Comparison of Weiand Roots-type blower and Paxton centrifugal blower. The Weiand produces more torque at lower RPM, but less HP at higher RPM. The Paxton produces less torque at lower RPM, but more HP at higher RPM. None of this is a surprise.
Comments:
- While Paxton and Torqstorm are similar designs (belt driven with step-up gearing) I have no idea how they compare in torque / HP curves on a given engine
- Centrifugal superchargers produce less low RPM torque than Roots or twin screw blowers, but that's should be more of an issue for heavy vehicles or towing than it is for Cobras. It's easy to over-power the rear tires on a Cobra - is there any real reason to make it even easier?
- Low boost (5-8 PSI) superchargers seem well-matched to a lower compression engine as an alternative to replacing the rotating assembly - though packaging will always be an issue in a Cobra.
