HYDROBOOST POWER BRAKE SYSTEMS.

[POWERBRAKEBOB]

I bought my Turquoise car new. It was originally a Chevrolet Show Car. It now has 254,000 adventurous miles on it. Since it will never be a "showroom stock" car with high value. I have decided to address some of the issues not addressed here before.
The "idea" behind the secondary port system was to use a short duration cam for high vacuum and smooth idle reasons. When you commanded it, the secondaries would open to a longer duration cam profile
The factories have always had their hands tied with big cams and vacuum for power brakes. That was why Chevy did NOT want to sell the L88 to the public. NO vacuum to work the power brake in traffic.
Having looked at the computer wiring mess hanging over the vacuum booster, and with my secondaries blocked open, the booster just needs to go away.
With the installation of a HYDROBOOST (which is my business) I can use a common 1 inch master, eliminating the expense of replacing the PBR Australian master, which is only 7/8". The HYDROBOOST runs off of the p/s pump, and no vacuum is used.
HOWEVER, with the Hydroboost, I can move the battery to the rear, remove the vacuum booster completely, remount the computer where the battery was, and route the monster computer harness UNDER the Hydroboost. This will be a HUGE cleanup of the engine compartment. I plan to powdercoat the booster, and then all the aluminum engine pieces in a metallic silver color, instead of polished.

I put a hydroboost set-up from an astro van in my syclone.I was able to hold 8 more #'s of boost over the vacuum system before the brakes let loose.Definately more brake pressure.

So what does a hydroboost system cost for a ZR-1?

what is all needed?

YES! I have been doing many Turbo Buicks, and they can hold up to 22lbs of boost without Redlighting using the HYDROBOOST. Yes, ALL the forums talk about the junkyard Astrovan units. I started doing Hydroboost conversions 30 years ago, and now I am THE Authorized Bosch Distributot for NEW Hydroboosts.
It has so many advantages here on this car, and I didn't realize it until I kept fighting the computer bouncing around, looking at the wiring harness, and I detected a vacuum leak in the booster. With the secondaries blocked open, the vacuum is a little weak.
I have included BEFORE photos of what I am referrring to as to the location of the computer, the harness, and the obstruction of the vacuum booster as to the cam cover
