Drag Racing is Like Drugs
I just can't seem to kick the habit. Took the lowly 335i sedan to the drag strip again today along with Mike (Alpine_e82/Car Whore) and brought back some more numbers with some progress. This time we went to Gainesville Raceway instead.
Vehicle Specifications: '08 335i E90 6AT JB3 1.3_8C2 map 8 (really map 7 based on 1.22 list) 275/40R17 Nitto 555Rs @ 21-23 psi stock airbox, stock intercooler, stock DPs ~100 octane - Sunoco 260 GT 100 octane, 1/8 tank DA: (167ft elevation, 63 decreasing to 57F air temperature, 30.03inHg, 37 increasing to 41F dew point) @7pm (1st run) = +443ft @8pm (5th run) = +185ft @9pm (6th run) = +50ft Adaptation routine: Been running on 100 octane all week. Tried to run the tank as empty as possible in 3 successions. Went to the pump and dumped in 5 gallons of the good stuff in Jax and drove down all the way to the track with the same tank of 100 octane gas. 1st run: 60' 2.114 1/8 8.213 @ 91.43mph 1000 10.538 1/4 12.492 @ 115.35mph *1st gear launch with not too much wheel spin 2nd run: 60' 2.146 1/8 8.262 @ 91.13mph 1000 10.595 1/4 12.551 @ 116.23mph *1st gear launch with very mediocre launch 3rd run: 60' 2.138 1/8 8.237 @ 91.46mph 1000 10.564 1/4 12.519 @ 115.66mph *1st gear launch with more spinning 4th run - 2.208, 12.741 @ 114.63 (lane I ran in apparently was very slippery and they decide to clean it after my 5th run) 5th run - 2.342, 13.081 @ 114.60 6th run - 2.158, 12.789 @ 113.12 (an hour later after nonsense track prepping) Compare it to last time at Orlando Speedworld (3/21/09): Quote:
**8C2 seems to be progressing/improving nicely from previous versions of JB3 1.3. I want to thank Terry for listening closely and adjusting his tune accordingly. **I have reached a crossroad in determining what to do with this car next: trade up (GT-R or 997TT) or add more bolt ons Witness: *Mike (Alpine_e82/Car Whore) had some great runs. Got a much better time (12.2s) and much higher trap this time around (119.8 mph or something) - He has a 135i 6MT with JB3 1.3_8C2 Map 8, RR DPs, Code3 FMIC, 245/45R17 Nitto DRs, and DCI. |

Point taken. That's why I'm considering trading up to a GT-R, GT3, or maybe a 997TT for some track fun. The 335i feels like it needs quite a few more mods before it can really be my worthy weekend track car.

Another near stock car achieving 116+ mph traps. Very impressive.

Or you could start bolting more mods on and break into the 120+mph club. |

+100 to drag racing addiction
Nice runs. Better grip may be in order but have you tried a 2nd Gear launch with the AT? I thought HotRod has done this consistently. |

My issue tonight was not because of the initial launch (1200 or 1500 rpm brake torquing and releasing does not cause it to spin) as I hooked perfectly every time on the holeshot. But as the boost rapidly kicks in and I get about 30' into the strip, I've already rolled the throttle too far and cause massive wheel spin before the shift to 2nd, which I continue to spin. Ideally, I would back off to stop the wheel spin and try to keep my tires on the edge of adhesion. Does not work with this car. My 5th run, I had rolled the throttle so slowly with wheel spin still and the tranny decided to shortshift to 2nd. Killed my start but I had to keep it that way to not slide across the track. I conclude that it is most likely the track being dusty and dirty as others were having the same exact problem that I did. In addition, I'll be needing real slicks as those that had them could launch perfectly fine (1.5-1.6s 60's). |

The Nittos take quite a lot of heating up and aren't that sticky even when you reach the right temperature. I see why many have moved to Mickey Thompson ET Streets or Hoosier Drag Radials since they are much stickier and heat up much more easily.

Here are the results to Mike's run:
We followed each other down to Gainesville Raceway and he ran right after me every time on the same lane. Quote:

Nice times guys....I almost made the drive up there. A couple of my friends did, i couldn't get away from work in time. My friends were the ones in the red C63, black e55, burgundy c63 and burgundy Viper with the nice big shot of Nitrous that trapped 140 My friend in the e55 said he saw your cars running.

When running, the 335i is very fun on a track.

Those guys ran some nice times, 12.0 and 114mph I believe in the red C63, mid 11s and 120+mph on the RENNtech E55. Didn't see how that Burgundy C63 ran with his DRs. That Viper GTS was insane! I thought it was stock until he opened the trunk to check to pressure on his NOS tank! Track was dusty and still spin city for us but it was fun. |
