Hey guys and gals. Just had a quick question. Is my supercharger boosting when it is at and below "0". Thanks in advance.

Boost is above 0. You must not have it hooked up right or something is wrong if it isnt going above 0

no it goes above the "0" but i was just wondering cause gas prices are getting high and i want to save on my gas bill. Do you know if i keep it below "0" will my gas not go down as quick?

If you are that worried about it, you shouldnt have a supercharger. lol Better give it to me so you dont spend so much on gas.

...or a 4Runner for that matter. Superchargers are parasitic, so they are causing additional strain on your engine 100% of the time.

Try and stay out of the boost, watch where the boost goes up, and try to stay as low as you can in it, but still have enough power to drive around, so don't lug the engine.

In my old vw gti, i got better gas mileage keeping it in the lower boost pressure and got better mpg.

More air=more fuel delivered through the injectors=more horsepower. A supercharger can actually improve economy if driven reasonably. Less skinny pedal and smoother acceleration keeping it out of boost unless you need it...Unfortunately, though, you have to run Premium fuel which costs more. Tuning your engine will help a lot also. Back to the question... your engine will only develop boost under certain conditions-throttle, load, etc. at idle or normal cruising it should almost always be pulling a vacuum.
