Converting to Hydroboost anyone ?
Permalink  
 


Thinking of ditching the whole vacumm brake thing and convrting to hydroboost. I have very little  vacuum at idle and sick of not having good brakes putting around.  I hear hydroboost works great. Anyone have thoughts, ideas, considered or have it ?

If you have little vacuum it may be a consideration. or converting to power brakes it may be an better option.

With the amount of HP your making Jim and the lack you have in vacuum. I would certainly recommend it. It also helps once you hit the traps on the other end since you enjoy running it down the strip.

Thanks Chris, I will start on the plannng & add to the winter todo list. I do not think it is that hard or expensive to do. Once I get an idea together I will post or try to move this over to the projects page. Or just add a new thread over there. If any others have thougths please share.

I thought the best donors are the minivans so look at them.

Chevy Astro and GMC Safari are the vans that you can scavenge parts from.

I have one, but it's not installed yet. Scott has one on the wagon, and he loves it...

I could have sworn I just read an article on it in the past month.

Actually I don't have hydroboost on the wagon. I have considered it, but heard about some guys having issues and held off until I learned more. It turns out there's a couple different ways you can plumb it, and one way is superior to the other for intense road course-style work. So, with that solved, I am reconsidering the upgrade...but to this point in time I'm still running an S-10 booster (8-inch I think) and a CPP 4-wheel disc master with isolated front/rear plumbing and an adjustable proportioning valve on the rear lines only.

I don't make much vacuum either, but you'd never know it 90 percent of the time. When idling around, there can be some variance in the pedal sometimes. But it takes so little pedal effort with those big brakes on the front that it still works just fine. At super low speeds I've gotten in the habit of pumping the pedal 1.5 times all the time (not full strokes, just a little double step) and that brings the consistency back.

Scott please share the plumbing ideas I seen this and was hoping this would work in my application.

From what I read try to have the T right off or as close to the pump or try to put a second return in the pump. Many run stock pump with no issues and many have issues. Most issues seem to be due to improper bleeding of system or bad return. Any one good at welding a second return on pump or is this a good excuse to justify a MIG welder : ) ? Been wanting a MIG welder forever

It was all explained on the pro-touring.com board a while back. I'll try to find it.
