Everyone scoffs at the vortech's torque when in reality it's the SC kit that makes the highest hp with the lowest boost pressure.

Actually, the Rotrex kits make more than that pound for pound, on E85, as does the Edelbrock/Harrop.
Here's an edelbrock kit on the standard (CARB) pulley which makes a *maximum* of 9 psi, with a Delicious flex fuel kit. Stock header, stock front pipe.
The Vortech was better than the Innovate kit (which was first to market), but has been surpassed by the kits released afterwards.
To put it in perspective, I make more power at 5.5 psi boost at peak power, on ethanol (300whp), with my GReddy turbo kit.
That all being said, lower torque, and lower power, means less stress, and a high probability of more reliability.
