turbormonkey Posted January 14, 2008 Report Share Posted January 14, 2008 Hi i was reading an article where it stated The 850 Turbo Wagon is one of the fastest production station wagons in the world, capable of 250+ km/h (160+ mph) when ungoverned. Production models of the wagon and sedan were electronically governed to approximately 142 mph (229 km/h) Why did they govern the engines when their isnt that much difference in speed. If you run a euro ecu can you acheive the 160+ speed mark or can you have your current ecu modified, its just a question that intrigues me, if any of you vsers can provide a little insight. Do you need a remap to acheive the 160+ mark. Link to comment Share on other sites More sharing options...
maiku Posted January 14, 2008 Report Share Posted January 14, 2008 cause it's part of the law?depending on the chip, the speed limiter may be removed Link to comment Share on other sites More sharing options...
MikeG Posted January 14, 2008 Report Share Posted January 14, 2008 I don't know for sure, but many vehicles are governed in that same ballpark (135 for my wife's MINI ) and it might have a lot to do with US government regulations. I read recently that the EU is considering a law that will govern all vehicles in EU countries to 100mph max.Another reason might be that even the regulated speed and the max speed sound close, RPMs will jump up on the dangerous side at the actual max speed. So Volvo may want to help you remember not to run at full redline for extended periods of time...My tuppence. Link to comment Share on other sites More sharing options...
Yellow95 Posted January 14, 2008 Report Share Posted January 14, 2008 Some cars are also governed to keep them below speed rating on the tires they are delivered with.Gary Link to comment Share on other sites More sharing options...
Auburn T5 Posted January 14, 2008 Report Share Posted January 14, 2008 All valid points gentlement but I think Mike hit the most important nail on the head and that's even on a stock engine/ecu, running the car full throttle long enough to hit 150mph+ is the quickest way to kill an engine. Somewhere in his book, corky Bell talks about how much faster a full boost run down the 1/4 mile track will wear out an engine vs a standard drive 1/4 of a mile.I would suspect that a romp to 160mph would potentially kill an engine with a lot of miles or an engine that isn't in top running shape... or at least bend a rod or two in the process.

Pops Racer Posted January 14, 2008 Report Share Posted January 14, 2008 Plus I wonder how the stock wagon suspension would react to a directional change or adjustment at that speed. Not well I'd imagine. Link to comment Share on other sites More sharing options...
