Mmm... long day of tweaking a home depot DIY MBC apparently my shitty conical 15G can boost over 20 psi! hahah All that droving made me thirsty, so a nice rewarding budweiser (or 6) was in order.. by the way these are CANADIAN budweiser, and IMO are 10 fold better than that crap down.. umm.. there anyway, congrats to me for making that friggin spring and bearing I hack sawed outa my lil bro's toy work! ha - Graham
