As what the title says. Without going "really" internal (pistons, crank shaft, rods etc..) can you guys pls list what other mods is available to our 55 engines. Here's a list of what most of us have done. Just wondering if there's anything else we can add.

1. Cams
2. 80mm Throttle Body
3. Headers & Downpipes
4. ECU
5. IC Pump
6. Port & Polish (has anyone done this? results?)

Anything else you guys can add?

 

Carbon fiber airbox, pulley

 

Great thread, since I want to do exactly this......"light" mods.

K&N / Green Filters
Intake tubes / replace and or heat wrap
Remove resonators

 

i doubt there's any appreciable performance gain but i'm really interested in how you like your car with the resonators removed. how much is the sound quality improved compared to any cabin drone? this seems like the easiest way to improve the tone if it's not too bad in the cabin (actually, i wouldn't mind open headers but the wife and neighbors might get a little annoyed!).

 

Actually, there are VERY slight gains in responsiveness at the low end.

The sound is the major love. I replaced mine with two straight pipes, so it is actually two mods in one. Low rumble is increased just a tad. Also, the stainless sound comes through much better, with a slight pop to the gas. For $100, it is a no brainer mod to me, especially considering how well the AMG pipes works as is. The last part I like is the dual pipes. It gives it the old V8 thud thud sound while idleing, and I love it.

Interior drone is only BARELY more. You can tune it in and out depending on hwere you put the tips. Mine are in the exact stock spot, but you could push them out for a VERY quiet ride.

DO IT DO IT!!

 

great info, MUCH appreciated. did you add a crossover to your new straight pipes?

 

No, I like the left / right sound, so I left it open. ALso, that connection can act as a resonator and i wanted max noise. It is EXTREMELY subtle.

 

Light mods would be ECU upgrade, full exhaust, and custom intakes with cone filters.

 

I was wanting to see somebody throw some cones on it and remove all that crap.

Let's see!!

 

I want to see what solution my race shop is going to come up with mine, but I should be able to by the end of this coming week.

 

James, did you run of out mods to do?

 

POST PICS!!!!

 

I'm planning on testing that on the dyno in a couple weeks when I go back. Figured a 90* piece of silicone tubing with a big K&N cone on it straight to the TB would pretty much determine how much (if any) gain there is to be had in the airbox/intake tract. I was going to test it with the hood open on the dyno just pointing straight up. Not terribly useful for daily-driving, but it should pretty effectively show what the stock airbox leaves on the table.

 

So jangy when you throwin down for the EVO package? Quit the light stuff it's bad for your health. lol
Sadly yes! LOL Unless i really go "into" the engine (bore the block, change pistons etc...)think i've pretty much maxed out the engine mod dept. Help me find other ways Ling. lol

 

It looks like I will be doing a stage 2 pretty soon, along with an LSD, and rotors. Still stuck between K2 and Evo2. Such decisions....

 

.....ok.

W210 E55
1. s/c
2.ECU
3. headers
4. custom exhaust with custom resonator to eliminate drone
5. port and polish heads
6. IC pump upgrade
7. gear ratio change to 3.06
8. smaller s/c pulley
9. custom torque converter
10. Kleemann suspension
11. Larger crankshaft pulley currently undergoing bench testing
12. GruppeM air intake
13. LSD
14. Kleemann CAMS
15. Almost forgot Evbosport underdrive pulley

Ted

 

Dude, what kind of power you putting down? What LSD?

 

...........Kleemann LSD.

...............Last dyno before Evosport underdrive pulleys and before larger crankshaft pulley was 450RWHP and 506 Rear wheel torque. This link contains the the dynograph. https://mbworld.org/forums/showthrea...project+update


Ted

 

Very nice numbers. Have you run against any W211 K2s? I'd be curious how different, if at all they are out of the dig and up at speed.

 

Give up on the mods old timer, your car is not even broken in yet. What u have on it now? 600 miles?

 

Is James' car fresh as a virgin?

 

Yeah.....just as fresh as James!......

 

You saying he's a virgin?

 

Sadly so.....

 

E270?
