turbo isn't spooling
 

I got over my fear today and went for a spin in my lscrx with a custom turbo kit. I was not making any boost and i can't hear the turbo spool at all, what can i check for?

Re:turbo isn't spooling
 

do you even have a boost gauge.

what turbo?

WG hooked up properly?

Re:turbo isn't spooling
 

yes, i do have a gauge and boost won't go pass 2 psi, it's a garret to4e a/r 50. I don't know if it's a boost like, my vacumm reading is at 20 hmg at idle.
set up:
450 injectors with safc and walboro.

Re:turbo isn't spooling
 

holy ---- a T4!?!?! if its that big ass mofo maybe you just dont have enough exhaust to spool that baby! check wastegate and any vacuum/pipe leaks...

Re:turbo isn't spooling
 

well he said a/r is 50... I assume he meant .50 hehe,
thats not that big at all.

but yeah, check ur wastegate man,
is it internally wastegated? adjustable?

check the flapper, make sure it can open/close ok.

maybe your boost is set too low,
if its internally WG, and ur boost is set really low,
then the lower ur set it, the longer it'll take to build boost so maybe its set at like 4, and it just cant build in time to reach that 4.

it is spooling though, if ur seeing 2psi,
if it wasnt spoolin you wouldnt see anything.

Re:turbo isn't spooling
 

it's a t3/t40e with .50 AR, my bad.
wastegate will open at 7psi, i already test it. It's is an external wg by the way. it will get 1 or 2 psi at 6000+rpm, that's definitely not normal.

Re:turbo isn't spooling
 

DOH!!!!

Re:turbo isn't spooling
 

It's external. :P

Does the turbo spin freely? Have you checked the pipes/connections? Any leaks?

i wate to make a dumb guess..
u did not un-do the hose that connects the valve cover to the intake pipe. :P

Re:turbo isn't spooling
 

what is the ar on the exh side?

Re:turbo isn't spooling
 

.50

Re:turbo isn't spooling
 

i thought he meant 50 ar on the comp side

Re:turbo isn't spooling
 

t3/t04e doesnt even come in a .50 a/r

its .48 with usually a 50 trim compressor wheel

Re:turbo isn't spooling
 

what you just described is .48 a/r not 50

heres a 50 a/r

Re:turbo isn't spooling
 

actually my does look like that, and it says A/R .50 on the comp housing, so i thought it was an .50. Right now i'm thinking it's the pipes, so i'll check that.
