Motaleira, 338bhp per ton?

nitram38 - 25/4/09 at 09:36 PM

I found this calculator on my travels here

These are my "theoretical" stats based on estimated 160bhp (engine 182bhp on a bike):

Power at Flywheel (BHP) : 160
Weight without Driver (KG) : 480
Power to Weight Ratio (BHP Per Ton) : 338.68
0 - 60 (Secs) : 3.80
0 - 100 (Secs) : 10.19
60 - 100 (Secs) : 6.39
Quarter Mile (Secs) : 12.24
Terminal Speed (MPH) : 109.61
Drag Strip Quarter Mile (Secs) : 12.14
Drag Strip Terminal Speed (MPH) : 110.95

What are yours?

nice !!

Weight without driver? Not terribly relevant unless it's an RC car.

blakep82 - 25/4/09 at 09:40 PM

0-60. 0-100. 60-100 all completely irrelevant without info on the gearing.

anyways, here's mine

Power at Flywheel (BHP) : 180
Weight without Driver (KG) : 850
Power to Weight Ratio (BHP Per Ton) : 215.16
0 - 60 (Secs) : 5.19
0 - 100 (Secs) : 13.59
60 - 100 (Secs) : 8.41
Quarter Mile (Secs) : 13.61
Terminal Speed (MPH) : 100.04
Drag Strip Quarter Mile (Secs) : 13.51
Drag Strip Terminal Speed (MPH) : 101.21

but it;s all guess work i don't know how much it'll weigh. i'm just going by the ballasted weight of the racing ones, and a guess at the power of my engine

nitram38 - 25/4/09 at 09:42 PM

I was more interested in the power to weight and 0-60 times.

Aren't cars calculated that way?
If not, add you weight in and do a calc.
It's only for fun!

blakep82 - 25/4/09 at 09:45 PM

but the 0-60 times are going to be affected by your gearing. you could have 600hp, but if your diff if 600:1 and a 5kg car (ok, a bit unlikely ) you'll never make 60mph

nitram38 - 25/4/09 at 09:48 PM

How the figures were derived here

cloudy - 25/4/09 at 10:25 PM

Power at Flywheel (BHP) : 160
Weight without Driver (KG) : 350
Power to Weight Ratio (BHP Per Ton) : 464.48
0 - 60 (Secs) : 3.31
0 - 100 (Secs) : 9.08
60 - 100 (Secs) : 5.76
Quarter Mile (Secs) : 11.75
Terminal Speed (MPH) : 113.79
Drag Strip Quarter Mile (Secs) : 11.65
Drag Strip Terminal Speed (MPH) : 115.20

0 - 100 (Secs) : 9.95
60 - 100 (Secs) : 6.29

It is relevant, since the algorithms that these performance estimations use is derived from manufacturers data, and they don't specify weight with driver!

Obviously the lighter the car, the greater the error is likely to be.

0-60 times are luvverly in theory, but highly unachievable in the real world. Great fun trying though

This only guessing power and weight

Power at Flywheel (BHP) : 135
Weight without Driver (KG) : 600
Power to Weight Ratio (BHP Per Ton) : 228.61
0 - 60 (Secs) : 4.95
0 - 100 (Secs) : 13.41
60 - 100 (Secs) : 8.46
Quarter Mile (Secs) : 13.41
Terminal Speed (MPH) : 100.01
Drag Strip Quarter Mile (Secs) : 13.31
Drag Strip Terminal Speed (MPH) : 101.21

iscmatt - 26/4/09 at 01:32 AM

oh and plus the aerodynamics of the 7 cars will effect the 0-100 and 60-100 times

bimbleuk - 26/4/09 at 07:03 AM

My cars been dyno'd and corner weighted but I'm absolutely positive I won't get within a second of that 0-60 time!

Power at Flywheel (BHP) : 267
Weight without Driver (KG) : 565
Power to Weight Ratio (BHP Per Ton) : 480.15
0 - 60 (Secs) : 3.28
0 - 100 (Secs) : 8.31
60 - 100 (Secs) : 5.02
Quarter Mile (Secs) : 11.62
Terminal Speed (MPH) : 118.26
Drag Strip Quarter Mile (Secs) : 11.52
Drag Strip Terminal Speed (MPH) : 119.69

Depends what tyres youre using, road (Track) temp, and wether you can put it down. Either way, these cars are still quicker than youre average Saxo or PUG.

iiyama - 26/4/09 at 09:44 AM

Power at Flywheel (BHP) : 190
Weight without Driver (KG) : 503

0 - 100 (Secs) : 9.42

daniel mason - 26/4/09 at 10:38 AM

the motaleria looks to me like it weighs far less than 480 kgs! how come their is so much weight difference between this and cloudys warner?

nitram38 - 26/4/09 at 10:47 AM

There is a lot more of it than cloudy's car!
The weight was given by the examiner after he put it on a short weighbridge (normal brake weighing not working) each axle seperately.
I need to get it weighed on a full size weighbridge to be sure.

daniel mason - 26/4/09 at 11:39 AM

it looks superb in my opinion!

I had a go this afternoon as I finally have a clutch capable of taking the power when launching. Cheap road tyes on fairly old tarmac with temps about 15 deg I managed 4.9 secs to 60mph. I tried various RPMs but basically the clutch bites too hard to slip so just overwelms the tyres so either tyre or both tyres spin up and no LSD to help either. I used a G-Force accelerometer which is very easy to use and more than accurate enough.

My old Corolla GTi also with a supecharged 4AGE also managed 4.9 secs to 60mph! Same road and accelerometer just a decade between runs

So the light weight would appear to be acting against me in this test.

scootz - 26/4/09 at 07:37 PM

Quarter mile time looks a bit optimistic to me... seen lighter / more powerful cars struggle to reach 12.4.
