Juha, i think your Injectors are "Siemens/Deka" not "Bosch" isn't..?

ZAYED,,

Ekselent

Thank you.....

No wonder when I did not have found anything online...
I found (Bosch) SL65 AMG injectors but not for SL600.

I'm gone try Siemens then..

Finally my new downpipes with race cats (200Cel) is at my car....
I made a good deal because it took 4-5 hours to change them and I paid about 250 USD for that work.

First impression is that the engine responds much faster and at same time the turbos spool up quicker. . A little more sound also but not to much.
Because I let them install them at the workshop they install ugly clamps at the wraps so I'm gone change them.
Engine certainly got more power now.May be 20-30 hp?

Here few pictures about old and new ones.

Did you wrap the whole down pipe?

Ekselent

No, I wrap it from the turbo inlet to the first corner after the cat.
I would have liked to put further but when it was not enough.

I installed my down pipes myself. I can tell you it was a major PITA. If I could have got someone to install them at that price I would have gladly paid! Mine are catless and they are pretty loud. Can easily hear the turbo's and waste gates now. With the window's up it's not too noticeable. My neighbors are not too happy with me right now. When I start up in the morning it is really loud.

Mine is loud also. I want to do some track events, a lot of which have sound restrictions so I think I will go down the electric cutout route with some small high flow mufflers in the rear section.

Ekselent

Yes... it was cheap
The biggest change happened when I installed the CAI. I can hear smal whistle and when the turbos spoling up..
When I had Scorpions the sound was higher than now.
Honestly, If I compare the CAI and Downpipes (with cats) the CAI made a greater impression on me than the cats / downpipes! I mean both did noticeable difference at power but the CAI more.

I was out in the yard when my wife came home from work...
I ask hear to start the engine because I was so dirty.
She sat in the car and start the engine....when the engine start to run she jump out from the car .... The eyes was like a big round dinner plates.... " what a hell have you done with the car".....
Startled just like hell.

Nothing.... the car is perfect now.... his opinion was I have destroyed the whole car.

Finally an answer from the company.
I have send them several e-mails and also ask what kind of product they recommend to use?
I have send them engine room pictures also... but now answers.
Only one "Rotating answer".... I'm angry. Next I'm gone call their boss also and would say a few selected words. There are sitting paying people in customer service and do nothing!!!!
They have a dealer in Germany also.... no answers!!!

Here is what "Steve" answer me from Heat shields products.

It’s a simple matter of airflow. When the air is flowing, the air will still heat up, just not as much as when the air is not flowing as much through the engine compartment. The image provides does not give us a good enough view to properly asses. Generally speaking if you shield the pipes after the intercooler it helps quite a big, you can also shield the pipes pre-intercooler. That does also seem to help a little bit.

kool ur heels & ur rig dwn w/this..

I was asking about those and the heat shield panels from the same company to try to keep the heat lower in the engine bay and the comment didn't go over well. I never understood why there wasn't more heat shielding around the exhaust on these.

Thericker

Because wrapping the exhst manifolds can actually retain too much heat as it's shuffled back into turbs

Finally answers from Heatshield products.... (Blown was right)
I have also ask if I do the CAI at silicon tube? .

We recommend our Thermaflect Sleeve ( http://www.heatshieldproducts.com/au...maflect-sleeve ) for the cold air intakes. If you have pipes, silicone hoses that change size, then we suggest you use our Thermaflect Tape ( http://www.heatshieldproducts.com/au...ermaflect-tape ). Both require minimum of 1 inch of airspace from the heat source.

I'm still waiting what they recommend under the coolers.

PS. They are very slow to respond

Ekselent

Thericker...
Can you tell us what your best time is at 1/4 mile?
We are still waiting for that info.....
All the rest of us always tell you everything openly what we are doing/made etc., but you have not yet said it?
Its not fair...

Hello...
So today finaly my first 1/4 mile run with my SL....
Best run.
-60 feet 2,321 sek
-330 feet 5,772 sek
-660 feet 8,460 sek
-1000 feet 10,750 sek
-1/4 mile 12,673 sek / speed 117,5 mph

So my BMW X6M is faaaaaaasteer than my SL600. I race them in same track and at same temparature.

I had a lot of probleems with the traction.... A lot!
Now I need better tires ....
Very disapointed.... : (

BlownV8

That's worse than stock. Something is wrong with your car. Have you dynoed it yet? http://www.caranddriver.com/reviews/...trumented-test

Here is what Car and Driver did with a stock SL600
PERFORMANCE RATINGS:
Zero to 60 mph: 3.6 sec
Zero to 100 mph: .8.6 sec
Zero to 120 mph: .11.9 sec
Street start, 5-60 mph: 4.5 sec
Standing 1/4-mile: 11.9 sec @ 120 mph

Thericker

Your Trap is the TRUE hp test & 117+mph for your mod list is horrible, you should be Trapping 125-126 mph @ the least... Guess something's wrong w/that Hot Air Intake piping & obvious those huge dog bowls wouldn't be any good w/hooking a decent 60' but still ALL your Trap speeds are junk... Betting your Tune's extremely rich beyond CAI problems..

BlownV8

Are you trying to run 20" wheels and tires on your SL? Drop down to some lightweight 18's and it will feel like you gained a bunch of power....... which you would.

BlownV8

You could also have a failing intercooler pump, air trapped in your intercooler system, poor ecu tune given your mods. Dyno test with some data logging should tell you the issue.

I now what the probleem is... Far to slippery! I need 90% more grip. I must have ESP on al the way.. : ). I run with old Camaro turbo. He had 11,5 and I lose directly from the line. He had at 60feet 1,5 sek but I catch him the last 1/8 mile and we have nearly the same top speed 117,5 mph. So honestly the power is there ... : ). My race start after the first 1/8 mile.: ). It was at airfield track.
So what kind of tires must I buy.?

Thericker

It's not your ONLY problem, in reality your Trap Speed will actually go DOWN w/better 60' though you def will run quicker just not faster. 117 mph is telling you your rigs wayyy down on hp/tq but believe what you will Prof w/your mod list you should be Trapping 125-126 mph @ the very least in the high 10's w/good DA etc.. What was the DA & Ambient track temps? You're running near Stock trap speeds..

My bud Clayton Benzorama here, ran my EXACT OE Dyno tune w/spdrvn TCU on otherwise bone STOCK SL600 @ 11.0x @ 126-127 mph on stock 18"s w/dragtires on rear, though he had big heavy 20"s up front.. IE No other perf mods... Your SL is way, way, way, down on hp... And again for stubborn ears DragTires do NOT increase Trap speeds, they make your car quicker, w/slower Traps. It will launch harder w/slightly slower overall trap. You also need to ditch the big heavy 20"s in front they're killing speed/too by adding massive drag resistance etc Unsprung weight advantages can add up to 2-4mph & drop 2-4 tenths off your final 1/4 etc..

Put snow chains on or buy some w/ice spikes lol...

Ekselent

...

Im not worried about the power.... Its there.: ). Its def. there ...100% sure about that. Everyone laught to me at my 4 races becuase they saw when my car spinn three times at 1/4 mile when I hade ESP off.... : ).
I'm really stupid when I even tried with this tires.: )

Ekselent

Yes I must dynoed the car.... The workshops are so far away from me but I must do it.
