How fast is the Dash 8 - Q400?

How fast is the Dash 8 - Q400?
Anyone care to satisfy this old Bonanza pilot's curiosity?
What is the TAS in cruise of a Q400?
How does this compare with the "non-Q400"?
What did they do to get the Q400 to GO?
My interest was triggered by the fact that, over a short leg (<200 nm) the Bo is generally not too far behind older Dash 8's, but I recently "raced" one of the new ones from Mackay to Rocky. I took off from YBMK behind one with only the length of the runway between us, but it was taxying YBRK for departure before I had landed.
Seems very quick!
Are the QL Dash 8s breeding? There were at least 8 of them on the ground at YBBN today !!!!

bit faster then the Q300 bit slower then the B737, bigger engines make it go faster, and the red tail makes it go a little faster - note to designers if they painted it all red it would go even faster.

TAS of 360 is fairly common. Max cruise is around there too. PW150A engines are actually based on PW's 4000 series turbofans apparently. 3750 odd KW of power out of each of the buggers! Roughly twice as powerful as older props, and uses significantly less fuel. Now who said props are for boats...

Bout 350/65 Kts as reported is correct! The bonks have the same core as the J-Model Hercs operated by the RAAF. Qlink were looking at replacing the leading and trailing edge de-ice boots and utilising bleed air to heat the wings in icing conditions if required, thus extending the speed to an estimated 385kts! Yep this is one fantastic machine,
however will Mr Joe Public continue to commute in one when VB start going head to head against this a/c (with there Ejets) one has to wonder?

Is it just me or has anyone else found them horrendously noisey inside? I liked the inside fit out of the new 400s, but on a CBR SYD - sector the noise was almost unbearable. Couldnt wait to get off.
Never found the noise as bad (memorable) on earlier models.

Will have to go for a burn on one and see for myself

bit slower then the B737
Even on our shortest sector ( 270nm ) we would be on the ground when the " boat " arrived in the circuit ( notwithstanding shonky ATC ala CB-SY )

Trailing edge deice boots?
What are you smoking?

How much do you have to slow down when you start hitting a few bumps down there at 20k?

If this is the case I hope that you requested a wake turb waiver from ATC as this sounds like a break down of departure wake turb. Light behind Medium you gotta have 2 mins or 5 nm

Err, I think medium category starts a little lower than 25,000 kg's, say 7000 Kg's (with thanks to flightfocus)...
