    I have been looking through the site and noticed the Time Slips page hasn't been updated for a while and I am curious how fast all our cars are, especially when we see some 'inflated' dyno numbers.

    Let the 1/4 Mile Dyno show the real power we're making.

    I am happy to compile a list of times (for VF only) if people are interested in sending me their times sheets and with the JC community approval have a sticky on the top of the page with the list? Something I am able to edit, but people aren't able to post in to keep the thread clean and easy to read.

    Something like, send me a copy of your time card and list of modifications.
    Forum User Name.
    Vehicle = VF, Evoke, Calais, SS, Redline, etc.
    Body = Sedan, Wagon or Ute.
    Engine = LS3, LS2, LFX.
    Engine Size = 3.6lt (LFX), 364ci (6.0lt), 376ci (6.3lt), 416ci (6.8lt), 427ci, (7.0lt)
    N/A = Naturally Aspirated
    Supercharger = LSA, 2300, 2650, 2.9 + Brand, Harrop, Whipple, etc.
    Turbo = Number and size.
    N2O = if you use Nitrous Oxide at the track
    Bolt-on Mods, Heads, Cam, Exhaust, OTR, Intake.
    Transmission, Manual or Auto (Please list trans type, 6L80E, 4L80, etc.)
    Converter = High Stall only if applicable.
    Diff Ratio = 3.27 - 3.46 - 3.70 or other if non-factory.
    Tyres = Street or Drag Radials and size.
    Track = SD - Sydney Dragway, AIR - Adelaide International Raceway, WB - Willowbank, CP - Calder Park, etc.
    Date.

    Do we want to include RWKW as tuned or keep that 'secret' as we all know how people love to inflate their actual number, and the variation in dynos across the country.

    Then from the Time Slip I will use 60', 330', 660', 660' mph 1000', 1320', 1320' mph. Id ask for two time slips so I can see the Race Number is genuine (and backed up) and you're not sending me some 7 sec blown outlaw car on a bad run for your N/A 6.0 to run an easy 9sec pass. :)

    I can then look at breaking them down into separate lists for Blown, N/A, 6Cyl, etc as we get more input.

    As an example, mine would look something like this. I'd need to look at putting it in excel format so it could be easily sorted as new vehicles are added.

    GMVPSS
    VF2 SSV Redline Wagon. LS3, 376ci, N/A, Heads, Cam, Exhaust, OTR, Converter, 3.70, M/T Drag Radials, 285/40R18, Calder 01-07-2018.
    60' - 1.645
    330' - 4.837
    660' - 7.462 @ 93.423mph (150.35kmh)
    1000' - 9.711
    1320' 11.611 @ 121.993 (196.33kmh)

    What do the racers of JC think??

    Are you only interested in official drag strip info, what about reporting from VBox or Dragy type GPS loggers? Would they be (especially 20hz GPS loggers) be of any interest?

    As a drag racer myself I wouldn't be interested in those numbers as I would be questioning accuracy of the data and the users calibration, etc, etc. However if enough people were ok with the numbers being included we could have them noted as being GPS et and MPH under the track. (ie, SD, WB, CP, GPS.)

    Thanks .05,

    The car has just clicked over 7,000km so it is still pretty new (and tight). It should be faster than it is, (the mph is showing should be a very low 11) and the 60' is slow so the next bit of tuning is going to improve the off idle power to try and pick up ET to 60'.

    Being a wagon it is heavier than a sedan or ute, but still that's only 0.1's of a second (100Lb = 0.1sec in ET.)

    Higgins CNC Heads, Harrop Cam, Harrop OTR, SDC Converter, 3.70 Holden Diff. Engine and trans tuning. At the track I use Mickey Thompson Drag Radials so I don't have any tyre slip issues. I also have Coil overs with bump and rebound adjustment.

    Fuel economy is good and bad. Good on the freeway when the converter is locked and sitting on 100kmh I can get 9.5-10lt/100km easily. However as soon as I get into traffic (stop start on the freeway or around town) due to the torque converter requiring more pedal to get the car moving, fuel economy can easily go up over 25lt/100km.

    My long term average over 500km is at 18.1lt/100km at the moment. Acceptable for an almost 600hp daily driver.

    Realistically, how many users on JC race their VF's?

    I hear You, maybe we need a recruiting drive because there would have been 20 VF's at Calder last Sunday in varying models. Lots of 10-sec LSA's there!

    Decent time for a heavy car...they are jekyll & hyde when it comes to fuel economy (highway vs cbd)

    That's a shame, because those boxes are used by V8 Supercar and other series race teams all the time, for lap data, G-rates, braking rates...all coupled to video of their laps etc. These aren't dinky boxes...the one I used was near enough $1500 piece of kit. Some of my friends who drive 8-sec cars at drag strips, use them to dial-in on long private runways, where they can spend a lot of the day dialing in.

    I guess we all don't just live right near a drag strip. But, I'll contribute when I actually go to one. I'm more of a lap driver, straight line at an approved strip meet, is a once-off.

    Good luck.

    Awesome results GM

    Have always liked the drag strip and taken my cars and motobikes there since I was 18

    Sent you all details, maybe I've broken the ice for more to follow. Good luck with the thread will be watching with interest

    Mike

    Here is my timesheet from last Wednesday at Sydney dragway. I'm right lane

    '16 VF2 SS-V V Redline auto with only a tune. My first time at the drags and first run ever. I didn't do a big burnout as my tyres are nearly at the end of their life (19k kms on the original tyres) and forgot to torque boost.

    Unfortunately only got to the 1 run as the track got shut down to due dew on the track thanks to the weather.

    Left lane was a FPV F6 Typhoon auto with work done. I had him until the last 100 meters.

    Mate, what wheels have you put the Mickey Thompson drag tyres on ? I'm trying to find a set of cheap wheels that will clear the Brembo's.

    The factory Bridgestone's are woeful when it comes to handling the bit of extra power mine has

    Hey Pete,

    I had Koya make a special set of Forged wheels that are 18 x 10 +57 and fit the Mickey Thompson 285/40R18 tyres under the guards without rolling or trimming. They're tight on the inside (within 5mm of the inside of the body) but they fit.

    Being Forged they are expensive and Koya may offer the same size in their 'Semi-Forged' range which are a bit cheaper. (The semi forged also fit over HSV brakes which are bigger than the Brembo's)

    I saw guys at Calder a couple of weeks ago running off the shelf wheels that stand out past the wheel arch and look crap and scrub the tyre on launch and going over bumps. Not good.

    They're advertising them on Facebook as their 'Drag pack' wheels so make sure you let them know where you saw them so they know they work I did with them to get them to fit (after they and everyone told me they wouldn't) was worth it. :)

    And I made the centre caps myself. :)

    Nice. I bet those cost a pretty penny.

    Not too bad. Custom design and machined to my specifications $1,350.00 each. Everyone gets to benefit from my work. :)

    Tyres are reasonably priced these days, considering how bad the USD is at the moment.
