Hey, get a load of this book I got a while back.
It's a little expensive for the US, about 30 ping I'd say. But the team that sell it have some ace books http://www.veloce.co.uk/cgi-bin/veloceco/V276.html?mv_pc=113
Any way its written by dudes with letters after there name, and 99 % of it is just awesome. However, I'm gonna talk about the 1% that isn't.... just to be a kill-joy :roll:
Any way, on Page 99 theres a formulae that StrangeRanger and I discussed. He claimed it didn't work. After doing the sums, I can confirm it. It's just taken 6 months for me to get around to doing it....
The formuale for 0-60 mph in seconds is 2*W, all over T, raised by ^0.6 (the 0.6 th power). W = WEIGHT, T= lb-ft maximum.
Eg1: 69 Mustang 250 with 155 hp gross (133 net) and 235 lb-ft gross (205 lb-ft) in a 3200 pound car including its rider.
The answer is 2*3200/205 all rasie to the 0.6 th power, which is 7.88 seconds. Now anyone with a 250 Stang knows they had troble breaking 10 seconds for the 0-60, and 17 seconds for the quarter, so this is a bif over estimation.
Eg 2: 1970 2liter Pinto with virtually no emission gear and 112 lb-ft of torque in a car about 2550 pounds with its rider on board. Do the sums, you get 45.536^0.6, which is 9.89seconds. Still a bit quick for a car that never did better than 13 seconds. Over estimation again.
Eg 3: My Falcon does 260 lb-ft at the chassis dyno, allowing for 33% drive line loss. In a 3650 pound vehcile loaded up. The figures are showing a best 0-60 mph time of 2*3650/260, or 28.08, to the ^0.6 = 7.40 seconds. The best I've ever done is broken 9 seconds for the 0-60 mph, and a flat 16 for the standing quarter. Over esitmating again. What gives?
Eg 4: The new 2003 XR6 Turbo twin cam 4 liter Falcon weighs in a 3950 pounds with a driver. There is abour 321 hp net, and 332 lb-ft. Doing the sums, 2*3950/332 = 23.795, which to the ^0.6, is 6.70secs. But it does 6 seconds flat 0-60 mph with two passengers. Ok, Ford has fudged the torque rating a little, it may be higher, but the formulae is clearly pessimestic here.
Oh golly.
I've done some net impulse calculations, and they don't line up with the formulae from How to Build, Modify&Power Tune Cylinder Heads.
It's a turkey!
My advice? Buy the Ford Six Performance book instead
I just spent 30 minutes doing some editing. I keep gettin moofed...trans pacific cable has falied ping test
Changed the spelling form dosnt to doesn't. Ahhhh. Much better!!!!!
