What motor? I just removed all but 3 vacuum lines. My PCV valve, brake booster, and vacuum advance to the distributor. Runs better than ever!

Plugged them all with pipe plugs.

Seriously... just don't disconnect the one going to your brake booster

May I ask what is your motivation behind this? Thanks

Well atleast from what I've herd big mike no vacuum lines and smog stuff means more power and I need to push as much power as I can with my 22re and I'm running low on money

The amount of power gained from this will be minimal. I can only think of two candidates to gain a trace amount of power: 1) cooler and less oil-contaminated intake charge by removing the crankcase ventilation system (PCV), and 2) cooler intake charge by disabling the exhaust gas recirculation system (EGR). If you remove vacuum solenoids, you will reduce the load on the charging system (by fractions of fractions), however the power benefit in this case will probably be attributed to a weight reduction (on the magnitude of grams).

You could also remove the throttle body heating circuit (by installing a valve in either of the two throttle body water hoses) to reduce the temperature of your throttle body, intake manifold, and related components, however you'll always have a high idle as a result (so I advise you use a valve and leave it barely cracked open to let a trace amount of hot water to the throttle body idle control circuit). But this is no vacuum line.

I think you'd be better driving around town with half a tank of gas or less to reduce the weight of your truck, or remove your passenger seat, or the junk in your glove box, or start a Subway diet, as you'd probably benefit more from this and will not sacrifice the dependability of your engine [ie. the EGR system reduces stresses in each cylinder by reducing the average cylinder temperature, and the PCV system helps maintain cylinder compression by 1) increasing the life expectancy of the previous valve job by lubricating intake valves & seats and 2) minimizing piston ring to cylinder wear].

thanks big mike and i also removed them cuz i didnt want to deal with putting them in

BigMike · « **Reply #11 on:** May 10, 2012, 04:08:12 PM »

Sounds good

In my opinion not wanting to deal with them is more of an incentive to have them removed rather than looking for additional power.

Good points, Mike. I removed mine for simplicity sake. Vacuum advance and brake booster are my only 2.

yea ive decided to keep my power steering pump ones and the brake ones
