Attention Roe Blower owners: 12lb pulley update

[utahviper]

Now that I have driven my car with the 12lb pulley for a little while I can say that it is not ready for the every day driver. The intake temperature when it is 90+ degrees outside is around 260 degrees. That is entirely too hot. With my 8.5lb pulley the intake temperature never got above 200 degrees unless you were under WOT. Before you can install the 12lb pulley you have to install the intercooler or a bigger bypass or another bypass. The only reason I am able to drive it is because I can purge my intake with h20/methanol to cool it down before WOT. I don't need to do this at the track because I always ice my intake.

I still do not know the actual dyno numbers or power increase. Seat of the pants is lets say 60RWTQ and 40RWHP. Not a lot but definitely a difference.

How small is the 12lb pulley(LOL)? Do you have issues keeping the belt on?

I use 50lb injectors.

2.3" is the size of my pulley. I don't really have any belt issues. The only problem I have ever had is the power steering pump bracket has broken twice.
