      balancebar and linelock?

      is there anyway to use a hydroboost/balance bar and also a hurst roll control linelock? or any other way to lock fronts to do burnout?

      or are you forced to stick with a proportional valve when needing a linelock

      I see no reason why you can't install a line lock solenoid in line between the MC and the T for the front brakes.

      Many line locs esp the Hurst can actuall act as the T and even have a left over port for a pressure gauge.

      good deal, I didnt know much about balance bars except they replace the porp valve, so figured I'd ask

      Maybe I misunderstood your original post, but how are you planning on using a hydroboost with a balance bar? Generally balance bar set-ups are for manual brakes. But either way, you can do a line lock.

      I have hydroboost and a line lock on my rear brakes, so far everything seems to be ok.

      i'm just thinking hydroboost due to twinturbos
      engine is getting built very soon, just will do breakin Na/Carb prior to EFI/TT install

      Balance bars allow you to tune your brakes for optimal performance at one deceleration rate, typically 100% since that's the worst case scenario with respect to weight transfer. At anything less than threshold braking (100%), you will be under utilizing the rear brakes. Proportioning valves are a relatively simple approach to attempt to optimize a single master cylinder system for all deceleration rate stops from 0-100%, allowing increased rear brake at lower decel rates and less at higher rates as weight transfers from the rear to the front tires.

      Fantastic point that most don't know about

      Tobin, you hit it right on the nailhead. It's the "kneepoint" in the pressure rise that you are referring to. For those that are in need of a simpler explanation, balance bars are dead linear in the pressure(s) applied to the front and rear brakes based upon simple input force (meaning you hit the brake pedal and leverages apply to two separate master cylinders based upon where you have the setting (of left MC to right MC). What is actually being discussed here is the hydraulic 'variable' nature of the typical knob / lever type of inline (and also the stock block style OEM) type of proportioning valves. Might this be a "smarter" system as such? My opinion is YES for most all reading this. The real answer is microprocessor controlled "smart braking four channel antilock", but that is still a ways off from an aftermarket musclecar perspective.

      Where the hydraulic proportioning valve has the distinct advantage over the balance bar setups is that the rear brakes are much more active under most typical PT / muscle car braking needs, BUT deeply taper off the pressure to the rear brakes once the "kneepoint" is achieved. Translated into the simplest base understanding (meaning REAL WORLD), you want as much rear brake as your particular build can tolerate (but not to the point of bringing the vehicle into a tailspin under very hard braking). Read this, along with the further StopTech link included:
