Anti-surge comp. housing missing anti-surge relief holes

Is it surging?

Or are you just fixing something that isn't broken?

I'll take "B" for $500 Ian.

Even if it wasn't ported, wouldn't the irregular shape of those ridges inside the housing still help to disrupt a bouncing air pressure surge wave? Kind of like baffling in a muffler, which is designed to be less reflective to reduce sound pressure waves.

 

[Doward]

Nope, because the pressure wave, IIRC, comes off the tip of the inducer.

BTW, tubbie, I answered your question in the Turbo forum

It isn't broken.

I am just interested to see if it will work to add this to it.

We're calling garrett in the morning.

 

[blackout_89t]

It is not morning anymore, any answer?

 

[MK3Brent]

Oh, lemme call CJ... see if he called them.

I'm in Greenville for the weekend.

 

[MK3Brent]

Nope... they weren't open

Maybe monday.

 

[MK3Brent]

CJ called Precision, and they said the GT42 and GT4088 ported shrouds were the same style... didn't ask about the holes though.

Didn't think they really knew though.

 

[williamb82]

my gt4082 has the antisurge slots.

 

[blackout_89t]

Hmm, the "ported shroud" is just a machined slot? I always thought it was small holes.
