I just installed Bobby Wood's new TW-555 cams with his directional roller lifters. It feels like I have more torque and power especially at the high end. I am not sure what numbers they are making yet. I had 111 TQ and 91 HP a week prior to installing the cams and lifters. I went back to shop that did my baseline run to see what the new TQ and HP numbers are but he wasn't able to run it. He said it sounds like the transmission pulley bearing is bad and suggested I take it to the local HD shop and have it looked at and fixed under warranty. Once I get it back and have the results from the dyno run I will post the graph and numbers.
Has anyone else installed the TW-555 cams, if so, how do you like them?
You need to re-surface the heads in order to expose the worth of that cam.(and perhaps some head work)
10.4-5 would be the target area.
Wood 555/Our Stage III Heads/107"/OE t/body, and bagger duals..........110.2 hp/120.3 ft/lbs.
Carrys 100 ft/lbs from 2500-5700, and peaks at 3400.
Only 12 pulls(?) on the dyno it was tuned on.
