I'm assuming the rev limiter only works for the throttle.. meaning that it wont allow you to rev past 8200rpm but on the other hand, you can definately rev higher than that if you do a high speed downshift like what you did. And thats highly NOT recommended that you do it.. thats what causes engines to blow :P Bent shafts will be the result of excess revs that the engine can handle (which is set to 8.2k) For the love of your stivo, please dont do it again :D
