E350
I got c0cky and lined up with the Benz at the next red light. I got a little over my head and spun my the tires a bit, while the Benz hooked nicely and simply took off. My car is definitely tuned for torque, and my launch usually puts me ahead of most people. To my disappointing surprise, the MB had about a 2 car lead on me until 30mph. I kept my foot in it though and started gaining quickly at topend. By 80mph I was riding his bumper.
From then on we went through another series of cat and mouse runs from various speeds, and in 1st gear and the bottom of 2nd, the MB was hauling pretty hard (bless that 7-speed auto), but at top end I was all over it and pulling away. At one high speed point I was wondering if he was still going since I was gaining rather quickly, so I cracked my window and heard it still sceaming.
I always wondered how the new MB's are off the line since the older models, frankly, sucked. I am pretty surprised now at how MB has improved their off-the-line acceleration and now I'm even more curious about how the F/I 55's feel off the line.

However the new E350 is a blessing, its fast, great torque in the entire powerband and simply outshines many other engines in its class IMO not to mention its fuel friendly too.
I need a looser converter
What's the rear axle ratio in the Buick?
Weren't they like 3.08 or so stock?
Back in the day I could beat the Chev Impala SS cars (1994-1996) with my 1981 Olds Toronado.
I snuck a nicely built 403 motor and lower final drive ratio into it, very unsuspecting, especially to the primitive "ricers" of that era. Left the wire hubcaps on for the sleeper effect.
BTW I have run my CDI versus a P71 Ford Interceptor (2001 build). Puts the Crown Victoria to shame, badly.

200 pounds in the trunk later, I'm still racing
Now I'm passively thinking of a twin turbo once I put this car aside for weekend duties. With the whitewall tires, it's a total sleeper.

E500: more power, V8 sound, older tried technology
E350: more efficient, more power per liter
If they use the E350 technology to make the next V8, it will surely be a screamer!

and yes.. the CDI is a lot quicker, especially 30-60 passing..
)?I am very surprised to hear that a E350 can hang with it. How heavy is your Buick? Last time I checked, a LT1 Camaro/Firebird/Corvette will eat a E350 off the line.
This is the same LT1 used in the Chevrolet Impalas from 94-96. The Camaro/Firebird/Corvette puts out a bit more power and they have aluminum heads.
At best I think I could have recovered half a car length with a better launch, but not much more. That car just seemed to have much more traction off the line.

Team CDI is gonna have to take some prisoners! CDI....the ultimate Cannonball Run car if you got a big bladder!
I must admit I'm jealous at how cheap it is to mod those Chevy's....you can really buy some real power on a beer budget.
Eaton Limited Slip Differential for GM 10-bolt about $375, and that is a nice, very effective LSD.
AMG E55 LSD something like $4000 to perform the same function.
450 HP Chevy...about $5000 for the whole motor. 450 HP MB.....well, if you have to ask......
BTW I would put that 4.10:1 into the RoadMonster. Or at least a 3.73:1. You have a deep enough overdrive that highway cruising will still be pretty comfortable. Your launch/hole-shot would be absolutely stunning! I love seeing big, unsupecting looking cars like your RoadMaster leap off a light like a loaded spring, especially when putting ricers junk to shame!

My goal now is to break 15.0 on the 1/4 mile...
Another item is the transmission....what a slushbox. I have an old Ford Bronco with a shift-kitted (for towing) C6. What a crisp, decisive yet comfortable set of shift points.
In my opinion, the MB trans shifts way too late for the diesel, often triggering the rev limiter at W.O.T. Hopefully at least the Carlsson software will wake the engine up a little at the 4,000 RPM range and it will then cooperate better with the transmission.
Finally, the 1-2 and 2-3 shifts are just way too protracted. I know its a comfort thing deliberately engineered into the car. But I get no comfort knowing my clutch packs are playing tug of war with eachother instead of sending that power to the road.
Does anyone know of a tuner that writes transmission software for MB, or is the MB "slushbox" a mechanical limitation that cannot be overcome?
I guess in the end, why ask for too much performance out of a diesel 4dr car, but like Dyson, I just want things to work properly!

The torque elasticity is so good on the diesel, that I feel that it is during shifts that motion is wasted.
If anything, the 7 would be great for normal driving, where you could almost drive it like a plane and just "set the power."
Lets say you are at 0 mph, but are likely to be at a 65 MPH cruise speed. Squeeze the gas just enough to get 2200 RPM and leave it there, let it work up through the gears. With the 5 speed, you have a lot more RPM fluctuation, as each gear is held longer.

Anyone ever seen whitewalled drag radials on stock wheels? That will be a sleeper for sure.

4600-4700?? Wow, that's more than a w220 s-class.
LT1 I'm purchasing soon will be a Camaro Z28. Those weigh ~3700 lbs and have 330 lb-ft of torque at just over 2000 rpms. I guess that's why the z28s will eat the E350.
My Buick is exactly the same engine/drivetrain as the Impalas, with the exception of rear drum brakes (gone soon) and 2.93 gears vs. 3.08's.
I'd personally recommend a 95 since they are easier to tune (pre-OBDII), but there are OBDI conversions out there for only a couple hundred bucks. And there are many T56 6-speed manual Impalas out there. The complete swap takes a day and everything bolts right up.
If it's within your budget and you're bent on the Camaro, look for the LS1 since that engine is much improved over the LT1. The LS1 produces more power throughout the rev range, whereas the LT1 is a bit "peakier" (if you can say that about a torquey motor).
Good luck either way. Let me know if you have any questions.

As far as trunk goes, the trunk in the s-class is empty 95% of the time. I really don't need it. :p
I'm a huge fan of f-bodies and GM smallblocks. Any forums you're on? Or better yet, I'll catch you on AIM sometime.
