SLR performance from our E55's!!
 

Well fellow e55 owners - I'm on a quest!!

Have done extensive research and see that w/K2 upgrades & w/IC pump we can easily expect 11.7's @ 122/123mph! I want 11.5's @ 125 on street tires. I've had Chris @ C2D in Tampa do some research for me as I had a "brainstorm" of an idea when studying the SLR drivetrain, that now appears not possible:wall: :wall: :mad: :mad:

My upgrades which start Monday @ C2D:

Kleeman K2 - ECU,Headers,Pulleys
Kleeman upgraded IC Pump
Forged 19x9 & 19x10 Wheels (CCW Wheels at 20 lbs. each- 32 lbs savings)
Evo Lightweight rotors (34 lb savings)
.....the unsprung weight savings in theory should give 1 to 2 mph's in 1/4 mi.
Upgraded snorkel
Investigating an added "cooler" for even greater efficiency(ala Evosport)


Now the Big added Mod:I was trying a 3.06 LSD Rear Diff

With that the 1/4mi 3rd gear would redline @ 125mph and would pull thru the 3 gears like a Freight train!!!!

Cory @ C2D informed me Yesterday it won't fit - different casing!:wall: :wall:

Oh well - I'm now looking into a 2.82 LSD - Should give me 1 to 2 mph in 1/4

Between the 2.82 and the lightweight wheels/rotors, I simply need 2 to 3 mph's, and I'll have my 11.5 @ 125!! Lets hope for the best everyone.
I'll keep everyone informed as to the progress of the transformation.

Rock: Thanks for your help with directing me to different lnks as well as bringing back your K2 write-up!!...Everyone else who helped direct me-Much appreciated!!:zoom: :zoom:

Did you try talking to kleeman or quaife about making you a custom gearset... like maybe a 3.27

Jeff

Wow!!! This should be good.

I think you may be able to hit your target with the mods you list. I know you will hit your pocketbook.:)

Make sure to get a baseline dyno as well as numbers at the track before your creation starts.

Best of luck and keep us posted.

Actually- Kleemann is the one that Chris of C2D has been talking to.(I believe)
As to the Quaife design,... I really don't want to be the Guinea pig.
The 3.06 I was inquiring about was actually a Benz/AMG design that they put into the SLR's. It just doesn't fit the E's.:mad: :mad:

As to the ratio-YES a 3.27 would be rippi'n in 2nd and 3rd-The issue there would be SERIOUS traction issues in 1st, + you would now have some high revvin beast on the hi-way (and I am consistently running 85-100mph :zoom: :zoom: on long hi-way trips, ie: too many rpm's for me..lots of Gas:X :X )

bigger pulley and some more boost?? lightweight battery in the trunk? the stock battery is HUGE....

Only at the track once some 15 months ago(early March '05):

Moroso:
temp was 58 degrees
Good track conditions - engine "cooled" each run - 2 runs - stock rubber
no mods - traction control on - "manual mode" w/automatic shifting

12.41 @115.8 - 1.98 sec. 60'
12.36 @116.5 - 1.91 sec. 60'

I live 3 miles f/Moroso and have 1/4 mile "stripes" in front of my development on SR710 and I am consistently running 115mph+. (at least 50-75 times over the last 2 years so I have a solid base in 1/4mi. trapspeeds!!)

Ken,

Keep us posted on your quest... :y

What's your secret?
 

How did you manage to get 12.36 @ 116.5 out of a completely stock car? I don't recall seeing any other stock car, on stock rubber, getting that good a time. Please tell me what sort of magic incantations delivered that time.

My best is 12.49 on drag radials! My car is otherwise stock. Is the track at Moroso downhill or what?

I ran 12.07 @ 116.3 stock, on the conti's..... slip and video here:

there are a couple of people who acutally went high 11's stock.....

Thanks for the secret formula
 

Geez, I must really suck. I'll try that next time. I'm likely stomping on the gas too hard, and invoking the ESP. I'm sure I'm at less than 1.0 seconds to full throttle. Must...resist...mashing...throttle....

All hail the mighty housclass.....11.84 bone stock.

The dream run.

:bow:

It's not that uncommon. I ran a fairly new, stock E55 on stock Contis, 12.35sec 1/4 and 1.874sec /60' @ 111.8.

Holly mutta frickin' sh**t... That's crazy time for bone stock! :bow:

It's called MOROSO in perfect weather!!

The track is @ Sea Level and in the winter months the air is usually real fresh and clean. It makes our E's run "Crisp". My 2 times @ Moroso are actually only slightly above average compared to some that I've seen. I see the common time's as 12.4's to 12.6's. Come down to Moroso!!

:zoom: :zoom:

........12.169 for me at Moroso on a cool crisp night...........
But it was all in the 60ft time - 1.787 - on stock tires -
Trap speed was only 114mph
100% stock car 9000 miles - the night before I traded the E for the CLS

LEMME BE THE FIRST ONE TO SAY IT>..... REAR AXLE SWAP... then get halfshaft adaptors bolt into the SLR diff:smash:

MKB do a rear diff to 2.82 ... and they will remap the tranny. They may have other ratios to play with ...

Rgds Steve.

Another 100% stock time of 12.16 for my car on the stock Contis. 1.85 60' on that run, but I have run a 1.77 60' on the stock tires.

remember that one time u almost lost to a E430.....lol
