Picked up an E55 AMG (W211) in Feburary, and love it. Thinking about getting an S65 as a second car/project.

Trying to see how far the car can be pushed without too much effort. Was talking to Jerry at Eurocharged, he mentioned a TT V12 running Precision turbos, making 900whp on a stock motor/trans? Is that possible? I did some searching and couldn't find any info. Has anyone run larger aftermarket turbos and manifolds, ditching the factory one piece setup? Does anyone know what breaks on the V12 engines and trannies, and at what point?

Speeddriven has a 1000+ hp, 1200 tq package including bigger turbos, bigger intercoolers, rebuilt tranny to handle it, may want to call those guys. No idea on longevity or what else breaks.

Ill give them a ring

be ready to spend $$,$$$ on the build and $,$$$ on maintainence ABC, Coilpacks, etc etc

I own a german performance shop, shouldn't be too much of an issue

good deal.
i have stock turbos for sale that you can send to precision and they can modify the compressor housing

Let us know what you find out, I am also interested in what they have to say. Might determine what car I buy next haha.

M275 power limits? There are none. They are used to generate power for the anti-gravity/multi dimensional crafts we call UFOs..

jk, limitations are as much as the depths of your pockets.

Precision modified comp wheel upgrades NET 50 rwp @ best not worth removal/install $$ 900 rwp I've modded the hell out of my V12tt & unless you add nitrous for temp rice powa you'll never see anything close to 900 rwp w/out larger turbs & proper shorty headers to handle extra airflow & see 800-850 rwhp MAX for this platform Though rwtq will exceed 1000-1100+ if you build trans to handle it

I have the Speedriven Turbo/Header kit on order, should be in my Techs hands in next 8-12 wks (waiting on Custom Tial wheels) Will post Pre-Post Dynos

^Good news, can't wait to see what happens with your car. Were you finally able to get a hold of Marcin? Haha.

Speedriven1

Yes he was.

Hang on a second......before jumping to conclusions and call BS on people dig a little deeper. This was from a while ago. Its nothing close to a stock setup, gutted ABC, full cage different rear. In the end I think he ended up needing tranny upgrades, but I think its still a stock V12TT motor, just a custom build. He is a guy to ask questions and give credit to for thinking outside the box and doing most of the work himself. It may not be the path most are willing to follow, but the topic was "V12 power limits". Not to be mistaken for only upgrading stock turbo wheel.

The build you're referencing is Dynodaddy's CL600, it's utilizing 58 mm Precision Turbo's Large Top Mount IC's/ Larger Fuel INJ's/ Larger custom Manifolds/ Fuel cell/Water trunk tank/Custom Trans build/TC/custom CAI/ etc etc etc...

VS this thread asking what are the power limits w/little effort IE only utilizing Stock Motor & Trans ONLY modifying turbo's (admittedly I thought the turbo modification on 900 rwp V12tt rumor was just upgraded Precision comp wheels, not completely larger 58mm new turbo's Dynodaddy mega-build made 800-860 rwp including that combo not 900 etc)

BenzBoy12

Perfect! Can't wait to see this unfold. I want to see some 1k horsepower V12s.

Honestly 1000hp is not to difficult to get, its how much money one is willing to spend, also realizing that at that point the car is no longer daily.

RaceHorse

I don't doubt you or your proven experience, so based on it not being difficult, it seems safe to assume the motor's limits aren't really the thing to focus on. The remainder of the drivetrain handling the power becomes the weaker link. I realize you have provided tranny upgrades but what about the driveshaft, ring gear, pinion, axles? At some point under sticky tire situations the torque is bound to do some serious damage. Is this something you will be addressing with your big hp packages? Also based on these motors having so much torque what is to be expected with the 1000hp setup? Sorry if I'm a little of topic.

RaceHorse

I didn't think something like this would slip passed you. LOL I agree 860 is not 900.

Thericker

Lol I was just splitting hairs but meant real dif was his extensive mods made me exclude him from thinking he made 900 or so rwp w/modded turbs only

Thericker

I do think the gt3076 turbo kit has the potential to make 1k but so far we've only seen Marko's CL w/preliminary testing w/this kit, I think last Dyno Speedriven posted on that was 850-860+ rwp (I don't think Speedriven used ms109 or Q16 race fuels either so if that's the case a hi octane file should indeed net 1k rwp)

We'll just have to wait a bit & see what my SL can put down
