Trust me ,with the 5.5L v8, tq will not be an issue if you go turbo only. If they are sized right the car will still run like a bat outta hell all thru the rpm range. Two turbo's and a supercharger sounds like overkill in my opinon. Look at the turbocharged corvette projects for ex. And the TT vipers.
On these cars I'd say do one or the other,it's not like it's a 4 cyl car like my Talon.
Plus I thought Victor and Vadim were just gonna gut the supercharger for ease of installing a TT setup without worrying about building a whole new intake mani setup?

Just make sure the block is sleeved and you should be ok. Plus all the regulars like forged pistons, rods..blahblah.
VW has a supercharged and turbo'ed golf. Most reviews said the engine transistions were rough and the engine vibration was bad and told most viewers to upgrade to the gti. Just look up the review on the golf gt.

Latest update
I was just told that Compression check on cyclinder 4 was short 30lbs at 170lb when the norm is 200lb for a C55.
Should I continue with the Kleemann install or should I spend some more bucks to repair it while boring it out to lower the compression ratio?
I plan on adding the TT on top of the Kleemann SC so I would probably need to lower compression due to the extreme boost. How much does it typically cost to lower the compression ratio while fixing the weak compression in one shot?

I wouldn't continue with the Kleemann Twin Screw install just yet because that cylinder needs fixing. And since you need to lower your compression ratio, this may be a good time to strengthen your bottom and upgrade to the VRP 5.7L Bottom, especially since you plan on adding some serious boost later.

Do you think I can get 4 turbos on this 5.7 upgrade? If so, I will sell the Kleemann kit cheap.

4 Turbos sounds excessive, but I have no doubt the VRP 5.7L Bottom will be able to hold some serious boost. I believe the VRP Stage 3 Heads are a must as well.
I'm doing the TwinCharging Modification also. I'm first beefing up my 55 Kompressor all that I can, then I'll add twin turbos later. I should have around 850-900 hp before installing the tts.
Your car is in good hands. The 2 Vs have some awesome "VRP secrets" for my build. Stay Tuned...below are the two threads for the builds:

You got that right! It needs to be a total package. I can't say enough about VRP and how they have everything covered. I'm installing the VRP Bullet Transmission which is rated to handle 1,200lb/ft of torque and we can also upgrade it later if necessary. I have a 12 bolt rear end which should be strong enough but VRP has something for that too. I won’t really know if we have an unknown weak link until it’s all together and we start testing her out. But for now, we’re covering all of the major hurdles.

Thanks for your input Tripower.
Yeah, this is an exciting and unique build!
I know it will blow my mind the first time I nail it!! LOL

You and me both!
The Twin Turbo 5.7L V8 Kompressor is Victor's original build he had in mind for years and has invested a lot of time and effort to make it happen. Unfortunately or fortunately, he is moving on to his ultimate V12 Quad Turbo VR1000 build. Since I had the same build in mind for my 55 Kompressor, I was more than happy to install his engine build into my car. The good thing about my SL55 AMG is that it’s built beefed up in stock form to begin with and there are some areas that don’t need to be touched.
It won’t be the fastest car around, but it will be a very special and a one of a kind MB with out a doubt!
Sorry AMGSC, I don't mean to take over your thread.
I would suggest you stay on track and continue with your original twincharging build. I am! It will make your car much more unique and it will be funny when you fly by those with only twin turbos!

Right! It's a huge build which has a lot of areas that need to be addressed. But it doesn't mean it's impossible. Just take it step by step. VRP will provide these twin turbo kits for the 55 Kompressor and will soon have a complete production kit. It will be an easier modification once the first twincharging system is perfected.
Exactly! Follow Vadim’s lead cause he will ensure you get a total package and the most out of your engine build!

The VRP 5.7L bottom is the answer. It not only has a lower compression than what AMGSC currently has, but the block, crank, rods, and pistons are all beefed up and is lighter with an improved oiling system for serious hp from high boost systems.

See yeah

On todays cars my friend your wrong. In the old days they had open/closed combustion chambers. today, ALL cars have closed heads, for swirl/emisions/mileage, etc, etc. They just don't make LARGE CC heads anymore for the new toys. Which ONLY leaves dished pistons. Besides, dished pistons can lower your compression ratio by about 2 points.
See yeah
See yeah
Here's a for "old school" and milling large CC heads for higher compression!!! LOL

Sound like VRP really does cover the bases. Strengthening the bottom end is key when going with FI on an engine. No one wants an oil pan full of parts!!! LOL

Yeah, I'm impressed with VRP and what's better is that they are not raping me on pricing like the big tuners do. They're the way to go because I not only want to be able to run it hard, but I want to be able to run it hard for a long time.

The engine is currently in Canada. That's where VRP builds the 5.7L bottom and creates the stage 3 heads. It should be completed within 2-3 weeks then shipped back to their shop in CA. I'm still waiting for a "VRP Secret Mod" to be finished and shipped to CA. My build without turbos should be complete by the beginning of March. They will then add the TTs which should take another 6-8 weeks. What takes a lot of time is the tuning of the computer. VRP is currently the master at this and there is still room to learn more. They just seem to squeeze out more and more hp with every tune. It's so amazing the level they are working at. Even the Big tuners can't match them. Anyway, I'm currently deployed overseas so I'm Ok with them taking their time. Hey, you can't rush perfection anyway; Right?

I've done several one off type modifications including twin charging. If you're looking to try something different, just to be different, go for it.
However, if you're looking for a true performance car at the track than there is absolutely no advantage to quad turbos or a twin larged large displacement engine. A twin turbo system is by far the best way to go and will woop any of these one off concepts at the track. Spool is not an issue on a 5.5L engine with a BB turbo.
The additional weight, complexitiy, and parasitic loss of these systems make them far less effecient and effective than a good twin turbo system.
Here's my predicition: The quad turbo project and the twin charged project will not work as expected, will be a tuning nightmare, will not be reliable, and will not be any faster than a well built twin turbo'd vehicle. All of this for only three times the price!
Been there, done that, good luck and I hope that you have VERY deep pockets and lots and lots of patience. I have first hand experience and can promise that you're making a mistake.

Is this your first big project?

Here's a $100k Mitsubishi Evolution:
http://72.41.83.159/images/st-anima-opt.gif
It's twincharged. It's mine, and while it was a lot of fun, it did not perform any better than an Evo with Gt42r turbo. There was very little lag but this was a 2.1L destroked engine.
A 5.5L does not need any help down low. Also, I read about the new pistons, rods, and cranks. The AMG SC engine is stout and built for boost. Make sure that you know what you're spending money on.
I currently have a Porsche GT2 built by EVOMS with a built 3.8L and twin GT30r turbos. I couldn't imagine having any additional power down low. I also have a Heffner Viper with an automatic tranny (for drag racing), and it doesn't need any help down low.
I'll be the first to admit that these one off (or first of) projects are a lot of fun but I keep reading about this new tuner being some guru yet no one has posted any performance numbers. Has anyone even taken one of these cars to the track? Is it really just all talk right now?
