A 2.7 would be find for daily driving ...you dont spend all your time in the redline so you wont be over spinning the blower and your right foot has all the control you need over boost ... I dont see the issue ??

why daily driving does not involve redlining ..which means there will be almost no strain on the blower regardless of the size of pulley

Yeah thats true, but I wonder how much of a diff i would see going from a 3 to 2.85? what do you gusy think?
Im thinking about going with the adjustable tensioner, because i may run the 3.0 the most of the time, then 2.8 at the track

Well if you are WOT for as long as it would take to over spin the blower with a 2.7 it wont matter if your car is ruined because your license will be taken away far before then for excessively breaking the speed limit ... if you are WOT that much for that long you cant say street racing is gay because that’s your daily driving ...

115kpa = 16.68psi
I'm hitting about 120kpa = around 17.4psi with stage 2
But remember we are not running mechanical boost gauges so not sure how accurate the boost levels really are.

you also have an intake which will effect boost levels
FAST06SS has a post on the pullies and exactly how much boost they will produce without outside factors like exhaust and intake ..

Yeah, that makes sense. The blower wine with just the intake was noticable but now it screams.

thats ignoring the fact that daily driving is not even going to come close to stressing your blower ..i dont care where you live you cant keep your engine near redline daily driving

I'm not trying to change your opinion just making sure its not based off mis-information

I have a 20K mile GEN5 on my Impala to prove it! 2.6" and 6500rpm MANY MANY times, NO issues!
