Well since nobody wants to answer, i'll take a guess at 180 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>? Take that as a good middle #

160 sounds resonable, like i said I guessed cause nobody would give you an answer <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

SOME PLZ TELL ME IF MY ENGINE IS DYING?
