I know i've kinda been procrastinating on this problem but my car doesn't boost properly when the motor is hot, i know i started a few posts about this back then but i never got a complete answer.... so heres the problem, i can drive on the highway for countless hours and boost 11psi psi just fine all day long, but say i'm driving around town and i wanna all of a sudden boost the car will only do 7psi. From here i could take the car back on the highway let it cool and boost 11psi again. My car doesn't overheat, the fan clutch is new, this is a na-t btw so i do not have a 10 blade fan or the aux fan in front of the a/c condensor. My radiator is the original and i do not have any aftermarket temp guages. So my question is if the car runs just a tad hot would that sumhow retard my boost. :1zhelp: thanks guys i really want to figure this out soon

also would it be a much worthy investment to replace the radiator even tho its not cracked or leaking, or should i upgrade to a 10 blade fan and/or turbo aux fan
