looks to be a quality kit and with that increase of HP should be insane. Also loving the gif lol good job!

est total cost?

Thericker

Can you show us what it looks like from 0-3k RPMs as your graph starts @ 3k RPM's Thanks

kohjul

are you using stock header to the turbo or using a new header?

Ali_E55

price ?

SaintC63

Whoa....cost?

slownrusty

It would be cool to see the stock turbo and cast manifold next to the Weistec turbo and stainless manifold for comparo purposes.

Really nice gains.
I really thought it would have been closer to 1000hp with the larger turbo. Something like the supercharged 6.3 L gets or is that not an achievable number.
What is the most you can get on 93 oct. gas?

vdubpower

Yeah what does 91 California octane give u.

Worth the wait

You guys are my new heroes!!!!

Stunning work, keep it up.
By the time I get my 2014 E63 4matic AMG-S (there's a mouthful..lol) this should be fully sorted and readily available.

JOY!

Worth the wait

Btw will this upgrade require any trans work?
Thanks!

vdubpower

what wheels r they

Nice gains but I also had those "real" down pipes ever since I did my turbo upgrades it's not something new its available at GAD motors since April 2012

I wish it had an external wastegate. I would love to see the look on people's faces after the wastegate goes off.

I think they are using stock collector while your collector is bigger = exhuast air before turbo ( the part that have 4 holes where air is coming out from the engine ).

they only replaced headers ( after the turbo ) and to exhuast.


your setup Mohamed flows more air i think

MKB-C32

They call it downpipe not headers.

Ali_E55

OK

and the part that has the primary cats is mid pipe.

E55 RUSS

So any road number with this set up 100-200 km and 60-130 ???

What about pics of IC system ???

Dyno number are nothing with out real road test numbers...

My CLS 63 full catless exhaust was faster then Digitec 800 PS CLS with turbos and run same rolling start with Evotech e63 with turbos and headers....

otherotherbenz

i believe they are called test pipes (catless)

MKB-C32

hahaha

These are Klassen M55 SP Wheels.

There is no "collector" with this particular exhaust design. Not with our upgrades, nor anyone else on the M157 engine for that matter. Just like any other turbo system, there is an exhaust manifold (or header depending on design), turbine housing, down pipe, and mid pipe.

I believe you are referring to the manifold. There is a few good websites you can find on the net that will really educate you on what is what.

Ali_E55

Weistec call them mid pipe

Ali_E55

collector = manifold ( what i meant)

so no company made bigger exhaust maniflod in the market ?
is it because no space or it doesn't add power ?

can you share more also on the cooling additions ?
how much is it bigger than stock H/E ?

dbasons55 has 4X bigger than stock + 2013 saperation

just to for information and what is the price for your turbos + the larger " downpipe".
