Thread: My v6 Drag Week build

  1. #1

    My v6 Drag Week build

    This is my build thread for my Hot Rod Drag Week event. My 2011 run was disappointing, so I am starting my build now.


    At Drag Week I ran a best of 15.1 @ 90.x MPH 2.1x sec 60'. No traction off the line. My best launches came by launching at 1100 RPM and modulating the throttle. I could not do my usual, rev to 3K and let the clutch out quickly as I mash the throttle. That resulted in me sitting there with the wheels spinning... Keep in mind the tracks were VERY sticky. The engine has a lot more to offer even in it's current configuration... . On the street on dry pavement, in first gear from a roll (5-10 MPH) I could mash the throttle and the 205 60 tires would let out a mighty squeal/mini-burnout.

    Goals:
    Overall:
    • low-13 sec pass.


    Body:
    • reduce race weight by 200 lbs. The weight of the car and driver @ DW2011 was 2875 lbs. So 2675 lbs.


    Suspension & tires:
    • 1.7xx sec or better 60' times.
    • qualify for Modified NA class.


    Engine:
    • gain 50hp. Dynoed at 175 whp, so ~225whp.
    • Understand and fix issues noted during DW2011.
      1. large %timing err
      2. erratic A/F

    Not sure I will get it all done by DW 2012, but going to give it a try.

    Final note for those considering going to Drag Week 2012+, DO IT!!! It is a blast even when things are not working right!


    Update on the current configuration of the car. (07/05/15)
    Engine: Mitsubishi 6g74 3.5L 24V SOHC
    "T61" Turbo (that is what it was sold to me as, but it is much bigger ~T67 or T68)
    Intercooler: Aluminum Turbo Intercooler 25.5"x13"x3.5", 3.5" Core: 24"x7"x3.5", 3" Inlet & Outlet
    Weight: Current Race weight: 2930 lbs w/ driver.
    Best Pass: 12.36@122 18psi of boost and pig rich (~9.6:1)
    Transmission: Stock A543 w/OBX limited slip.
    Clutch: Turbosunleashed 6-puck purple plate.

    Re: My v6 Drag Week build

    You were using the 205s at the track?

    Fat sidewall, (70) larger diameter 205s would never hold much of a launch on my van. (Hold on brake at 2000RPM, then throttle modulate, which would probably be an effective 1500 RPM, if I just went "into it" from 2000 they'd fry) In fact after the shift kit they would squeak going in second or third, when I was hard on the throttle.. Those were fairly grippy Kumhos. I could burn them on sharp kickdown from a 30mph roll. I know this is auto vs stick, but that's also a larger diameter by about half an inch and an effective 2nd gear ratio, though torque multiplied.

    The Nexen 215s I have on now, so far I have had trouble breaking loose, but the van has been on the sick list.

    2.1's are pretty good.

    Slicks
    LSD
    Maybe a 2 step so you can launch consistantly.
    Gearing?
    More power, I don't think 225 hp will cut it.

    Yeah, but that is 225HP of V6 GRUNT, not that buzzy Honda horsepower you 2.2/2.5 guys deal with ;-) ...


    ... okay I'm kidding, but it does seem to be something of a problem in that you can quickly overwhelm any grip you managed to find with these with minor upgrades, it all goes on the bottom too ... SMEC programming doesn't help though, it's like torque from 0 rpm to 2000, then fall on it's face because it pulled timing for emissions then turn it on again at 2700 ish.....then you fall off the cam at 5000.

    Re: My v6 Drag Week build

    2.2 dodge = 225hp and 400tq

    1.6 honda = 350hp and 210tq

    fail

    as far as grip is concerned.. the launch was the only thing slowing this car down as far as grip goes. I think the slicks will be enough BUTTT a diff pin at the min should be used imo because youl be doing burnouts before every run more than likely. an obx is preferable though. slicks and obx would make such a killer difference

    the whole point of this car is to be the fastest N/A no power adder 12 valve 3.0 in the world.

    Yes... I have a turbo 3LV6 car. This one is to see what I can do with the normally-aspirated setup.

    I have slicks. I plan on getting an OBX. I plan on going to a full coilover setup to make tuning the suspension "easier."

    Will 225whp be enough? Don't know. Can I find more power? Time will tell.

    Right now I am trying to get the 36-1 wheel and hall-effect working right.

    Re: My v6 Drag Week build

    I was hooking 23/7/15 slicks off the 5800 limiter in my 3.0 dynasty on Wednesday even with no burnouts.. Best 60' was only 2.08. I was able to spin them if i dumped it but other than that they hooked. Ran 15.2@88

    I actually think the next step to improve my 60' is raise my rev limiter.

    Dont push the red button.You hear me?
