Initial Results with Noelle DPs and Dinan Stage 2

[wrsbmw]

It appears to have all worked better today but I couldn't find a level enough spot that was really long enough. Here are a couple of pretty decent quarters but one was completely uphill.

11.865 @ 122.88

11.892 @ 122.84

Both of them with 2.0s 60 ft times. Both of them mash and go in MDM with sport plus gas. I didn't do any runs where I disabled DSC completely and shifted myself. I will do some of those the next time out.

These are better than the day I tested with just Dinan Stage 2 and the open air box. However, they aren't as good as I could have done. I never really did get a good level run and so I know the results will be better on level ground.

Horsepower estimates around 650 from the trap speed and weight.

Thanks for sharing ! I am sure the heat has something to do with the 122mph. That should improve with the temp.

Yeah, but that won't get better until October or so.

[wrsbmw]

Just for grins, a cold start with Noelle pipes and Dinan exhaust now that the mods are all done, except possibly for the wheels which I am now seriously considering as the last touch.

Thanks so much for sharing.
Have not seen any head to head as of yet BMS vs Dinan

In the recent past just as a quick comparison what type of times are cars with BMS and DPs running?

It's very hard to tell what different people are doing because there are enough differences in the cars and mods and driving ability that the real improvements are obscured. There are people here who get sub 2s 60ft times and I cannot do that. If I could, my car would do a lot better. For example, I have a 11.865 best ET with a 2.0s 60ft time. If I could get it down to 1.6s like greentrbo or some of the other featherfoot types, then I would have a much better ET and possibly a little better trap time. My driving skills aren't very great but I do have a fast car that sounds fast.

The exhaust sounds great! I have a totally stock 2014 M5 and the factory exhaust is a little lacking (too quiet) in my opinion. But I am leasing so it is a tough call.

By the way, watch those hedge clippers to the right of your car. I can't tell how they are secured or how close they are to your car but it might be a close encounter with your paint if they were to fall!

I think -0.4 slope is close enough to what you'd see at a track. Don't these cars run around 122mph stock? I thought with downpipes and a tune you'd be looking at 126-130mph? Maybe it's not turned on?

It's not the slope, it's the waviness of the road. There are undulations in the pavement so it's not flat.

The previous results for my car were a best of 120 mph trap with 12.0 ET. The cars vary from driver to driver and with different components. If someone got 122 stock it was with a CP, not a 2013 stock M5. The tune is turned on but it has only been on for about 200 miles now and when I made the runs it only had 100 miles on it.

Motor trend guy got 120.3 @ 11.9 second with stock M5. He also got 122.2 @ 11.9 second with M5 CP. Both in good road condition and nice whether of SoCal using Launch Control!

@wrsbmw Thanks for sharing!
I'm just curious to see the result using Launch Control!

I will have to give that a try but I thought other guys had said its not that helpful?

If you are going to compare US car mag times, you need to use the GPS based ending trap speed which looks like 123.7mph since the car mags don't average the last 66' of the run like the drag strip or the vbox analysis above. Also most US car mags weather correct the acceleration data. I think Road & Track doesn't.

Dinan sounds even better with noelle dp!
Congrats and thanks for sharing!

[boots]

You'll get it right William. Just take your time. Glad your liking your car better. Your car sounds better now since adding the dp. When time permits we'll all get together for round two of some more runs.

Actually I went back and found some other members results with bone stock and it appears that my 12.0 with a 2.0s 60ft and 120.3 mph trap is about right for stock. Here is one that was completely bone stock with 11.9 and 119 on a 1.9s 60ft. Then with launch control he got 11.79 and 119.9 on a 1.85s 60ft. Both of these are comparable to my best "stock" result which was with the Dinan exhaust only.

Here is Stealth with a total bone stock car and he posted a 11.92 at 118.5mph with a 1.96 60ft time. He has a better 60ft and thus a better ET but his trap speed was only 118.5.

Definitely the tune and the pipes are having an effect and I expect it will get better with time. I will probably get better on the 60ft with more practice but I think the best I can expect without putting drag radials on is maybe 11.6 ET but that would be above 125 on the trap. Cooler temps will get me the faster trap and better surface will help too. I will try to get out to the spot on the I45 service road before it gets too hot, i.e. early in the am. Of course doing it in October would probably be about the best time of year in these parts to put down a really good number.

My fastest time so far on my bone stock M5 with CP was 11.72 @ 124mph. Here is my time slip from that day http://www.dragtimes.com/2014-BMW-M5-Specs-26190.html

Thanks for posting that. I think your CP result really shows how much difference there is in the ECU tune vs piggyback. I looked around on that site and found a comparable condition to what I am running in right now. This driver got 11.93 at 117.3mph with a 2.0s 60ft time driving a stock 2013 M5 last August 10 in Dallas.

So by comparison, my ET is 11.865 with a 2.0s 60ft and my trap speed is 122.8 which is really where the tune shows it's stuff. Obviously, 5mph in trap speed is a significant difference. This is probably the best stock to tuned comparison for the numbers I posted in the OP.

Sounds AWESOME. Glad you're getting some better numbers out of the Dinan setup.

My '13 has a stock motor and drivetrain. I did 11.97 @ 119.3 in early June when the weather was cooler. 60 ft was 1.9 s. That run was 'pristine', and I got decent traction right from the start. I haven't been able to break 12 s again, with most of my runs coming in around 12.2 s @ 119 as the weather got hotter. I think you're getting results from the upgrades. It's hard to tell from the graphs, but it doesn't look like you're getting 1 ft of rollout on your runs. If that's so, you can expect even better times at a dragstrip. Still interested in a get together with you and boots when the opportunity arises.

I just saw this thread. The dyno result of Dinan

Well that pretty much cinches it for me. Yours is the same experience as mine before the Dinan mods. I had a little faster trap speed but probably because of the exhaust since I didn't do any measurements before I added it. These are the best times I have had with any changes and your 12.2 is consistent with what happened for me after getting the airbox closed which is also when something got messed up with the DTronics.

Now I hope that I still have some room for improvement under these conditions due to more adaptation.

I am still interested in getting together as well. I think up there around Madisonville works well for all of us. Boots is putting his car in on Friday though since he ran it hard this past weekend. I am open to meeting up this weekend if you can or we can wait for boots and spinny to be available.
