boost on fd

[jukesr]

hi peeps i am just wondaring watt the boost is on standerd set up fd.
i am geting 0.55 KG/CM2 is this ok or is it low thanks:Thumbs-up

Standard boost pattern IIRC is 10-8-10 (Psi) for pre 99 turbo\'s
 
In kg/cm2 this is about 0.7 - 0.56 - 0.7
 
So it would appear you are not achieving full boost to be honest.... Check all the intercooler connections and hoses before delving deeper as these are usually the concern.....
 
Does it stay solid at 0.55

Quality of the boost gauge and where it is plumbed in is also a factor.

yes i put my footdown and the boost gage go\'s to 0.55 and stays there even wen 2rd terbo kics in. :Hammer
and wot do u mean wen u say 0.7 0.56 0.7 thanks m8.

i have a blitz boost gage direct link to (IM) is that ok.

boost pattern on FD\'s goes something like (in psi cos i\'m used to it)
 
First Turbo spools up to around 3500-4000 and should be 10psi
 
Second turbo starts to spool up around 4000-4500 and there would be a drop in
pressure to around 8psi
 
Second turbo at full boost til redline ish at 10psi
 
The first turbo has to achieve a set pressure to bring the second turbo in and there is a slight dip in pressure due to the 2nd turbo spooling up...
 
Or something like that anyway...
 
Yeah that sounds fine, normal way of doing it....  Have you got an Apexi PFC and Commander ?

[jukesr]

no i do not have a APFC i am looking at geting one. but hard to fined for 92 fd :rolleyes:
