Big Turbos: Lag vs Boost threshold

[Goat Blower]

They've had huge advances in turbo design and sizing in the last 7-8 years. And the now common big blocks, the 2.3 and 2.4's also make a big difference. My 3575 2.4 spools only a bit slower than my old 20G 2.0 setup. Good turbo design and extra displacement make a world of difference over the old setups. I wouldn't want a big turbo on a little 2.0, but the extra .4 displacement adds ~50 whp, ~70 ft/lbs of torque and spools a big turbo 400 rpm faster.
