    Helpful to understand how to engineer and use a transbrake, two step and bump box, thank you

    You should do one on wiring a trans brake and a bump box

    if your car is rocking like you are saying if you have a line lock you can run that with your transbrake. it will help a lot with your rocking when you bump in

      How would you install it with the transbrake? Wouldn't you want your line lock on a switch so you can use it in the burnout box too?

      No most cars don’t use line lock for burnouts

    Subscribed because of how well you explain things to newbies. I'm interested in doing this one day (drag racing), would like to build it all so it'll take me some time. Video's like this help.

    Sweet I came across your channel because I decided to run a th400 instead of s 4l80e bolted to a 8.1 I’m putting in my 66 impala. I want a trans break so I’m just trying to learn how to install them.

      You're just depressurising the entire intake. Takes time to fill it back up again. BOVs aren't for performance, they'll just give your turbo more life. Listen to rally cars, F1cars you often here inpeller flutter because they're not running BVVs

    • @Hoonmaro
      @Hoonmaro 5 років тому +1

      2 step yes cuz it's just two different rev limiters usually one lower for launch and then after launch kicks off and then just becomes your normal rev limiter

    • @JohnDoc

      +amari odom 2 step is pretty much an adjustable rev limiter that can set for your launch rpm

    • @MmeDesgranges
      @MmeDesgranges 7 років тому

      Two step means you per-determine your launch RPMs in advance and program it into the box. Then on the night you just engage two step and nail the throttle. It takes away one more thing to get right on the line.

    • @negativesplits06
      @negativesplits06 4 роки тому +1

      When it comes to launching, it takes a lot of fine tuning to launch @ the right RPM. If you launch too low, you’ll bog. If you launch too high, you’ll spin. With a 2step, you can set a limited @ a desired RPM, so you don’t have to manually hold that RPM while @ the line. You can just floor it, and the 2step will set a limiter @ your desired RPM to launch optimally.

  • @robbyking8756
    @robbyking8756 5 років тому +1

    All racers with a studder box, and a trans brake launch with there foot to the floor, that bump box has to be tough on the trans brake and torque converter, when you launch your boost drops to nil then it takes about 2-3 second for it to make boost again turbo lag there's no way around it dude, supercharger owns turbo for drag racing turbos are shit your basically racing all motor, deep staging is stupid as fuck it's not gonna make you run a quicker time like people think it's like 6 inches, none of the street outlaws run trans brakes, studder boxes, hood scoops, or heat shields, I don't understand why no one runs hood scoops anymore they give you more hp I guess in there mind it catches air so it will slow them down I guess lotta things they do like running this huge ass 36x36 tires that's just fucking stupid that's a hell of a load on the motor a tire weighs a fuckton when it's spinning at 200 mph
