All good mate. I’m just picky lol.

I expect the same towards me. Thank fuck you went black. Link to the stainless clamps?

Yea no worries, its just so easy to get carried away that’s all.  I’m picky too, I see it, I just have the satisfaction of hitting the loud pedal, then I sort of forget all the imperfections

I used thes;

So entered into the “Holden’s back Home” show and shine / display at Peter Page Holden at Elizabeth on the 24th September.  They have over 100 Holdens so far, so should be a bit of fun.  They are apparently organizing a cruise afterwards up Phillip Highway and through the actual Holden factory which is pretty cool.

what brake booster/master cylinder do you have in this?

VT. Race brakes.

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

both the booster and master? so it modified to suit the VR ?

reason i ask is  my VS has a VT Brake upgrade on the front and since getting the my VS back on the road, the few times i have driven it the pedal feels a touch more spongy. It was fine before with the old v8 but just not sure if its the fact that i havent driven it in a few years and my VY Berlina has a HBD Brake package (slightly bigger calipers and rotors than standard) and i havent driven much else recently

both car have braided lines instead of rubber hoses

my VS still has the standard booster/master and never had a spongy pedal before

Yea mate, its a VT fast fill master and booster.  I bought it as a “package” including the modified mount bracket so it bolts straight up.  Sounds like its the size of the master bore, do you know what it is?  If you have larger brakes then basically it takes more volume of fluid to flow to apply them.  If you have the original size master cylinder bore then to get more oil volume to flow means the travel for the pedal has to be longer if that makes sense.

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

Yeah makes sense, No idea what the stock one is, just the standard VS booster and master

Do you have a link to a website, I’m almost tempted to get a s/hand unit and mod it myself

Its pretty easy to mod it yourself, google it, pretty sure there instructions on a couple of forums.  For me it was just one less thing to build/make/modify.  This is their website, actually they are looking at becoming a forum sponsor so if you call them tell them you got onto them through us

Very nice car. Have sat and read the complete build thread.

 

Also exec24 without wanting to take up much of this build thread. I have just finished the mods to suit Vt master using vs booster. Which going off the instructions from calais turbo forums was very helpful but basically its as below.
<p style=”text-align: left;”>Unbolt the master. You then remove the bolt out of the master cylinder side of the booster which would sit in the back of the master cylinder. Cut the head off it Then put a slit in the end so you can screw it back in with a bit of locktite (otherwise could collapse the inside with nothing in the center)</p>
Master bolts on and you use the vs reservoir with a small new hole to drill and tap. Bend the brake lines to reach.

id much rather replace the whole booster/master to the VT setup, i’ve been checking out a few other forums seen a few ways people have done it

So one hybrid semi-legal catch can set up completed.  Its been something I have wanted to finish off for a while.  So to be fully street legal the crankcase vent system has to be closed loop, i.e. plumbed back into the inlet so it gets consumed by the engine.  The trouble is all engines breath, especially 454 cubes at 7,000 rpm, and what happens then is the engine simply isn’t pulling enough vacuum and isn’t able to consume all the vapors.  Anyone who has spent anytime on a dyno knows wiring the dipstick in when doing full power runs with a closed loop system is common as the pressure in the crankcase pushes the dipstick out.  Obviously wired shut and with prolonged use like on a burn out pad or drags you risk blowing seals and also losing power.

On the LSx454 there are 3 ports, I think its a little different to a regular LS set up.  There two smaller ones on each rocker cover and one gutsy one in the valley cover.  So what I have come up with is an Elite catch can plumbed to each rocker cover, and through a non return valve to the inlet vac manifold. Then I have added a regular style vented catch can.  I have mounted it under the drivers front guard tucked up neatly out of the way.  This I have again plumbed through a non return valve to the valley main breather port.

The idea is for regular driving the Elite can will take care of business, but under a bit of welly, when the closed loop system cant keep up the crankcase can vent to the normal catch can under the guard.

Its not strictly legal, and if I were to ever get pinged for it, it would be pretty easy to plumb the valley to the Elite can.  Or I guess I could have a simple shut off valve that when I get to the track i open up.  Anyhow its one of those jobs i have been meaning to do for a while.

Couple of pics, apologies its hard place to take a decent pic of.

Nice very clean spot for the can too.

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Get rid of the one way valves IMO. Air will want to enter the engine also to stabilise pressures.

My VZ had passenger side rocker blocked.

Drivers rocker to catch can with the out let going to pre tb, into intake tube.

Valley went to post tb

NONE of that works with an 8ITB set up.  That’s why I have had to be creative

LOL, ^^^^ life is a little harder when you don’t have a common plenum as a nice source of vacuum for a regular PCV system.  Such hardships you have to deal with…..
