Power to weight ratio calculator

____________________________________________________
The stats i put in are a realistic 180bhp for an FTO GPX @ stock weight for an auto 1210Kg

Power at Flywheel (BHP) : 180
Weight without Driver (KG) : 1210
Power to Weight Ratio (BHP Per Ton) : 151.15
0 - 60 (Secs) : 7.12
0 - 100 (Secs) : 18.91
60 - 100 (Secs) : 11.79
Quarter Mile (Secs) : 15.54
Terminal Speed (MPH) : 90.64
Drag Strip Quarter Mile (Secs) : 15.34
Drag Strip Terminal Speed (MPH) : 92.21
______________________________________________________
Again 180bhp but 1180Kg for a manual

Power at Flywheel (BHP) : 180
Weight without Driver (KG) : 1180
Power to Weight Ratio (BHP Per Ton) : 154.99
0 - 60 (Secs) : 6.97
0 - 100 (Secs) : 18.41
60 - 100 (Secs) : 11.44
Quarter Mile (Secs) : 15.39
Terminal Speed (MPH) : 91.42
Drag Strip Quarter Mile (Secs) : 15.19
Drag Strip Terminal Speed (MPH) : 93.01

So the 30kg difference gives you just under 4bhp/tonne, but drops the 0-60 by half a second.

I am not sure how much more the tip box weighs than the manual and i also know that the tip would run differently because of the torque convertor.. but i just wanted to see the bare calculations, if all that mattered was power to weight. I decided that 30kg's would make up for the difference. correct me if i am wrong?

Who has the lightest fto? or is that you Stewy?
Myfeckin, whats the weight of your 350? and what power she puttin out?

Integra Type R @ 195Bhp (factory power and weight) @ 1197Kg

Power at Flywheel (BHP) : 195
Weight without Driver (KG) : 1197
Power to Weight Ratio (BHP Per Ton) : 165.52
0 - 60 (Secs) : 6.59
0 - 100 (Secs) : 16.96
60 - 100 (Secs) : 10.37
Quarter Mile (Secs) : 15.00
Terminal Speed (MPH) : 94.04
Drag Strip Quarter Mile (Secs) : 14.80
Drag Strip Terminal Speed (MPH) : 95.68

So the factory spec of a teg type R is not far off the realistic spec of todays fto's..

I wish this thing took car specific rpm in to account....

[Myfeckin FTO]

.....Who has the lightest fto? or is that you Stewy?
Myfeckin, whats the weight of your 350? and what power she puttin out?

My old FTO weighted in or around 1100kgs when stripped. Having weighted the bits I took off and deducted from the claimed kerb weight of 1200kgs. It rolling roaded at 193.5BHP (before the speed limiter kicked in at 4th gear so it could be higher).

So actual measured figures as follows:

Power at Flywheel (BHP) : 193
Weight without Driver (KG) : 1100
Power to Weight Ratio (BHP Per Ton) : 175
0 - 60 (Secs) : 6.4 (measured at the Limerick 1/4 mile)
Quarter Mile (Secs) : 14.73

Quarter mile and 0-60 figures would have been much better with a set of R888's rather than road tyres but the above is indicative of what a small bit of weight loss and a healthy engine on an FTO will acheive - still right up there with what the fastest hot hatches can do these days.

so using your weight and recorded power i get

I hate these calculators, theyre are so many factors that can determine your power and times.

Not too far off Myfeckin's actual recorded times though...

[StewyD32]

Always nice to know something about my car.

Is mine actually the lightest around? Im sure i could shed another few kgs off her.
Might stick it on a rolling road if a get the chance and see how it fairing now, would be very interesting!

[colm_mcm]

My silver gr up at the mothers house is lighter than that, by a good bit.

[StewyD32]

How light is it?

[colm_mcm]

I'd nearly go as far as to say its the lightest in the country.

[Dragonheart]

Must be down to close to 500kg Colm at this stage is it?

[elaine]

I'd nearly go as far as to say its the lightest in the country.

LOL

[Myfeckin FTO]

I'd nearly go as far as to say its the lightest in the country.

Perhaps a photo to show the "mods" you've made to that FTO would be in order.

[colm_mcm]

I have some pics somewhere but if I can't find them I'll take some new ones and post.
Taking out aircon is for beginners, adding lightness is the name of the game.

not to bad for a 1.6 haha with an ecu remaped and actualy proper figure i should be at 180-185bhp
