800 + HP 63 AMG?

OK, guys - one of you probably knows something about the car described here. I got this in an email last night: "Driving 855 Dyno HP SL63 now on 95 octane"

No real description of the car, otherwise. The most I've heard of anyone getting on a 63 was 750 (on heavy nitrous) ... anyone have any info. or is this more "weather balloon" than "UFO"??

Its BS unless your running complete bolt on mods (Tune, LTH's, etc) while running a supercharger with 200shots of nos you might be able to get A stoker kit coupled with the mods I listed might help it get up there as well.
One thing is for sure, there is no way you will get these numbers out of a N/A M156 engine unless you are using forced induction.

95 Octane

Anything is possible but 855 Dyno and on a 95 octane? Must've been a typo. Unless it's UR!

My thoughts exactly. I responded with: must be a typo in there somewhere? Last I heard the record HP on a 63 was HEAVY nitrous, and still about 100 hp shy of the figure you're claiming (http://www.youtube.com/user/HPMotori.../0/i40CWiW_Bbg 631 WHP on C63).

The gentleman assured me it was a naturally-aspirated 63, with "every tweak that can be made I would say- cam, intake manifold, header design (sounds like fighter jet), major computer mods, FUEL."

Anyone seen this car? I want to believe.

I guess given enough money, anything is possible.... do you know if he was talking about 855 whp or 855 hp at the crank? Big difference

I remember a while back Kleemann built a 800+ hp ML63 twin turbo for some guy in Dubai.

95 Octane could be a RON rating outside of North America. Likely rating is at the engine but still that seems exaggerated. Also PS is rated slightly higher than here. I don't know, seems like a stretch to me?

95 RON is just under 91 PON octane (US fuel) which would make the kind of compression necessary to get that kind of power out of an NA car pretty much impossible ...

There were a few turbo and supercharged 63s built - never seen one do any serious off-dyno runs, though. I call vaporware.

A Tune d C63 with headers already kills a Lambo. If he claims its above 800 HP, he should race Buggati Veyron and see how he compares with that?

855 rwhp on an SL63. thats like 1000 HP on the crank. Please contact this person and have him give you details on what type of mods and designs is on this car?

I think what he meant is that a C63 beating a Gallardo isn't difficult, the standard C63 hold up pretty well with the least powerful Gallardos. Murcielagos alot faster ik.

Do you know which version of murci it was?

Nope, it was a few months ago....I mean the guy could have lied about the 800hp...might have been in the 7s but either way it was crazy. The benz could barley stay in a straight line for the first few seconds...looked like a muscle car at take off. It was awesome. If I mew the guy again, ill be sure to ask him about his mods.

As someone else said.. given enough money and expertise.. anything is possible.. take a look at the Hennessy Venom..

From their web site (if you want to believe their marketing speech)

Horsepower 1,200 bhp @ 6,500 rpm Torque 1,155 lb-ft @ 4,200 rpm Specific Output 166 bhp / Liter Bhp / Weight 767.23 hp per ton or 2.61 lbs / hp Boost 16 psi (1.1 bar) Fuel 93 octane
This is from a 6.2L V8 as well (my guess since they are heavy GM/Chrysler shop, its a modified Corvette engine)

According to my conversation with Keith (DADS) this wouldn't be possible to drive all-out due to the torque limiters in the transmission. The motor might make that much but can it be put on the ground?

Hence the statement, with enough money.. you do not just modify the engine, you modify the transmission, brakes, probably reinforce the frame, much bigger wheels, probably need to modify the oil and fuel delivery systems as well, add cooling.. essentially... you would end up with an all new car...

Probably with the life span of about 5000 miles before you blow something critical too

Keith claims there is no known mod to the transmission although I suppose you could make something if you knew the existing design well enough.

Fuel, absolutely. Cooling, probably unless you never drove it on road courses. Brakes would be fine as is. Frame mods, absolutely. That would be a lot of twist to the rear end.

My guess would be a completely different tranny.. although I am not sure how well that would work.

There is another member of this forum who transplanted a 63 engine into a CLS500 or 550, not sure, but either way, there was an issue mating the transmission to the engine, and while it worked, he had a permanent CEL, power steering was disabled, and I believe the ABS was disabled as well (similar to when in winter and you wheels keep spinning, that all the nanny controls disable themselves to prevent damage).

Dunno, but it is fun to speculate Or really.. just go buy a car that has 800 ponies in it.. or more (I like the Elise.. so the Venom would be awesome.. if I could afford it).

In my build I'm going to see how far the car can go without breaking. Hopefully the car gives warning signs ahead of time. Then I intend to back off into territory where the car can live happy. I'm figuring there is going to have to be a remote oil reservoir in the trunk or in a tube along the chassis somewhere with a couple of extra gallons of oil and cooling. Same for the tranny. Tranny's are easier usually because you can drop the pan and increase its depth most of the time and add dual pickups and windage trays to that and the motor. We will see.

First things first, ACG needs to get the blower finished today and start it up in Stage 1+ mode.
