i can't get the car to boost in neutral... also during regular cruising and when im @ idle... should the boost gauge read vacuum?

 

boost is load based, so when you're stopped and reving the engine boost will not build. and yes you should read vacuum when just cruising.

 

get anti-lag or a 2step for launching if u want taht

antilag will burn ur turbo up though

 

yes, its beacuse the pistons are sucking air in at that point.
At a certian rpm the supercharger will provide more air than the pistons can suck in thus pressure(boost) is formed

 

sweet, so everything is normal~ i saw a Turbonetics video where the guy is parked and he's revving and blowing off... and a lot of other turbo cars can sit still and spool so i thought they're something wrong =)

but thanks for clearling that up... also the shop forgot to install my one step colder spark plugs... is it BAD to drive without them for a weekend?

 

so if its not boosting when cruising or idle, does that mean gas mileage doesnt suffer unless you slam on the gas? If so.. that's sweet.

 

it feels stock until about 3200rpm. when i rev in neutral (either parked or cruising) the gauge goes from vacuum to 0 psi but no more than that...

 

Right - It should do that.

Cheers Amy -

Er - Think about it...

 

With the car in neutral free standing revving should get you little to no boost pressure. Under load while driving the car in lets say 3rd gear at around 2800 it should cross from vacuum to boost and about 3200-3500 you should be getting 8-9 PSI

 

EXACTLY. This is yet another reason turbos > super chargers

 

actually that has nothing to do with it. it only takes a certain amount of hp to make your car travel a certain speed, like say 60mph. if the a/f ratio is the same across the board (n/a, supercharged, turboed) all will only be using the same amount of fuel to make that certain amount of hp, theoretically. in some cases though you can actually gain freeway mpg w/ f/i. once you dig your foot in it though, it all goes to hell with f/i, hahahha.
