Do these car benefit very much from this? My dad is going to do it on his 944 ATX. I was wondering if it will give him very much more power?

Are you talking about a bigger TB? Not sure how you bore the TB.

more power? probably not a lot. better throttle response and maybe a little more power, but not a ton.

ATX meaning auto tranny? I don't think it would be worth his time to do that in an automatic.

ATX is autocross, right? If thats right, I think it might be worth it, as you will get more off the line response.
