8psi on a cold night ehh... doubt it
when i had the stock pulley on when it was like 40 degress out i would pull like maybe 5.8 psi right under 6 and thats with my CAI
and now that ive upgraded pulleys/fuel system and its like 25 here right now im seeing like a little over 8psi on a 2.7 pulley
thats not bad sense its rated at only 4.5 psi with the stock pulley but the supercharger loves the cold weather
and thats probley why his car was able to keep up with a 13 sec car, supercharged cars tend to get quicker in the winter lol i wouldnt be surprised if hes running a low 14 with the cold weather
makes me wish i could race my car right now, damn snow but my car is away for the winter anyways ive been drivin my 4x4 blazer lol and every one knows how fast them things are haha
watch out hot rods here i come with my "blazer" im gonna plow there asses lol literaly
