Check all of your connections on the charge piping and also make sure there aren't any leaks pre-turbo.


There was definitely something causing that turbo to spool slow, just couldn't put my finger on it.

def check for boost leaks. that will result in very slow spool time.

internal or external wastegate? maybe it's leaking?

CoreyR

sounds like pre turbo leaks. check to make sure the wastegate is hanging open and that your turbo&gt;manifold gasket isnt leaking. ive had similar problems.

EKlscoupe_98

got some new couplers and clamps for the ic piping. also noticed that it looks like the wastegate was leaking on the backside going to oreder some new gaskets. hopefully that was my problem i keep this updated thanks for the help so far

CoreyR

you would be suprised how much a small exhaust leak will affect spool. if its leaking pre-wastegte thats very likely the problem

EKlscoupe_98

new gaskets in no leaks now but still slow spool

young noob

does it spool any faster? how big is your exhaust, or small rather..........

young noob

didnt catch the 2.5 exhaust at first, only thought that was downpipe on maybe stock exhaust.....how much boost are you running on the spring on the wastegate? and how much shows on the boost gauge?

da_dude

Go over all your couplers and make sure it's clamp down tight. Check couples for any wear on them. It's a boost leak somewhere. Check your manifold too.

EKlscoupe_98

pulling the manifold checking for cracks going to put a new gasket on. but i keep checking and double checking starting to think its the turbo will post up later if new exhaust manifold gasket doesn't work.

okay made one of these the flang for the bov is leaking pretty good around it. couldn't even build 1 psi with it leaking using a bike pump.

Found your problem.

EKlscoupe_98

lets see i'm still spooling late i've haven't been driving due too i want to get all the leaks taken care of. so far the the places i found leaks are the weld around bov, the bov itself, my iat sensor, a hole in one of the couplers.

lakai_19

your intercoolermight have aleak in it

batboyvaj

you need something to pump air a little quicker to find you leak. try to get a air compressor to pump air in faster to help find your leak

EKlscoupe_98

going to get a portable air tank tomorrow sometime. i'm going to find them all idc what it takes.

ITS_Dunn

With all those leaks you're almost just as well off to start it all over again

Keep on them and that is your problem for sure. You should see full boost on that thing by 5500 or less by the end of it.
