Power Bus Vs Lockcock Bus
-
You know... those kind of power bus, pickup and accelerate very fast one... nearly fell down when dun hold onto the yellow bars...
Then, there are the lockcock ones, those with the old blue seats, engine not so good so doesn't move very fast... got alot of pple lagi worse
-
yesh, B9 vs others
B9 Use ZF ecomat 2 gearbox for some yes? Voiths pick up good also yes? brakes very zai yes?
ZYX -
SMRT merz 0405...
i luv the engine sound.. but some are weak already -
The VSOs sound powerful but that could never hide the truth of it's slow acceleration. The MK-II shows their power and speed the best but too bad they're retiring already.
-
Is it true that mk2 fot more power than other B10Ms in SBST becos they got no AC, so the bus is lighter and can accelerate and chiong better? i think someone say before, dunno true or not.

I think you have to remember your physics.
Less weight= more power
sleeker design = more speed
flat design = less speed
The B9TL will have a higher top speed in Singapore then the others as it has a sleeker design. Think of aerodynamics of a car and then you'll know. For the 3rd theory, gearbox and power not only determines top speed but the design also plays a part. Take Bus A and Bus B to have the same engine, gearbox but different design. Bus A is flat while B is sleeky. Take to a drag strip and test them. You'll see that Bus B comes in first. The Nissans tend to have a low top speed because of the front bumper. -
But do remember that the a/c taps power from the engine as well. A NAC bus would mean that the engine has no additional aircon compressor to drive.Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.

I think 60km/h hardly allows for significant air resistence.Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.

And yesh. The NAC MKIIs are the fastest among the B10Ms, I almost had a heart-attack taking a 74 WA MKII years ago. It kinda zipped from 1 spot to the other and the ZF gearbox was screaming like mad. -
I think Don't talk physics here. Not in science class lar boku-chan....Originally posted by Class 55 Deltic Fan:I think you have to remember your physics.

Yeah, I agree. If we are talking like maybe more than 150km/h, then air resistance will be more significant.Originally posted by SBS3625D:I think 60km/h hardly allows for significant air resistence.
The front bumper is so insignificant on the Nissan, it will have almost no effect at all! It's slow because the bus is old and lousy...
And the B9's are only slightly streamlined, makes no difference. -
One point i would like to make is that, in order for the UD to be slow all because of the bumper , the bumper would have to weigh almost a ton. That alone is impossible ,as the bumper is either a plastic or a hollow metal tube.Originally posted by Class 55 Deltic Fan:The Nissans tend to have a low top speed because of the front bumper.
The likely reason is that , it has a poor power to weight ratio. For example , 13bhp per tonne , thats power to weight ratio. -
hehe...i luved TIB581Y. quite special. lock at 1st and 2nd gear for quite longOriginally posted by patdog112:SMRT merz 0405...

Half of AMDEP SMRT buses are now locked due to traffic summons,Motorists/Passengers complains.

SBS1987Y- can speed up to 70km/hOriginally posted by carbikebus:Only a few can run.....
took SBS934G on Sv 161 and the bus sped on the second lane, overtaking a few vehicles.
Today, took a Dennis Lance (MY) on Sv 965 and it sped up to 80km/h along Gambas Ave and TPE
