are u supposed to hear an induction noise at idle?
this is sort of a random question..
while my car idles I can hear the engine "sucking" the car sat for a long time with a blown motor.. before i gathered the funds,time and motivation to overhaul it.. (1.5yrs approx) ever since it ran again.. it has had this sound.. i don't know if it's supposed to do that or not.. when u turn of the car.. u hear the sucking noise for a little longer after the engine stops as the vacuume equalizes or it might be a vacuume leak? rellevant mods: the car has stock IC.. but has the HKS hard pipes (maybe this causes the echo?) and twin apexi filters, rich mans non-seq. the car only boosts 7psi.. but it holds it.. I don't know if that's the lack of restrictor pill or the result of a boost leak.. Anybody have similar sounds? |
More than likely your hearing the fuel injectors.
|
it's not a clicking sound tho..
it's the sound u hear when u put ur ear near a mushroom filter/hard intake on a honda with a B motor.. |
Could it be the impellers spinning down after shut off?
|
if it was a HKS T51R i might agree..
but I doubt the stockers spin very long at all.. i'm just asking if u guys hear your motors "suck" air at idle.. |
Do you still have an air pump?
|
nope.. long gone..
good idea tho |
Disconnect the TB elbow. Then listen to hear where the sound is coming from. If its by the turbos it could be a damaged blade, if it's coming from the tb it could be a leak on the compression "stroke."
|
u mean remove the Elbow from the TB side so the TB's are out in the open?

V-Ton's got a valid idea too. You could also be hearing some sort of coolant movement or air up by the TB. Anyway, if the car's running fine besides the boosting problem I would do a compression check. If the compression check goes well then do a champagne test. When you pass both of those GO SINGLE. You'll spend more money and time on the twins than with a single.
