Retro Modern: Adding boost to your LS engine with a retro-cool 6-71 blower. Watch: 6-71 blower on 383 LS engine makes 753 hp on just 7.3 pounds of boost! ... As we found out, adding a dual-quad 6-71 supercharger to the already efficient LS made not only an impressive visual statement, but plenty of power as well.Feb 1, 2017
How much horsepower does a 671 blower add?
Driven 11 percent under, the 6-71 produced a boost curve that began at 4.2 psi at 3,300 rpm and rose to 8.3 psi at 6,400 rpm. This pulley combination produced peak power numbers of 602 hp at 6,400 rpm and 551 lb-ft of torque at 4,700 rpm.Sep 27, 2018
Does a blower add horsepower?
Blowers make horsepower and lots more torque than a standard engine. The amount of extra horsepower really depends on what your engine is like. On a 350 Chev, Weiand estimates an extra 100-120hp with one of its low-blow superchargers on an otherwise stock motor. ... The biggest gains will really be in torque.Oct 17, 2019
How is a Roots blower driven?
Rotary lobe blowers, also known as “Roots” type blowers, are positive displacement machines consisting of a pair of two lobed or three lobed rotors, rotating inside an oval shaped casing (Figure 1). One rotor is driven by external power while the other rotor is driven by synchronisation gears.

What supercharger does GM use?
An advanced, sixth-generation Eaton supercharger with high-twist four-lobe rotors is a large contributor to the engine's quiet high performance. It enables a broad power band with almost imperceptible operation. GM engineers created 370 different power simulations to optimize the LSA.
