    difference in mass air meter size?

    Hey guy's what do you think the difference is between a 75mm and an 80mm meter is. Besides the obvious, for all you smart a's. Do you think it's worth a pound or 2 of boost? I'm thinking of just going with a 75 and saving the money here in the near future.

    I was wondering the same thing and was told it could be worth as much as 20 horse, however I took the cheaper road and went with the 75mm.

    never ran mine with a 75, but i would think filter size and flow would account for more than a 5mm airflow difference.

    May not be the obvious answer you were looking for... but just slightly less than 1/4" and slightly more than an 3/16" :D
