0-60 HOW MUCH FASTER IS THE SRT THEN A GEN II? (BOTH CARS STOCK)

[EXECMALIBU]

HAS ANYONE CLOCKED THEIR SRT FOR THE 0-60 TIMES?.. THE GEN II CARS ARE SUPPOSED TO BE 4.1 SEC..
WOULD 3.73 GEARS MAKE A GEN II FASTER 0-60??

 

[Craig 201 MPH]

NO!

 

[M. ROD]

Best I've seen:

GTS=> 3.89sec.
SRT-10=> 3.9sec.(Pre-production prototype)

 

[Craig 201 MPH]

The main resaon is that the SRT is geared to exceed 60mph in 1st gear whereas the old car would hit 57mph and with 373's you will still have to shift and getting traction will be much harder.

Of course if you have a superviper with 6,000 h.p. because the current car is crap it will beat the SRT.

For Real? I thought Gen 2s could get to 60mph in 1st gear.

From Motor Trend:

The Viper required a longish throttle lift between shifts. Fortunately for the Dodge, the 1-2 upshift occurs after 60 mph, and third's good until well past the finish(1/4 mile). In fact, its not difficult to drive a Viper using only third gear. It's got more than enough torque to start in third, 70 mph in that same gear is just 3900 rpm, and the redline doesn't come until past 120 mph!

Strange. I read in motortrend as well awhile ago that they hit 57mph, I think I also read it in chrysler published material.

However I think I recall reading that quote and it being about the SRT, it was recent wasn't it?

 

[MichaelP]

Well let's see why don't we ask one of the guys who actually OWN an SRT

 

[M. ROD]

Motor Trend, August 2000 issue;

Cover Story:
Shootout: Corvette ZO6 vs Mustang Cobra R vs Viper RT/10.

 

[J DAWG]

For what its worth, I have to shift into 2nd before 60 in my Gen II, around the 57 mph mark.

I also assume, with everything being equal, stock for stock an SRT would be a touch quicker to 60. I think DC made sure the next generation Viper was faster than the last(stock). Just makes sense.

 

[Snakester]

The SRT-10 Vipers share the same 3.07 gears and 6000RPM redline as the GenII Vipers do. So most likely they also hit redline at 57MPH. But 57MPH is VERY close to 60MPH, so maybe you actually hit the rev limiter at a couple hundred revs higher, seeing 60MPH in 1st.

I haven't hit the limiter myself, and except for the few rare folks who have broken in their motor and ran their SRT-10 hard, I'd guess that most SRT-10 Viper owners haven't either.

Regardless, the SRT-10 Viper does have more HP and torque, so potentially they are quicker than all previous stock Vipers. But I'm still waiting to see a full magazine test done with a broken-in production SRT-10 Viper.

I am hoping to see a faster than 3.9 second 0-60 run, and sub 12 second 1/4 mile times, if they can get a skilled driver behind the wheel.

-Dean.

 

[CHAD]

Don't forget the SRT has a taller rear tire (1.3"), pushing it faster with the same gearing in the tranny and rear at the same rpm. We know the Gen II will run 57mph so the SRT will run exactly 60mph at the same rpm and gearing with the taller tire.

The SRT-10 Vipers share the same 3.07 gears and 6000RPM redline as the GenII Vipers do. So most likely they also hit redline at 57MPH. But 57MPH is VERY close to 60MPH, so maybe you actually hit the rev limiter at a couple hundred revs higher, seeing
60MPH in 1st.

Motor Trend's editors got 60+ mph in 1st gear, that was achieved in a Viper RT/10. When a car's performance is being tested they avoid to hit the rev limiter, and they make more than one run.

I thought that the SRTs redline was 6100 rpm;
From Car&Driver:

The engine's redline has risen 100 rpm, to 6100 rpm, with maximum power achieved 500 rpm below that.

But who knows, after all they are the same magazines that are use to drive Echos and Civics. I rather believe you guys that DO own the cars.

AMEN TO THAT BROTHA!.

Take care, Mike.

 

[BACKNBLACK]

Isn't it fact that having a convertable you would have more drag on it slowing the 1/4 mile times, even when top is up??

 

[Snakester]

The SRT-10 Viper is supposed to have a much lower drag coefficient than the R/T10, and comparable to the GTS (obviously with the top up). Testing mules had supposedly ran as fast as 212MPH, which would have required MUCH more power if it had close to the drag of the R/T10. And yet the R/T10 has the fastest magazine 1/4 mile time for any Viper (at 11.77/118MPH) despite having comparable power to the GTS and far less than the SRT-10, and having much worse aerodynamics.

-Dean.

 

[M. ROD]

GTSs have a cd of 0.35. Anyone knows the SRTs cd(top up)?

Testing mules had supposedly ran as fast as 212MPH.

I'll be very happy if I see some mag getting 200mph out of the SRT. 212mph, I will fall from my chair . The more aerodynamic(I think, not sure), more powerfull(580hp) Lambos top speed is around 208mph-210mph(or so I've read). What was the HP figures of these mules? Whats the real HP number for the SRT 520hp-540hphp?

I think the Gearing is such that it could go 212 MPH @ 5900 RPM, but I do not think the stock SRT has near enough power to go 212 MPH here is a chart:

As you can see, here is a chart that shows how much RWHP you need to go a certain MPH given a certain rear end gear, trans ratio, drag coefficient and frontal area. I think I remember a posted CD for the SRT of .32, I know the Corvette has a frontal area of 21.3 sq ft. I have been generous here giving the SRT a .31 drag coefficient and a frontal area of only 21 sq ft. Here you see that with these #'s 447 RWHP is needed to go 201 MPH and 518 RWHP would be needed to go 212 MPH!

[M. ROD]

, OH MEN! I've got so much to learn, thanks.

 

[Snakester]

When I read about the 212MPH runs in testing I assumed that the particular test car had much more than the 500HP rating, but the key here is that as drag goes up, it takes MUCH more power to attain high speeds (as seen by the numbers above).
And it would have taken a huge amount of HP to pull 212MPH in say an R/T10 with a 0.50 cd.

I expect that the SRT-10's top speed will be somewhere between 190 and 200MPH, which is awesome for any car, and moreso for a convertible.

But at lower 1/4 mile speeds, drag is not as much of a factor (as long as you have the top up.)

And having 3.73s is not always an advantage in getting faster 1/4 mile times because you have a much greater chance of wheelspin, possibly making the car actually slower than stock gearing unless you have slicks, or hook up perfectly.

-Dean.

 

[Craig 201 MPH]

I can easily see it attaining 200+

6th gear is supposed to be much more usable now plus it has better aerodynamics.

The fastest ragazine top speed for a GTS was 192MPH I think the new car can easily pull 8 mph given the same room to do it in.

 

[MichaelP]

Ok come on this is the SRT forum. Does any one with an SRT actually post in this section or just us wanna bes.

Some rich [******] with an SRT can you just tell us if you can go up to 60 MPH in first gear.

 

[GR8_ASP]

Well I can speak for the northern SRT owners. Just not enough good warm weather to get past the 500 mile break-in period. 272 miles to date on mine and no driving this week due to freezing temperatures.

I recall the drag coefficient being stated elsewhere and it was not as good as the GTS. Frontal area was slightly different as well. Doubtful you will see above 190 stock.

Regarding 6th gear. It may be more usable but will not be the top speed gear.

 

[SylvanSRT]

Sure it is I turned 870 miles today, I picked up my car Jan. 14th at CAAP.

 

[Y2K5SRT]

Speaking on behalf of the poor ************* ***** SRT owners, I can tell you on good authority that it cuts out at approximately 59.7 mph in first gear. And no, I won't do it again.

[jwwiii]

From the "heartland oflanded gentry" I will say this;

My SRT now has 1,534 miles on the ODO (yep, I had my butler check it to make sure)) and I have calibrated my G-Tech "Competition Pro" to my best abilities and research... actually, my butler did that for me because it was my spa time! Now that I have qualified my bad self, I will tell you my findings.

My SRT is making repeated 0-60 runs (on scoped out, public highways, as I OWN the local Militia) of 4.0 seconds. It is just stock, and I am a rookie just having fun.

Yes, the SRT does get to around 60mph when you gotta shift to 2nd. I am not interested in blowing it up; but the tires are spinning, trees are passing at warp speed, and each run is a learning experience. My butler just quit because he can't record and crunch the numbers fast enough. I got pissed at him because of his mathematical incompetance... crap, I even missed my pedicure because he couldn't balance my checkbook at the same time!

Heck, if I can run "unofficial" 4 sec 0-60 while taking my butler along (together, we are 600 pounds or so) then surely someone will crack a 3.7 or 3.8 on the "slim-fast" plan and on a flat track.

Seriously,

Jim
