Gpm depends on how fast ya spin it, but yes I was thinking of a warn or Ramsey and in my head about 12 gpm, with is, what like 75% of 17gpm? So yeah, excessive
Either way, easy peasy. And far superior for long use and questionable heavy use versus electric. Too much? Just won't lift. Won't burn up anything or stress any parts
The problem is finding a pump that small and can that can rev up, the pump I was looking at was a 1.45CI pump that made 17GPM at ~2900 RPM on the pump with a 6" pulley (pump redline was 3000 RPM).
When the pump was engaged they would have to keep the engine under 3000 RPM (assuming a 6" pulley on the crank), so limited or no winching while moving.
At 2000RPM it would put out 12 GPM, at 2900RPM with 17GPM and 3000PSI it would use about 30HP (in electric motor HP whoch Surplus Center claims you need 60HP on a gas motor to equal).
The other issue is that winch speed would be directly proportional to engine RPM, sitting at idle it would be slow whereas a electric winch won't care as long as the alternator can keep up.
The alternative would be a closed center hydraulic system (which can vary the GPM output to match the load and the pressure always stays high), but if you think that a $750 open center pump is bad, you should sit down before you look up one of those pumps.
Either way, a 12GPM and 17GPM valve are not going to be much different in price, neither is the pump, the tank, the cooler, etc. The lines and fitting will be a little cheaper, but I would be surprised if they were more than $500-800 less for everything but the winch to build a 12GPM system vs a 17GPM system and all my prices were shopping at Surplus Center, eBay, etc vs going to the local hydraulic shop to get what they keep in stock which will likely double or quadruple the price.
Now, if they JUST wanted to use hydraulics to lift/lower the boom, that they could run off of the power steering pump and it could be under $1000, but adding a winch that may run constantly in the heat adds exponentially to the price.
Given all that, they can probbaly afford to buy a spare winch and store it behind the seat (or use it to set the boom height before letting the chain take the load) for what they are saving in going to an electric winch.
Not sure their chopped up truck has enough ass to justify a 30k winch. I dunno. I'd take a 10 or 20k winch Hydraulic over an electric for random picking up of cars from holes
In the video with Heavy D they said its sitting around 9k right now which appears to have most of the heavy stuff on.
