I went to my local 1/4 mile drag strip to get some baseline results before I start diving into maintenance and modifications!
It was my first time launching or racing one of these cars with an automatic transmission. Definitely a learning moment, especially after getting used to my 750whp manual 135i. Two completely difference experiences! It was hard to tell the 335i was even doing anything because the stock exhaust is so quiet :lol First-ever pass down the strip netted me a 14.71 at 95mph. Not great. I foot-braked the car and wasn't sure how high the stall would let me go before starting to spin the rear tires. For the second pass, I left off idle thinking that might help. It didn't. Lost a tenth to the 60ft, but seemed to go down the back half of the track faster. The car was a lot cooler on this run as it didn't heat-soak in the staging lanes like it did on for the first run. I've been wanting to test the accuracy of my Dragy device, so I had it on during my first two runs. I was impressed to find that it was within 0.03s and hit the MPH on the head! Take a look at the Dragy results below compared to the actual slips and you'll see each measurement is almost spot on. It's an awesome little device for measuring all sorts of stuff. 1/8 mile, 1/4 mile, 1/2 mile, 0-60mph, 60-130mph, etc. You can order one from Amazon or Burger Motorsports! Since the Dragy was so accurate and the track was packed, I decided to hit a couple backroads on the way home instead of waiting in line for 1hr per pass. For my third attempt, I held the e-brake along with the foot brake to stall up the RPMs. Once I was ready to go, I released both brakes and it resulted in a much better launch. Unfortunately, the tires spun on my first street attempt because the tires were cold. So I did a u-turn and went right back to the same spot and did a 4th run after warming the tires up. Same exact launching strategy and the tires hooked, resulting in a better 60ft and much better ET than my original 14.7. All passes were done in sport mode, without manual shifting. I let the car automatically shift for me to keep things consistent. I probably could've squeezed some faster times out of it if I shifted earlier to keep the car in it's powerband. I can feel the boost tapering off up top being stock. Best of 14.31 @ 97mph leaves a lot of room for improvement. Next step is some much needed maintenance. The car has 140k on it and has never had a walnut blast (to my knowledge), and it could use some spark plugs/coil packs. Check out the video of my runs, you'll get an awesome POV-style view of me going down the track

wheel hop breaks axles and diffs, if u feel it just lift and maybe try to air out the tires on the next pass 2007 E92 335i / VRSF 5" FMIC-Charge Pipe-DCI-Inlets/ TurboSmart Plumb Back DV / XHP / E50 Custom Tune by WedgePerformance / APEX ARC8 / MT ET Street / 11.71 @ 119 / Instagram.com/silent11n54 |

Its been my experience that the stock cars, even though they fall out of power up top, are still faster when shifting at redline. I think they just dont make enough power to make use of the next(longer) gear ratio properly. So its more about using every inch of that shorter gear ratio than keeping it in the power with stock tune. I was consistently slower every time when short shifting around 5.5k or 6k on stock tune. As soon as I let it shift at redline on its own again I found both better et and mph. And the dragy results are awesome to see, I love mine, my experience is that it is dead accurate also with my last car. Can't wait to put it on the track against a real slip with the 335 here soon.

I just walnut blasted my car and can't believe how bad the intake valves were. I've never seen anything like it. Hopefully this will help me improve my results next time. Check it out at the bottom of my build thread: https://www.e90post.com/forums/showt...php?p=24764054 Yeah, it's a pretty awesome device. I'm glad to see others here using it!

I'm thinking of getting very sticky tires on my spare rims but they are 17x8. What would be best tire size and which tire to get? |

Yes you should be significantly quicker than that.
You also have manual rear wheel drive, which is the worst combination for consistency or good results without a great tire on the back at least. 60ft isnt awful but its not good. Definitely seen worse. Where were you shifting? Take any datalogs at the track? Be nice to see your conditions you were running in. What was the DA? Quote:
If you spin at all off the line, the run is basically hosed.

No datalogs. What is DA? One thing about drag radials, do you NEED to do a burnout before the run to like "activate" the tires? And yeah, I would like to get the widest tire that will give good traction on 17x8. |

DA is a measure of how much air there is, even if you are at sea level the air could measure as if you are 3000ft above it depending on conditions. Knowing the DA helps understand your racing conditions and what expectations you should have for the run. If you told me you ran a 13.2 @ 110 in your car at 500ft DA, id say it needs work. If you say you did it at 8500ft DA, id say you were doing pretty good. A burnout isnt required for drag radials, i would do one, but if not I would at least want them hot. So if you drove to the track on them and its a warm day, might not be required, but I would always at least spin my tires get dirt and debris off before pulling to the line. And if they are brand new tires, either drive on them 40-50 miles before hand or do a real good burnout the first time out, they wont hook well until you get the first layer of rubber and manufacturing goo off. I would try shifting close to 6k+, your gears are long enough as is. Your mph isn't great, so I feel like between the spinning and short shifting you were giving up some trap somewhere. Always datalog your runs at the track, what better place to do it? Rarely on the street will you get a chance to run from a stop through every gear to near 120. Paints a good picture of how good the car is running and again can give us understanding of why you would be running slow like this. If the car is good on the logs we can rule it out and focus on driving and traction, if the log is bad then we can see what needs fixed. We can also see your intake temps, if they were extremely high it explains the low trap. If not, driving does. Lots of reasons to log and know DA.
