What If Build Ideas...for Land Speed Racing

Yes, I saw that too. They did it and it may behoove us to know their recipe, I again, am just getting my head around all of this. All that I have seen had single pot master cylinders as well. yikes.

So I am building a 68 Charger which is giving me all of the thoughts on this. It will get at least the C500 aero package. but the best solution would go Daytona just to help with the HP aspect:
Drag Coefficient:

Charger 0.484
C500 0.411
Daytona 0.28

Likely the best solution is just build the car, learn, go out and talk with people and come home to build a purpose built car - unless by some miracle, this one would be close to useable.
Single pot brakes is not really a big problem on the salt. 2 mile runout and parachutes allow time and distance to slow and stop. Remember that the air drag at speed will do a lot to slow the car just by getting out of the throttle and cutting fuel.
Liners and lakesters have very low CD so rely more on fuel cutoff and then the parachute. If you had road race or NASCAR brakes the low traction would allow the wheels to lock up.
Fuel and blown alcohol dragsters and funny cars do not have much for brakes, relying on their parachutes. They could install powerful brakes but that would add weight they do not want.
