Brake Survo Pipe With Throttle Bodies

[nova 2L 16V]

I Have Just Bought A Set Of Direct To Head Throttl Bodies And Im Now Wondering What To Do With The Brake Survo Pipe Any Ideas?

[Adam]

Are there any unions on them for a vacuum take off?

unions?

[Adam]

Threaded thing, to fit a brake servo pipe to.

If not, just get someone to drill and tap no4 body after the throttle plate, and fit the pipe to that

direct to head throttle bodys ? fkinell.. sounds prety hardcore

If you tap two of the bodies doesn't this reduce any 'pulsing' through the brake pedal?

Not that I've heard, 1 is a more thorough method than the other I guess, if you can be bothered.

LiquidPug is half correct, it does reduce pulsating of the servo return pipework. However nothing is felt through the pedals.

Drilling into two of the bodies reduces this as they breathe at exactly opposite times, as per SBD instructions, I've had my drilled in between bodies two and three.

SBD give the reason that only drilling into one body, gives the very very slight risk of running out of braking vacuum, as it only breathes on piston strokes, so with having opposite stroke bodies being drilled, you have no chance of braking problems.

Thus said, I had direct to head bodies on my white Nova, and this only had one outlet on the side of body#4 with no problems, but now getting serious in all aspects of track driving, I'm happy my new bodies have 2 take offs.

Hope this helps

LiquidPug is half correct
