Yeah, yeah, you've all seen it before, put plug the numbers in again and see what it spits out.
My Golf is so low powered and heavy that it falls off the bottom of the chart, so I added some power and took some weight off. ( added 3bhp, took off 40kg)
The numbers actually seem quite accurate. Golf Ragtop - as slow as a week in the jail. Zzzzzzzzzz......
Power at Flywheel (BHP) : 104 Weight without Driver (KG) : 1110 Power to Weight Ratio (BHP Per Ton) : 95.20 0 - 60 (Secs) : 10.83 0 - 100 (Secs) : 36.93 60 - 100 (Secs) : 26.10 Quarter Mile (Secs) : 19.32 Terminal Speed (MPH) : 72.34 Drag Strip Quarter Mile (Secs) : 19.12 Drag Strip Terminal Speed (MPH) : 73.53
Then I put the numbers in for the Sylva - these are much more accurate. Very accurate actually. Woohoo !!
Power at Flywheel (BHP) : 137 Weight without Driver (KG) : 550 Power to Weight Ratio (BHP Per Ton) : 253.09 0 - 60 (Secs) : 4.58 0 - 100 (Secs) : 12.38 60 - 100 (Secs) : 7.80 Quarter Mile (Secs) : 13.05 Terminal Speed (MPH) : 102.65 Drag Strip Quarter Mile (Secs) : 12.95 Drag Strip Terminal Speed (MPH) : 103.89
Comes out a bit fast for the V8 sierra with and without nitrous. Wont let me enter a 290bhp turbo bike... But comes out slow for a stock GSXR1100W and a 750 WP Suzuki compared to measured figures. And here I have to double weight and power or it wont let me enter...
I don't believe that, not in the least, well, not when it comes to the Rangie anyway. The BMW is probably reasonably accurate but I'm not sure it's that light.
Do the figures backwards until it matches the real standing quarter then you should have a rough idea?
It wont be very accurate though because I have a bunch of real figures here (standing quarters@mph from long marston, pod, york, and dyno figures) for a bunch of vehicles I ran over the years. Some are about right. The rest are are quite fast or really slow! It doesent seem to allow for traction (lack of) other than front/rear drive, or differences in drag etc. Or the fact that you cant use full throttle for the first 1/8th on some really fast stuff... Seems ok on regular shaped relatively low powered cars.
Bugger, looks like I was bragging now, I prefer to look clueless :)
I'm looking for a bit of software for WindowsCE (my satnav) that measures quarter-mile, 0-60 etc. called "MoreRevs" or summat, or some other software if anyone knows of any ? I'm not trying to do a 0-60 dash with a stopwatch in my hand.
Never thought of that, it spins the wheels pretty easily in the lower gears, so in Real Life it's bound to be a fair bit slower...
Anyway, it's all academic at the moment, needs fixing. ;(
