hi just a quick one

manual boost controller?? worth it or not??


if i fit one how much can i adjust too? i have a psi boost guage and it sits around 15 psi max boost is this good or not i dont have a clue lol sorry boost confuses me lol

 

anyone?

 

15psi is just over 1 bar.
What year car do you have as different versions have varying boost and fuel cut levels

 

They are good, but be careful, check the fueling is ok and not running lean. And don't wind it to much as you will get boost spiking, and you will head butt the windscreen. It is very tempting to wind it more to get more, but as above says there is a fuel cut level. Best to set it when its cold.
All I would say enjoy and be careful.

 

its a wrx 1998 import
whats a fuel cut???
im not to sure what turbo it is as someoen kindly grinded the numbers off for me.... any other way i can find out???

 

Think it will be a TD04 turbo. I have a 98 UK car, and I'm pretty sure the WRX will use the same 'small' turbo.

Fuel cut is a parameter set so that the ECU cuts fuel when the boost creeps above what it regards as a 'safe' level.

Mine did it before I had the car mapped, because the boost was creeping up to about 1.1 bar.


Hope that helps.

 

late model wrxs should have Vf22/vf29 depending on when the car was made (early 98 vf22/late 98 vf29) that's if it's standard but grinding the numbers off seems a bit odd.

 

i have alaways been told to stay away from them wehn i had my skyline and pulsars. always been told there no good

 

my black wrx your right i can just see the nember and its a vf22. is that good?? well i was playing on the way to work and i got the boost needle off the guage and it goes upto 20 psi but sh** myself and turned it right down lol

so what do you guys recomend to set it to for max boost +i mean i dont use it to often to be fair just normally leave it at minimum boost just because i dont do many miles

 

ANY SURGESTIONS??

 

From what ive been told around 14-15 psi should be fine on your car.

 

i would personally take it to a rolling road to make sure eveything is alright then think about messing about BUT i wouldn't use a MBC to raise your boost.

My mate has one of these fitted to his car HDI
Admittedly he does have a forged engine rebuild and runs 1.3 bar it has an inbuilt fcd and raises it in relation to the boost setting.

 

my00 fuel cuts at 1.21bar. 17 psi is 1.17 bar. This is there for safe on my00, i used MBC set at 1.1= 15.95 or 16 psi for 2 yrs befor i removed and had a remap.

 

thats weird as i was playing the other day and i can sit it at 20 psi and its fine goes like a rocket.
obviously dont wanna blow it up so iv taken it off best bet i think.

 

Sorry for the tread hijack but what boost pressure were you able to hold to the redline with a TD04 scoobydoo? Just curious as to what can be done with it, and whether it just starts blowing hot air. The fuel cut being higher on the MY99 and 00 cars means you can get quite a lot of mid range punch but I was wondering whether it will take 16psi to the redline?
