You nailed it Tom! It's really funny how many E55k guys think they can hit 117-118 mph STOCK It aint happenin' they don't realize these traps were hit @ Sea level tracks w/1400-1600-negative DA (Basically unreal NON average conditions or 1/4 tracks, most the tracks on the West coast are 1000 ft + above Sea Level) They in reality Trap 113-116 @ BEST bone stock.

I am going to do a custom tune with LET next week. We will see what it can do at the track the following Monday.

Using the popular Patrick Hale formula on this page gives 10.547 s @ 129.24 with 775 crank (using run weight of 4600 pounds).

I've found that this particular formula, which I first read about in R&T some years back, works pretty well if you use as-tested weight and trap speed, at hitting rated horsepower--except for the AMG cars, for some reason.

You can plug in a few traps/as-tested weights and see for yourself....

Btw, as the author notes, all of those things are far less accurate at predicting ET than they are at predicting traps.

My SL65 weighs 4630 lbs with me in it and a 1/2 tank of gas. I don't know where 4800lbs came from. I also took my car to the track in mid August and trapped 120 with a DA of 2680ft. It was 87 degrees and had been raining out earlier in the day so it was pretty humid. My car is stock.

Improviz

Who said it weighed 4800? I used 4600 in the calculator, which is the weight including driver, which is actually lighter than your figure.

Post 2 said 4800 lbs + driver.

Improviz

Aww, crap, my bad! I searched for "4800" w/ctrl-f, but didn't think to search for "4,800"! Sorry 'bout that....

I'm sorry that I've been holding out on you guys, but I hope you all understand I wasn't in a position to speak.

I know the owner of this car personally, and it will go 130mph once they make a few final tweaks to the tune and IC setup. You heard it here first folks:

JUST TUNE AND COOLING WILL GET THESE 65s TO HIT 130MPH ON 93 OCTANE!!!

That'd be me. I didn't look up the weight but just guessed since I was calculating a raw order of magnitude time estimate rather than a precise number. Apologies for not providing more context on how I came up with the number.

jmf003

Nice work by Vadim and Victor! Your buddy must be very happy with the result.

So back to the original question, this car produced 578 rwhp and trapped 128 mph.

There are numerous SL65s available for $80-100K and they have low miles. What could be wrong, especially if the car has a CPO, with owning one? What causes the erratic depreciation?

Marcus Frost

First off, CPO only covers the car for an additional year our of original warranty.

Additionally, I was referring to not necessarily warranty items, as much as maintenance items. Rotors for these cars are $800 a piece. Doing an SBC fluid flush will cost you around $700-$950. These aren't things you can assume are things you can yourself, either. These are just some examples, but the same kind of applies for the E55s too. E55s now are in the 40k range, and people think that wow, the car is cheap, but when a maintenance bill or an out of warranty issue comes up, they have sticker shock. The price to maintain these cars does not deperciate, in fact as they get older, it obviously increases.

TMC M5

Yup...maintenance wise ..it is still a near $200K car. Just the rear pads from the dealer were quoted at $460...ouch.



Nope....I heard it first from the owner himself.

Hey, my dad has a 2008 S65 (non modded) but to be honest, you will have a hell of a hard time getting into the 130's in terms of mph. Its down right difficult, and what Marcus said the aftermarket isn't that developed due to the low demand of the 65 series cars.

Now once I get my SL65 BS I will let you know of what it is capable and after Vadim has a crack at it.

gripforce-cl65

I had both modded CL65 (559whp) and 08 Z06 (591whp). From my experience, I doubt any 65 will ever come close to Z in a straight line performance stock or modded. I have many videos to prove this. From roll ons, the stock Z put 559whp CL65 about 3-4 cars behind. When the Z was modded to 591whp, then it did put a few bus lengths. IMO, 591whp Z (spent 8K in mods) can 'murder' any 65. I'm sure your 530whp Z can put any modded 65 to shame.

Addicted2Speed

VRP tuned CL65 just trapped 129mph with ecu, intercoolers, and intake. Since SL65 is lighter, it would have no problem trapping over 130mph with the aforementioned mods, which are pretty much simple bolt-on upgrades.

I agree with most of you on the straight-line drag race, on the track, with a stock Z and a stock SL65.....but, having owned 3 high rwhp Vettes (440, 550, 600) I'm here to tell you that I think my stock S65 would out run, or nearly out run all of them on the street in a quarter mile....."street" I say.

My 65 is absolutely nasty from a dig......any high HP Vette (especially a MN6 Vette) is going to have serious traction issues from 1-2nd...possibly 3rd.

I've ran the scenario in my head a thousand times- my 600rwhp auto C6 with a 3200 stall against my stock 65....both on street tires, and both from a dig on the street-... my 65 wins in a .25mile as the Vette smokes the 345's on the rear all the way to third and is a **** to control/maintain a straight line......

Get some over anxious rookie in a Vette against my auto, heavy-*** 740ft lbs of torque 65 and he'll struggle to catch me in any "reasonable" distance.......again, IMO and speaking from personal experience.

I reiterate, on the track or with any decent traction on the Vette, the Z wins everytime.....but for short blasts on the street, from a dig, I'll take my 65 any day of the week

Actually, I think the Sl almost weighs more than than the CL, especially if you're talking a 215. That hard top weighs a ton. But yeah it def. shouldn't take over 800 at the wheels to crack 130, even with a 2500 or 3000 DA.

Thericker

Wrong the CL 215 weight is 4700-4900 lbs the SL 600/65 weigh 4500lbs

& the new CL weigh nearly the same as the out going 215, this has been discussed to death, as well as documented in many magazines & actual track hounds weighing both vehicles...

BenzBoy12

reallyy? I musta read the weights wrong somewhere. Or I just got the numbers mixed up in my head, lol. I thought the SL was heavier.

TMC M5

The W215 CL65 weighs 4,654bs

The W216 CL65 weighs 4,940lbs
http://www.intellichoice.com/reports...edes-Benz/CL65

I did see that they said the 2008 CL65 was 4,599lbs... clearly they weren't using the right figure because the 2009 CL65 didn't just gain 350lbs overnight. The W216 CL65 hasn't been tested in any US mags but it has been tested in European magazines. All those magazines publish the weight at nearly 2,300kgs (almost 5,000lbs) whereas the W215 CL65 was always around 2,100kgs.

Your results would have been more positive (CL65) if you had a better cooling system. (or if it was cold out) The ECU pulls massive amounts of timing as soon as IAT's rise. You could be down 100 HP at the moment easily, and not notice. Oh, and I would step up to try that 530whp Z at the track or 0 (or any speed for that matter) to 200mph. I've put bus lengths on stock Z's.

BenzBoy12

Those numbers sound right, that's what I remember reading, that the new one is damn close to 5k pounds. But somehow handles better too.

Fikse

I've seen a 2005 CL65 on a digital scale, was 4460......
