Mackmann Posted June 28, 2011 Share Posted June 28, 2011 i have a 2006 CV713 with the 460. I get the same MPG 4.5-5. The fan is loud as hell but for 800 bucks they do sell a 2 stage fan. Im waiting for the one i have now to take a shit so i can get the 2-stage. The 2 stage is not loud at all. Your right the 460 is nothing to brag about. My dads C-15 -475hp walks all over it. Its enuff for me and what i do. But ytou would think it had more balls. Off the line its a dog. I got 4.30 gears and a 13speed.One more thing about that damn fan. It robs alot of HP. I been in hills and had to down shift when the fan came on. Quote My Facebook. Feel free to add me as a friend. Just tell me your from BMT.

Mackpro Posted June 29, 2011 Share Posted June 29, 2011 The best average MPG that we have seen with the AI engine in the CV/CT's is 5.2 and the guys were happy to see that.

In the heat of summer (90+ degree days) the fan stays engaged to much on the slightest hills. He's bringing it back this week to put the old program back in it.
