I was browsing online when I saw this:

Can you imagine tuning with that 6.3 litter engine and those upgraded turbos.

Too bad I don't live in the UK or this would be worth looking into

It says 640hp and 1026Nm, that's not much better than a stock 65? Aren't you just better off tuning a 65 motor to 7-800+?

Yes if your goal is just 700-800 crank hp. If you have exhaust, intakes and a tune, that's good enough for your goal.

But if your trying to make more your really left with cylinder head work and work on the turbos. After that your last option is engine work and that's really going into the unknown on these cars.

Only Brabus offers upgraded engine internals on the R230 (idk why Renntech never did, seeing that on the old R129 they would mod the old SL600 to 7.4 liter displacement)

Also this is an SV12 roadster not an SV12S roadster, SV12S came around 2006, same time the SL65 came out. The SV12S uses same engine but I assume better turbos to crank out 730 crank hp since they didn't do turbo work on SV12. Then on the 2009+ version of there cars you start noticing quad intercoolers and custom intakes for there 800 hp cars.

This car is prob gonna be worth it if you plan to maximize your mods. Doing R&D work on making custom cams along with larger valves and bores might cost you more if this is a single project car.

For 39999 pounds (around 65,000 USD) that's not bad esp considering it also has the full Brabus treatment (body kit, interior, 12 pot front brakes etc)

Well I was wondering why they didn't go farther, but I see they did later in the -S version.

FYI Brabus actually starts w/a regular 600 engine, they bore it too 6.3 liters and add 65 cams/heads/fuel injectors etc.. They use 600 block vs 65 as there's much more material/room to safely bore to 6.3 liters etc.. Though tuning has shown the dif between a tuned 600 w/5.5 liter & a tuned 65 6.0 liter is MINUTE, IE the half a liter in larger displacement isn't the main defining factor in power diference.. It's mainly the amount of boost bet the (2) motors & the slightly larger impeller wheels, then add nominal dif in cam/heads.. Then you see even after tuning the 2 are still nearly equal when BOTH run 20-21 PSI.. (funny I forgot Brabus actually upgraded the turbs too.. Further proving the added displacement is JUST for bragging rights etc)

Nod def goes to 65, it will have about 50 more rwtq but about the same rwhp after both equally tuned & will run 2 or so higher mph & 2 or so tenths faster in 1/4.. Adding Brabus .3 in bore size is literally for bragging rights and only reason they did it.. Note Brabus final crank hp/tq #'s after tuning? Vs just tuned 65/600? About the same

Tuning a turbocharged platform by adding BIGGER turbos is BEST way to easily/safely add more hp/tq (you can add ton of extra power while still running same amount of SAFE boost IE 21-22 psi) You don't need to add more displacement.. Vs Boring Natty v12 to 7.4 liters is the ONLY way to hugely change HP rating on Natty engine..

Ever wonder how they pump 1500-2000 whp outta old skool Supra's w/tiny V6 motors? GIGANTIC single & double turbocharged setups (obviously supporting mods too, but huge power on turbo app's is dictated solely by turbo sizing etc)

Last bit of proof Brabus 6.3 is purely publicity stunt.. From the add Just TUNING 65/600 it will sprint from 0-60 in just 3.3 seconds..

I'm certain the Brabus 0-60 is on unprepped city streets, but on prepped surface etc it wont best 3.3 seconds w/only 640 bhp.. A tuned 65/600 will make between 640-650 BHP..

no..i cant imagine.

0-60 in 3.3 seconds sounds a little optimistic Thericker
But as you say for the money you pay for the Brabus you can pick up a 65
AMG, some people would prefer the 65 just for the badge.
I think my 65 with it's re map might manage 60 in 3.8, but not 3.3, as I found out that day when I tried my luck against a GTR , 60 in 3.2 I think.
and I would agree

Benz-O-Rama

Thericker is actually spot on, with this one. That's what my car does 0-60 in on drag radials at the track.

Street tires on the street? Forget about it... I just measure the amount of rear tire smoke, rather than seconds.

I kinda meant that, trouble is I don't smoke .
On paper a 65 should do 3.3 just never seen it, especially with only 2 WD.

Read it & weep professor Car & Driver tested a Renntech tune ONLY 2004 SL600 & on the street (guess it was just warm enough to achieve really good traction the day they tested it on STREET tires to boot) 0-60 3.6 seconds 1/4 11.90 @ 120+ mph.. Read quote below, and how it bested the supercars of the day back in 2004 when C&D wrote this review


http://m.caranddriver.com/reviews/me...trumented-test

Now as I posted above ON sticky drag tires on real sticky 1/4 track these 0-60 mph times have been documented by many in tuned SL600's (Ahem.. resident track STAR Clayton) they drop to 3.3 seconds or even a tad quicker.. A STOCK SL65 will not do this, ONLY after a legit aftermarket tune will it match these 0-60 figures

Notable correction.. SL600 curb weight is quite a bit less than SL65, C&D listed 4500 lbs for SL600, it's been well documented since to actually weigh a tad under 4300 lbs, while the SL65 w/slightly bigger heavier engine & true LSD rear end weighs 4500-4600 lbs

This isn't the BEST technique for lowest 0-60 but it's what most of us do on the streets from my Verizon Wireless Tablet

I am not suggesting these figures are not true, but they all seem to be under the right conditions. You always seem to meet a 911 or GTR when
it's either raining, or you have just been cruising and nothing is ready for
the race. It's not like doing a couple of quick bursts ,and get ready for
a 0-100 if you see what I mean. Also if you put me on the drag strip
against a stock 65 driven by a regular drag strip driver I bet he would win.
I don't go racing but I consider that I am a reasonable driver who likes
speed, but at my age your reactions are slower, so even with drag slick
tyres I doubt if I can reach 0-60 in under 3.8, I'll leave that to you experts.
Now can somebody help with some codes..

That reminds me of a 997 911 Turbo S that was at a red light with me back in the spring and I was actually excited to go at it, to find out it was an old guy cruising my face went from to

But back on topic Idk that would be a tough call picking an SL65 over a Brabus car. Only reason I say that is I haven't seen many full option Brabus cars in the DC metro region or anywhere for that matter in the US, most I see is car with Brabus body kit and wheels, with maybe a tune.

Only time I ever saw a fully decked out Brabus car was when I was in Abu Dhabi, U.A.E in Spring '13, I was heading to a meeting when I saw a fully decked out W216 CL600 with the SV12S package in the parking lot. I think Brabus cars are more common in the Middle East and Europe over the US. From time to time I always try Google or Ebay and don't have any luck with the full package Brabus cars.

Only thing is if I ever did get my hands on a Brabus fully decked out R230, I don't think I'd drive it as a daily driver as I do with my SL65. If I rake up 100-150k+ miles on my SL65 and needed to swap for another SL65, It wouldn't be that hard, maybe a little time consuming to find one that was properly being taken cared of, but replacing a Brabus car might be a real challenge, but 65,000 USD for 20k mile car that was hard to come by I'snt bad, esp with that black on red combo.

Now if only someone can come across a Fisker Tramonto off the SL65 lol, Even though the performance is the same, the styling of the kit they put on the R230 imo is amazing, too bad they didn't make many of those cars either.

Just curious how the 0-60 times are figured from a 1/4 as I have never seen a 0-60 time listed on a time slip. I have only been to two different tracks however. I have seen a few spreadsheets that calculate 0 to 60 based on the the 60 foot, 330 and 660 times. I broke out a times slip and got a calculated 3.63 0 to 60 time. It was on street tires, but of course on a track with marginal prep. Does that seem believable
