Hi all, I'm new to MB world, my ride is 2003 sl55 amg I had it for a few years and now I'm planning to mod my car.
Can I get some suggestions on what to do and who has the right parts that give satisfactory results. Should things be done in order? I thought about getting a pulley and ECU work done first, is there need for new intake and exhaust if I get that done? btw I'm from Toronto

yeah why not starting with an ECU and a Pulley. After you can further improve you engine with A CF intake airbox, Headers + Exhaust, Cooling upgrade (Heat exchanger + Pump) and why not cams.

Check Renntech,Kleemann,Evosport,Speeddriven.

Chassis : You can lower the car with a Lowering Module.

Wheels : Anything you want.

Body : CF Lip for AMG bumper, Decklid spoiler are the most common mods.You can upgrade your SL55 bumper for a SL65 one.You can also order a Brabus or lorinser bodykit (more rare)

It all has to do with what your goals are for the car if i was in the search for power i would start with stage 1, a good tune, a Supercharger pulley 168-175mm, and a Johnson CM3O Intercooler pump. This should get your can into the low low 12s high 11s in the upper 117-119mph range every car is different. Then from there you have headers and throttle body which offer huge gains when added together if you want to do these two additional mods the 180mm can be beneficial but would not put a 180mm on without doing headers and throttle body just my opinion as others may feel differently.

When does the need for a bigger intercooler come?

BeltFedBob

When the OEM gives up, most likely it's already gone and you don;t know it yet.

Heat Exchanger. Upgrading the intercooler on 55k engines is difficult and expensive (Custom Top mount intercoolers, or CLK-DTM intercooler in stock location). No company offers a really working system right Now

Front mounted Heat exchanger and Intercooler pump can be easily Upgraded.

On your sl55 the stock Intercooler with an upgraded pump works very well you could also inline a e55 style front mount intercooler for two cooling sources.

can you please explain how a bigger throttlebody helps our car? isn't the supercharger the chokepoint? if it puts out X lbs of boost, that's it right?

Domsl55

As a matter of fact my intercooler pump is probably shot. At the track I couldn't break into 12's, car quits pulling strong at half way down the track. I used to run mid to high 12 everytime before.
What is a good replacement pump that can be reliable for future mods?

Modding your car all depends on what your goal is. The 55 is a great car to tune, with lots of potential.

The ECU tuning and pulley is where most start. We get requests for many different pulley sizes and match the software to the pulley, which is very important.

We lower these cars using the STAR system and/or links. Aside from improving the car's looks, it makes the handing much sharper.

We have found that the car's stock cooling system is adequate unless you are going above a 172mm pulley.

The Johnson pump is good, but the latest model OEM works well too.

Feel free to call or email with any questions.

Geo3 neat program some good stuff in there.

I don't have a mac unfortunately, but I wanted to thank everyone for the responses and suggestions. I think I wanna go ahead with the pulley and ecu setup. What is the price range for what I wanna do?

brad @ evosport

Our evo1 kit is $2495 which includes choice of 168(170)mm or 178(180)mm crank pulley (the only clean sheet design not re-using the problematic OE damper), under drive pulleys for water pump, power steering and alternator and software.

Thanks

What kinda HP/TQ are we talking about for my $2495? I'd like to see at least 75 to 100 for that kind of doh!

brad @ evosport

Power Gains1: +45HP/55 FT-LBS.

If you can find 75-100 for $2500 or less - please share it with everyone here!

thanks
Brad

Ok...thats not bad...With a heat exchanger upgrade, and headers, are we looking at another 50 hp more perhaps?
Are the short tube headers for more torque, and the long for top end freeway kind of stuff? What's recomended?

Thanks...

(I have a "wife aceptance factor" problem when it comes to mods!)

brad @ evosport

Thanks.

Power Gains: +80HP*/85 FT-LBS.* with evo2.

Add the HE and you will get it in any weather.

Shorty headers are designed to work with the cats. If you eliminate the pre-cats you will pick up another 10-20 hp (and the same or slightly less torque).

thanks

That would be a hell of a deal...... for us that would be less than our cost to produce!

CHP_H8_ME

Ok....I'll stop messing with you guys

If you wana play, you gota PAY! "How fast do you wanta go?!?"

Seriously though, from what I've been reading, you guys do one Helluva job with these cars and I appreciate all your hard/fun work

Looking foreword to using your parts/services in the hopefully near future!

Thanks for listening,
Ray

brad @ evosport

Ray,

LOL, thanks bud! Hey, no worries, I realize these things are not cheap, but you should see the amount of time/money we have invested!

thanks
