A bit less I would have though.

Bugger, looks like I was bragging now, I prefer to look clueless

But without a dyno who knows.

Do the figures backwards until it matches the real standing quarter then
you should have a rough idea?

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.

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.

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. ;(

Years ago I used a thing called a Vericom dash computer.

http://www.vericomcomputers.com/

It relies only on a bunch of solid state accelerometers.
It was big and heavy and cost loads, it plugged into a fag lighter socket
and stuck on the screen.
This was 1988 or something.
It gave max acc G force and 0 to 60, 100, standing quarter, etc etc. And max
braking and cornering G force.
It also told you your v max.

It was accurate to a bunch of decimal places.
It was as accurate as the timing lights/beams that PB used to speed trap
bikes at bruntingthorpe and as good as the timing beams at santa pod etc.

Trevor Langfield (Highpower Nitrous) used one (his own) outside his place on
the road in doncaster to test my V8 nitrous sierra for fun to see what it
did. On remoulds.

It did (with 70 extra Nitrous and a bluprinted stock P6 10.5 to 1 V8 and 5
speed box):
0.82g on launch (better weight transfer due to **** sloppy suspension!
4.7 to 60
forgot the 100 time
and 14.1 to 1/4 mile at 110.something

Later with bigger nitrous jets it said 13.67 secs

That was almost exactly what the santa pod timing lights said too a week
later.

(And nothing like that web page said it should do!)

You can now get tiny cheap versions from places like
http://www.gtechpro.com/prod.html which are a bit micky mouse and fiddley
so use but supposedly equally accurate. WWW.TURBOBITS.CO.UK sell them, or
at least he sent me one to play with!

Extremely useful for tuning everything from suspention to engines...
