We set the lash at 0.17 inch, which we subtracted from the gross lift number to produce a net lift of 0.613 inch. The Manifolds Edelbrock Torker II The Torker II lives up to its name with good torque below 4,600 rpm. After that, its subdued carb height hurts horsepower. As one of the shortest manifolds in the test, it offers good potential in low hood applications. PN 5001 Price $149.95 Peak HP 492 at 6,000 Peak TQ 501 at 4,400 Average TQ 466.5 Carb Pad Height 4.55 Plenum Depth 3.38 inches Weiand X-CELerator As this was the shortest intake in the test, we were surprised it achieved 505 peak horsepower. It also managed to make an average of 472 lb-ft of torque, which is respectable. PN 7547-1 Price $165.95 Peak HP 505 at 6,200 Peak TQ 502 at 4,500 Average TQ 472.0 Carb Pad Height 4.00 Plenum Depth 2.95 inches Edelbrock Super Victor 23 The results for this manifold were puzzling, since it lost more than 10 lb-ft of torque in the midrange compared with many of the other manifolds. While the Super Victor 23 generated good peak horsepower for its height, its low average torque is a detriment. PN 2925 Price $249.95 Peak HP 523 at 6,100 Peak TQ 506 at 4,500 Average TQ 477.4 Carb Pad Height 5.50 Plenum Depth 4.05 inches Weiand Team G We divided the average torque by the carb-pad height and discovered this manifold really rocks for its height. It makes more than 500 hp yet is one of the lowest manifolds. It would probably respond well to a carb spacer if there were room under your hood. PN 7530 Price $209.95 Peak HP 524 at 6,200 Peak TQ 507 at 4,600 Average TQ 478.4 Carb Pad Height 4.50 Plenum Depth 3.78 inches Edelbrock Victor Jr. Edelbrock has probably sold more Victor Jr.'s over the years than the rest of the field combined. Despite its relatively low carb height, it offers great average torque and peak horsepower. For a car with a restricted hood line, this manifold would be a wise choice. PN 2975 Price $234.95 Peak HP 523 at 6,200 Peak TQ 507 at 4,700 Average TQ 479.2 Carb Pad Height 5.04 Plenum Depth 3.91 inches Professional Products Super Hurricane Just for the record, if you look at the results for the ProComp Shootout Pro, you'll notice they are very similar to this Professional Products Super Hurricane. That's because they are same manifold, with just slightly different part numbers. PN 52037 Price $258.95 Peak HP 530 at 6,200 Peak TQ 504 at 4,700 Average TQ 480.2 Carb Pad Height 5.85 Plenum Depth 4.49 inches « | 1 | 2 | 3 | 4 | 5 | 6 | » | View Full Article By Jeff Smith Enjoyed this Post?
