ok, I think you might need to change a parameter.

Try the following filter in your functions file

function bbp_increase-forums-per-page( $args = array() ) {
$args['posts_per_page'] = get_option( '_bbp_forums_per_page', 150 );
    return $args;
}
add_filter( 'bbp_before_has_forums_parse_args', 'bbp_increase-forums-per-page' ); 

Come back and let us know if that worked.
