Just purchased a complete hydra boost brake system from Classic Performance Products. I will probably install it over the the winter, it came with everything needed to complete this installation.

I'm just curious if anybody has used this set up and if so how they like it!

 

I built my own hydroboost setup from various parts and pieces. I only have about 10" vacuum at idle, so it's a must-have for my build.
Overall I like it. Had to use the manual brake hole in the brake pedal. The vacuum hole resulted in a very high and hard pedal. Manual hole gets a good amount of travel but a pretty soft pedal. I might drill a hole somewhere in the middle.
There's not as much pedal feedback, but it'll lock up the wheels really easily. So you get plenty of pressure! Hitting the brakes also bogs down the engine due to load on the PS pump, so make sure you have a good idle. You don't want the engine to die because you turn while braking.

 

Thanks Oddball,my brake pedal only has 1 hole in it (pretty sure) so I'll start there the car was originally fitted with manual brakes.

 

Look again. Every 68 Olds brake pedal I've ever seen has two holes.

 

I'll check it out Joe!
