Bosch I-Booster: Vacuum booster Replacement

Hey guys, I was curious if any of you have come across using electromechanical boosters in our cars instead of the standard Hydroboost upgrade?

I found a page here for reference where they go into good details on what it might take:
https://www.evcreate.com/ibooster-donor-vehicles/

Here's another link with good info:
https://irate4x4.com/threads/ibooster-electric-brake-booster.394316/

My car currently has an astro-van hydroboost upgrade that has been operating for about 3 years. I love the system, but there are a few draw-backs and I wanted to look into other systems.

I don't like that my system tends to twitch the steering wheel when sudden brake inputs occur (this might be due to an ill functioning accumulator, bit these are notoriously challenging to repair).

I also don't like that my brakes have different pressure requirements than my steering, requiring some fancy hydraulic plumbing to fix. This might be fixable with different master/caliper combos, but I'd prefer to keep my current setup, which is the front/rear calipers and matching master from a 2001 trans am.

Finally, I'd like to try and figure out how to get the power steering pump off of the motor for more possibilities with turbo plumbing.

These are pretty recent additions to the car world, and I didn't see any posts upon initial search. Hopefully we can get some documentation going with this.

Re: Bosch I-Booster: Vacuum booster Replacement

Just finding more useful information.

Here is a thread over on LS1Tech that has some really good information.
https://ls1tech.com/forums/conversio...onality-5.html

Here is a video where someone compares it directly to a hydroboost:

I am really curious how this setup would feel. I am quickly talking myself into buying and mounting one of these for testing.
Now I only need to find a myself an I-Booster from a 2018-2020 Honda Acord. This seems to be something that could fit well. I also like the remote reservoir.

Re: Bosch I-Booster: Vacuum booster Replacement

Hey,
Have any updates on this?
I recently ran into a guy that builds plug and play setups using these same boosters for C10s and other vehicles. He designs the mounting brackets and all the little details to make it a literal bolt in deal but hasnt done one for the thirdgen YET. It got me looking into doing this myself and I am planning on giving it a go with a cheap used setup myself and would love any information you have gathered so far.
Jeremy


p.s as to how it feels, three different gentlemen using his setup in their 60-87 C10s raved about how modern and amazing their braking became so I too am very interested in feeling it for myself.

If you haven't seen it already, SuperfastMatt on Youtube has a video on how to use these in any car. I've been playing around with this idea as well, but I'm slowed down with other priorities...

Re: Bosch I-Booster: Vacuum booster Replacement

Sorry for the late reply, been busy with school.

Thanks for the independent review, I'm now way more curious to try it.

I did actually did see that video by superfastmatt. I was curious about investigating some of the more advanced features of the booster, but It seems that it is quite a lot of work to decode the CAN communications, so I haven't been able to mess with it. There have been some very interesting developments in this direction. Here are a link to that kind of thing:

Other than that, I just haven't had the time.
