| He never did answer the question posted over a year ago and again more recently.
When I called their office last year Robin told me that 30+hp were observed at all boost levels but the reality came later when it was confirmed that gains are only present with a minimum of a 6lb pulley on lightnings.
On lower boost levels a loss of 40ft/lbs as well as hp losses were confirmed on dyno sheets posted last year.
I'm glad I didn't do it. These trucks need torque. |
