Hydraboost vs Electric assisted brakes pros/cons Which is better?

[Ls2GS]

After recently getting my GS together and running I have come to realize that my engine just doesnt make the vacuum I need to stop the car well. I was considering an upgrade to hydaboost or an electric assist. The problem is that I do not know alot about either one or the direction on what to use if I did decide. Any suggestions would be great, and opinions of both.
I have a 69 GS with a Wagner built 415 ls3, T56 magnum, currie 12 bolt with 4.10s, full UMI suspension, and a complete Right Stuff 4 wheel disc brake conversion with the fancy rotors and calipers (Not Impressed with the stopping power considering how fast this car is!). I want to keep the factory 15" rally rims to keep the stock "Grandpas Buick" look.
Thanks for the help in advance!

I had the same problem with my modified '61 Bel Air. At the time CPP was the distributor. Unfortunately, they sent me a unit for a small block which hit the valve covers. I was anxious to get my car on the road and despite the mistake being on CPPs end they wanted me to go back in the queue and wait another 4 weeks. I called Paul directly and he personally had a big block setup made that night and and I had it in 2 days. Once in, it worked great but calling it a little noisy would be an understatement. Paul stepped up again with expert advise and a new reservoir to reduce foaming and a reducing fitting to lower the pressure output of the new PS pump and it has been perfect. Great product service above and beyond. This is a vendor you can count on.

That Hydratech set up looks like the way to go! I would like to hear about the electric brake assist though.

Hydratech all the way, its the only hydro assist unit i will sell!

I will be a voice for the electric system.

The main reason for me going with electric was space. I didn't have the room for the hydraboost due to its length and my turbos. A major pro with the ABS electric system is it's the same size as a manual tandem master.

So far I haven't had any major cons with it. I am very happy with the performance and feel of the brake pedal.

A minor con would be mounting and noise of a hyd pump and accumulator. (but this is mostly based on how and where you mount)

What system did you go with Ron? I'm getting tired of these manual brakes on mine.

Will need to put your pedal ratio to 4:1.

A recent story with my electric brakes and tire change..

I was running Toyo R888's (285/30/18 front & 335/30/18 rear) with Wilwood 13" rotors/SL6's in front & 12" rotors/Dynalite's rear. Pads are BP-20's around. Even though the car is 4000lbs with me in it, it stops incredibly well. Not touchy at all on the pedal, but when you get into it, Blow Fish on the windshield!

So, I took off the Toyo's due to low tread and in place put my older Mich Pilot Sports (275/35/18, 335/30/18's) which I will use for RTTC event.....All I can say is WOOOH...these babies are much slicker then the completely old and warn Toyo's. I will need to get use to that—can lock them up much sooner. I will try the BP-10’s and “E” pads I have on my bench to see if that helps tame it down a fuzz with a little less Cf.

One of these day I need to do 60-0 measurement.

Thanks! I'm trying to figure out my manual brakes. It should be a pretty decent setup, but it doesn't stop worth a darn. I have a 6.25:1 wilwood pedal assembly with dual MC's (.7rear and .75front) and I still can't lock the brakes up. I put Hawk blue pads on it and it helped, but I can't deal with the dust the crappy cold braking so I'm going to take them off.

It's not looking like the electric brake setup will fit with my dual MC assembly.

I like the clean look the system would provide (if the pump was mounted out of place), if the electric pump fails do the brakes fail completely?

Just asking from a safety perspective.

Did you guys see the ECI universal brake assist? That seems like a great alternative, too bad it won't fit under my dash.

When I ran a manual set up, I was up to 8:1 pedal ratio to make work with the .75 masters. Then pad knock back became an issue on the rear 9". Couldn't deal with the double brake pedal pump during hard cornering. Noticed it more as the master bore gets smaller with big calipers.

You will always have brakes, just may not be to the full power. With the accumulator, you can slowly feel the brakes going away if the pump stops working as it holds pressure for additional stops. After the pressure is gone, you can still drive cautiously with brakes like a vacuum booster without vacuum.

im a hyrdaboost guy.. but they do take up a bit of room, and as stated problems with turbo piping and what not. but you cant beat the pedal!

[Rebeca_Lynn]

Is there a hydro-boost option for dual master cylinder set ups?

If there is it may be a nice option for my build instead of manual brakes.

With the hydro-boost system how big or small can the power steering pump be, as I have EPAS system and will not need the pump with out running hydro-boost.

Pics speak a 1000 words, right?

Hydratech systems now available with CNC 1 1/16" balance bar MC's on a special order basis.

GM A/F Body System shown with CNC MC package # 244

Same overall length as a system installed with a C3 Vette MC!

More on this here: http://www.lateral-g.net/forums/showthread.php4?t=36692

These types of systems can be run stand alone (without actual power steering) - any pump arrangement will power it up.

Cool thanks for the quick answer.

[INTMD8]

Just thinking out loud here, but if there was any way to run the balance bar masters directly -above- the Hydratech assist unit via bellcrank I would be all over it.

Seems like it would be possible to do this and end up with a very compact setup.
