hi everyone.

i've been reading some posts in this section of carb setups, and anyone ever asked about where do you get the vacuum for the brake booster and for the ignition advance on the distributor.
it's just because when you have a plenum, you'll get the vacuum from there, so, i wondering if the vacuum produced by one cilinder is enough to feed the brake booster or if you need a vacuum pump?
And how do you get the vacuum from carb setups, is it on the intake manifold?

i'll appreciate your answers and if it is possible, some pictures of your project.

tks. :wink:

Hi.

You dont need a vacuum for the ignition advance,but you do need it for the brake booster.
Vacuum from one cylinder is enough,so you only need a small pipe from i think it was 12mm in diameter,and that is welded on the intake manifold.
Just the same size that you have for the hose that is coming frome the brake booster.
I hope thats clear for you?
I dont have some photo's,but i can make them!?

ok! you see, i've been thinking about where to get the vacuum because i thought 1 cilinder wasn't enough... but now its clear!! BTW do you have carbs in your swift (if you have one)?

about the ignition advance, is it possible run with the the stock ECU using the stock ignition system or do i need to change to a conventional system with breaker points and coil?

if you have a carb manifold with no plenum, you should take vacume from all the carbs equally for your brakes.

hmm.. i also thought about take vacuum from all 4 cilinders to make it equal for all. BTW getting vacuum from all 4 cilinders, what would be the best diameter of each pipe??

thank you all, now i get the idea!!
i think this was the topic that was missing for all who is interested in doing carb setups.
maybe someday i'll do a carb setup on my swift... my big problem is the price of cams and cam gears.. where can i get them with a good price??

hey i just talk about cams and gears because only fitting carbs you won't get that much power, you get more torque in your rev band but not max power.. i think you know that
