Hello I just dynoed my 498 with the X-C96 yesterday 625 horse 575 torque. at 3700 it was making 559 for torque . i also compared it to a team g intake with a 1050 dominator team g made more power but average numbers it was 1 hp above the cross ram . For a 1 horsepower I'll take the wow factor with the x-c96. My build is a solid street roller not the biggest but idles at 10 inches of vacuum and is a dual quad that starts with a simple turn of the key . I put 1200 miles on this motor before having a oil pick-up issue . motor repaired and it purrs like a kitten at 11 to 1200
