Hey all,

It’s been a long time since I’ve been on here, I briefly introduced myself a couple of years back. I was compelled to hop back on today and reconnect with all of you.

I’m in the process of making some changes to my SL55 for the upcoming show season here in New England, so I figured I’d show y’all what I’m working with and open the boards up to suggestions for more fun goodies I might not be aware of.

First on the list is a new set of wheels which I’m in the process of deciding on/ordering. For context, below is my current mod list and some photos. The car was originally built by Brian Fisher (FisherFast on YouTube and IG) and I've added just a few small touches since then.

Also if anyone wants to connect on Instagram you can find me at @JamesMSama as well. Let me know you’re from the forums and I’ll follow you back.

Enjoy!

James

Looks great and I’m sure it scoots. Not sure what i would do with it next. Headers and exhaust maybe.

Sweet ride! I would love to have a FisherFast SL. That guy is awesome.
The mods you have are perfect. If that was mine, I'm not sure I would add anymore upgrades. You've got enough power, a great sound system and exterior/interior upgrades. I don't know what else you can do other than drive it and show it off. I have the same color with the carbon fiber spoilers also. What brand of additional heat exchanger is in it? I'm experiencing horrible heat soak issues. I would like to have a split cooling system and secondary HE installed in mine so any info would be great.
Good luck deciding what else to do with that beast.

Very nice James. Beautiful car, what year is your 55?

I too am a fan of Brian Fisher's work, such a perfectionist. Are you still in touch with him? I'd love to hear about his long term results of testing the 77mm Griptec supercharger pulley.

I second the guidance of wrightbenz, long tube headers from MBH are the logical next step.Should put you well over 500 whp and provide a scream at WOT letting all around you know there's a beast in their midst.

I'm a little surprised by the relatively low dyno numbers given your mods. Some "load" dyno's such as Mustang read low relative to "chasis" dyno't like DynoJet because they measure power under different circumstances. Was a "load" dyno use for your measurements? Just for compairison, my 2008 totally stock 55 read 445whp and 503lb ft TQ on a DynoJet.

Who made the "Lower Lip" and have ya run into anything with it?

hyperion667

Looks nice but damn I hate decals. Keep it clean!

JamesMSama

Thanks all! I'll do my best to answer whatever I can:

@wrightbenz it moves quite good, I've had traction control come on around 60mph...headers and a full catless exhaust are next, and probably last, on the performance list!

@03sl55amgmjd I agree his builds are fantastic! I appreciate the kind words - I honestly am not sure about the brand of the heat exchanger, I will have to ask Brian and see what he says. I've only experienced heatsoak once or twice, I'll see what info I can get from Brian, but I know he custom fabs all of the work himself.

@smithwn55 Thank you! It's a 2005, it's just about to turn 49k miles, it had 37k when I purchased it and I believe around 33 when Brian first sold it. We do text now and then so I could reach out with some questions.

Interesting about your dyno numbers. This is the actual dyno video of the car: , Brian has also indicated to me that he keeps the tunes relatively moderate because he builds the cars to sell them and therefore keeps safety as a priority. As I further modify the car I'll get a bit more aggressive.

@6444johnf this seems to be the same lip in terms of appearance, it was already on the car when I purchased it so unfortunately I'm not sure where it was ordered from: https://www.ebay.com/itm/03-05-Merce...-/321939870622

@hyperion667 to each their own! I put some of these on specifically for a rally and just left them, the big AMG logo has sort of become a trademark of mine in the area because I had a similar one on my CLS55 as well.

Thanks again for all the feedback!

I’m very interested in what bulbs you put in the car. I’m having trouble with my ballast now and I want to change my bulbs. What do you recommend ?

Thanks for the information

Yes please ask Brian if he has any long term results on the Griptec SC pulley. Pros/cons versus a belt wrap kit. 77mm is my target diameter.

Tony Ryan

Lovely Car, the black roof has given me ideas too ! I think i have a

similar Rear Diffuser to your one already !

Das Geld 2

Lovely car James, I’ve found it in IG in the last as well as your limitless channel.

Enjoy it and yes fisher is amazing

JamesMSama

Awesome! What's your IG? I want to make sure I follow you back.

I've also been chatting with Brian the past few days and let him know about the questions here on the forum, hopefully he will chime in or shoot me a text with some more info for you guys!

JamesMSama

I love that diffuser @Tony Ryan ! The black roof transformed the whole car. I went with satin black, personally. I considered matte and gloss but I really like the way the satin has just enough shine to it.

Tony Ryan

Thanks James, mines a bit of a patchwork Quilt right now so the Black roof is a great idea , mines also got he Pan roof glass in smoked black so even cheaper to wrap ,lol . Love your car , great job !! Mines going a slightly different way with mods too .

SICAMG

Car looks great ! You compete in any Slipstream events at Pocono?

Tommyboy928

headers and diff lock is a must. interchiller aircon cooling would make alot hp.

IM SL55

where did you buy your CF diffuser?

Tommyboy928

Go full SL63 front , or take it all out ,Black series body kit. More fun.

Mbh headers & limited slip

Ajai Thomas
