do you think that V was running 125 shot with no other mods btw (to reinforce engine I mean)?

Nachtsturm

I wouldn't be disappointed. You are running with what is considered to be a super car in a sedan. Viper's at any gen are no slouches.

My friend had a 97 GTS coupe, with some bolt ons it was a solid 11 second car trapping over 123mph. I am sure your friend's viper with the mods is trapping the same.

GHAZAN

it handles 100rwhp + from pulley/tune exhaust etc from the factory. LS engine is stout for nos or NA i bet

I think sometimes that everyone on this forum is deceived about, or in denial about, how fast the C63 actually is. Sure, compared to the Toyota Camry it's fast as all hell, astoundingly fast. But next to the big boys like the Viper, CTS-V, GT500, etc it is not actually all that fast. Anemic rear tires, porky curb weight, iffy transmission--these are not the makings of a truly fast car. It's almost as if the C63 is a better poser than it is a "sports car". But I'll be damned if they aren't one of the best looking sedans on the road today, and the difference in performance might not be noticeable in daily driving situations.

Merc63

Hmmmmm..

The C63 can more than hold its own against the "big boy" CTS-V. I have eaten several of those for breakfast on both the street and at the strip. Granted they were minimally modded beyond stock (exhaust, pump gas tune, etc), but then again so am I with only a tune and exhaust.

Merc63

I never understood why guys that dont even have a benz come on benz forums and post... Whats the point? No friends maybe...



I am happy to just hang with a Viper in my 4 door grocery getter, that I can comfortable drive across the country if I wanted to with my bags in the back seat.

Not to mention when the po po roll up they are all over that Viper before even looking my way. Poser indeed.

You can take the mullet out of the GM car, but you can't take the mullet out of the GM driver.

Merc63

^ LOL.

The CTS-V is a great car with huge potential. But Its very close to a C63 both with minor mods.


The viper was going to the shop for headers today, I was following in a truck and GTR pulls up.. We all merge onto the freeway and they both get into it... Viper was slowly walking on the GTR.. But it was verrryy close.

CTS-V and C63 with PP are almost identical in acceleration... not sure why you are suggesting it isn't "fast" like the big boy CTS-V. I would also not be putting other cars down about weight or transmission if I owned a CTS-V. Anemic rear tires? Yes.

I think king335i is "posing" as someone who thinks he knows something about cars.

Easily corrected.

Headers, tune and tires (R6's 255 front and 295 rear on 19 pound Forgestars) and you will leave the piggy V on a road course. If the V has pulley and tune he will heatsoak before the tires and brakes warm up.

Big Boys ???????? Gimme a break

Even Money

^how did you fit 295 tires? Grip must be insane.

Jim Brady

The Vipers puts out around 525 lb ft of torque, has steamroller rear tires, weighs at least 400lbs less and loses less power through the drive train with a manual transmission. He will put the power down better.

Torque is acceleration, hp is top end. No shame in losing to an 8 litre Viper. He's got at least 100 ft lbs of torque up on you.

Merc63

I agree.

DuaneC63

If only it were true and you could do with out rubbing all the time. Given the C63 Front Engine RWD the car need at least 315 or 335 in back to hook up and not be all tail happy in the turns. I've got 315 on the back end of a Porsche Turbo and it eats them like pretzels

Currently Selected Tire Size(s)
Size 295/30ZR18

Load Range UTQG Max LLMax Load = 1,235 lbs
Max psi = 44 psi
Treadwear: 40
Weight 24 lbs.
RimWidth 9.5-11"
Overall Diam. 25.3"

It's a lot of tire but within spec's. 17mm pads and small tire diameter provide the clearance. Can not take more than one passenger or it will rub severely.

Chocofishez

Interesting.... Are you on stock suspension? Did you have to do any bodywork to your rear fenders?

I'm completely OEM and the difference in traction going from 255 -> 275s was staggering... makes me really curious about finding ways to get more rubber on the back.

hhughes1

I have H&R springs which lowered the car but they are stiffer. This is a track only setup which will rub with people in the back seat. It is worse with a 275/35 than the 285/30 or 295/30 because the 275 is much taller. You do need 9.5 inch wheels minimum for the Hoosiers and many brands limit the 9.5 rim to 275 tires.

Even Money

Hoosiers are great tires. I'm going with their 315/30 on my next setup.

Baby Gorilla

I do believe that it is more difficult than one would think to compare the C63 and the Viper. They are both very fast, but other than that their stock forms are VERY different cars built for very different purposes. Each has its own positives and negatives when compared with the other, but each is the best (or close to the best) at what it was made to do.

My C63 is, in my opinion, the BEST four-door sports sedan, daily driver, sleeper beast available (within my budget).

My GT500 is, in my opinion, the BEST example of raw American horsepower and torque, not a great daily driver but the most fun and best sounding car available (within my budget).

The GT500 is faster and better handling than the C63, but that's only because it is MUCH MUCH easier and MUCH cheaper to mod.

Take a look at this list: http://www.dragtimes.com/Cadillac--C...ag-Racing.html

How sad is it that a true LT/Tune Only full weight C63 such as mine is faster than every single CTS-V with full bolt-ons and pulleys?

And the few that are faster all have internal engine work/nitrous/race gas?

While I will say you are correct about the anemic rear tires I can't help but think that the rest of that statement was intended for describing the CTS-V itself....

"Porky Curb Weight" CTS-V 4300lbs vs C63 3924lbs

"Iffy Transmission" Please don't get me started on how garbage the 6L80 trans is. I have 200+ passes on my stock trans. I haven't broke it yet.

Merc63

Gotta love guys that talk **** and then disappear...

SL63AMG

I personally like both cars, but you can bolt on a 2.8 kb supercharger on the V and be done with it.
