Happy to see you finally got it at least. Been overseas for a bit and was hoping Weistec or Speeddriven finally released it by the time I came back. Glad it happened

blackbenzz

Everything is installed. Just needs tuning now

Congrats man cant wait to see and experience the beast in person!!

STILL Waiting For Tune From Weistec

blackbenzz

Weistec says they will come tune the weekend of June 7th

Moedy

Thats great. They couldn't tune it online linked to a computer at your local dyno shop?

hami

Finally!!! Let's. Hope they get it right the first time

blackbenzz

We tried some remote files and it was not close to running properly so as we agreed prior to my purchase they will be coming here to tune it.
Wussup buddy?? Yea hopefully the car is up and running strong this weekend. It's been forever

Djmouz63

Getting closer....

GatorMB

I am pretty sure there is a special computer dongle for their tune, I inquired about it some time ago.
Go,Go,Go!!! Blackbenz 10 or bust, cant wait to see the results.

I am going back autocrossing next month what a blast, trying to juggle events with work is a B!@#.
I will share some photos of that as well.

All the Best, Gator

Unfortunately Weistec was unable to tune the car while they were here. The weekend of June 28th rcompart will fly in and switch my car over to 55k ECU to get rid of the MAF. Weistec already has tunes for E55 so it will be much easier to tune my car.

Sounds good Gator. Have fun! I'm hoping for nines in the fall/winter

betrezra

Thx bb for blazing this trail for us mass air guys who want more powa!

Def watching you work the bugs out closely, for a future round of mods.

blackbenzz

Hopefully I Can Get It Sorted And Help Others Who Plan To Go This Route

Now that you got Rudy,,you got the best, Nice move, let us know when your done , nice job, jim
ps maybe Rudy can bring a duel intake from Nneedswings, and to fit either the 3" or 3.5" throttle body,
here is mine.

Nice car, I've been following it. Rudy is flying in next weekend. I am not putting an AMG charger on my car, it's a Weistec 2.9L Whipple SC. That intake won't fit, also I already have the 82mm TB on there. Here is my old custom intake setup (flowed plenty of cold air ) that unfortunately wont fit with the Weistec

AMGSC

Ahmad,
I'm glad you are working out the kinks before my car goes under the knife with Steve. Car is arriving today from DynoComp to Weistec.

I will be their second test mule car but at least Dynocomp already figured out the MAF problem since I was running 12 psi and it was driving PERFECT before the over-wrap on the pulley caused the ball bearings inside the supercharge to break loose.

ctravis595

what'd you have to do to the stock n/a 5.5 engine to get it weistec ready?

earlier in the thread you mentioned rods and pistons but i wasn't sure what you decided on

Nachtsturm

Get those fronts to fly!

blackbenzz

The car has been rewired by rcompart and now has a 55k ECU in it. Still getting a few codes that I hope are worked out with a tune (I'm told they are due to 82mm TB). No more MAF sensor, car runs off the MAP sensor now and has electronic bypass valve instead of mechanical. Waiting for Weistec to tune it. Not waiting much longer...

Off the top of my head... Replace front timing cover, swap to 55k pulleys, custom upper radiator hose, electric fan, shift radiator forward, custom EGR blockoff plate, custom vcuum lines, etc.

I haven't done rods and pistons yet. Want to see what it can do on a stock motor first.
Hopefully!

ctravis595

Awesome! I'm looking forward to what it can do with the stock internals also

I recently did a n/a 55 swap into my cl500 and after realizing how easy it was I've become interested in building a beastly Benz, i will probably taking lots of notes from your progress

Are the codes serious or just lame o2 sensor kinda crap?

blackbenzz

My stock internals let go with my Kleemann setup after years of boost and hard driving. The rod snapped in half and windowed the block

Let me know if you need any help.

Getting an ESP/ABS light and CEL. I was told it's due to a bad left rear speed sensor so I will replace it this week. The CEL codes are for MAP sensor and idle too high. I'm told it's due to 82mm TB and tune will take care of the codes. The car also stays on like a diesel for a few seconds after I turn it off

[QUOTE=ctravis595;5697925]Awesome! I'm looking forward to what it can do with the stock internals also

I am surprised the bottom end held with stock configuration.

A stock naturally aspirated compression engine will limit the amount of boost from any other source. Hence the intake manifold holds the effects of ram tuning- A residual amount of boost caused by resonant tuned intake and exhaust manifolds- yielding in about 2-5 psi boost pending engine efficiency and fuel available @ XRPM.
Turbos and superchargers require a decreased compression ratio or custom pistons for optimizing the available induced boost. When forcing 15-20 psi into a stock bottom end configuration you are asking for trouble.
Crank preferred is forged steel, nitrided and polished
Pistons preferred are 7:0/8:0(street) forged flat tops
Connecting rods should be free floating balanced and forged.

I used Honda connecting rods in the super late model chevy race engine for strength and light weight. Plus saving a buck.
I can only imagine where to find heavy duty rods for our Benz.
Does the dealer have a racing parts program?

Nitrous is eminent for stock 1/4 mile street cars maybe.

Cheers, Gator

blackbenzz

I respectfully disagree.

First off I never ran 15-20psi. Secondly you can still run boost with higher compression just less of it. You make more power per pound of boost with higher compression. I would never run 7.0 or 8.0 c/r, thats way too low and you would have to run alot of boost. Plus it would drive like crap out of boost with no power.

As for internals, have you seen the inside of these motors? Crack forged rods, forged crank, 6 bolt mains... STOCK! The weak point is the stock hyperutectic pistons. With a good tune (critical) I think these cars can make good power on stock internals.

Mercedes isn't like Ford or Chevy where they offer upgraded crate motors or upgraded rods/pistons.

Only way to find the limit is to test it. Wish I had tuning software so I could try to tune myself and not depend on others.

GatorMB

Thanks for the heads up,
I was quoting on experience from chevy and fords built in the past on roots supercharger systems.
While 15-20 psi is high for superchargers it is moderate for diesel turbo's. just relating to non NA engines.
I am trying to learn here as well remembering 8-71 roots 8 second pro-gas rat motors as well.
Objection sustained, Im all in, go,go,go

Gator
Ps: I have studied the integrity of the motor noting cross bolt mains (ford FE) and machined counterweights, The engine is seemingly bullet proof

AMGSC

I can sense your frustration with Weistec not being available to tune your car as often as you would like but hopefully what they will learn from tuning my car at their shop can be transferred to your car as well.

We both have the same NA 55 block and other than a slightly lower compression ratio with E55 pistons and rods, the tuning should be very similar since I don't plan on running over 10psi. I am no longer looking for maximum power but just reliable and comfortable power. I also want to make sure that I pass So. Cal Smog inspection with this car.

Even with my Kleemann setup, Dynocomp was able to tune it for 12 psi and running smoothly until the bearings disintegrated due to pushing the limits of the 2 litre Autorotor.

I have taken the same path with my M3 where instead of the HPF stage 3 turbo kit I decided to go with Maximum PSI's where it will pass smog here in So. Cal.
