Master cylinder/engine compartment space

[nicks93kblazer]

Hi everybody, I mostly just read the news here but I finally have a question of my own:

I'm planning on building some shocktowers that will come clear up into my engine compartment much like those in the 3-link technical article but tubular design so rather than more straight up and down with a plate tower, my tubular hoops will need a little more room. unfortunately my master cylinder takes up some of this space and I was wondering what would be the best way to overcome the problem?

Here are my thoughts:
-find a master cyl thats more compact? what would work?
-make a wedge against the firewall to point the whole booster and master towards the engine? this may not give enough clearance, but with a smaller master would maybe work.
-switch over to hydroboost and do it that way. seems like a lot of work?

This is all being done as part of a solid axle conversion on a '93 fullsize blazer. any help is appreciated!

thanks-nick

Well, changing the angle of the booster would be A Bad Thing as it would screw up the mechanical relationship of the brake pedal to the booster... the lever in there wants to move in one plane, not two, right?

Hydroboost woulda been my suggestion, as while it's extra plumbing, it is SOOO much smaller than the vacuum booster.

Changing masters is a tricky business and one I am not fond of, having done a considerable amount of it myself. I strongly advise keeping a master that matches your application and booster type (vacuum or hydro.)

I agree that you shouldn't angle the master cylinder.

What shocks towers are you building that are that high up and that far back? I'm having trouble imagining a setup that would need to mount coilovers/shocks that high up.

thanks for the help guys. sounds like hydroboost is probably the way to go even with the extra trouble. I got some used 14" stroke coilovers I'll be running. Not sure how much travel I'll be squeezing out of them but I'm trying to mount them high enough so I dont sit higher than I want to and keep CG as low as I can. I'm aiming for 8in lift to clear 38.5s or 37s. I'm considering just going to coil springs though. As far as strength goes what are your opinions about running a tall narrow tower with a sharp bend as compared to one with a less dramatic bend and a little more room to stretch its legs? This would probably be with 1 1/2" dom and use a support running from tower to tower over the motor. Ill try and post some pics within the next day or two of what I'm workin with (or against).

thanks again,
