Have seen that formel in a old thread and it makes me wonder how correct it is? You who haved dyno please write down your air flow gram/sec and the dyno rwhp result,
and for you that have AF pounds/minute please multiply with 7.56 to get grams/sec. Also write if its a A4 or M6 and if the maf is descreend or ported.
Thanks

 

I cant possibly see how this is accurate... It may give you some idea of how well your heads are ported and how well you engine breaths but there are many more factors to determine horsepower.

I have 318 AFGS @ 5900

 

hmmm
"It may give you some idea of how well your heads are ported and how well you engine breaths"
isnt that whats making power if air/fuel ratio is right?

Here is a link to the thread http://web.camaross.com/forums/showt...highlight=afgs
and thats what made me wondering about Afgs/hp.
have 317 afgs 6150-6200 rpm
