Darn close to 4.8k I reckon, already have 4 wheel disk and the manual setup did not come close. I have it good now but only get 2 good stops before the vac runs out of the can and booster. Really like the hydro, but the vac pump is so much easier and all of my componets are new. Idle and low speed is my problem, the vac never gets above 8-10. stop and go will suck.
