I was surprised to see the numbers.
My plan is to do a few mods with following parts purchased already:
Weistec Heat Exchanger
Johnson 30 IC pump
Weistec Plugs
Weistec Air filters
77mm clutched supercharger pulley
Scatter shield from latemodel 21
Belt wrap kit and pulleys from Shardul
Eurocharged TCU and ECU
I'm not new to hopping up cars, but I am new to Mercedes cars.
After the baseline, I started tearing apart my car to start the install. I do have a few questions for anyone that can answer (sorry, but there is much for me to learn about the AMG55.
Does blocking the oil cooler with the Heat exchanger have much affect on the oil cooler function?
I hear that the old Bosch IC pumps were not very good. Does this include my stock 2007 IC pump or is my original an ungraded pump by this time?
I didn't get any instructions from Weistec on the HE install and can't seem to find any instructions on their site. Do I need to remove the original HE unit? Any guidance here would be helpful.
I hear that the factory MB plugs are indexed. Is this true with the Weistec plugs?
Thanks in advance...

don't waste money on that pump upgrade. the OEM 010 bosch pump is superior and you probably already have the new version. I would use both the original HE and the new one you have together. Run the water through the original first, then the new one. One step colder NGK plugs are all you need (or keep the factory range NGK) I have no clue what the wesitec plugs are. You are also likely better off keeping the OEM paper filter too. not sure what the weistec is, but more flow usually = less filtering and little to no gain.

Thanks - Yeah I found out in the W211 AMG area that the 010 bosch pump is better and that is what I have. It's staying and works fine.
Weistec is where I started because of their MB presence and stature.
I'm learning more everyday.
The car should be pretty solid by the time it goes to the dyno next time.

It's 100% stock. Who knows about the dyno, there are variations between dyno's to certain degrees I'm sure. I have never used this dyno guy before, but was recommended by someone I trust. The 2007/08 SL 55's were rated higher (510 crank) than the E55's (469 crank) and the earlier SL's (2003-2006 - 493 crank). We'll see what happens with the mods installed. I was expecting 420-440 wheel based on what I've seen with other AMG 55 motors.

Typically there is no.actual difference between what an E55 dynos and what an SL 55 dynos. There was a lengthy discussion on the topic some years back. The general concession was that the difference was marketing by MB.

07-08 SL55s came with 80mm TBs and larger injectors along with updated ECU/TCU mapping. This adds a small but noticeable amount of power.

I did the baseline dyno for my stock 05 SL55 back in February and it pulled 423 whp and 463 max torque. I was thinking it would've done a lil better for a factory 493 crank hp. Will a different pulley and exhaust give me that much more whp?

you have upgraded Bosch already on the 2007

you have a 74 mm trottle body on this older model, and not so good intercooler pump , 2006 SL55 and up have 80 mm ,same as SL600 V12 . would go crank pulley, so you get more rubber to avoid slip on the belt on compressor wheel.. i tryed this belt wrap kit, and if have little crazy driving , belt goes to hell / melting.. so now the standard belt set up, just using 1 belt wrap system pulley to have it more stable / stronger.

I'm not going too crazy with this car - once gone too far, there's no turning back - been there, done that. It's been a great car, just trying to tweek a little more out of it.
I bet you'd be
if I told you that 462 was in 5th gear (.83)!Funny - It bounced off the speed limiter approaching the upper end of the RPM's in 4th gear. Had me wondering for a minute why it wouldn't go further.

what you guys think about what my dyno guy say after first testing,, without touched the ECU yet read , 523 hp crank , stock 517 europe with 98 octan fuel.. 1 to 1,1 bar compressor pressure compare to stock 0,6 , kleemann short headers installed, KN filter, all catalysators removed, stock resonator box and exhaust all way back after specal made X pipe from uk.
180 mm crank pulley Weistec, 2 intercoolers hooked up in serie, ,split cooling from engine radiator. and still all this after this , its just 523 hp . but the trottle response and it felt like it was 70 more before ECU tuning . so what y guys think about this

airflow enought to feed a cruise ship engine
hi, was plenty airflow, industrial huge fan, bigger than i seen on any other dyno places , was blowing hard.
i also have changed the compressor ,to brand new one from Germany before dyno testing , probaly taken off a brand new factory engine.
so even if not add more fuel, is strange that numbers are so low as from 517 hp to 523 with all this changes.
