from what i know turbos run better in cold weather right? anyway this kid is tellin me he is only makin 13 lbs of boost now that its real cold when normaly he makes 18...i was just wonderin cuz he raced my friend and it was real close and i just thought he might b maiin up some BS

 

seems odd...because as things get hotter they expand...that would make more boost on the needle (not exactly more hp but...) maybe the denser air before it is compressed allows for a larger quantity of air when it recieves its heat treatment during compression...hmm...[&:]

 

All FI motors make more power on cold dry days.. the air is a little denser and is cooler so air temps stay a little lower and the charger doesnt have to work quite as hard to achieve it.. but your not talking a huge difference.. Lots of guys will wait to dyno untill winter and hope for a dry day to make their numbers look the best.. and it should make no difference on the PSI its putting out.. you have to actualy adjust a turbo with a boost controler.. its not like it will auto sense the temp and chage its output..
