We did a twin motor upgrade for the Warn M8274 winch recently. The Gigglepin Kit came with 2 Warn 9.5xp 6hp motors, A pro series top housing made from sand-cast and heat treated aluminium with 40% speed gear, we also opt for the up-rated main shaft as well as the heavy duty brake shoe. Unlike the single motor M8274 , this upgrade will be without a free spooling unless we get the GP Free Spool Drum, the additional cost will defeats our purpose of just upgrading the M8274. Free spooling will be critical for time based competition but for our application which is normal off road wheeling, we will stay with this setting for the moment.
All winch motor draws much more ampere than the rest of the electrical components in the vehicle. Base on manufacturer's specification , a single Warn 9.5xp 6hp motor will pull around 71 ampere without load and up to 482 amp on maximum load. A stock Jeep Wrangler with a 117 amp alternator will not be able to provide enough power for two motors. A higher output alternator is needed , but of course we do not expect a less than 3 ton jeep to put the two motor on maximum load during self recovery.
Over-volting the motor will increase the speed of the winching operation as well as reduce the amperage drawn , but also reduce the life of the motor. Warn motor unlike the Bow motor may be less suitable for over volt. We suspect that over-volting also have effects on the Bow motor over times. Like we said before, we have no such requirement at the moment.
