GTP Stage 2 Flow #'s here on dirty heads.
Well if you seen my other posts about Hot Tanking & port matching you will note that when they "suposidly" Flowed my GTP's they were very dirty with carbon build up cause they never cleaned them first or at all for that matter 
. Here are the #'s they said they got...
Intake Side
Lift: Flow:
200 131
300 181
400 220
500 245
600 258
Exhaust Side
Lift: Flow:
200 110
300 154
400 186
500 189
600 197
How do these #'s fair compared to others?
