    Dragstrip tips/tricks: Fall 2017 - Spring 2018 Race Season

    Guest-only advertisement. Register or Log In now!
    Hi all,

    Having a difficult time finding the last one, so I'm starting a new one. As many of you know, the Fall 2017 - Spring 2018 is the season that many drag racers not in the snow belt are looking forward towards. Why? It's our opportunity to run in 50-60*F temps and near 0ft D/A's for optimal performance and 1/4 mile times. Here are some tricks that I've learned along the way, and I'm hoping others can chime in on their experience with tips/tricks as well

    1) Go into it having a fun time with your friends. Although I get serious when I'm behind the wheel of anyone's car, the purpose of me going is really to help my friends and have a great time away from the daily grind of work.

    2) Monitor your tire pressures to ensure that they are set to whatever level you need them to be at in advance. For my particular track (well, actually for two of my tracks I go to, 39/38psi front/back works well for me and my preferred method of launching).

    3) Remove unnecessary weight from the vehicle that you don't want in there: spare tire, jack, fuel levels, luggage, etc etc. I chuckle at this one because I've been known to run at 1/2 tank of fuel and spare tire/jack in the trunk. But I would still recommend removing it.

    4) Remove dirt from your car. This isn't to make sure your car is nice and shiny, but it's to reduce the chance of that dirt hitting the track surface and causing the prep to become worse. You don't want to be part of the issue, you want to be part of the solution.

    5) I would recommend against using tire shine...no matter the brand, that stuff does swing off the tire.

    6) I would recommend against flashing your car up to the day of the track event, you'll likely end up with some strange occurrence during the run and not run optimal times. Flash a few days prior to, give the ECU time to adapt, do a few multi-gear and single 3rd gear WOT runs. during this adaptation period. **respect all laws, this will be at your own risk**

    7) Practice your launch method or what you plan on doing at the starting line. On B8.5 cars, you may need to switch from D/S, to D, back to D/S to engage LC or the LC sequence.

    8) Go around the water box if at all possible. Since we cannot do burn outs, this doesn't bode well for our cars.

    9) Do a LC start in the "burn out" box to clean your tires

    10) Log your car, Remove all unnecessary VCDS fields so you can focus on more important tables. Here is what I use:

    - Engine speed
    -IGA_AD_1_KNK[0] (cyl #1 adaptation)
    -IGA_IGC_0 (cyl #1 actual)
    -IGA_IGC_2 (cyl #3 actual)
    -IGA_IGC_4 (cyl #5 actual)
    -Intake air temperature
    -Intake manifold pressure: absolute
    -Lambda probes actual: bank1
    -Lambda probes actual: bank2
    -RFP_AV

    I'll explain a few items. You do not need to log vehicle speed or throttle %/angle. It's pretty clear by the RFP_AV and Engine Speed fields when you are at WOT. Additionally, you do not need to monitor Charge air pressure specified value-MAP_SP, this value doesn't really add value aside from how the ECU is reacting to various inputs, but assuming you logged days prior to and know your car is healthy, and the RFP_AV field remains at "0" at WOT, this field is not needed. Also, I did not include the field Ignition angle: actual, again this is also not needed and doesn't actually tell you the full picture of actual cylinder timing. If you add the IGA_AD_KNK[0] field back to the IGA_IGC_0 (for cyl #1) (bold above) field, this will give you a better picture of what the base timing value should be for cylinders, and from there you can deduce what the adaptation/correction value's should be for the other remaining cylinders you decide to log in terms of actual timing.

    LOG your car days prior to to ensure the car is set-up correctly, your fuel is spot on etc etc... Running a 104 map with 104 octane does not always ensure that you will have 104 map performance. Although it's nice to trust your tuner, use your best judgement, logging is a valuable tool for you and for your tuner.

    11) Bring ice, cool down your blower whenever possible. If your track allows for it, go for a little drive on the streets outside of the track to cool down the blower even more.

    12) Do whatever it takes to get those starting IAT's at or below 40*C, this allows for optimal 60ft times (pending you are able to launch it effectively), and you'll likely end below your safety threshold. Lower IAT's allows for higher timing tables that your tune allows for, this in turn allows more effective use of the performance throughout a multi-gear run.

    13) Make sure your seating position isn't in the "gangsta" style position, this is a serious event, make sure your seat reflects a proper position too...

    14) 1st timers, make a few practice passes if you need to, that way you get a feel for how the car reacts to certain different variables (launch methods, IAT's, tire pressures, shift points)

    I hope I covered the general basics, if anyone wants to add more things below, or even ask questions out in the open for a few to answer. Have a safe time out there guys, the fun season is about to begin

    How about safety requirements based on times?

    It's been almost a decade since I went to the dragstrip with an LS1 w/ 150 wet shot. Friend told me I needed a helmet, so I showed up with a hockey one. I passed tech and never got booted.

    yeah, they will take any closed helmet really.

    Follow your track rules. Some tracks like mine don't require a cage if the vehicle is built after 2006 and you run lower than 11.5 (I think that is the time). Helmets are usually required for all S4/S5 3.0t guys as we will run lower than 14.0 at most tracks, so I would expect to bring at least a helmet.

    Great tips!! I know I certainly could have used ice and some drive around time the other night when I went.

    Yea Richmond where I'll be going is closed helmet snell rated and no cage required. Can't wait! If anyone else lives around the Richmond track let me know when your going im about a hour drive away

    How bout launch techniques for 6MT guys? Clutch techniques? Ideal RPMs? TC on or off? I'm assuming on, but want to make sure.

    Great info!

    Not sure about other tracks, but long pants and closed toed shoes have always been required for me. I saw a girl get turned down in tech the other week, as she tried to stretch her capris to her ankles, lol.

    I've also gotten a few words about an 'expired' helmet, and I know others here have as well. That guy still let me run, but if they are sticklers, make sure you helmet is not only Snell approved but has manufactured date in the last 5 years.

    This one is funny to me, as I was definitely the only person last week constantly leaving to cruise the backroads and cool things down. I even had people ask me what I kept leaving. Ironically, I ended up having better IAT control with my car on, hood open, and defroster blasted on high heat (IATs ~10C below ambient) in the staging lanes. Hot lapping worked the best for me though...maintaining air flow over the coolers and limiting any time for stationary soak. I'd kick the defroster on immediately after the run and leave it on until I hit the box again too. The difference between good and bad times were ALL about IATs for me. I imagine the S4 is all about IATs and launch technique/traction.

    Oh yeah- open the throttle up prior to the launch for a few seconds. This will also drop the IATs a few degrees. For the SQ5, we load up the torque converter, and this process of mashing the gas drops IATs 3-5 degrees for me. The launch/shift program will cancel after 5 sec or so, so I try to load it up for a good 4 sec every time for max IAT drop.

    I have to drop my tire pressure to around 30 to hook up properly with my Conti DWs. This is likely a result of a poorly prepped track and not the stickiest tires.

    I normally drive through the waterbox, then essentially launch the car at 5k rpms and let it spin through first.

    This accomplishes two things:
    1. It cleans off my tires
    2. It makes sure LC is engaged properly
    3. It's fun... RIP tranny.

    A bag of ice sitting on top of the charger if you are parking the car for more than 30 minutes does wonders for IATs.
    If you are making passes more frequent than that your best bet is to leave the car running.

    I watch the tree until the second yellow lights up. I then focus completely on my launch and don't watch the tree at all.

    I can consistently get <0.3 RT this way and <0.1 if I am really trying.

    I normally make 2 passes then let the car chill. If I run more than 5 or so hot laps the tranny gets too hot and starts getting clunky.

    Oh and I always take the long way to the staging lanes to get some air flowing before my pass.

    I got yelled at a few times ago for not having a fire jacket when running <11.5. I normally don't wear it unless it is cold or someone yells at me

    Speaking of tracks. I may come down to your area in October to give Portland density altitude and some E85 a try... (6 hr drive yay). I imagine you're gonna be pretty active?

    I flip the front defroster on and leave temp at 61. Loe mentioned this last year, haven't done much of my own research.

    I would recommend turning it on "HI" for the temp, that way you can ensure no condensation and max mode for the compressor. It turns on the front fans, which rushes air through the front HX to cool the fluids

    It better be the first or second week in October because I think both PIR and Woodburn close 2nd or 3rd week in October and don't open again until late April/early May

    Just checked PIR's schdule. Looks like friday the 13th is a good day. The 20th as well. Pretty sure Woodburn is finishing up their events during that time, but it is the recommended track. PIR is fun too though.

    Yup I saw one Wednesday and one Friday. Should be able to make it happen me and the to be wife are both off that week. I'll keep on top of the schedule hopefully Woodburn has something that week we can plan for..

    EDIT: Duh you right. PIR it is... just will have to figure out 11 or 13

    Good stuff, Loe.

    I would add; when staging, try to stage as shallow as possible. Just creep forward enough to barley trigger the 2nd staging light as this will give you a little roll out before the timing starts. Also make sure you are in the "groove" of the track. You want to be in the tracks the other cars have made. You'd be surprised at the traction difference between in and out of the groove. John Force style burnouts past the staging lights is generally frowned upon unless you're in a purpose built drag car! Also stay on the gas a bit longer through the traps. A lot of guys actually end up letting off early killing their trap speed.

    oh yes, definitely shallow stage and ensure you cross the finish line before letting off. Both good points!

    Even as a more seasoned dragstrip guy, I've been known to let off early without realizing that I did.

    Great thread Loe. I hope this also makes some people realize how many variables go into running a good 1/4! It's not just about the power each car makes or the tune you run, it's about prep, IATs and a good launch!

    Instead of a Go-Pro or like camara, have any of you all used a cellphone with a windshield mount that has a 12-13" flexible goose-neck hinge? I just purchased one off Amazon and hoping I can use my cellphone to capture video's and mount use the suction mount on the sunroof to capture speedo/tach during a run.

    My local track is finally going to open (hopefully this Thursday) after flood damage throughout this rainy summer season and our last damage caused by Irma. Happy to be able to make it out to my local track Bradenton Motorsports (40mins) more often instead of driving 2.5-3hrs to Orlando Speed World to land some times with my new set-up.

    ....still hovering around 90*F, no boost season yet for me.

TC completly off, dynamic mode, 3800rpm and dump the clutch (keep in mind I have the stainless steel clutch line without delay valve)

    It all depends on your clutch health, but most of the times, if the prep is good, the clutch will slip just a little and it'll make for pretty good 60 foots. If the prep is not so good, like at my local track, you'll spin all 4 wheels and still make good 60' times !

    Helmet and Fire jacket for cars 11.4 and faster. Try to show up with only 1/4 of a tank of fuel. Bring a tire pressure gauge so you can adjust your "hot" tire pressures...I like to adjust mine after I check in, but before tech inspection. Check/top off fluids morning of track outing when the car is cold.

    Going to try this out this weekend and see if it at least maintains temps in the staging lanes, where I sit for 30+ mins.



    800 watt capable inverter connected to battery terminals, powering a 800 CFM Air Mover, and 100% pump mod. Will post results!

    I've been talking about this all year! Glad someone is going to finally try it. What were the results in the driveway/parking lot? Did you crank the defroster on high temp as well?

    I plan on doing the defroster trick as well. I didnt try it out too much because I dont have the pump mod done yet (today I will). Without the pump mod, revving it to 2k while sitting still doesnt really flow much.

    Does your track actually enforce the jacket rule on a stock appearing low 11s car?

    How many launches would it take to get to that type of failure...?

    Also note to OP - I had no idea there were this many kinds of considerations/tips/tricks that went into 1/4 miles (I'm also 110% newb). Really cool, thanks for posting!

    3. I'm the guy in that video.

    Things to consider: I have a LWFW which is single mass, 6 puck JHM Stage 5R clutch which is super harsh and missing a marcel spring, CDV deleted with the USP SS clutch line. All those things take away driveability and smoothness. I was told to dump the clutch too, but with this setup,... Well you can see what happened. All those things combined, plus the fact that you can't preload the drivetrain meant for some really violent engagement.

    I just ordered another USP clutch line and incorporated the CDV back into the loop today. The clutch pedal is easier to push in now and is much more pleasant to drive. I have to muscle the gears a little more when shifting as fast as possible now because of the delay, but launching is much less harsh on the drive train now.

    I'm going back to the track tomorrow and going to try to perfect my launch and hopefully do so without any wheel hop. Wheel hop was what killed my drivetrain.

    a few things I've learned from my recent track experience:

    1) try to line up against another AWD vehicle, or line up against a vehicle you know you are faster. Not because of ego's, but because of safety. I had a 5.0 'stang crash into my side of the wall the last time out right behind me.

    2) try not to go to the strips with tires less than 150miles on them. They are greasy and do not grip well, the result is simply spinning no matter where pressures are set. Follow the proper break-in cycle for new tires.

    In regards to a fire jacket, my track knows me enough (the announcer and his commentary when my car lines up "doesn't look like much does it?" "Here comes a fast Audi"...) that I have to wear a fire jacket. I've made too many 11.0 second passes in the past that its more for my safety. In reality, 11.0 isn't really fast with supercharged stangs/camaro's, but it is fast for a street-tired class that I line up against. You can try to bypass the jacket if your track puts "N/T" next to your number, that way your time doesn't appear on the board.
