No more "woosh woosh"

[TurboDave]

Here's a poser for ya'll.

As many of you know, I have recently upgraded from a Translator +/Exetender and LS1 MAF to the Translator Pro/Extender pro running in speed density mode (mafless).

All I did under the hood was remove the maf and it's associated plumbing, install a very long solid maf pipe with a hard rubber 90° on the end and my filter attached to that (setting right in the charcoal canister's position).

Now when I jump out of the throttle after a hard pull, I no longer get the loud obvious compressor reversion noise. It's virtually silent, there's some, but very hard to hear??

Wonder why that is?

Maybe the "surge" of air is less restricted and exits faster?

oh man that sucks! i love that damn noise, ive scared so many people out of racing me with that one lil noise.......i dont care if it costs me 80 horse i cant live without my whoosh

Thats really odd, I too upgraded to the MAFT PRO and am running Mafless and installed the BB 67 at the same time and mine got ALOT LOUDER!!!!!!! Hell it even makes the noise under light excell while under vacumn if I let outta the throttle

Where was the air filter before the upgrade? When I moved my filter from under hood to behind the bumper the whoosh sounds changed a bunch.

Dave,

It sounds like you need to upgrade to a bigger turbo so you can have more inlet noise when you back off the gas. I think a T76 should do the trick for ya.

Before the change, the filter was in my homemade cold air kit location down behind the parking light driver's side. Now it's in the area where the charcoal canister used to reside.

I know what ya mean! but a 76

Are you currently running 4" plumbing from air filter to the turbo inlet?

If you upgraded from 3" or 3.5" to 4", maybe the velocity has slowed down and dramatically changed the sound. I know when I switched from 3" to 4" on my current setup, the sounds completely changed as well.
Just a thought.

Nope, it's all still 3". The only change made was the turbo inlet (MAF) pipe is much longer, and the filter is attached directly to it, via a hard rubber (truck) 90. This puts the filter as far outboard as is possible, sitting fore and aft right behind the hole in the front support behind the headlights.

Dave,

Can you put the maf back in (unplugged) the intake setup? That may be where the restriction is that causes the air to stack up in the compressor housing giving the whoosh sound.

Not really, the maf pipe I had with the maf is gone, and things really wont fit now.
