hey guys wich is better 6.2 from the SLS or 5.5 tt

I just came across this article at inside line. They dynoed a s63 with the new 5.5 twin turbo engine with perf pack with impressive results. Then they compared the 6.2 NA of the sls vs the 5.5 L twin turbo (w perf pack.) see the graph.

I sure like my 6.2 and its barking sound especially with the back seat down, but man can you imagine a 5.5 TT in the c63??? or how about a chipped 5.5 TT... 650-700hp at the wheels? but then how would you put that power down?

so wich is better in your opinion 6.2 or 5.5 tt?

IAA-C63

On paper, the 5.5 tt certainly seems superior. With launch control, this could be a car with 0-60 well under 4.0 s. Putting this in the C63 would be crazy

I will take the 5.5TT over the SLS motor any day.
The new M157 is brutal!

How are they going to make it fit in the current W204 chassis? It looks to be a tight fit in an E-Class.

I would like to see that car putting it down on the grounf. Can you say spinning!!!

GMW

I believe anything over 600hp in a C class is just not useful in day to day driving. Plus your local gas station better sell rear tires to go with each fill up. :-)

IAA-C63

Agreed, though I think the extra torque would help in daily driving, especially when the car is already moving at decent speed (from a stop, ESP already cuts in pretty quickly in the current stock C63).

c63canada

if only you could fit some wider rear tires like some 335 series in the back that would be great. problem is that you would need to cut the rear fenders and add some sort of wide body kit.

GMW

It depends....if you have a tune with about 530hp, believe me there is more than enough torque for daily driving!! I'm hoping the next AMG C has an option for 4wd if we can tune the engine to over 600hp!

c63canada

the next bmw m5 is supposed to have 4wd available in the future. a c63 with 4wd would be awesome. plus more usefull in winter.

Let see how the trans hold's up on the 5.5TT, yesterday i was at the driving academy and spoke with a very important person from AMG and he said the MCT trans can handle up to 1000NM thats about 740TQ and to the wheels thats looks like it already maxed. (740tq=607 rwtq)

Duh, winning!

GMW

...and in rain too! I drove a new G55 last week and the full throttle take off from standstill was excellant thanks to the 4WD though it slowed down, relatively, as speed picked up. As I drove it I could see the usefulness of 4wd in quick take offs. I can never put my foot down from standstill in the C63 for fear of ESP cutting the power or just smoking the tire with little forward movement. :-) However at highway speeds, the C63 just rules! Need an autobahn!

c63canada

A C 350 4 matic probably smokes a c63 in the rain. but spinning your rear tires ang getting your rear end sideways is always entertaning. Unfortunately it also means more $$$ for tires.

GMW

....and that is the problem I like both worlds for different purposes. I guess ideally it would be best to have both a C63 and G55! Problem solved

Ive aready test drove a clk63 5.5 amg and it was pretty awesome. the power was not brutal at all. it was probably the smoothest power delivery that i could possibly imagine. sure, it was fast.....it just didnt feel fast. the 6.2 seemed to have alot more hit to it.

I wish i would have had a little more time in the 5.5 but its kind of a toss up. they are both fast, it just depends on personal preference. I personally like the 6.2's brutality better but the 5.5 is going to be very easy to modify because of the turbos. you could easily make the 5.5 one of the most brutal engines on the road!!!

Vegas_AMG

I can't imagine the 5.5 sounding like the 6.2. Turbos just don't make a deep growl like N/A engines produce.

c63canada

gt3 exhaust so much better than a 911 turbo even if the turbo is faster in staight line.

If you heard the newest pagani with the turbo AMG v12 compared to the Zonda NA AMG v12 there is no comparison. The NA screams while the turbo engine well...sounds good. Pretty much like the new Mc Laren V8 turbo.



I just wonder how much more the 5.5 tt weighs compared to the 6.2. I would guess the cylinder walls are thicker because of the boost plus you got the 2 turbos, intercolers and additional piping. So I guess It just has to weigh 40 to 50 pounds more.

Now all the weight goes on the front axle not ideal for handling and weight distribution.

You have to wonder why they didn't put the 5.5 tt in the SLS?


Would a 5.5 tt SLS have been faster AROUND A TRACK than a 6.2 SLS ?

DuaneC63

Having forced induction is a thrill and it's easy to mod. But you have to flog them a bit to make them work like a larger displacement motor as a daily driver. My C63 has the grunt all the time. My 966TT needs the revs kept up to have the same instant punch. As far as sound, a GT3RS sounds better than a turbo. So I'm guessing it will be the same for the 5.5 compared to the 6.3.

jacob502

a supercharged 6.3 would murder a 5.5 TT :-)

Jycke

I doubt the 5.5 in the CLK can be compared to the M157.
I would too take the 5.5 TT, but we won't see that one in the C-class, with the exception of the BS perhaps. Madness

Jycke

And Jacob502, sweet cars

looney100

You raise an interesting point. Even though the dyno chart posted shows the TT making more torque throughout the power band, those numbers are obviously at WOT. I would imagine that under part throttle a NA would respond much better.

Kaiba

I've owned a GT3 RS and now own the new 997 turbo with pdk.
Man , you should listen a turbo at WOT with Sport+ enabled and then edit your post
I agree that at idle and low rpm the sound is just like any other car

I wonder how the new GT3 RS 4.0 sounds

RJC

I've read somewhere it was sublime
