       Hi Paul, I have watched your P port video on you tube about a hundred times and think I can tackle this but I am wondering if you can give me some info on the exact place to put the port to get the correct intake timing.  I dont want to scrap a housing drilling in the wrong place.
       Thanks Kay C. Caldwell

       Here are the dimensions.

       We go straight in.

   Oh ya I remember seeing this on your web site....Was thinking it didnt have the dimensions....my bad
   Thanks again Kay C. Caldwell


Do you also make the exhaust port bigger?  I noticed on my GLS housing the exhaust looks smaller than the later naturally aspirated 13b housings??
Thanks Kay C Caldwell

As far as I can tell the exhaust port size has little affect on the HP.
