Is it possible to do extra 100hp with 6.3 engine?
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

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..

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...

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
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....




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.

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.

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!
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
