Oldiesel Posted January 28, 2013 Share Posted January 28, 2013 I expect to be installing cruise control on an 87 Toyota MH with the 22re sometime soon.Since this little engine is going to be working hard even on level ground will it develop enough vacuum on a moderate hill for the cruise to continue to function.I have a complete vacuum type aftermarket kit laying around,but if its not going to be functional maybe i should spring for the all electronic type $$$ Anyone with experience with a vacuum operated system? Your input would be apreciated ! Don Quote Link to comment Share on other sites More sharing options...
WME Posted January 28, 2013 Share Posted January 28, 2013 Had a vacuum type at my altitude (5400 ft) max speed was 50mph, anything faster and the manifold vacuum would drop. Quote Link to comment Share on other sites More sharing options...
waiter Posted January 28, 2013 Share Posted January 28, 2013 I think your going to need to spring for the electric servo. My throttle spends a lot of time on the floor.John Mc 88 Dolphin 4 Auto Quote Link to comment Share on other sites More sharing options...

Your input would be apreciated ! Don No gas engine makes vacuum all the time and most diesels never make it. Thus the reason on gas engines with vacuum operated features to have a big vacuum reservoir. Just about any car has one. Cheap new and even cheaper in the junkyard. Often just a big plastic ball with a mount attached. Your Toyota engine will make plenty of vacuum off and on. You just need a reservoir to store it so when needed, it is always there. Now if you plan on driving a hundred miles with the pedal to the floor the entire way - there MIGHT be an issue. There are also small electric vacuum pumps available but I doubt you need one. Just about all diesels cars and trucks have mechanically driven vacuum pumps. That because 99% of all diesels run wide-open air intakes all the time and thus can't hold much vacuum. http://store01.prostores.com/servlet/vwparts4sale/the-26126/LH-Vacuum-Reservoir-Tank/Detail http://www.ebay.com/itm/Vacuum-Reservoir-Tank-VW-Passat-98-01-B5-/310050718800#vi-content http://www.google.com/imgres?imgurl=http://i00.i.aliimg.com/photo/v0/615227292/vacuum_reservoir_tank_with_check_valve.jpg&imgrefurl=http://midcool.en.alibaba.com/product/615227292-212266293/vacuum_reservoir_tank_with_check_valve.html&h=540&w=540&sz=62&tbnid=fGgnI6F-GqfhkM:&tbnh=90&tbnw=90&prev=/search%3Fq%3Dvacuum%2Breservoir%2Btank%26tbm%3Disch%26tbo%3Du&zoom=1&q=vacuum+reservoir+tank&usg=__Qh7e_61K0Wbj6QDz_sVSU23pkzs=&docid=j1ymo1gSuYDJbM&itg=1&sa=X&ei=qIUGUaOWN6nI0QGg7YEQ&ved=0CEcQ9QEwAw&dur=188 Quote Link to comment Share on other sites More sharing options...
