My last post was a little misleading...fuel system is limiting power made with current setup, so gathering data now and will implement a change in upcoming weeks.
Looks great, and love the wheels, but they must be a pain to clean!
Thank you! I'm digging the setup as well. Pretty striking in person. I had the wheels and calipers coated in a cquartz product, which I guess helps with dust accumulation and ease of washing. But, yeah, each window must be wiped down, but that's it....no scrubbing or harsh chemicals.
Got an alignment today and had 5 gallons of sunoco gt plus around....went to the strip! Fourth run was the best.
da = 2477
fuel = 10 gallons 93 and 5 gallons sunoco gt plus
mods = renntech lowering, bc forged 21s with msps, pure turbo upgrade, dme stage 3 file, upd catless pipes and filters
a stock M5 ran 10.9X at 127.xx at 3000 D/A a few weeks back. And a modded one with tune, gas, and DP's did 10.3X at 135... have you heard about these cars??

Thx bud. I read about the stock one, but hadn't seen the 10.3 one yet. Crazy how strong the m5 is man. Gotta love it. Its ridiculous stock ones are running 10s...bmw has done a good good thing!

Ah and my guy with the demon was there again. This time with the demon crate and race gas, and running skinnies up front. He ran 10.3 at 135 over and over. Just a little comparo. His car has more in it, as hes learning it still, but nevertheless, some info for the forum.
The way I look at it is I'm happy with my car stock, there is always gonna be somebody faster with more and more mods. I'd be pretty happy if I could run mid 11's once I get to the quarter mile track in Bradenton. Looks like for me Race Start is gonna be not useable as I use hand controls and pushing the brake while having the gas to the floor is a tough one.

I hear that man. The car is a beast stock for sure. I wasnt even going to mod this thing, and had plans to build a gla45, but decided to make this one a race car and not daily it anymore. Now it's getting to be full on race car, and I still daily it. Haha. Meth injection to be installed this week before we take some cars to new Orleans next week for 1/2 mile races.
we're bringing my car, a w212e63 with w3 turbos, meth, and and trans upgrade, a w204 stage 2 c63, and a w204 stage3+ c63 with nitrous. Should be fun, which is 100 percent the point.
Ya, sorry did not mean to say it like I was taking anything away from you, that is a very impressive time you ran and ya when cars are even faster it does add to the excitement level, I must be getting old. Years ago I had to go the fastest I could. I think if I was younger I really would consider a dodge demon for the track and do some mods on it, that would be a more cost effective approach I'd think as I'm sure parts when they went (trans, rear end, etc) would be a lot cheaper for the Demon than the Benz. I may yet be able to get the race start to work with my handcontrols, I have practiced holding the control down in the middle rather than the end and it does seem to work ( just tried it with the engine off, lol). I guess I won't know till I try.

I didn't take it that way at all. Appreciate your perspective. And, yes, I bet you'll figure out a way! Do it do it
Little update...haven't driven the car much lately, as it's been suffering from the 'no boost after 4k rpm' symptom, due to the exhaust flap issue. Take it out every now and again to appreciate it's beauty and still in awe of the torque this thing makes...can get to surprisingly high speeds pretty quickly even staying under 4500 rpms. AWE exhaust (full replacement, mid pipes and back) will be here Monday. Upon install car will have full turbo back exhaust solution (straight through). Getting that system installed, and connecting the MWI system as well. Kevin Baldi is coming down to Orlando to dyno tune a couple of cars on 1/21, mine included. A member here arranged the whole deal; I won't mention him here, as it's up to him to do, but should be a fun day. Car will also receive the F1 camber arms.
After this last bit of tuning, gonna call it a day on this one, and just enjoy it...hopefully.
I'll post up some track numbers and dragy numbers once it's complete.
The 'stock' and 'tuned' numbers could have been better if I had been driving it properly, as I didn't yet know to shift out of first gear early to get best ET. Probably good for a tenth or two...first time I ran the car with hybrid turbos it went 10.86 on pump gas...on race gas and shifting out of first, picked up 2 tenths.
Meth/Water injection kit is installed; as is the AWE exhaust. The MWI kit is from Weistec (rebranded AEM), and of course has everything you'd need for a proper install. Compared to the w212 kit, the 213 one does not come with aftermarket charge pipes, so you are free to place the bungs wherever you like. Tank is in the trunk, wires/lines are all hidden, and bungs/nozzles are only visible if engine cover is removed...sleeper setup if that counts for anything. The AWE exhaust is just gorgeous. Gotta say it's really, really well done, and couldn't be happier. Definitely a volume change (louder) over the non-performance exhaust I had, and the tone is just amazing. So much deeper and racier, and less raspy, than the OEM setup. I'll grab some videos, but I doubt they do it justice; total beast mode with this exhaust.
Ran the car at the track this past weekend. New problem to deal with...traction. Never before has my car had 'real' traction issues at the drag strip. Sure, a little tire slip here and there, but now I'm dealing with traction control intervening due to major slip, mainly by front tires. I do have large (21") wheels with small sidewalls, so this probably accounts for part of the problem. Not surprisingly, tires will be needed to pick up on additional time, mph. I may invest in some sticky tires, but at this point thinking not likely, as I already know the weak spot on this car, and it's not the axles.
Anyways, I ran the car on 100 octane fuel several times. Will use higher octane next time to get more power, if I replace tires. Car ran a best of 10.74 and a worst of 11.22. Traction control kicks on two times per run, robbing power, as it's intended to do. Even if I can manage a strong 60ft (1.6x), traction control lights up after that point. I only run the car in traction control 'sport' mode, and do not turn it all the way off. This is to reduce wheel hop, which is what destroyed my car last time. I may put the stock wheels/tires back on to see how those do with the new mid-range power...I don't expect much of a difference. Went as low as 25 psi on the PSS tires, which helped, but car still couldn't hook up. I let launch control do its thing at default rpm launch to get the best runs. If I upped the rpm for launch, I was running over 11.0 ETs due to increased traction issues.
For those who are curious, it's the front tires that slip. The car launches aggressively, with nice rear squat, the rear tires hook every time with no perceived drama. The fronts however, struggle to find pavement, since the front end comes up so nicely. Next time I'll have my camber arms installed, and will try suspension on a firmer setting.

What is that then ?
Two things I can't understand in this car with all the expertise and technology of nowadays:
1) why the need for such camber values that shred tires? Because of the base E class platform? BMW has the 5 series and I believe they aren't so aggressive on the M5 to get good grip and handling
2) why the need for such a firm ride, even on comfort mode? Why having a great suspension from MB can't seem to coop with racing kind of driving (confort vs handling)

My bad man...assumed folks had already read rest of thread. Some early transmissions were weak...later production ones have held up better, including my second one.
No idea on camber control. Seems like it should be stock capability.
Turn traction control off, especially for the 60-130MPH runs..... 8+ seconds 60-130mph for an upgraded turbbo W213 E63 is NOT good....
I understand that bud. These runs were all done on the drag strip while launching the car . I will not run at the strip with tc off....been down that road.

Edit: 60-130s....ranging from 8.03 to a worst of 8.18. All traction affected with TC intervening and buffering rpms.
If you feel the front tires cause the wheel hop / trans issues, maybe get a nice set of DRs for the rear only, and try running it in Drift Mode? That way you can turn traction off completely and not worry about the front hopping / trashing another transmission? As you mentioned with how the car squats at launch, I bet a nicely warmed up set of radials would hook well in 2WD. Just a thought.
