ConnClark,
I'd just point your land yacht up one of your mountain roads and let it rip a couple times a year. It should get plenty hot!
I don't think they meant having your car at anywhere near full throttle on a dyno for 20 minutes. I doubt many dyno's can absorb that much energy (100hp for 20 minutes!) and probably something under the hood would melt, catch fire, or atleast half the life would be cooked out of many rubber or plastic parts...
Even free wheeling at 4000rpm for 20 minutes should have the exhaust glowing brightly which I think is what they meant to have done...
Ian
