how do I raise the boost level?

[Fenvy]

s14 t28 turbo, blitz sbc id, the usual stuff

when I set it to 15 psi, seems like it never want to go pass 10, I checked all the setting on the boost controler and I can't quite figure it out what else I'm missing

is it just slow spool for a stock turbo? or am I missing something?

[st33f]

sounds like your sbc isnt hooked up right, or your turbo wont make more than 10 - is it old?

i mean my t25 makes a stable 11-12 no movin around, but it'll make 18 spiking if i try... is it a s14 motor?

[Fenvy]

s13 motor with s14 turbo

it should* be right, if I set it to 8 or 9psi it'll be capped at the level

would lack of tuning have anything to do with it? untuned power fc w/ bigger injectors, z32 maf

what BOV u got? many leak the wa they come from factory

you prolly wanna tighten it up... also u running blowthrough or not?

[Fenvy]

hks ssqv unadjustable vent to atmosphere

wastegate leaking, or opening at 10psi?

[st33f]

im pretty sure its adjustable... ill look at the ole sucker when i get home tho- its got a bolt on the back...

i had one on my old car... now i use a type-s because my hotpipe for the hks got bent.

the wastegate opens when the boost goes up--if the boost is being regulated by the sbc, either the sbc aint workin or the actuator is fux'd

you dont run blowthrough i take it? If not do you recirc withthe HKS?

[Fenvy]

I USED to recirculate it but I don't really like it. No gas milage increment like some claimes so I took it off. That didn't allow me to run higher boost either way.

[st33f]

right-- i think its one of 3 things..1.bov leaks2.boost leak3. somethings wrong in boost controller...

it still makes boost hard to 10 psi right?and u can hear it grumble when wastegate opens?

[SimpleEnigma]

Have you checked your IC piping/BOV for leaks under boost? Also, try checking the wastegate actuator hose for a vacuum leak. Had that prob with a friends Z31 Turbo. Unless your SBC also monitors your AFRs i dont see how it could refuse to increase boost unless its broke.

[Fenvy]

I've NEVER seen my car go past 10psi of boost on the said turbo

I looked through the settings.... auto peak is on, scramble boost is off, warning/limit/set is at 15psi, gain is at 40

allthe hoses looks fine, zip tied or clamped at each end

[st33f]

something leaks dude... or your turbo is beat. how old it the snail?

[Fenvy]

it was from someone elses's from clip from phase 2, I think it was about 50km

I'll check all the hoses again.

By the way, you know how there are 2 inlet for the intake manifold pressure? Well I kind of put everything into one inlet, could that have anything to do with it?

[Fenvy]

oh yeah, I have a setting between acuator and wastegate, I have it on acuator atm, is that correct?
