heavy vehicle to cars
-
I was thinking abt this while doing my office work
i thought,supposely engine of vehicle can fit into a car
lets imagine it can
heavy vehicle have engine which produce higher horse power to that of a car
however,bcuz of the weight of the vehicle,the horsepower are evenly distribute
for eg.
assumtion with the no.
X horpsepower to 1kg
vehicle weights 300kg
this means 300X horsepower to move the heavy vehicle
a car requries X-Y horsepower to move 1kg
lets take X-Y=T
car need T horsepower to move 1kg of its weight
and if the engine were to be used in car
i said assume it culd b fitted and settings/ecu were alrite
then wuldnt there be excess horsepower/torque?
wuldnt turbo kick in at a lower bar?
I juz need scientific explaination not flame -
those engines are designed for a diff purpose la....truck engines are never designed for speed in the 1st palce....more for heavy loads (thats where diesel comes in) even it has say 450 BHP for eg its also there for heavy loads and not for pure performance like in cars...and of czo they are never light...I think if u ever try 2 fit one in a car the front would prob buckle at the weight....

Go read up on power-to-weight ratio. You'll understand better.
-
diesel engine have low torque sia...3100cc red line at 4000 liao
-
large engines cannot put on small car. ur acceleration will suffer. the engine one stroke want to take how long sia. and ur chassis shld shake liao. and the weight will not balance out.
dun rely on bhp figures alone. a bus/truck engine has the same bhp as a ferrari but u cannot dx and expect it to run.
for e.g. a Scania 113 truck is 11 litres. each cylinder also chao chao give u 1.8-litres. tat is the disp for a 4-cylinder car liao. u wan to use 4 times the power to the equivalent of one unit of distance for wat sia~ -
wah your maths impressive
+5 man
but then hor, engine can fit is can fit lah , end up your car heavy like sh!t
then accelerate slow like fu&K. but one thing can guarentee is the torgue damn zai, i think can drag your family liao. hehe -
No need such a big engine lah. Your Skyline's one is powerful enough. Don't have RB100DETT lah. The engine bay also cannot fit such a big one. Ask Bunta for help lah. [email protected]

fuk off la simi buntaOriginally posted by Kr0n:No need such a big engine lah. Your Skyline's one is powerful enough. Don't have RB100DETT lah. The engine bay also cannot fit such a big one. Ask Bunta for help lah. [email protected]
low life like u keep talkign abt ID for wat
that kid show
go back to ur room and watch and fuk off from my sight la -
so in short it has been tested b4Originally posted by yoshitei:Back in Â’94, I there was a factory build Ford Mustang Boss running around with a 10-liter V8 engine fitted into its bay.
The car – if that is what you still call it – made around 850 bhp and managed a 0-60 in less than 2 seconds but the quarter mile run hovered around the high side of 11 seconds.
And by the way, if youÂ’re really interested, it was only used on the drag strip and used a C9 3-speed transmission hence the quarter mile time.
Point is; mating truck engines to cars is nothing new. But what do you intend to achieve? Power?
Force induction solves your problems faster and cheaper without the weight penalty and the cost factor of machining new mounts for almost everything in the engine bay of the car.
The larger your engine capacity, the lower your RPM. Compare a 400cc motorcycle engine and a 2000cc motorcar engine in the RPM department and youÂ’ll see the difference.
Increasing RPM on a large capacity engine is not impossible. The only constrains are financial. Do you have the money to machine a bullet proof crankshaft and con-rods? -
U dun even have a scientific mind to even be able to think of such thing and ask whyOriginally posted by Kr0n:No need such a big engine lah. Your Skyline's one is powerful enough. Don't have RB100DETT lah. The engine bay also cannot fit such a big one. Ask Bunta for help lah. [email protected]
go back to ur clique of ppl who juz wanna think older ppl know much than younger ppl bcuz of their age
all im enquiring abt here is suppose everything,ECU/fitting is ok
u cant even udnerstand eng and like jumping to conclusion
have u complete psle?
u shyt face...juz fuk off and die if all u know is the name of car
im going deeper and talking abt experimentation and theorectical stuff
until ur on the same frequency as me...fuk off -
Aiyoh sorry sorry. I'd better tell my engineering lecturers that they've been teaching rubbish.Originally posted by olala:U dun even have a scientific mind to even be able to think of such thing and ask why

Oh, and I'm sorry I can't even understand English as well as you do, and that I'm not as deep as you.
But I still think your Skyline's engine is powerful enough though

wat is Y??? -
Y is the hp of the car
but when u fit the engine of the heavy vechicle
there will be excesss torque so
i denote it as X-Y
Z is the hp of heavy vech
Y is hp of car -
If using Truck engine to mount into a car, first problem.. weight. The car chassis may just break up. If I not wrong, a bus engine weights 8 times more than a normal sedan. Eg. car=180kg, Bus=1.1 tonn.
Desiel engine are meant for power, not speed. They got the power to drag weights, even if theres no weight for it to drag, you still will not find it running fast.
If using truck engine, can you imagine the wear and tear it has on the car?? How long the car will last sia?? -
Why not put in a jet turbine? I'm serious!
See, can be done. I think you should forget the heavy vehicles engine, this is the sh1t!!!
Alternatively, you can break many years of convention and logic, and use your ingenuity to put that heavy V engine in. -
Aiya, where got car weight only 180Kg. If got, the car surely can fly one.... so light only. I think only motor bikes got this can of weight.Originally posted by drumstick:If using Truck engine to mount into a car, first problem.. weight. The car chassis may just break up.

Also, did anyone read last saturday life section (or is it the one before last week) on motorbike Trump. They throw in a 2300cc engine into the bike. Now, this bike can really fly. -
I still agreed with drumstick that the huge truck engine is only meant for power to drag heavy load. Thats why my dyna dun need first gear to move off. Use second gear also can.
But if i got heavy load then i will get to use the first gear.
Also those truck engine has a 8 speed gear box, so try fitting that into your engine bay (which is damn big loh. I dun think you want me to mentioned about ships' engine. Just the piston alone is already 3/4 a ton, haven't add the connecting rod, bearings and awhole lot of other things). -
Is this the new Bat Mobil that they have been talking about?Originally posted by Kr0n:Why not put in a jet turbine? I'm serious!

u probly be frustrated by the 2000 rpm redline if u choose a bus engineOriginally posted by olala:I was thinking abt this while doing my office work

eh but if u compare a small 1000cc car to a big 2700cc car there dont seem to be any different in the rpm range le..the only different i manage to spot is that the redline is slightly lower for european cars compared to japanese's(6000rpm for Merc E200 and BMW 320i compared to 6500rpm for everyday jap cars like Sunny,Lancer etc etc..im not comparing hp here btw)Originally posted by yoshitei:The larger your engine capacity, the lower your RPM.

I meant the engine weight. Not the gross weight of teh whole car.Originally posted by Disappointment:Aiya, where got car weight only 180Kg. If got, the car surely can fly one.... so light only. I think only motor bikes got this can of weight.

higher displacement engines are more difficult to be built to rev high.Originally posted by ceecookie:eh but if u compare a small 1000cc car to a big 2700cc car there dont seem to be any different in the rpm range le..the only different i manage to spot is that the redline is slightly lower for european cars compared to japanese's(6000rpm for Merc E200 and BMW 320i compared to 6500rpm for everyday jap cars like Sunny,Lancer etc etc..im not comparing hp here btw) -
If olala puts that turbine inside his Skyline he can rev it till 20,000rpm!
