Just for fun, I tested my 60-80mph sprint in 3rd gear. I wrapped a stopwatch onto the steering wheel, got to a flat surface on the highway, rolled at 60mph (~3800 rpms), floored it and hit the "go" button on the stopwatch, the second the mph indicated 80 I hit the "stop" button. I was getting pretty consistent 3.6 second sprints. Once the rpms get to about 4000, the car pulls very hard. I know this isn't the most accurate way to test this, but I was curious. Anyone else done this?

I usually do a 60 - 100 mph sprint in two civics and an Accord v6

Cool Test Dave. Maybe Ill try that in Mad Max and see if I get something similar. Id guess it should be about the same.

I try it in 3rd, 4th, 5th and 6th.

in 3rd it takes just a touch under 3 sec, (2.8-2.9)
in 4th it takes just over 3 sec, (3.1-3.2)
in 5th it's in the high 3's (3.5-3.7)
in 6th it's in the low 4's (4.0-4.2, engines not turning fast, and takes a while for boost to build up)

I prefer to test this way, as it eliminates the abuse my clutch takes in standing starts (slippage is bad in a high-hp heavy car where no wheelspin is possible)

BTW, nice times you're running there. Keep up the good work. Maybe someday we'll meet up for a little "grudge run"

Wow...those are quick in gear times! No way a Max will touch those without some sort of forced induction.

4 seconds to go from 60-80 in 6th gear?!?

Just for yucks, I checked Car & Driver's road test of a 2k Maxima to see what type of in gear times they achieved. Wow...what a laugher!

60-80 mph = 5.0 seconds

Top gear 50-70 mph = 9.2 seconds

They also had a 0-30 time of 2.6 seconds! That equates to about a 2.75 second 60 ft! Who was driving this thing?

And they went on to a marvelous quarter mile of 15.6@91 mph!

Hmmmm....the extra 12 hp from the Y-pipe and CAI chopped off 1.2 seconds on MadMax?!?!?!? Those car mags need to hire us to test drive their cars.

What's really strange, in 6th gear it takes just under 10 seconds from 70-90 (9.5-9.7)

you know what the problem is, they are testing out brand new cars, what is that supposed to tell you the car was just purshased why the hell would you floor a new car.

Wow...

I wish my car pulled that quickly in 3rd gear. But I can say that your speedo is inaccurate though

. I believe a *more accurate* test would be to start at a certain rpm and end at a certain rpm. Since you have a shift light you can time your 3000 or 3500-6000rpm pulls. After all 4th gen 5spds do basically a 3rd gear pull in the last 740-700ft of the 1/4. Maybe I'll time my 3rd gear from 4500-7000rpm one of these days

Cool Test . . I Tried it Tonight . . .

I did it 3 times tonight and got the following times: 3.15, 3.23, 3.20 seconds. I was pretty pleased with the results considering my maxima is an automatic, but of course the supercharger certainly helped. Later.

If you notice, the car and driver numbers are top gear acceleration. The got those roll on times leaving the car in 5th gear.

Jim-
Are you sure about those times? I was looking at a Road & Track and you're A6 is pulling harder from 60-80mph than a Ruf RGT Carrera 911. The Ruf does the run in 3.0 seconds and runs the 1/4 mile in 13.2@107mph. Are you sure your trigger finger or speedo isn't a little off

Nismo-
That's a good idea. Right a 3800 rpms my car is at 60mph. My shift light is set to come on at 5900 so technically this would be a 60-90mph run. Maybe I could get more accurate.

I did a couple runs too :)

All I can say is that I'm envious of you modded 5spd VQ's. My se-r did a 5000rpm (indicated, its more like 4800-4900rpm) to 7000rpm (when my shift light turns on) in 7.6-7.7 seconds in 3rd gear. I also timed my 60-80mph (58-76 real speed) acceleration which came up with 5.7-5.8. I also pulled on a stock 4th gen auto during a 45mph rollon

Speedo shouldn't be off one bit-->

I am talking about 3rd gear here. As you see, each higher gear makes a slight increase in time. The Porsche's test time was in what gear? I wasn't itchy with the trigger, I actually tend to be a little late with the timing. To take the turbo lag out of the equation, I would start 5 mph slower, floor the throttle, then once the speedo reaches 60, start the watch. When the speedo hits 80, stop the watch. This car makes full torque at 1850 rpms, but the DBW setup doesn't apply full torque when you open the throttle suddenly. Perhaps that's why it takes just under 10 seconds to run from 70-90. I still feel that this car puts out a bit more than 250hp, I still feel that 265-270 is more accurate.

No. The roll on 60-80 time I pulled from their "time to speed" listings. However, if they drove the car correctly, there would be a shift from 2nd to 3rd in this range at something past 60 mph. This will skew the time somewhat since the car will be accelerating harder for a bit in 2nd, but then the time required to change to 3rd gear will also be counted in thier 60-80 mph time.

The tests labelled "top gear" are indeed in 5th gear.

Has anyone tried this in second gear in an auto? I know that my Maxima can go ~84 MPH as it reaches redline in second. Haven't had the time to see how fast the 60-80 times are though, and its raining, so I won't be able to do it today.

Like MadMAx said, chances are the 911 is still in 2nd past 60mph and then the driver hits 3rd somewhere in between. Either way, you're A6 is out accelerating a Ruf 911 at full tilt. I also noticed you're not far of Motor Trends test of the C5 Z06. I think we all need to rethink this test because I KNOW a Maxima or A6 isn't gonna be remotely close to a Ruf 911 hitting low 13s

The Maxima doesn't have the hp and the A6 has a lot of drivetrain drag to overcome.

Whazzuuuppp!!!! Sorry, couldn't resist...
But just don't go telling me that my car has almost 100hp of drivetrain losses. Someone tried saying that on AW and the fights ensued.

Ill bet the losses are at least 100 hp! hahahahahahaha

In reality, the losses are probably somewhere around 25%. The AWD dynos seem to overestimate this.

The same is true of the Maxima, at least the 5th gen. 2nd is good until almost 70 mph.

It has been over 8 months and still no 60-90mph accel times?
