i find that hard to belive!! i know what artical you are taking about and i have read it alot of times! 9lbs is 9lbs and it will put out pretty much same amount of power no mater if its a super charger or a turbo!! and 9 lbs in a si does not put 272 hp to wheels!! most i have ever seen is like 23-240 with about ~9-10lbs. so somthing is up with that setup! an i think the public is missing out on some value info!!!
