Hello all,

As you can see from my signature i will soon be the proud owner of a sweet 92 Legacy SS.....more on that later.....i will be driving from denver to portland, OR which is rougly 1300 miles....so needless to say i want to save on gas. It has a boost controller and was wondering are there any ill effects to turning the boost all the way down? will i get better mileage?? thanks guys

Cory

Depending on the boost controller (Most of them are simple Manual ones) you cannot adjust the boost BELOW stock levels. You'll save gas if you adjust it down, but it wont run any better than it would stock.

Also, I can't think of anything bad happening if you adjust the boost all the way down.

Running very low boost will just cut your power as expected. And if you have almost no boost on a 8.5:1 CR engine, you will be dog slow. But you won't damage anything. Knock yourself out.

Got yourself a T-leg huh Cory, very cool. Stock boost is 8-9 psi I believe. So whats your plan? Is this a driver or is the Imp getting a EJ22T soon?

Gary

BTW, My '92 4EAT gets about 26mpg freeway 70-80mph, if your's in a 5MT it should do a bit better (my '91 5MT still needs a new clutch so no mpg numbers yet).
