The tests Cart Car & other mags have done in the past comparing a 6-71, B&M 144,Weiand 142?, Paxton super chargers & so-on, when they slowed down the 6-71 blower for low boost of 6-8 psi IIRC?

The 6-71 made the least HP & really added a lot of weight to the car.
The smaller faster turning blowers all made more HP & were more effcient (SP).
