Why no official release on Coupe performance?

FinalEd357 · Sep 20, 2005

I may have missed it, but I haven't seen any performance results from Dodge or any magazines. Should we assume everything (0-60, 1/4 mile, braking) are all exactly the same as the SRT-10? Also, do we know where the extra 10 hp comes from (filters?). I've seen releases with the car @ 510/535 hp/tq. Can someone please advise? Thanks!

Same HP, same torque, virtually the same weight. I think the numbers will be right on top of the convertible....up to 150. Then the aero advantage should be enough to increase the top speed to about 195. IMPO

There is no 'extra' HP. All SRT-10's have had 510 from the get go, they just did a new SAE certification.

Hello;

I believe there will be differences on the track.

The new Coupe is going to be more structurally rigid.... I THINK I have read about 30%. I am pretty sure that was the figure, and i am pretty sure I read it here on our VCA website in an "Official" SRT release that someone posted.

Even if the SRT-10 "Coupe" was only 15% more structurally rigid, I would think that the extra stiffness would mean quicker lap times for sure.

Drag racing, or "straight line" performance may benefit from this extra stiffness as well. Wouldn't less "flex" produce a more efficient transfer of power to the pavement?

I believe the Coupe will be faster on the track twisties, and possibly faster all-around because of the enhanced rigidity. Don't quote me on this, but I have read those rigidity numbers... I am sure of that.

Any Viper racer's want to chime in? I am looking forward to hearing your opinions as well.

Cheers!

The convertible is already very, very rigid. Far more than the previous coupe versions. We are nearing the point of diminishing returns. I don't believe that you will see much of an improvement do to more rigidity. However, at higher speeds I'd bet the slightly better aero will lead to improvement.

Dirk:

I think that the "point of diminishing returns" (save for PR/advertising) has been reached long ago.

ALL manufacturers, not cars only but also trucks, for about every new models, claim a huge % improvement in torsional rigidity compared to the previous model.
Will that mean that the "original" model was made of rubber?

What is the practical benefit of needing 40,000lbs to deflect the frame/body 1* compared to needing only 38.000lbs?

Also, I'm not sure how do that apply to cars/trucks but, in the motorcycle industry,manufactures went too far in torsional rigidity to the point that it was detrimental to handling and they "dialed back" some "flex" to the motorcycles frame/chassis.

The Dodge guys in St Louis said they had about 5 cars out to the magazines already, so the next month or two should have some good stories. The Coupe pictures from Crystal Cove I believe was the car from Car & Drive or Motor Trend.

The extra 10 HP/torque comes from a new official "net" rating system for engines. This system was started in '05 and is the new way of rating engine HP. Both the conv and the coup are up by 10 hp. By the way, the new Z06 is also up by 5hp to 505.

There is an official SRT press release. I will send it as an e-mail attachment, if I have your e-mail address.

Horsepower is exactly the same, the rating system changed:

http://www.detnews.com/2005/autosinsider/0508/17/A01-283759.htm

DaimlerChrysler is using the new SAE procedures on any model with changes in its powertrain, said spokesman Cole Quinnell. He said the company expects new ratings to be within 3 percent of the old ratings, with some going up and some going down. DaimlerChrysler is making a special effort to test high-performance models, like the Dodge Viper V-10. The Viper now tests at 510 horsepower, up from 500 in 2005.

Boy, how that structural rigidity is being pitched by DC. I'll take some more hp / tq and a good diff. Very doubtful it will have any impact on lap times as tires, suspension, power, brakes are all the same, given an equally skilled driver.

My GTS is so stiff that when you lift the right front or rear, the left front or rear comes up with it....and the SRT-10 is supposed to be stiffer....

sween · Sep 20, 2005

i HEARD that it should to be faster than expected.

SylvanSRT · Sep 20, 2005

like said above my guess is that only the top speed will show some improvement. the coupe is actually heavier than the vert.!

FinalEd357 · Sep 20, 2005

Sylvan, what is the weight of the coupe?

ViperRay · Sep 20, 2005

The coupe weighs 15 lbs more than the vert per Dan Knott, personal communication at Putnam Park.

I guess it'll be a little slower than the vert since it increases the weight to power ratio :shocked:

SylvanSRT · Sep 21, 2005

although 15 lbs is not really that significant(could be made up with only a couple of HP difference). it might depend on which wheels the coupe or vert have, the srt sidewinder wheels lighten the car by 34 lbs. top end should be greater due to less wind resistance

You forgot to wink and nudge as you typed that.

15 lbs is just a week of south beach diet away!

Mopar426 · Sep 21, 2005

I also HEARD the C6 Z06 will run 10's stock... LOL

Wishful thinking at best for both cars.

Wow! Could you imagine if a midget got there hands on a Z06. 9 second 1/4 mile bone stock I bet! Thats with light weight wheels of course.

whats weird is that R/t says the coupe is lighter. but i thought it isnt?

Why no official release on Coupe performance?
