Rb20det

[Black Widow]

Hey peeps i've got an r32 gtst with an rb20det. When i go to put my foot on it, it starts to spool but it also sounds like its leaking boost from somewhere as there's like a "pshhhhhh" noise and it seems like there's a little lack of power. Has anyone else experienced this or know what it could be?

what boost is displayed on your boost gauge?

do you know what a turbo sounds like?

11psi. which is what its set to. yeah this is a really loud shhhhh noise tho..doesn't sound like a spool unless i'm on crack and have got it completely mistaken..but it feels like i lose power

Do you have a pod filter by any chance?

yeah i do. Apexi

sounds like induction noise. Put an airbox on and see if it makes a difference.

If you can see 11psi, then "if" there is a leak, it is after the turbo.

so being an RB, most probably a gasket leak at the turbo manifold.

My guess from this side of the monitor is that you have a bolt missing from the turbo to the manifold.

you might be able to just tighten replace and tighten it and it will go for a while longer.

"IF" there is a manifold leak, and you leave it, it will get worse as the whole in the gasket gets bigger.

eventually, it will start to sound like a lawn mower when idling.

"OR" you are most likely on crack and it's just the sound of an RB20 with exposed pod filter.

ok cool. i'll have a look. I think everyone may be right i think it is probably only the pod induction. I was just wanting to make sure because i'm selling it..i'm not the most technical minded person and sometimes i can be a bit thick

the lack of power is probably just because it is an rb20.

the noise is probably just induction noise.

if there was a leak in the exhaust manifold you sometimes hear the exhaust gasket ticking as it moves.
