I tried that today, solely based on what you wrote. And it certainly did push me firmly into the seat, but I did notice a sizeable delay in throttle response from tip-in...

 

Are you running stock air filters? A set of k&n's and a passenger side intake tube to replace your drivers side will help that throttle response.

 

the truth

 

Starting in 2nd gear as opposed to drive or 3rd will pull harder for sure. Modded E55 will pull hard even from 30 MPH roll. I manually drop mine to 2nd at 70 MPH for harder pulls too. I leave it in drive of course. If you have the car in drive on a roll you have tp wait for the trans to downshift which slows you down. Yes it feels like it hits harder because of the sudden change in RPM but trust me it pulls harder quicker if you are already in 2nd gear. Dont believe it do some 50-100 runs both ways and it will become obvious to you.

Here is a 2nd gear pull from 45 MPH up a steep hill against my friends Supercharged 6.0 GTO which is no slouch. Even hit and watch how fast I pass him and pull int his lane.

 

I went out this morning to try a quick 2nd gear 40mph which is at 3000rpm and I gave it a quick blip and it just spins the tires which I'm sure the traction control interrupts the fun. I also did a 2nd gear 35mph quick blip and of it still spins the tires but it pulls harder. Just my experience. It may be time for some Michelin PSS for better traction.

 

I wouldn't expect much traction from your super beast! PSS will help a lot. They are worth the money. They don't smoke up like cheaper tires thats for sure. But, they hook and last pretty long too.

 

I heard they hook up pretty well and being that I don't drive my car that much (321 miles last year) they last me awhile.

 

Fwiw, I run PSS and everywhere I fried the tires (stock), it just shyts and gits now.

 

You need tire mod for sure my friend That is how my old Hankooks were. PSS solve that problem very well. I dropped from 4.6 0-60s to 3.6-3.8s all day long on these PSS even with 5K hard miles on them. Transforms the car. R compound is what I am getting next. Supposed to be even more amazing in both handling and straight line.

 

That's me and the only thing false is your statement above because C63s DO trap 125+ with long tubes and a tune... there are more than a handful of them on the forum, just check the C63 timeslip thread. The top end on the C63s are simply better than the E55, plain and simple. An E55 needs a good bit of mods to trap 125+, the C63s pretty much need long tubes, a nice tune, good weather, and good track prep.

 

Off topic, but why don't w211 E63s respond as well with the same mods?

 

From my understanding, although they have the same engine, to keep the lineup competitive the C63 is detuned so most of the large "hp gains" are actually just bringing the engine back to where it should be, and then some

 

Both cars benefit from good tune, long tube headers, good weather, and good track prep… NA 63's have monster top end especially past 130mph, they seem to really shine up top like the M5s But, down low in daily street conditions, light to light and up to 130mph. V8 Kompressor has advantage.

Both engines have their pros and cons. Both are great in their own ways.

 

That makes sense. But, the highest E63 trap speed on Dragtimes is only 120mph. Nowhere near the 125+ of the c63.

I understand there's a weight difference, but still...

 

400lbs or so easily accounts for that difference in trap, I'd say.
