Not as great a number as I expected and I look forward to putting mine on the same Dyno that I have several baseline runs on. My gut feel is that the larger tires and consequent gearing change are tweaking the numbers downward but I’m waiting to hear back. Rick is running an OEM airbox/Alpine intake w/K&N drop-in filter and a one pipe in, 2- 2.5" pipes out MSL Max muffler.

My runs with the Brullen muffler and cone filter showed my Peak HP was 171HP and 195 ft lbs of torque. When I ran with the PowerVault muffler, HP was increased another 15HP to 186. The blower will only add to these numbers.

Thanks for going to the trouble Rick - now how about a run on the AWD Dyno to see what those numbers look like?
