Better than the dyno??
Dude - that's one of the silliest things you've said.
A random acceleration is acceptable, in a pinch, but it is not Better than a proven scientific instrument with a calibrated weatherstation and mechanical correction.

Only on the 951 board would someone say that.

7.9 sec, 100-200 km

19 psi
75 deg F
1025 feet above sea level
225/245x16

Run at a remote area of a Air Force base where the only traffic I have to worry about are deer and the base security.

Man... I need to buy a logging device, to much to keep up with at such speeds, speedo, shifting with stop watch in hand, operating the stop watch, watching the road would be much better to just drive, then go to the logger to see what you ran.

20-100 (mph) 13-14 seconds by myself, full tank of gas, 225/245's . uhhh. 50 lb subs in the back, plus an amp. and about 10 spare quarts of 20W50 in the hatch.

Why in the world would you need to carry that much spare oil?

I personally carry 2 liters of oil, and 2 liters of coolant. I take precautions after horrible experience with my 88 NA, not to mention an aftermarket air compressor, hydraulic jack, a complete tool box (for EVERYTHING i need to do in the car) and so on....

I probably added another 50+Kg to the car with what i have in the rear

I made an honest attempt to time a run but my passenger was not prepared. At about 100mph she quit being useful for data aquisition. I was a little busy myself. I have to find a better place.

OK. This is one of the more unreliable methods of measuring 1/4 mile times.

There is ONLY one way to measure them. Get your butt out on a drag strip.

Why don't tend to mention all the conditions such as temperature? Well, it seems that everyone is now stating conditions EXCEPT one of the most important: altitude.

If you are worried about accleration how the test is run can have an affect. But really, it comes down to hp to weight ratio and aero drag at high speeds.

There is a reason why 0-60 (0-100kmh), 1/4 mile, and 1km STANDING start tests are used. Some magazine have tried the "street start" reporting but that too is in accurate.

If I want to hammer it, I won't roll out at 5mph then hammer it. Hell no. Rev it up and, fry the clutch, and get a little tire spin.

If anyone doubts it power to weight ratio that matters, it is a very easy debate to win.....

lleroyb,
what were you and your lady friend doin' that she couldn't do her job and you were a "little busy"
LOL


Special,
"only somebody on the 951 board would say that"?
Maybe some of us, here, aren't part of the herd of sheep that believe that chassis dynos are Gods gift to the ultimate proof of engine power.
What's silly, is constantly submitting your car to the rollers to post dyno sheets.

David: Are your running Fuchs or phone dials? (or anything else since you're wheels are 16").

VERY nice BTW

David,

What AFB in TN? Arnold? If so, I fly in there quite a bit... and I know right where you performed your test

"OK. This is one of the more unreliable methods of measuring 1/4 mile times."

If used correctly it is MORE accurate the taking to the track.

Until gearing or aerodynamics plays a role. As the high speed roll on with car vs. bike has been discusses extensivly in here and shown many times (with my own personal experience) that cars can pull on bikes, which almost always have a higher power to weight ratio.

In a dead start situaiton, yes, you are 100% correct.
