I would say a safe gain bet would be in the neighborhood of 70hp on the conservative side, with 80-85 on the high side. If you take 80% of those figures, that should be about the torque gain as well.
Still pretty solid, puts you real close to the SRT-8 and you've still got the MDS. =)

You do realize you have no warranty, having said that why mess with the internals on the engine. What about headers, Volant, and Corsa exhaust that shoud net the same hp with less cost and no engine mods. Now, with an extra 85 ft lbs torque, make sure your AAA is active as you will need a tow when you blow the fragile tranny rated at 425.

A hot cam like that is not going to give you much in extra torque. You might even loose a little torque at low and mid RPM's. The extra HP will be at the upper RPM's only.
I'm guessing:
0-12 HP gain 0-4000 RPM
40-45 HP gain RW around redline.
You really need to see some dyno's over the entire RPM range.

Very good points AWD, the torque curve may be shifted as well with less grunt off the line.

I know I read somewhere that the trannys are not as fragile as they appear, someone had said something about a german tuning company stating that they had put over 500hp and 500lb/ft torque on this same tranmission, but that MB rates their trannys on quality of shift. So that said, I don't think we'll see a terribly high failure rate on the modified ones.
Who knows though, only time will tell...

hatax i post it again and if you know someone who speaks german they can check behind me
The tranny is fine damn. One of the guys i met from bmw (currently) but he worked for MB in the past. Told me the tranny so called set maximum is due to smoothness and the MB feel and he said MB set the max at 429.068lbs he said the tranny able to take maybe twice that but it will not have that patent MB feel. So i asked what is the patent MB feel he told me to ask someone that owned more than three MB and they can tell you, I told him look i just want to take this tranny to around 500lbs of torque and he told me you will not have a problem with that and if i not looking for that feel i could go past 600, it just will not be liquidy smooth i told him i just want to be solidly fast, he laughed. He told me if i knew anyone that speaks german to call brabus and they will confirm this but u have to speak to their cust service than to a technician and he said techs there speak little english but mostly german he said the good ones anyway. The guy asked me to keep his identity private but he told just call brabus if i didnt beleave him. Someone that has the spare money on this board please test the tranny This guy definitely knows what hes talking about and he showed me his credentials hes offical
I think this is what you was talking about

Krock, II Kings has it right - air in and air out. Then, if you need more, go to the cams. I think the breathing will really unlease the 5.7 Hemi. Don't muck with chips just yet...

Thanks redman and your welcome hatax. so can everyone please stop assumeing that this wonderful tranny of ours is not able to anything over 425 please stop unless u have proof because my source is the best thing we have and if we find someone that speaks german than we probably canget even more info if someone wants to contact brabus and they have been messing with merc trannys for a long time. so EVERYONE THE TRANNY IS NOT GOING TO BLOW UP IF WE PUSH IT PAST 430!
Why isn't anyone asking the first question that popped into my mind after reading this post... WHAT CORSA EXHAUST? Corsa has not finished the exhaust for 300C... there is no 300C application listed on their site and I cnfirmed that a number of times through the e-mail with the head of their r&d dept.

I know that Corsa hasn't quite finished the exhaust for the C. I think that most of tjhe people that posted info knew that I knew that. Assuming that the Corsa exhaust will give similar Hp numbers as the Borla or Magnaflow I asked the question.I'm going to do the Corsa ehaust WHEN it comes out SLK! 
I plan on doing all my performance mods this summer when school lets out. So I have time to wait!

I appreciate the information that you've provided from your source, as the more information is the better. But stating that its NOT going to blow up without any proof is just as bad as saying it will. I wouldn't make statements like that unless I was 100% sure. By that, I believe you should have either first hand knowledge or actual documents. I would hate to be the member that has their tranny blow because you guaranteed that it wouldn't. That being said, until I have actual proof, I would not be modifying my car over the manufacturers suggested maximum of 425. Again, I am not saying your source is incorrect or that I don't appreciate your information, its just that you should want to be sure. If you are 100% sure then that is one thing, but if you are just going on what someone has told you without actual proof, then that is something totally different. I think it is better to be cautious in this situation especially when dealing with one of the major components on the car. Just my .02 and unfortunately I do not know Germanthematrixhasu said:

Now if brabus already took the tranny past 425 how is the manufacturer 425 the maximum and when did dc say the max is 425 all we now is the srt is set to 425 we dont know if it can go past 425 and we dont know if it cant but and i do say but brabus does know becasue they have done it mulitple times so you statement is a statement of fear if your scared of the tranny blowing up dont supercharge it. but a SUPERCHARGING SPECIALIST HAS DONE IT and if you speak GERMAN in which i dont you will have your first hand knowledge.jcsganga34 said:I appreciate the information that you've provided from your source, as the more information is the better.

P.S The guy worked for MB and he has seen the tranny take more than the so called alloted 425 so unless you are a MB tranny specialist thats the best thing we have so far. Secondly no one and again no one has yet to blow a tranny so whats all the fear for, if you scared of being an elitist be a regular JOE.

I'm not trying to get into a flame war about this at all. I just believe that it is irresponsible to tell people that their Tranny will not blow all on something "that a guy I know who works for MB told me". I believe that DC has stated that the MAX it can take is 425/430 at least that is what has been reported on this website for months. Until I have a dyno of a car that is over 425 and has run for say 5000-10000 miles then I am all set in modifying my car over the specs provided. Yes, some SC manufactures have got them working on the C, how many miles have they put on the car since it was SC'ed? Who is not to say that 5000 miles down the road the tranny is gone? I'm sorry I don't have enough money to be replacing tranny's out of warranty. I guess you can call me an average Joe and I am fine with that. To all those who modify their car I wish them nothing but the best of luck and no problems. I hope your "source" is correct because I'm sure within a couple of months mods will be available to put the "C" well over 425. I'm sure we'll see some blazing fast C's putting up some incredible numbers...but a what cost? I'm not willing to void my warranty at the moment anyway so for me its a mute point. Again, thanks for the information.
