i am reading this correct that in the second run, just changing the airbox and MAF netted about +150hp to the wheels from the first stock run? if so , thats fricken sick! or is this partially due to the fact that the c63 is considered de-tuned in stock form? and then another +130hp from that to wiestec? I need to get a c63

Pretty sure 2nd run was with Weistec stage 1 and 3rd run was with weistec stage 2 which has more boost and different tune for addition of exhaust.

I figured I only remembered because they let me play with a set at Evosport a while ago... Lots of drooling...

I would think Long Tubes, an airbox (not Carbonio), a pulley, Weistec, and tune would easily push 600whp...Of course you just dropped north of $25K, but what's the board motto...You gotta pay to play.!! No, it will not be me...haha

Anyone have an update from recent experience?

...are you thinking of doing it? I'm surprised no one has done it on this forum on their W211 E63s. Shouldn't they run 10s just like the E55s if they're making over 620whp? I'm really curious because I drove a 63 and something about it made me like my 55 less, not much but just a little. There's something "tighter" about it. I'm thinking why start modding my 55 when it's getting pretty old and with all those cooling issues and what not. I'm thinking if I sell now and get a 63 and slap on a Weistec, even if it's 15k just for the kit, I could potentially have a 10s W211 while also being a newer year model and lower mileage. Why is the torque lower on the blown 63s? It's a bigger engine and their whp is higher than the highest of the 55s..... plus how are the gearboxes in the C63s holding with that much power, I thought the 7 spds couldn't take it.....

I also forgot to mention the insane sound of the 63, it's INTOXICATING. I wish we could make the 55 sound like that

CharlyE500

The E63 interior also feel and looks better. However, selling your 55 and getting 63 will need to dump other $8K easy (dont forget tax) Plus, $15K on the SC kit and $2K installation so total cost $25K. For 55k platform you can do 10's with $10k

A weistec 7spd e63 will walk a stage 3 so hard it will be embarrassing.

W109 W211 6.2L

Thank you for the honest words. Agreed

I wouldn't be so sure. How well will the 7 speed transmission in the E63 work with all the new low-end torque? Will the torque limiters in the TCU software be a limiting factor?

Also, it seems that the E55 still makes more power down lower in the RPM range than the handful of Weistec dynos I have seen. So that would definitely be an advantage of the E55 launching at the strip. But yeah those Weistec Stage 2 #'s are ridiculously strong up top...so it may just be a matter of time before it catches and passes a Stage 3 E55 (or maybe not if there are TCU issues). I guess time will tell.

Care less which model it is , I just want to see an AMG in the 9s w/o NOS.

To extract "supercharged" power from the 63, the compression must be dropped.
Anyway the new 63 5.5 liter TT is the next logical upgrade, for all of us, 55, 63 and weistec 63 owners.

CharlyE500

I doubt that set up will run low 10's

e500slr

By the way wouldn't the 7 spd be a liability, I know it shifts faster but the 55 engines seem to make alot of torque down low and alot of power up top so the elimination of 2 gear changes could shave a couple of tenth.

The thing that I want to get straight is will the Weistec kit not suffer from the same problems of the E55 like quick heat soak with Stage 4 and cooling issues. It also doesn't have the TCU and ECU tuning market like the 55. I mean we have so many sponsors like Eurocharge doing great TCU and ECU flashes and reprogramming. What options do we have with the 63? Anyone doing it would also not have the luxury of asking for advice since not many people have the same setup whereas the 55 has this whole forum with so many members contributing and helping with troubleshooting The 63 sounds sooooo good though

There's another thing, how much can the 63 engine internals take?

Why?

CharlyE500

Dude, the best thing to do is what Yacht master said go for the new 55TT. If my budget allow, i might get one in 3 years from now. That thing with a tune should hit 10's And its newer style car. Just need to change that square usb look exhaust......

e500slr

There's NO chance for me to get the new 5.5 now, believe me I would but where I live the prices are literally through the roof. They tend to depreciate fast in the first few years then more steadily but it's more than 2.5x the price of a W211 E63. I love the sound of the 63 engines too.

By the way another advantage is the lack of SBC on the 63s.

CharlyE500

In 3 years from now, 55TT E63 should be around $50k to $60K...... good and bad thing about AMG they depreciate fast when its new.

e500slr

To be honest I'd rather upgrade now and then get the CLS63 in 3-4 years. I'm not too keen on the W212, I love it but the new CLS is just Like I said though I love the interior and the exterior and the sound especially of the 63s. A family friend bought a non-AMG W212 and to be honest the non-AMGs are UGLY. The facelifted W211 is a much better looking car. The AMGs I'm on the fence with, the W211 has an amazing timeless look and the W212 E63 isn't exactly ugly, especially when you put it next to the new hideous M5.

How is the 7-speed reacting to all that power?

chawkins2001

Curious why you think this way? Taking the stock blower off and adding an aftermarket blower is adding a whole new more efficient power adder.

Lets say for arguments sake, the weistec adds 150rwhp to a stage 3. How is that any different from putting your car on the bottle? The bottle is adding a power adder, and for arguments sake again, lets talk 150 pill hit.

Seems like a lot of folks on here think that be using the spray you are cheating. You are not, it is just another form of generating HP and making your setup more efficient.

A weistec e55 will get walked by a E55 on the bottle generating similar HP from their respective power adders of choice. This will be even more magnified on the street where it really counts

CharlyE500

I don't think and believe swap stock SC to Weistec will increase 150whp.

cahiil55k

Video proof or a timeslip, or this claim is as real as a unicorn. I recall reading about a CLK63BS with $150,000 in mods, including the Weistec, only running mid to high 10's. An E with the same setup would be far far far from achieving what this monster BS did.

BBBSS

63 is doing it on race fuel and has a ton more money invested to run practically the exact same times. I think we know who the winner for now is.

The new TT will be the E series game changer. For now I still believe for outright drag racing the E55>E63

GT-ER

The car you are talking about doesn't have $150K invested in the engine. It has about that amount invested into the entire car ( in the first few posts someone said his wheels alone were like $10K ).

AKnight55

Yup thats Jcart.. He may only be in the mid tens, but that is far from the best to come from that beast.. Hes putting down 660 rwhp, which is far more than any E55 out there right now.. I can see that car running in the very very low 10s once its dialed in..

cahiil55k

Yes, I understood it was not just engine mods but a whole bunch of other mods that improve it's ET among other things. It's still $150K for mid-10's in a much lighter CLK BS, which means a heavy E63 Weistec shouldn't come close to that performance. Stage 3 55K cars have run low 11's before (with no weight reduction) so a claim that a Weistec E63 would embarrass a stage 3 E55 seems far-fetched. I'd also be concerned about the E63's transmission. Weren't they rated for far lower torque than the old 5-speed?
