SL55/63/65/R230 AMG: It's starting..................
Just thought I'd let you know that I'll be starting my first round of engine mods on my SL55. I've been coached by who I feel ranks way up on top. (He'll be doing the work too) I'm going with a 172mm pulley setup, Kleemann headers, an 82mm TB and a tune.......should make a bit of a difference, don't you think? It's all stock now.

We have found that 172mm is the upper limit of pulley size before you start needing to seriously improve cooling.
If you think the 55 was quick before, you will be amazed by what you are doing!
Have fun and be safe!

You'll be happy on your first runs at WOT, then suicidal when she goes limp and the car feels like a Maxima without cooling mods.
You are gonna be blown away by the difference (all your mods vs stock) ...VERY SMART getting headers and TB. These babies are dying to breathe.

All the mods should be completed this up coming week. The LSD, DLM and exhaust are the major things left to do.
Hey Steve saw a sneak peak of yor exhaust and mine looks really nice. Should be able to fire that baby up tomorrow. The mad doctor was hard at work.
Now lets get to the experience..............in my words, Holy Sh*t! I think my spleen was somewhere in the front of my chest, but that all changed after I accelerated and felt the power I was not prepared for. The car, for a 4400lb machine, is absolutely an animal. The exhaust sound is amazing! I can't express it in words but it's like having the Rock n'Roll Rollercoaster in Disney strapped to your a** at all times! I'm sure many of you out there can relate to what I'm saying but this is such a great car to begin with and to exploit it's hidden power is just awesome.
Thank you Bruce for an amazing job and steering me in the right direction with the many decisions I needed to make, and to get me where I wanted to be. For those who are contimpating doing certain mods, all I can say is that I'm happy with every decision made. Just do it.................and more importantly have it done by Bruce at TTM.
I'll get some pics of the car once I get her all cleaned up and will post.
Thanks again Bruce for a job well done!
