ps. i can hear the turbo spool but juz not pull like when i 1st got it on.

 

its time to turn up the boost

 

lolz, dude! I know how you feel exactly!

I don't know if im used to the pull.. Or is it my car slowing down? I dont feel the rush any more either!!! WTF?!??!

Am I on the road to think " Once you get fast, you will want to go faster! " Because I cant feel it any more!@ But sure do i Kick lot of asses though.

 

lol. i dont think thats it. i juz got my car boosted on thursday. i know i am not use to it in 1 1/2 days. i know it is something to do with my engine somewhere or somewhere in my setup. any other insight?
thanx

 

maybe plugs are fouled?

 

damn. that might be it. imma check that out tomorrow. thanx man

 

yeah check the plugs... You do get use the power though after awhile, but not in 1 1/2 days...

 

Was it really hot? Because if it was cool one day and really hot the next that makes a very big difference.

Exactly what I was going to say. Drive your car a cool night during this summer and then see if it pulls. You might be getting used

 

Where are you tapped for the boost guage? Maybe it is a boost leak? I highly doubt it though. I would say plugs. What is the setup? I am running 1000cc injectors being fed by an Aeromotive pump, if I stall my car even one time I instantly foul my plugs.

 

check your piping same thing happened to me the silicone coupling was leaking

 

i had a simiar problem and then i saw i blew a wastegate gasket and one off the bolts had backed it self. This caused the turbo to spool alot later adn mad it slow as **** (relative to before)

 

You should hear an exhaust leak if that was the case. . . .

 

m R g S r: i drove it at night in very cool weather.

Kwuaymaikrup: boost showing 10psi so i don't think it is a leak anywhere. my setup it
b16a1
t3/t4 turbo
vafc
dsm 450cc
tial 35mm wastegate
no fmu

SiRiUsWeRkS: my piping seems to be okay. when i had a leak (my 90 degree elbow ripped) i was losing boost. so if i had a leak i would lose boost right?

Mad Chemist: how would i know this happens?(im still a noob sorry)

thanx guys.

look at the bolts that hold on hte wastegate and maybe check hte gasket, a little blue thread lock helped me out

 

well im goin to hope its the plugs!!! if not that would really suck. what am i suppse to gap the plugs to? i forgot it was either 32 or 30 i think. anyone know exactly?

 

.028-.030 is what id do for stock ignition and about 10psi.

also id hate to make this an added possiblilty but when ring lands crack sometimes you wont even notice except for a slightly loss in power. a compression test will tell u for sure tho. couldnt hurt to check

 

if your ring lands cracked...you'd notice smoke coming out of your breather. might want to check for that too...

 

thanx guys no smoke here. so thats good. gonna do plugs after i get off work.

not always true.

check for an exhaust leak, either at the turbo to manifole, or the turbo to downpipe, or wastegate.

well i changed the spark plug. still the same.god i dont know what to do. ***!!!!!!! when i was taking off my friend said there was A LOT of smoke coming out of the exhaust. any suggestions?

 

do a compression test ASAP

 

Do a compression test. You have very poor fuel management, so I am inclined to think you may have melted a piston.

 

bump.

 

have you done a compression test yet?
