Anybody use one in a Mini?
I'm going to re-install mine and do a few runs 0-60MPH with the 1360, then with the 1412 stroker when it goes in.
We'll see if HP triumphs over torque, or vice versa. :P

Ive got the original one from about, geez... 8 or 9 years ago... Used it in plenty of cars with pretty accurate results. We had a 400m section of "private' road marked out and was pretty spot on with speed, and it would also give the result just as we crossed the 400m mark.

Mine is an early MPH & 1/4 mile one, the newer ones are smarter I think. And expensive (I got mine s/h for nix).

Do tell us the times.

I can remember road tests saying the Clubman GT would do the 0-60 in about 11 seconds which felt really fast to me. Today they say a car is slow if it takes more than 8 seconds.

Sounds like you have the one like mine Dr. I remember it was $400 back in the day. It tells you 0-400m time, top speed and G's.

Now my iPhone can do the same thing...!

Is this the one you have Kev?

I picked one up in 2006. It was a pretty natty little device and very clever. If you get your car over a weighbridge (and include yourelf in the equation as well as a full tank) then it will calculate a very clever graph of horsepower at the wheels. Takes a little bit of getting used to this concept of a puny device calculating this, but it really is quite possible. It will measure RPM by sampling the ripple in the car's 12 volt supply and provide a ton of other information including 1/4 mile times and all that other anal retentive stuff the dragster like to collect. A useful tuning tool if you like to play with your tuning and see the results in real values.

If you don't fiddle with carbs, timing, cams, etc etc you will get pretty bored with it pretty quickly (well I did anyway...) as there's only so many times you can do your power runs up and down you favourite abandoned back strips (I used the old runways on laverton and got one a run in one direction, then a run in the opposite direction and averaged the two to account for the prevailing Point Cook gales). Good news is that if you pick it up 2nd hand from eBay, you can sell it on for the same cost you bought it for. Kind of like 'loaning' equipment.

Ive been playing around with something similar using a wii-mote and laptop, never thought to get rpm from the cigarette lighter, not that it would help in the 850.
