performance, the sound will make you feel like it does, it is normal.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
On 993TTs (particularily modded) the drilled airbox makes a substantial difference.
