dennis,
can feel the diffrence between 0.9 bar and 1.3bar, not like td04, you dont really feel the diffrence between 0.9 and 1.3bar. let us know, if u can feel the diffrence.

Wing,
like dennis said, wastegate or wastepipe or the exhaust it self, some where might be bocor, who knows.

hey jason, yee sms me, havent reply him yet, will he be staying over night there? or coming back later after that place u mentioned?

no lah,nvr stay over nite.straight away go back to kl after TT in s'ban

thanks guys, how does the manual boost controller works? I tought that by just modifying the wastegate so that it release the pressure when it reach a certain higher pressure say 0.9bar.

If it is just modifying the wasegate, it should be very cheap rite and i should can change it back to stock standard if i want to rite?

I am really low on budget,so hope to achieve higher power without spending much!

the budget way is ppl use aquarium tank valve... whereby its inserted in between the actuator and intercooler piping... u control the boost by opening the valve and shutting the valve... for the desired pressure to reach ur desired boost...

[/b][/quote] izit dat thing oso be called da 'tulang ikan' ah? will da valves loose pressure easily, heard lotsa boost spike problem.

[waikitfire]

it always go 0.1 bar ++ /--
:lol:
use around 5-8 fish tank , if u use one only then sure the boost spike some time 10psi.. sometimes 21 psi... try b4 aready.

wat other ways to gain my hp with out changing the turbo...??

 

[4G93TT]

what is boost spike?

 

[GSR_Freak]

changing cams.

boost spike means over boosting. which may result damage

 

[GreyAero]

guys,

when is the TT for 4G93T? lets make it on next weekend? boleh ah?

 

[GreyAero]

sifus,

i just bought a 2nd hand SARD R2D2 BOV. the problem is, the engine mati after i release throttle from 5k++. why ah? how to cure this?

 

[GSR_Freak]

if you can notice your bov, theres a screw(allen key screw) on top to adjust the spring rate inside, try to adjust it alil bit more tighter meaning harder, most likely thats the case, the spring is too soft, when venting the pressure out, it vented too much air till too much petrol pumped into the combustion chamber and not enough air to burn and the engine stalled.

another reason maybe the travelling piston of the bov is scratched too much, and is leaking, this 1 meaning you can get another bov already.

another alternative is to send your bov to service at a mechanic, hopefully it can be reoiled and stuff like that

just my 2cents

 

[GreyAero]

GSR_Freak,

thanks. i think the previous owner set the spring soft. actually i tried to adjust using the allen key screw. but it was hard tightened. and there is 13mm nut, normal 13mm socket can't even fit in. shit..........

 

[Cheong Mou Kei 4G9XT]

sound like spring setting too soft....no big deal...

adhust is harder n then spray some WD40 into da BOV when u take out da alenkey nut

 

[waikitfire]

change cam..
mat speed?
anyone know any cam for 4g93t?


boost spike is like sometimes u get low boost. sometimes u get super high boost...or when u boosting high high after 1-2 sec the boost drop..UNSTABLE BOOST

 

[GreyAero]

CMK,
thanks. i will try that out.

talking about cam, which profile is suitable for fast street? 268 deg.?

 

[waikitfire]

mostly ppl put max 272... :)!
who is experience about cam stuff?????!!!???????
can tell me abit about the power band?
:rolleyes:

yr bov adjust until too wide aready.. until cause not enough air presure to engine... :lol: thighten it back leh .. :P
more over too wide will cause yr car lose power after boosting. :lol:

 

[GreyAero]

waikit,

i try to adjust the spring harder. but allen key also torn lah. the previous owner screw it too 9 damn tight. somemore there is 1 13mm nut. normal socket can't fit.

272 deg cam? thats garang. u plan to change?
