Juiceee never ran 1.47 60' that's absolutely impossible w/the power level of the N/A cls63 Check out some of the online Dragracing calculators or and compare ALL the extemely HIGH trap speeds etc that Sacramento track coughs up, plenty of folks have admitted Sacramento's data esp Traps were totally off IE by up to 5-6 mph & later Track reported some of the Timing lights were improperly set/etc...
He'd need 660-700 RWHP NOT crank HP, & or 3800 stall converter, or change final drive ratio (gearing) to 4:11's & or modded to ALL wheel drive
I believe his highest RWHP Dyno's showed @ best 440-RWHP..

EDIT: I looked it up on Dragtimes weight w/driver 4450 lbs & 420 rwhp, on run in link near identical 1/4 ET but 60' 1.87 that makes much, much more sense.. Not trying to put you on BLAST Juicee, but that 60' in ur siggy is obviously an error from improper track lights, IE all your other 60's @ comparable ET's & Traps are ALL 1.80-1.9x![nix](https://mbworld.org/forums/images/smilies/nixweiss.gif)
http://www.wallaceracing.com/calc60hp.php Calculator-Enter vehicle curb weight inc driver, & 60' ran. It'll then convert it to how much REAR WHEEL HP you'd need
to achieve that particular 60' (obviously not EXACT science but VERY fair/true estimate)

Not hating on the SLR at all and I think that the 9.765 @ 140.87mph time is very... very fast... but there is something less impressive about this run when you start to consider how light the SLR is with the extensive use of carbon fiber from the factory...and how much money the SLR cost to begin with. Call me crazy but I would be more impressed if an E55 runs 9.9s given the starting point of both cars...

For a 4200 lb (being conservative as juice weighs 200+lbs so incl all weight reduction 4200 lb race weight is more than fair)

Yup... Also since he has so many other track slips on Dragtimes that compare perfectly in ALL rest of splits, if he indeed ran 1.47 60' his ET would've dropped dramatically, so from 1.87 60' to 1.47 would turn his 12.0x ET into a 10.2x-10.3x ET
4 tenths improvement on 60' = 8 tenths in1/4 ET..

So Cal guys NEVER see negative- 1000-2000 DA @ Sea Level, like the Eastcoast wonder tracks MIR/ATCO/etc They also have phenominal track prep vs tracks like Sacramento, plenty of peeps smack wall @ 1/8th... Maybe the F'd up timing equipment is the ONLY way we So Cal'ies can get comparable ET's to Eastcoast

IDK
Though that's where I plan on running my SL soon... I think the track owners reported fixing faulty timing equipment, though recent data still shows Sac Traps higher than national averages.

Don't forget about Famoso.... last month there was a mini private rental and DA was at -560 ft and track prep was great. It's all about good timing.... Fall and Winter will usually be your best bet at decent conditions in So Cal.

Loll nice resolution. Yea I bought one in late 2010 and it blew up shortly after. I'm not modding it again. Going to put the clk in the 9s. Although I think Weistec will get a E55 into the 9s

Few other +'s from CF shaft (tho I'm sure you already kno this stuf)
Weight is less than half Steel or Chromolly, IE my quote is 6-8 lbs vs 18 lbs
Allows your rpm's to spin far faster & higher
Documented to knock 2 tenths off 60'
Not to mention more Unsprung weight loss & drivetrain HP/TQ loss minimized

Damn! Sorry I had no idea it popped... I'm certain ur CLK has a lot more in it if you upgrade to some stronger custom halfshafts, & buy a Carbon Fiber Drive shaft (I've ordered 1) it not only takes more punishment but they state it dramatically reduces stress on ALL other driveline components as it actually flexes vs steel that either breaks & becomes pole-vault jousting thru ur floorboard
or custom pretzle machine like Jody![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)

So where is the mod list on this SLR? Cutting half a second off a 1/4 mile is very hard to do at those speeds without cutting alot of weight or adding alot of power. I know white is the fastest color but I dont think it's worth half a second
![Stick Out Tongue](https://mbworld.org/forums/images/smilies/tongue.gif)
#71
I would like to see the mod list myself. What do you think it has done to get that half a second off?
#72
Out Of Control!!
I don't want to speculate, I will just wait for them to say (if they ever do and hopefully they say all the mods). I mean Renntech already modded the SLR, it would take alot to then cut 0.5s off?

I'll say it.. Look closely @ rear wheel setup?? They are NOT thick drag radials, the actual wheels look like 19-20"s tho it cuts a 1.42 60' hmmmm IDK if it's camera angle or what but WTH is it running on rear? & sounds like running cutouts, though the stock manifolds/exhaust dump so close to front fenders stock maybe just LT's
#74

Post #23 from the owners mouth himself. The exhaust was changed. Also cf body kit and 50k suspension
Oh and they ran without a trunk
More mods coming!
