Will my combo kill the blower first or something else?

After asking Doug at ECS about this same combo he said shifting at 7000 would be over spinning the blower about 10,000 RPM he advised against this. He also said unless your going for 900hp this is not needed. lol
He advised to pulley up and stay within safe RPM and still should make great power.

This is a great question.. Only time will tell, and what works for your set up may be different then others.
I picked up 3 used pulleys. 3.6, 3.4 and 3.25. Put them all on and figured out belt sizes at home.
I have a 10 over Crank. I figured lets start off with the 3.25 and work our way back while on the Dyno. Like Unreal said, 20 min change with the car hot.
3.25 pulley, car was dropping boost off hard around 5,500 5,700 rpm and making more heat. Had to pull timing. Could have been belt slip but the heat would make me think it was over spinning as well.
3.4 pulley picked up one 1# at low RPM and held it till 7,000 RPM and had much less heat. Was able to add some timing. Let it here and ran it all year with no issues.
You should try the same thing. Nothing sucks more then taking your car home to make adjustments and then taking it back weeks later because they are to busy.
