i am again happy to report that the second misting unit is in place, this time an improved one installed in my wife's car. specs are as follows :
vehicle second unit is installed in : volkswagen rabbit, 1981, 1.7 l direct mechanical fuel injected engine. aprox 150.000 k on it. in good running shape, wife uses it every day for her trips around town. modifications from first unit : smaller container (1 l vs. 2 l); stiff container, with only one wide mouth lid held by a hinge and clasp design, much like a tool-box; no valve, direct from canister to vacuum. entry point into induction system : right next to the power brake vacuum hose, very close to the intake manifold. results have been similar to the first unit, except perhaps more noticeable because of the larger engine, and the fact that this rabbit only has a four speed gearbox. an added bonus is that wife insisted on an alcohol mix, and as i had none available, i used up some of my grant's scotch whisky. bout same proportions as first unit. for the first few minutes the thing smelt like a bloody refinery. settled down to lower smell impact from there on. but you can still notice the scotch in the air. do not suggest you use this. any cop pulling you over will swear in court that you were stinking drunk. vacuum in the canister is such that the lid cannot be opened while in operation. it bubbles viciously away ! acceleration is improved. low end performance is much improved. low end knocking/vibration disappeared, even under severe driving conditions (doing a 360 in a roundabout in third gear at 45 kph !) summing up, wife now claims she has what amounts to an auto tranny car. note : as vacuum drops at higher engine rpm, knocking becomes noticeable again. next step : plan on installing a separate vacuum pump, as used in diesel powered cars with power brakes, to get vacuum proportional to engine rpm, or at least constant. have a hunch this would be somewhat like using a smog pump, though i'm not really familiar with what that is. vacuum pumps are pulley driven off the cshaft, and just pull a vacuum for the power brake diaphragm. will not run fuel economy tests on this car, 'cause k meter not working. enjoy !
