Most data on head flow that you will find will be more for selling there heads then useable data , the bad thng about the PC "how much HP will I have " doesnt take into account once you bolt a intake manifold , TB , intake pipe and filter , Header , CAT etc this flaws the entire system , I own a Dynojet Dyno and I beta tested a few of the PC/HP software out there and found them all to basicly be worthless
Just for the heck of it one day I have a 1.5L Engine making over 1000HP which would never happen on 93 fuel but it said it would
It said my Focus on stock cams wouldnt hit 500+HP as well but it did
If your using this to build an engine and with the plans of it making that HP/TQ you may be disappointed
