So what's your Power/Weight ?

[woodman]

133hp /508kg =262bhp per ton

133hp /585kg=227bhp per ton

narrow body sei, x/flow,road going sprint car.

now approx 490kg with removal of screen ,pillars,wipers and fitting of acb 10 tyres for change to class e in wscc spints.

There seems to be a lot about 500kg ish me thinks some more work is needed on the race car

[davidgh]

For those who think Strikers are light  --  here's the awful truth.

At exactly 550kg the orange beast on the left is marginally the lightest car-engined, road-going (screen/wipers, etc.) car that Raw have put on the corner weights. With ca. 160ps of standard 1600 engine that works out at only around 290 ps/tonne  -  and that's before you handicap it with a svelte 85Kg of ballast behind the wheel.

Still fun though

Bog standard CVH

Without driver !

100bhp / 602 kgs = 166 bhp per ton

With driver, don't even bother  

Still couldn't keep it on the black stuff  

Surprised I managed to break 50 seconds

My Megabusa was :-

480Kgs on Blackbird Motorsports scales and 185BHP at the crank on our local Rolling road (so anywhere between 20BHP and 300BHP in reality)

On its own 185/0.48 = 375BHP/ton

With pie man on board 185/0.58 = 319BHP/ton

Matt

it maybe that some of the cars [inc mine] are narrow body which are significantly lighter to start with

[Blatman]

Matts race car is a narrow too....

[barney]

Does anyone have the data to the difference in weight between normal and lightweight bodywork for a narrow bodied car..

just *ahem* interested,

well winter is coming

Thanks Woodman yep as Blatman said my sprint car is an SE and not and SEW its about 540kg so a little way to go to get it down to 500kg but all I have really done is remove anything that was not required carpets boot box etc. The rest is down to spending money on lightweight stuff. Still when I think I am good enough to be able to tell the difference between a 540kg car and a 500kg car then it might be time to get my hand in my pocket.    The car is not helped by having a lump of a Vx stuck in it. A mate has an almost identical spec Zetec car and that is more than 20kg lighter than my Vx car so I already have a penalty there.

It'll float away soon if your not careful

[fordy]

Wasnt measured on ACWs scales, but has been weighed before.

120 bhp /640kg = 187.5 bhp/tonne - without me

120 / 705 = 170 bhp/tonne - with me.

Road going xflow.

Just as well im a lightweight

It would be interesting to have these figures next to our names on the timing sheet at events - makes it easier to work out if your doing well or not.

2001 SEW 1600 K with carpets, interior panels, sports seats etc:

534kg unladen

With male driver installed: 620kg.

With No.2 driver installed: CLASSIFIED  

185bhp gives:

346 bhp/tonne empty or 298 with me.

Very happy with front:rear distribution ratio of 47%:53% and cross weight percentage of 49.2%
