Torque :37 Nm
Tyres :Michelin 225/50 R16 on OZ rims

ICE :Touch screen HU with 4 12" Sony subs
Misc :Custom paint job,fully adjustable rear
GT spoiler,Vented hood,Sunroof,Underdash Neon,GPS,Tacho and misc
gauges and no rear seat!

how can this be possible?
according to me an engine putting out 37Nm would have to spin at 24,760 rpm to get to 165 bhp.
a formula one car is rev limited to 18000 rpm, this car has to in something like formula zero.
at 3500 rpm with 37Nm torque the bhp comes out to be 25 (assuming that the car approaches its peak torque at 3500 rpm)
so in terms of performance this is not such a "hot" thing.

Guys,
I am not a photoshop guy so excuse.
Points:
1. lose the front fenders
2. get a bigger engine, install high mount carbs with big plenums and stack.
3. add a wide body kit for the back, get bigger wheels at back.
Something on the lines of badboyscad's second pic but have a look at Black Betty and go that way.

Explain a bit more please. Most of it just flew over my head

I know that Bhp and Torque are related to each other but did not know that a formula existed , thought it was variable.


There is another thread on this with sneak pics of the car.
The engine debate is there too !!

the formula is

HP = (torque x rpm) / 5252

HP is measured in bhp.
torque in pound-feet.

Well according to that most car bhp figures come out wrong. checked some for our cars and got different results completely

well its a bit tricky, because peak torque and peak power is achieved at different RPMs.
by the time RPMs reach their peak, the torque does not remain at peak level.
for example :-
the popular multijet engine produces 190 nm at 2000 rpm and 75 bhp at 4000 rpm.
190 nm is app 140 lb-ft.
so this means that at 2000 rpm the bhp output is (140 x 2000) / 5252, that is 53 bhp

but at 4000 rpm when the bhp is at peak, the engine is putting out how much torque?
it comes out to be (75 / 4000) * 5252 = 99 lb-ft = 134 nm.

that is why torque curve is important, the longer you are able to sustain it the more bhp you have in higher revs.

Quite possible Siddhartha, also if we read the other thread for which the link has been provided by me, more details about the engine can be found.

Reduced rear wheel size a little bit, widened rear wheel arch, added side pipe exhaust , side vent from MB slr, bodykit. and removed fenders.

The Amby as seen at the expo is sure to give Mr.Bond a complex.
