Another type of system is called a plenum bar system. These are spraybars that are installed inside of the plenums of the intake manifold. Plenum bar systems are usually used in conjunction with direct port systems in multi-stage nitrous systems.
Famous quotes containing the word bar:
“I am of course confident that I will fulfil my tasks as a writer in all circumstancesfrom my grave even more successfully and more irrefutably than in my lifetime. No one can bar the road to truth, and to advance its cause I am prepared to accept even death. But may it be that repeated lessons will finally teach us not to stop the writers pen during his lifetime? At no time has this ennobled our history.”
—Alexander Solzhenitsyn (b. 1918)
