ok i must have been too tired to read it correctly
Tim Frost got around 85% increase in peak horsepower using the 4AGZE blower and stock pulley but taking the turbo off and supercharging a 3TGTE would give you less of a power increase, when you could have spent the money upgrading the turbo.
I like the idea of supercharging a 2TGEU, apart from the mounting and computer issues. A guy in brisbane used to get 13sec quarters by doing a blow-thru 4agze blower on a stock 2TG setup, running around 16psi. The engine didn't last long but he got some good times out of it.
