From GotTheBenz:
This thread invites ONLY those in-the-know (NOT those with opinions,
no clue or slander) to reveal their results and proof of their
Stage 2 and Stage 3 mods from Speedriven.
I posted this thread to get FACTS. And yes, I've left two emails and
one phone call to Marcin---no response. So here I am:
Thank you,

Its a very expensive upgrade so I don't think too many people have had this done on their cars. Goodluck with getting the info. Its a very interesting topic.

my post here. My bad.
Good points R.K. Personally, I think "expensive" is all relative.
What is today "expensive" for me to upgrade a V12--was just lunch
for me, just a couple years ago.

I believe many can relate with that
![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
Yet, I've been researching performance upgrades for a year. And it
seems that for Stage 2 and 3 mods---Speedriven wins in value.
But, it'll be great to have Speedriven customers chime in

Flash: I was wrong. Marcin did email me back about 24 hrs prior to
my post here. My bad.

Bang for buck the upgrade is very expensive. You get new injectors, intercoolers, turbo's etc.. You have maybe $10000 in parts and the rest is gravy and labor to install it.

Speedriven's Stage 2 (claimed 800BHP) is retail $5,000 parts, about $1k labor.
Their Stage 3 (1,200BHP) is just under $30k parts and labor.
$30K is almost as much as I use to spend on rims..., nor
would a 1200BHP Benz be my fastest ever owned.
So for me, I think $30k Stage 3 is not that expensive. And based on my research----Best Bang for Buck!!...if true, goes to Speedriven.
IF. Thus this thread for validation or...

Here is the first one posted on the forum. Peak power is very narrow and falls quickly after 4800 RPM. http://imageshack.us/a/img687/360/speedrivenstage3.jpg
Here is another that looks really good. Not sure what was going on in the first one.

those "in-the-know" regarding their Speedriven V12's.
I'm not here to brag about my past cars. Hopefully my last post
didn't sound "braggy", as that was not the intent.
For a moment, I was actually unconsciously, sadly lamenting...
![off topic](https://mbworld.org/forums/images/smilies/ot.gif)
But...here's some hints.
Like the SL6's which came factory with twin turbos---so did this one.
Yet, this one doesn't have hook-up problems like modified SL6's.
It weighed about 2425 lbs--stock. Was relatively easy to modify
to 1,000bhp, and was made by folks who ate lots of pasta.

Anyways, I'm sad again---thanks.

Now back to Speedriven V12's

^^You can get that kind of power without doing the turbo's. Just throw a racegas tune in there and throw some timing into it.

CL65 AMG , white S550 Sport w/ white Giovanna 22s, wild custom chopper
Add a built tranny to that list too, right? Also, the exhaust manifolds to house the larger turbos and down pipes are new & custom fabbed. I don't have this setup, but when I get bored of Marcin's intercooler package, my CL will go from Cali to Illiois.
