Yeah, you are correct. This allows you to run a larger air filter element with a 4" outlet connected to a 4" diameter intake tube with a 4"-to-3.5" transitional coupler connecting to the 84mm inlet on the compressor.

By doing this, and in conjunction, switching from the stock MAF setup to SD, you would be getting rid of several major intake airflow restrictions. Add to this a ported TB and IM, and you would potentially have a pretty decent flowing air induction setup.

The FP designed 84mm compressor housing features surge ports and was originally designed to help eliminate compressor surge on the FP Red turbo. It comes standard on the FP Black, but can be machined to fit other compressor wheels such as the HTA Green, and the BBK-Full. I think that someone is even running one of these covers on a stock IX turbo.

 

This is something EVERY BBK owner should add to their Setup for the 75.00 price they are offering..

 

I have one on my black and love it. Can't beat it for 75$. That is a ridiculously low price. I say get them while you can. I'm shocked its that cheap.

 

Im actually really hoping that Chad bites the bullet, and adds this surge port as a standard for the BBK-B!!! I know he states "his turbos dont surge", but 1. its a peice of mind, that it wont surge, and 2. the cherry on top is the "whistle"... A small part of me wants that whistle... And might even be willing to pay that $75 extra for it!
Or I could just get an FP turbo...
Ideally I would love to have a B w/ the surge port!!!

 

This is a bit like putting a SBC in a 5.0. It may work but a lot of people are going to just have a brand loyalty hang up.

 

Just get the HTA Green ...Seeing as you are in socal, let me know if you want to meet up in/around Del Mar and see what an HTA Green can do...

 

thanks, I'd buy one but I am still on the ecu & not on speed density.

 

Now we'll just have to wait and see whether with the release of the BBK-B, FP plans to cut the 84mm flow advancement cover to fit the B's larger comp wheel. I tnink that the B's higher flowing comp wheel could definitely benefit from one of these puppies.

 

Don't get me wrong. The FP Flow Advancement compressor housing does not in anyway require a switch from MAF to SD to be used on your turbo. it works perfectly well without SD. The SD thing is just a personal preference on my part.

 

Are you perhaps gonna be trying the FP Flow Advancement Cover on your nasty, HTA Green, cij? At $75.00.....Such a deal!

 

How hard is this thing to install on a BBK? Does it require the turbo to be opened up?

 

It is not hard to swap covers. I bought one of the 84mm covers when they first came out from a friend at FP. It made a big difference at 30psi for the FP Red. I know its not the same turbo but anyway. I love the sound it makes and how it holds boost now instead of bouncing of it. I also paid $200 for it... So for $75 that thing is a steal!

Isnt it a 80mm id and 84mm ed on the cover inlet? I could have sworn they called it a 80mm at first lol.

 

Well, first off here are a few points..

the only people preaching of surge are running the turbos beyond the DESIGNED and tested boost ranges, which they are not intended for. We have always stated the BBK is designed to run in the 22-29 psi range.. not 34etc....

We will not warranty a turbo with another companies cover on it so right there that is a no-no.

We build things as we see a need, and in the past 2 years we simply haven't had that. These covers were offered to us by FP in bulk... and our response was simple, no thank you.

So, If you have an out of warranty BBK or such, and you want to run one by all means do so. Typically if you take an antisurge cover to a non (in the same size) you will not make the same power.. simple aerodynamics...

food for thought.

Ahh Man.. Such a party pooper Chad.. No warranty..

 

I will never buy another CBRD product. voiding the warranty for changing cover out. That is sooooo cheezy I hate companies with poor business ethics..
