Who cares? I can't think of the last time I raced from 5 to 60mph.

 

I am only using this as a comparison of a stock car vs a modded one, mine in particular. I am not racing anyone and I think this is a fair comparison for people who don't go to drap strips that often and when the do the suck at launching and get 2.2sec 60' times like myself

 

You just need more power. Easily remedied.

I have to be careful with the gas in my AWD Eclipse in 1st gear because even if I roll into the throttle in 1st, it will break the tires free. In the rain in 2nd gear, it will break the tires free and start to fishtail if I use more than 50% throttle. And I only have a 16G turbo at 20psi or so.

 

OK..tried it your way..I put into first gear, and let it drift forward, without applying any gas...I was rolling at 900RPMs...My time went up to 6.3 secs from 5.2-5.4 from 1500RPMs

 

EVERYONE should care, b/c the 5-60mph is a VERY good indicator of the rance of usable power in a car.

If you look at the times posted earlier in this thread from the SCC mag, youll see that even though the EVO was (in a striaght line) just as fast as the porsche, s4, and m3, its 5-60 was no where close.

The 5-60 is not only an indication of how fast you go at those speeds, but an indication in general of what kind of relative acceleration you can expect in ANY gear when you just punch the gas.

The 5-60 eliminates the possibilty of any clutch antics to get better times, and shows the true ability of the engine, and not the engine combined with the drivetrain.

You probably wouldn't want to see a comparo b/w an EVO and an SRT-4 from a 5-60mph start, you wouldn't like the results.

Its the same with the STI. All that torque down low really helps, and a lack of it hurts conversely.

 

The only way you will find out about the usable power in a car is to drive it. There isn't any indicator that will tell you that.

And it definitely isn't an indicator of how the car will accelerate in any gear. If you are above the boost threshold, there is no waiting for boost whatsoever.

 

The 5-60 statistic measures general acceleration of the car, with a handicap or bonus for the amount of low end torque present. That's all.

It is not a useful statistic for measuring low-end pull, because in most cases, the majority of the 5-60 time is actually spent at high RPMs -- a high-revving high-peak-HP car like the Evo may outperform an SUV from 5-60 by a substantial margin, although the SUV has stump-pulling torque down low.

It is not a useful statistic for measuring drag race performance, because at the drag strip, your tach will probably never see anything below 2000 RPM, no matter what car you're driving -- even in a torque monster car like a Viper, you're still going to slip the clutch at about 2000 RPM.

It is not a useful statistic for measuring real world drivability for most people in most conditions. The 5-60 test is heavily dependent on the 1st gear ratio, and except for extremely slow stop-and-go traffic, most of us don't use 1st gear in normal non-aggressive driving except when starting from a dead stop.

So the 5-60 MPH time is a statistic which measures a combination of low-end torque and high-end HP, but in a way that ends up not being a good measure of either. I understand why car magazines give the statistic, and it's easy enough to measure -- and easier to get consistent results than the 0-60 MPH test -- but it really doesn't tell much about the vehicle.

 

With that all being said...anyone else get any results??

 

From June 2003 Car and Driver:

Car | 0-60 mph | 0-100 mph | 0-130 mph | 1/4-mile | 5-60mph | Power to weight ratio

Lancer Evo | 5.0 | 13.5 | 28.5 | 13.6@101 mph | 6.7 | 12.0bhp/lb
WRX STi | 4.6 | 12.4 | 24.5 | 13.2@103 mph | 5.8 | 10.0 bhp/lb

Given the power to weight, engine displacements and tranny ratios, I'd say these are relative good times.

 

I am prettysure the last metric is 12lb/hp and 10lb/hp, else we are cleared for takeoff, houston!

3100lbs of car * 12 hp/lb == 37200 hp

Which is a @$#R@#$ lot of hp

/v

 

From 5 mph revved and launched at 5500 I hit 60 faster than I can time. Somewhere in the three second range.

twin disc clutch,Buschur full three inch exaust with test pipe,safc, boost controller,MAS air pipe and cone air cleaner,upper cooler piping........yi ha

thats not the 5-60mph measurement everyone is talking about. This is from a rolling start, with no clutch drop

 

and quickly, in response to what i was saying before...it IS correct that the 5-60 is an indicator of low down torque. But low down torque is the indicator of "at will" acceleration, starting right when you mash the pedal down....

 

BWAHAHAHHA, whoops, my bad. Yeah, 12lb/hp. =P

I agree, look at the SRT-4 with it's 2.4 liter engine. Here are the times from the same magazine (yeah yeah, mag racing is gay, but it does put some things into perspective).

Car | 0-60 mph | 0-100 mph | 0-130 mph | 1/4-mile | 5-60mph | Power to weight ratio

Dodge SRT-4 | 5.6 | 14.0 | n/a | 14.1@102 mph | 5.9 | 13.6 lb/hp (if it was done with the SRT-4 at say 240 hp since we know they're under-rated, the number is 12.2 lb/hp)

Obviously comparing to the Evo, the SRT-4 has better low-down torque. However, as the trap time indicates, the Evo does catch up and eventually pass the SRT-4 (remember due to AWD it's lower trap time, if the Evo did a normal start, it's trap time would be higher).
