e55 amg underated factory figures?

+1, in a perfect world we could get enough cars together on the same day, same dyno, same track so we could limit the external factors that affect dyno and passes at the track. I still believe that most of these vehicles make about the same power, but there are a handful that make significantly more or less power.

[E55Bullet]

another factor is that some of our cars make more or less horsepower BUT these same cars may make more or less torque. So in the end they end up running the same 1/4 times. I know my car was low on HP, but extremely high in TRQ.

Mine made 432/473 bone stock '05 E55 on a dyno dynamics.. first pull was heat soaked (419/468) and 2nd pull was after an hour cool down..

I think 119.22 is about as close as I'm going to get to 120 and still have a respectable time. That night of the 119, it was my worst run 12.3@119.22 The stars would have to be in order for me to do it again.

I was under the impression that any resulting differences in output between the two models was due to exhaust back-pressure...

[Wryfox]

The diff between an E and SL is the exhaust and intake. You can fix the intake easily for $20, the exhaust just takes $. Remember guys, 469 vs 493 is 24hp, diff is only 5%. some models rated 507 but due to 80mmTB vs 74. So basically what is different between all models? Intake snorkels, TB, and exhaust. Very reasonable to explain diff in HP ratings.

Except that in the 55 series there really is no difference...they all have 490+ BHP.

[Wryfox]

Was talking about 55s in the different models. There ARE differences, just doesn't amount to much. They are all underated, which is the german way.

I saw an add for K&N for a Charger and the stock rear wheel HP on the graph was 292 from a 425hp crank rated motor. That's almost 30% loss, or the engine just doesn't make the rated juice.

What does the intake tube do compared to the stock E55 tube?

[CharlyE500]

How about E63 507Hp ? also underated ?

Nothing, don't bother

Nope. That number is just about right, maybe even a little optimistic.

come on ! r u telling me that 55k is about the same power as 63NA ?
it cant be right.... E63 can make 4.0 sec 0-60 and e55 only 4.5 sec

[guysandiego]

faster 0-60 time is the result of better launch control and suspension... If you dont think the power is the same -- look at the top speeds without limiter... or 0-150mph.... Also, I think the E63 is 200lbs lighter

This is ALL incorrect.

First, he E63 is not 200lbs lighter. Second, E63 has a slight advantage in top speed due to having 7-speeds rather than 5.

Third, the faster 0-60 time is due to the fact the 5.4K produces 516lb/ft low down and overwhelms the grip of the stock tires. One has to be gentle with the throttle initially. It's not to do with suspension or launch control.

[guysandiego]

well- the newest E63 according to C&D --- has launch control and better suspension... also it was 4100-4200lbs if i remember correctly --- that is lighter than my E55 but I have pano roof

[Zod]

this has been disscussed and proven already.
they all make the same power use the search.

Which AMG line is the fastest?
55k/65 hold the records

So if I buy a set of customize rim, 295/35/18 compare to 265/35/18
I will launch better like 4 sec to 60mph ?

things the help u get better starts

• type of rubber used
• wider rubber 295
• how to apply the throttel
• the surface on the road

Yes, wider tires will help an E55 hit low 4s from 0-60.

However, the sizes above are not a match as the 295s you list would be taller. If you currently have 265/35R18s then you'll need to change to 295/30R18 or your car's stance will be like a dragster. 295/35R18 would be too big unless you were changing your front tires to match them.

Easy hoss, it's not all incorrect...the improvements on the '10 E63 launching ability does seem to provide a relative advantage and if the E55 had it we wouldn't have to develop our launching abilities 4.0 seconds is still relatively out of reach for most 55s

Thanx for the info... when my tires are up to change, i will upgrade it...
Basicaly, Front 245/40/18 Rear 295/30/18 I guess this will be the best for our car.

I assumed we were talking about the 07-09 E63 with 7G. The new 7-speed on the all new MY10 does make a difference. The rest of my corrections are 100% on though.

No problem at all.

Actually the best diameter match if you are sticking with 245s up front (which I would) would be 245/40R18 fronts and 285/35R18 rears. That would give you enough extra width to notice an appreciable improvement in grip. It would also ensure there would be no rubbing/fitment issues.

Feel free to PM if you need any more details.
