........Ok, I am GOING to turbo my W210 E55. If the car disintegrates, so be it. I was advised to use single turbo, but on this forum there is a lot of conversation about twin turbos. Since you can make the same HP with a single turbo, what exactly is the advantage of double turbo's?

Ted

Cylinder Head

iTrader: (1)

Big singles tend to work better on engines with one cylinder bank, because all of the air is flowing through one manifold into one big turbo. Two cylinder banks on either side of the engine makes plumbing two relatively smaller turbos a bit easier. I'd go for two turbos on a V8 every time. Think about it, if you put a big single to one side of your V8, the piping for the other side is going to be longer than the piping on the near side, causing all kinds of boost issues.

I tried my best to get this to happen on my car, but the shops were kind of reluctant to take it on. If you want I can share with you as much info as I was able to gather. GOOD LUCK!!!

Ghostrider

I was thinking the same thing, by using a shorty style header type exhaust manifold (EM) to attach the turbos to, instead of merging the two pipes that come off of each EM to install a single turbo at that point.

Single turbo's lag is much more noticeable. A goodexample is with the turbo diesels. Drive a BMW 530d and then the twin turbo 535d (same 3liter engine) back to back. The 530d seems nice but the 535d is in a different league. It uses a small turbo to handle lown rpm's and then the big turbo kicks in hiher up. Twin turbos's are what make the 911 Turbo such a great everday proposition. Drive a heavily boosted Evo and you'll see exactly why one big turbo is just not that great of an idea. You'll end up with very peaky output using one turbo and with an automatic it'd be even mopre noticeable.

Well, we should finally see what the AMG tranny can handle.

Interesting if you get tranny limp mode the 65 guys get.

Take it to um Ted!!!

Schiznick

So Ted, when are you going to buy my SL65 and start tuning that? I will even throw in a slightly used set of rims and drag radials

twin turbo ... much simpler install and you can locate them more or less where the primary cat canister is. Should have enuf space and could bolt straight onto a shorty header like the evosport or renntech.

The mechanicals will be easy ... the ECU well - you need some guy to tackle that for you ... thats going to be the toughest part.

Whats comperssion on motor ? Might need to fit shorter con rods to get compression more inline depending on what type of boost you going to run... It aint gonna be easy but should be loads of fun seeing that blow by a K4 W211 K4.... ??? Well will it or wont it ?

Good luck!!!

...........Don't sell your SL65. You just ran 11.5 bone stock. A W210 E55 is a much less expensive car to rip to shreads. I can only imagine how much it will cost to buy an SL65 engine if I blow it to bits..........knowing me, I probably will.


..........I am told that if this works, getting to the 65 power and torque values will be a worst case scenario. That much higher power and torque numbers are expected. I have learned that the torque limit on the 5speed transmissions is around 900LBft. What I don't know is if this limit is mechanical or if it is software limited at the transmission control module. More importantly, the mechanical limit could be 900LBft but the software limit might be somewhere lower than that. This is what I won't like to happen. I am unable to confirm that this is or is not the case. Anyone know?

..........Engine is being taken out of the car as we speak for reinforcements. Unfortunately, the project will take a while. Upto 6months I am told, because everything will have to be custom fabricated since no pre-made kits exist.

........regarding twin vs single turbo's. I have learned that generally(not always) twin turbos reduce turbo lag, and that the pipping is actually easier on engines with two cylinder banks. Single turbos are simpler and easier to trouble shoot. The best option is sequentil twin turbos but it is a big headache to get the kinks worked out in an aftermarket application. Finally space contraints more so than any other reason drive the use of single vs twin turbos.

I'm probably not with the popular opinion on this one. I would go single to keep it simpler. The "vee" configuration can be overcome easily with a crossover or merge pipe, and the extra space can be utilized by the intercooler circuit.

I would love to see a Squires-type rear mount on a W210.

EDIT: You might want to contact Turbonetics.

Ted Baldwin

.............thanks for your response. I am using turbonetics. I tennd to agree with you regarding the use of single turbo. The turbo lag issue is important to me since I want this to be a daily driver. We shall see.

Too much is never enough. Who's handling the project?

BenzoBoi

Best of luck!!!

JamE55

Ted,

After said and done what figures/numbers are you looking at? Also how much is this project going to cost if you don't mind me asking?

Ted Baldwin

..............hoping for 1000crank HP. Not trying to be coy, but I am not sure about cost since everthing is to be custom fabricated. I am ware of such big projects like Sleestack's that did not go far. Lets just say that, if it is not impossible to do this, IT WILL BE DONE!

...........MBS motors are handling the project. I have a long and very positive relationship with them.

Ted

JamE55

That would definitely be something to see. I've been offered a project like that but passed on it just because of how long the project will take and ofcourse the cost. Good luck!

gujupimpster89@

wow im actually excited to see the results of this project, it would be a sick car well good luck with ur project

Ghostrider

That was the conclusion of my findings.

Vic55

I totally understand with the one year it has taken for you to get your carbon fiber done

JamE55

Glad you understood.

newton22

Whoa, I was reading this thread thinking "nice, nice, turbo 210, that guy is probably shooting for the 500 hp club" until I read 1000.

Dayyuum.

Ted Baldwin

..........I already have close to 600crank HP with the current Kleemann S8 configuration. So it wouldn't make sense to aim for 500crank HP. Our engines can take the boost. The problem is with engine management software.

Ted

newton22

My mistake, I didn't realize you had a heavily modified 210.

Ted Baldwin

........no problem. The s/c is going out to be replaced by turbos.

Ted

Fast55

Ted, say it ain't so!!! You already have one of the baddest 210's ever. Why would you butch this car???? Not sure of your budget, but wouldn't it make sense to find another W210 to use as a test mule???
