and its 150mph actually
my mistake but i was informed by a well known and experieneced tuner who uses a DD that it was 120.
i mean its hard to test a powerful car properly due to the load that has to be put on the rollers to contain the torque of the car.
i still dont understand why just because its a powerful car the dyno cant hold it back,we've had 500bhp cars and still been able to hold that power no problem,may be on dynos that wheelspin problems i can see a reason why it would be difficult to test
