So if my fuel is good, meth injection is working properly, why would my timing be so low? Because I am not CPS offsetting it?

Also, are you running stock DPs, Intercooler, Exhaust also?

I think what he's trying to say is, there is almost NOBODY who can reproduce your results with stock dp/ic/intake/exhaust. You can say we all have a reason to be skeptical.

Love the diesel. Whole different effortless powerband down low. I was driving it last night, and really enjoyed how easy it is to holeshot out of an intersection without even having to reach high rpms. And that is something when you can step out of the 120mph trap 335i, and still be impressed soon as you drive the diesel. Diesels idle leaner, and you can tell they use less fuel even at very slow speeds. As fully loaded the 335d M-Sport is, it also is very luxurious and has a very pleasant ride. I think the extra weight kind of makes it smoother than a petrol 335i. Maybe its the M-sport suspension, very pleasant ride. For an X-5, I would definitely go with the diesel. The gas X5s are really thirsty, without the low end grunt you need for a heavy vehicle.

Thx,
This is definitely pushing me towards getting meth...
Best I could manage was a 12.6 @ 111mph this weekend
-my mods (jb4, ic, dci, dps)
-map 7 w/sunoco 104oct 3/8gAs
-Stock rfts (1.9 60ft)
-1157ft elevation
-72degrees
- full weight + a trunk full o crap...

Disappointed kinda...
I ran a 12.6 same car with only jb3 map 8 & dci (1.8 60ft)... Colder temps though..

I have BMS DCI on this car..so not stock intake.
But the car idles, runs so smooth and quiet. Doesn't attract attention, and thats the way I like it.
The car is quite a sleeper.

Its hard to run at 1157 elevation, and an even higher DA. Famosa is around 648ft I believe. Heavy wheels hurt, all that weight in the trunk is really bad. Remember the more load you put on your car, its probably more likely to pull timing, etc.

Hotrod at what PSI does your meth spray?

I would expect near 10 degrees ignition post shift.

It comes on around 8 psi.

I was just going to do some test runs to evaluate the dual nozzles, but noticed meth spraying in engine compartment. At first I thought it was water from the rain. But tonight, with no rain, I was still getting the droplets all over the intake pipe area. Trying to find which of the myriad of connections was leaking to no avail. Finally I did a paper towel wrap around the connections and found the culprit connections. I'm going to recut some new line and reinsert the two sections. I'm not really a fan of these press-in compression fittings. I would rather have the ones where you slide the compression ring on the hose, put the metal insert in and tighten it with a wrench. (like the fittings that I use on the second meth nozzle valve)

It was legit. If I recall, the Vbox read about .60 mph faster than the time slip back then. In fact, I will try and find the Vbox screen shot, bet you it read 120mph. Besides, to do a 11.78 with almost a 1.8 60's time, will generally take better than a 116mph trap speed.

That same day I also ran at 11.87 with a pathetic 1.92 60' time. Trap speed on that one was 120.9 mph (would have been 123.5mph if ran same time in 2010. By far the fastest engine tune only record.

Last visit to Famoso, Terry had one high boost run just over 120mph as he forgot to bring his tuning resources for the JB4. But again, I am comparing against 335i BMWs, not lightened 135i BMWs.

On my 132.7 mph trap run at Sac, the Vbox read around 129.8 mph I believe. But on the other hand, I put in a new bottle and did a few 133mph Vbox runs. So fully 3mph faster than my run at Sacramento. I think you will find a car that can do a 6.9x 60-130 run is going to be running 130mph traps. Cars that run low 7's (ZR1, Carrera GT, Enzo, are all 600+HP, 130mph trap cars)

Hopefully more members can record some Vbox times at their local tracks.

With a 30 dry shot of nitrous, how fast do you think you can run at Famoso?

I upgraded most of my fittings to metal fittings to avoid leaks. The composite/plastic corrode over-time, especially with higher meth mixtures.

I think you can find yourself better timing. Its simply strange that your timing is unnaturally low considering meth and or race gas use and such low PSI.

On 17 and 18 PSI... Stock exhaust through and through. Stock intercooler ETC. I have 10+ degrees ignition from 4000 RPM to redline.

Are your boost levels reading correctly? Maybe your TMAP sensor needs a cleaning. I feel like you might be seeing higher boost then what is being read, especially since your timing isnt stellar.

But then again, now that you have a leak, most of the data is not useable. I guess you have more to look forward to as soon as you fix your leaks.

BTW you could have checked for leaks simply priming the pump? That;s how i found my leak. I pretty much do a daily test and prime on my meth.

Well here is a screen Vbox screen shot of a 133mph run, and 6.9 second 60-130. (soft easy launch), didn't hit nitrous till about 50mph. This was on a .28 shot. I don't really think there is a need for me to go to a bigger shot.

At Famoso this still would have been 132mph
At Sacramento, at least 135.7 mph

Its just a matter of the DA being good enough at Famoso to run these numbers. But in any case scenario, still a 130+ mph trap 335i.

[dlbrooks18]

^Wow, for such a small shot and low boost that is incredible, like HPF E46 M3 trap speeds right there..

[hotrod182]

Ran with the one CM10 meth nozzle, which oddly enough was faster than dual nozzles on my car, and had better timing. (will post Data later on the meth nozzle testing). The sedan trapped 121.4 the other night, but tonight I was just focusing on getting a good number for the 60-130 listing, with less then a 1.5% -slope. The 9.38 second run puts it right near the top of the listings on this forum. (Besides my coupe). Car seems to be getting faster and faster. However, under the same conditions the coupe would do 123.3 mph, and therefore achieved a time of nearly 9 seconds flat. But for no downpipes, etc, and using 91 octane instead of high octane not bad. Again...boost was nothing spectacular as you can see by the run graph.

Now I have heard all this talk about perfect/max timing graphs etc. I'm not interested in what perfect timing can do in the car if it is going to run like a slug. Can someone please show me the timing log of their car on 91 pump gas and meth, when they are actually running 121mph traps, or low 9 second 60-130 pulls such as my log below? I would like to see the exact comparison/analysis.

[Clap135]

I think u are confused about what good timing means. Your last log has good timing.

I'm sure I am. Not that familiar with what people are getting on actual 0-130, or 60-130 pulls on back to back runs, without racing fuel. Car feels great, and pulls hard. INterestingly enough, the things that I would think would result in worse timing on my car, (higher map, single nozzle instead of dual), will often have the opposite effect.

This is incredible... your 0-60 time is as fast as a Porche GT3 RS, and you beat it in the 1/4 mile.... not bad for a $50,000 car and a hand full of mods for what $5k?

Great work, and please keep it coming...

A lot less thank $5k.
Engine mods are probably around $1000 total:

JB4
Basic Meth Kit
DCI

Clap is right.....your timing does look good

If you think about it, as timing is advanced, cylinder combustion occurs under more compression since the piston is closer to TDC.

So it would make more power not less.

I think a car will feel like a slug when you pull out too much timing with offset or the DME does this on your behalf when there is too much heat/boost for your octane and it gives up and flatlines your curve.

that is insane... the results you are getting with $1k....

not a lot of people are getting these results with so little mods.... wow that is fast.

How accurate is the Dynolicious for the Iphone/Ipad. I did some runs with my D and did a 0-60 time of anywhere from 4.80-5.12 seconds. 0-100 was 11.16 seconds.

I have seen some numbers to be way off, and some close. Either way, that makes it undependable for useful analysis. Good enough for entertainment purposes. My Gtech was right on sometimes, but about 15% of the runs could be skewed. That made it to unreliable for evaluating performance increases with certainty. The Vbox is very consistant, and thats key. I'm not sure, but I believe dynolicious may be more mechanical accelerometer based than GPS?

ya, but he is posting his results and they are verifiable... they are incredible results hotrod...

I think they are better results than from people that have turbo upgrades - is what I just said correct guys? (and Mr 5).

Do you think I would get these results if I had Meth on the mods in my signature and match Hotrods track times?
