Haven't got it on the dyno yet.

Consider scrapping all the supplied piggy back electronics that fire the two additional injectors.
Go with the "Split Second" A1C1-A2L additional injector controller.
Cost is USD $310.00
Quick to connect, 12V power, Speed signal ( green/yellow wire at the fuel pump relay) and vacuum line from the intake manifold.
You can maintain a .85 lambda ( 12.5 AFR) through the full boost RPM range and not have to retard timing.

Hoping for about 100HP+ additional which will give me about 300HP ( 250RWHP) at the flywheel on the M103 .

Boost is fixed at around .5 bar (7 lbs).

I won't be able to use the supplied electronics because I don't even have the stock ECU for my 3.2L M104 swap. The M103 computer can't run it.
I bought an Autronic SMC with harness for AU$1200 (US$900 approx.) which I want to use to run everything.
I want to get 300kW at the crank but I don't know if the supplied T2 turbos can make enough boost. I may need to upgrade to T25/T28 units.

Before you upgrade let's see how I dyno with the supplied turbos.
They are set at .5 bar, but the setting can be increased for added boost, but not recommended.

Changing the Engine/Fuel management will give you more power then the supplied TurboTechnics control as you won't be retarding the timing.

The twin 2" exhaust will give more power over stock and if you need to run a cat go to a high flow that will handle a 5.0 - 6.0 liter engine.

Twin Turbo Dyno Results

Don't be depressed.

On a Mustang load dyno we consistently pulled 195HP and 220LbFt torque.
This is a 50HP and 75LbFt torque increase over the base line pre turbo install pull.
Torque is coming in almost immediately and peaking under 4000RPM, about 800RPM lower then stock.
Pull was in a 90 degree F ambient with fans going.
Turbo boost at approx .48bar/7PSI.
AFR's set around .8 to .85 Lamba throughout the RPM range.
Still tweaking and road testing, may have to replace the new converter as it has a rattle in it.
Running 0-60 in less then six seconds.
I'm satisfied especially with the massive torque increase.

Estimate higher horsepower and torque if an inertia dyno was used to be 234 and 264, calculate to flywheel and about 280HP and 317LbFt torque.
Similar output to the old RennTech 3.6 performance package 2.

E36, M3 performance and in line with C36, C43......................

Much cheaper than the Renntech upgrade too! (US$13k plus labour from memory)
One video I'd love to see made is a race between a turbo'd 300CE, a stock 300CE and a 500E (maybe even an AMG Hammer too!). :cool:
Unfortunately I'll never be able to make such a video as no 500Es exist in Australia (that I'm aware of). A CLK55 would also make for a great race. Once my car is ready I might see if anyone on the Aussie MB forums is interested in going down to the track for a day... :idea3:

Let me know if anybody in Australia is interested in a Hammer.....I own the only right hand drive one (originally two RHD ones were produced but the other one was written off in an accident some years ago) and its coming up for sale in a couple of months.

My mechanic mentioned that he might be interested. What price are you after?

Wow....this is surely the holy grail of Hammers. :thumbsup:

Please don't hijack this thread by trying to flog your Hammer.

I'm going to start my install this week. Has anyone lowered the M104 compression by any other method than modified conrods?
I'm hoping I can machine the pistons enough to avoid shortening the rods.
Does anyone know what compression ratio Turbotechnics took the M104 to?

Vlad, PM me thanks.

The articles I posted at the start of this thread say compression was lowered to 9:1 on the M104. I assume that compression was left at the stock 9.2 for the M103. If anyone bought a TT kit for their M104 and needs shortened rods I have a set of AMG C36 rods which will drop your ratio into the 9s.

Sorry bad forum etiquette...I feel suitably chastised:o

My car is now with a new workshop that specialises in building racing engines. They're going to have another crack at taking the engine out to 3.6L before they put the twin turbo kit on.
I'm also going to try and source an LSD for the car to help put the power down.

Understand you will be featured in next month's Mercedes Enthusiast ;)

Good luck with the new installer...
I know the feeling, but if it's done correctly, you'll have one big grin on your face !!!!

Would it not be easier to replace the head gasket with a thicker one ?
