my completely stock CA ran 7psi, all day long. Well, till about 7grand, and then it would start to taper off. Stupid hairdryer...

i just assume that all turbo vehicles run about 7psi from the factory. unless its a volvo, those cars are wierd. my mom's 850 turbo runs 19psi in its "sport" setting. gotta love a family sedan with 320bhp, that car flies. its also on its 3rd engine (wonder why? couldnt possibly have to do with the fact that it runs 19 pounds of boost!)

i believe the ca will run anywhere from 5 to 8 pounds from the factory. the turbos are pretty old technology and the actuators are all set a little different. its really a luck of the draw.

and thanks for the link. i never really stray from the ca forum though. i like it here, the other forums are big and scary. i like knowing everyone's names.

mines never boosted lower than 12 since i've had it. i'm thinking its the combonation of a 3" exhaust and a free flowing IC setup.

maybe something is sticking... strange that it would be boosting that high. maybe one of the lines to the wastegate is pinched or something...

Volvos have some wierd stuff - you could have bought a low pressure turbo, a high pressure turbo and a T5 (max power, yet low pressure) 750.

FYI : DSM's run 11.5psi from the factory Evo's run between 11 and 19psi depedning on RPM (wierd variable setting)

The manual says the actuator is 786 - 840 mbar.

So in real money is...11.397 - 12.18psi.

This probably translates to about 9-10psi at the plenum by the time it's gone through ****ty stock WMIC.

wow. that high? theres no way because the boost cut is at 13psi on a stock ca18det. well, any way you look at it most of these ca's run about 6-8psi when they come from jap land.

81na ZX, the volvos always come in 3 turbo models as you listed above. the reason the boost in my mom's is so high is that it has a chipped ecu for 320hp, 300lb/ft. and i know there are variations in boost for about every car, but since i really only deal with nissans 7 seems to be an accurate magic number.

LOL!

i guess I linked the wrong site along with the other 10 pages i have tabbed in my firefox

R34 GTR, the boost cut is a bit of a myth as it's not a boost cut as such, it's mass of air cut.

so on a hot day it might be 16psi, on a bloody cold day it might be 12psi.I would get fuel cut @12psi when I had an S14 SR T28 on the car during winter.

But even that depends on what mods you have etc, a very good FMIC, exhaust etc that helps everything flow better will lower that psi figure.

boost cut? i dynoed my car, and turned the boost all the way up to 18 psi, only problem i ran into was blowing my intercooler piping off. yes its a little much, but im running a sr T25 and an upgraded sidemount, but i made 200 rwhp. i never saw a boost cut though.

The ECU cuts the fuel when the AFM meter reading hit's a certain voltage, IIRC it's something like 4.8volts.This is basically what FCD's do, they just regulate the voltage signal so it never goes above this figure, so the ECU never cuts the fuel.

Fuel cut is great if you ever experience it LOL, you know it's happened as your head bounces off the steering wheel.
