and he was telling me about working a Porsche event where he was doing the preinspection of the cars (open glove-box, trunk etc) to look for loose things before the cars went out on the track. He inspected a white RS5 that a woman was driving and opened the trunk to see a nitros bottle. Some serious system - I wonder how long the engine will last.

... The design of the RS5 V8 sounds like adding nitrous makes a toxic stew. The piston speed of the 4.2 reaches near F1 velocities with very high redlines for a production motor. People get frustrated with the RS5 because it feels a tad pokey off of idle. But for crying out loud, if you want a stoplight crusader, get yourself a Hellcat or a ZL1. The RS5 shines on a canyon run of fast sweepers and elevation changes or a comfortable 600 mile run to San Francisco. Once the rpm's are up, the car literally flings itself from corner to corner. It is so linear that you don't have the same sensation of speed as the S4/S5. I have taken to having the digital speed readout showing so I can catch a glance as I enter a corner (always faster than I think).

So the question is: "when it blows, does a piston come up through the valve train, or does a connecting rod blast through the oil pan?"

Happy Motoring Reggie

My vote: A single clean 84.5 mm hole in the hood.

If the car had a heater on the bottle, was there pressure releases, was there a scatter shield around the bottle, etc.?

She passed because everything was bolted down. The inspection was just for loose items that can be tossed around driving hard
