stock cl65-604hp/738tq
from what i here an ecu'd 600 will give you 600hp/700tq??
will these cars run dead even or will the 65 still kick azz?
trying to justify spending another $20k-$30k.
i believe the 600 weighs less then the 65??
anyone test this?

Renntech quotes 620 HP and 740 foot pounds for the S600. Evotech may be even higher.

Is the CL600 a "hand built" engine like the AMG? I do know that my CLK55 had forged components. Does the CL600 have the same forgings? Same CAMs, etc? I am pretty certain that Renntech can tune a 65 and get higher performance than their similarly tuned 600's, right? So, the question might be... Which one can run that those levels "reliably"?

I still haven't had a chance to run a tuned 600 in my stock '65.

Based on people's dragstrip experiences, I think the two would be very close, since either will trap at 120-122 mph.

The AMG pkg of course gets you much more...the seats, brakes, wheels, better sounding exhaust, less restrictive ESP, and of course, the potential for even more power with an ECU.

As far as reliability, the AMG motor will be more reliable. It has a better factory cooling systems, and countless internal modifications to handle the extra power, including oil cooled pistons.

I use to have a 2005 SL600 with the Renntech ECU/TCU and I raced a 2005 CL65 3 times. Twice from a roll and once from a stand still. We were dead even on all accounts up to about 110 mph when we both had to brake.

I know own a 2005 CL65 and it feels identical to my tuned SL600. I assume if I tune my CL65 it should easily beat a stock CL65 or tuned 600 engine.

I think they would be even and it depends on the power of each car. We have seen some 65's dyno in the 510-550 range stock and we have J on here whos 600 was 525whp last I checked and may be higher now. His car runs very strong and would keep up with or beat some 65's. I am not sure if the 65 has any different cooling set up over the 600. J and I talked about this and our airboxes and intercoolers seemed to be the same as did our ic pump.

My personal take is that the 600 engines has been detuned "badly" so that it doesn't outsell the 65 engines.

Jay's car has proven that it can run faster than a tuned 65.

france2112

I'll have to disagree. Jay's car is amazing no doubt and it was tuned by AMG. But his engine is 5.5 liters compared to a 6.0 liter displacement and it has smaller turbos. If you tune both engines by the same people to the same boost level the CL65 will be more powerful. Traction will be the only issue from a stand still but from a roll the CL65 should win every time.

Jay's car was built on Sunday... everyone else's was made during the week.

So in reality it seems that the current S600s are actually mislabeled 12 cylinder S55s since they only have a 5.5 liter displacement.
What displacement values were S600s prior to the current S600 models? Shouldn't the S65 be a 6.5 Liter engine? It seems they are off by 1/2 liter based on the usual nomenclature rules of past.
What is the displacement of the 6.3? I forgot
Anyway, I got to sit in a white CL 63 today. Absolutely gorgeous car.

Here is a stock CL65 dyno, 559/670, anyone here dyno their chipped CL65?

S600s have always been 5.5 liters. S65s have always been 6 liters. S550s are 5 liters. S63s are 6.2 liters. Marketing.

DoctorV8

Weird...that's my car,,,but I never posted it. Wonder who had access to my timeslip?

Tires were wet at the strip (had to drive through the burnout box), so that ET was meaningless.

Whoover:

One correction: the S550's engine is 5,461cc's which would properly be rounded up to 5.5 liters.

DoctorV8

Nope, the pre 2003 non turbo S600 was 5.8L

Sorry, the S550 is truly 5.5L.

Also, the S55 AMG, along with all the other AMG 55's are 5.4L.

mb advertises S/SL/CL 600 having the same engine as Maybach but slightly detuned 550hp vs. 495hp (510hp on 2007 and on) also S/SL/CL 65 has the same engine as Maybach 57/62 S(604hp). most sources states that 65 engine is a bored version of the 5.5 in 600s with larger turbos/intercoolers. brabus enlarges the displacements of both engines to 6.7L which makes about 720hp. this should prove that both engines have the same potential. 65 will be more money to buy less money(by brabus) to tune in used market. however buying a brandnew 600 and let brabus tune it should cost about the same as a brandnew 65 with having 120hp less than the brabus.

All this talk about HP you can get a small block Chevy to do that or a Viper but I like a car to handle, too.

Substance

which chevy makes 500+hp out of N/A 6.2L V8? Last time I checked 6.4L vette produces 440hp. its more like 7.0L Chevy < 6.2L V8 MB(505hp vs. 518hp) most sources states the 6.2L engine unstressed at 518hp. the potential is around 580+hp in N/A form.
there was an article some months ago in car and driver. they compared 6.4L and 7.0L corvette engines to 6.2L AMG. AMG was superior to both in all aspects but the cost(17k for 7.0L vs 70+k for AMG)

sd964

I believe grane was refering to the 07 Z06 7.0 Liter 427. It is a small block!!

Can you send a link in regards to info you stated? Thats sounds very interesting.

I have personally witnessed Jason beat up on a SL65 in his tuned CL600

V12Godspeed

Was the 65 stock...I see that happening.

blackbenzz

Yes, the driver claimed it was stock

Substance

I dont know the link but i had the issue a couple months ago. I will post it if i can find it. I believe the title was push-rod vs. overhead cam.Corvette's 6.2L V8 and 7.0L V8 vs. AMG's 6.2L V8 DOHC. AMG was breathing 40% percent more due to 2 overhead cams. AMG was too high tech comparing to Corvette'a 7.0. AMG was lighter too. They focused on 6.2L Corvette and 6.2L AMG due to similar displacements. However AMG was stronger than 7.0L too and they also stated AMG 6.2 was unstressed at 518hp could go up to 580 easly in N/A form.
