I know a guy, had his own bench and then audipro 'metric deal' or something like that. He could see before and after to know if he made improvements or not or hurt it...however it didn't show the same flow numbers as another ind std bench does. That said ..time went on and the industry went from 25 to 28 'to time the era'... it was great, till people were aware more of flowbench testing and the industry standard of flow ratings. His numbers didnt jive and people got uppity about it...
He'd say..."the before n after shows 43 cfm gain"... And the customer would say..""but you cant tell me what the head flows, at the industry std""
He bought another setup, "superflow 600"
Point is don't brag about number that don't translate accurately, people who aren't very aware will think a head can flow near 200 cfm @.100 lift with a 2.02.
If you have a before n after and your bench isn't @28....just share the gains and we can figure from stock head where abouts you may be...but if you wanna ASSUME we know it's not and then gripe and say We assumed..well we aren't greasing very well here. No one is picking on you. We just need to make sure YOU aren't confusing people who are learning about this for the 1st time by posting the total flow which is immeasurable for us and therefore useless!!
Share the gains, not the misleading results from your crackerjack box bench. Sorry in advance if that sounds insulting to you. You seem a bit riled though..
Thanks for sharing.
