90dpscoupe, the limiter only works when the engine is using its own power to rev too high. Rev limiters cut out spark or fuel, neither of which was needed when the cars momentum is turning the engine. If you get going 90mph and shift into 1st gear, cutting spark or fuel out is not going to stop the engine from being turned at the rpms needed to go that speed in 1st gear.
