Boost Not stable... problem??

[monsterv6]

need some help here on my turbo..seem to be alot of problem and it wont solve....im using a 6a12tt twin turbo..

my boost at 1st gear and 2 gear once u just step on it the boost wont go up to 1 bar...it will onli be 0.7 to 0.8 bar....why...and as the gear goes up the boost will be up but not that stable also...

why i got a boost controllet for blitz sbc2....i hv check no leaks on my piping and etc....actuator maybe??how to check issit spoil or not??

your turbo has reached max efficiency a.k.a maximum oredi.
it's only a TD025, won't push more than 1bar...turbine housing too small.

nah it change already to ihi RH series turbo
from subaru legacy....

max i havent gone yet is just the boost aint stable man...

 

[monsterv6]

any ideas of wat i should check...cause i have check mostly everything...

i think ur actuator but i don't know how to troubleshoot a actuator.:)

 

[monsterv6]

yea i guess is the actuator also.......haihh headache ler....

 

[ftzone]

install an external wastegate should solve that problem

quite easy to rectify this
remove ur boost controller
fix it direct
see if u get stable stock boost
if not then hehehe say buh bye to ur blitz sbc
blitz sbc works on .. arggh i cant get the name into my head
bt it wears as time goes, blitz sbc is ancient, i would point my hands on that

 

[monsterv6]

which stock boosting everything goes find....no problem on that....

 

[scionsigg]

haha den u can take jin advice and throw ur blitz dy haha...should get HKS or apexi mah...more reliable haha

 

[monsterv6]

..nah i dont think the boost controller have the problem..i think is mostly the actuator.......dont la throw away u all damn bad wei hehehe

 

[jinkl]

hehe , could be actuator
bt err , at stock boost, actuator opens fine :) how come ? keke
bt there are other factors , how high r u boosting bro ?
if 1.5 bar , then u get 1.6 or 1.4 at times, its normal

 

[monsterv6]

1 bar is the highest bro....

but sometimes at second gear i straight full the gas is sometimes get .9 bar or .7 bar....
actuator right??
