Rock crawling is short bursts of high rpm to pull up a climb. Often times I don't break 2k a whole weekend.
I wouldnt say I run it "hard", as most of the load is spread over the rest of the drivetrain through gear reduction. I do beat the hell out of that on a regular basis.
The gentleman above is correct about the octane level and got propane is the system I use on my other truck.
I ask about the gn turbo because of my low spooling needs. I'd like it to light up pretty soon relative to a drag car.
But I don't want to cram so much air amd be unsafe inside the cylinder at highway rpms.
On my next day available I am going to speak with cary at gotpropane. He has great customer service and I'll see if he has a preference on kit to use.
