Hey guys


I just talked to my friend and he told me that his cl63 will be tuned with 600hp(crank). He doesn't know all the details yet, but what do you think it takes to bring extra 100hp to 6.3 engine. No NOS.

Thanks

Dr. G

when your friend making these claims gets some details, report back!

600hpvette

A tune will yield about 10-15HP max (from what I have heard). This engine doesn't have as much room to tune due to it being naturally aspirated (no supercharger or turbos). I have inquired into what a 63 is capable of putting down with full bolt-ons and 70hp over stock seems to be the limit.

That is exactly what I told him..

I am checking evosport BS project, http://www.evosport.com/product/vehi...BZ_CLK63BS.pdf

They claim: Power Gains1:+65-75 HP/+60-70 ft.lbs of torque with Evosport exhaust & evo2 ECU upgrade and headers. I know these are imaginary numbers. I just don't see how they can get 600hp..

BoBcanada

engine was tuned to handle 580 hp... so the max you can get from it is 580 hp.

You see the price on those headers alone!?

I am used to modifying Corvettes, I am not used to the Mercedes tax yet. This stuff is ridiculous! To think people complain about 1500$ for headers in the Corvette community! I am pretty bummed about the 6.2 liter motors mod potential. The 55 seems to be the best bet for modifiers, I like the reliability of the NA motor so I shouldn't complain...

Greg

Karlson

Yeah, very price. I wonder how much power does Brabus/Carlsson provide? Renntech gives +35hp. I think 600hp with cl63 is a bs.

Thericker

I don't know the pricing on these badboys? But should push you very close to 600 BHP I.E. 500 rwhp w/Ported Heads/Long Tube Headers/ECU/hi-flo cats/Under drive Pulleys/race Gas

Add Bump-Sticks to this combo & you'll have a beast! I too have modded plenty of Chevy/Fords in my day, my last was the C6 Vette w/6.0 liter had every conceivable bolt-on + 3.90 DTE gears...

Also LT headers for the C63 are $5000 and the cheapest tune is $1500

Are you trying to add 100 hp to stock CL63 or just reach the 600 hp mark? The CL63 is almost at 520 hp at the crank. Reaching 600 would require squeezing another 80 hp or so not 100, so it maybe doable. To date, the only mods that have been shown and "proven" to make power on the dyno and on the track are those two:

1) Tune + Shorty Headers = +30 to 40 hp gain
2) Tune + Long Tube Headers = +50 to 60 hp gain

Some argue that the carbon fiber air boxes give you another 15 hp but the only two people I know who've actually tried them on the dyno showed no difference what so ever. The 63 engine is very difficult to mod. The only other easy to squeeze more hp out is to reduce weight. Evosport was able to gain an additional 25 rwhp by switching stock rims to dymags ($9k upgrade ), which put their car right at 500 rwhp. Here is an initial dyno graph from their CLK63 development car (belonging to jrcart):



And here is another one....




Also, some people claim that they have hit 480 rwhp on dyno dynamics with MHP long tubes + tune but I don't think it's been verified yet. I'm guessing with heads and cams, you maybe able to squeeze another 40 hp or so....

DAGREEKNYC

We hit 464rwhp with everything out for the car except long tubes and exhaust , we went with Kleeman headers and a set of hi flows leaving a set of stock cats as well

stevebez

Without F/I the only way you hit 600hp+ is making it rev... so cams / valve gear / headers / cat delete / straight through pipes.

May need to look at induction system to .. filters / TB etc etc ... Mind boggles at the work involved. Its a sweet engine and should be happy revving... so who knows?

At first thought I said no way... but anything can be done if you can get it to rev and breathe.

Karlson

what does a handicap c63 engine have to do with my question?

Karlson

well, anything is possible. I am talking about realistic numbers. I just don't see that possibility, kleemann nor renntech can provide this numbers. Cams and valve gears got a lot possibilities, I just read couple threads that 6.3 engine is pretty maxed out and max out is 70 hp, that someone posted before.

nrgy

Probably because the mods would be similar/identical to achieve 600hp on a c63 as it would a cl63 or any 63 for that matter.

But the link Thericker posted (going in a c63 btw), those mods should do the trick

Karlson

please....


I trust evosport more than Andy...

nrgy

Trust whoever you like, but you wanted to know what it would take, and I think that's what it's going to take regardless of vendor.

Karlson

I wanted to know REAL numbers and what would it take to achieve them, but not Andy bs, aka tranny tune for c63. please, don't be offended by my post. I just want to know real numbers that can work with 63 engine. I should rephrase my post, before I get crap from other members. Evosport got a proven result with 60 hp and probably 10hp with carbon intake. So it makes it 70hp over stock. I guess 600 hp is possible with date that Mb_forever post

nrgy

I understand, and no offense taken. While I am very happy with the results from my MHP headers, I know how many feel here on MBworld in regards to MHP. But there's been rumor of Kleeman coming out with K3-K6 packages for the 6.3 engine by the end of October. New throttle valves, optimized cylinder heads and cams, claiming an est 630+hp. I think those numbers are probably optimistic, but I guess will just have to wait and see. Not sure if you've read this thread, but check here: https://mbworld.org/forums/c63-amg-w...confirmed.html

MB_Forever

MKB and RennTech are also both working on some more upgrades for the 63 engine. In addition to the proven 60 hp from headers and a tune, expect another 40 hp or so from the upcoming mods: heads, cams, etc...

Please note: the above figures are only my conservative estimate based on my experience with the 63 engine; these estimates do not in any way represent claims or posts from the manufacturers.

TTMotorsports

Are you eventually going to run for public office Mo?

You are the most politically correct person I know(especially on MBWorld)!

Don't forget where you get some of that 63 engine data from!

MB_Forever

LOL.... I was just trying to avoid off topic arguments before they start. Usually someone will jump in these threads and start arguing claimed numbers: 10 hp here and 10 hp there until things get way off topic.

Never

Full Throttle

This is funny tell your friend to sell his car and buy a 55. 80hp without juice is not going to happen.

Karlson

tell me about that Too cheap for him

Full Throttle

Hahaha more like to fast for him.
