I am posting some 3rd party dyno tests that were performed on the BPI Flow Stack / Velocity Stack. These tests were performed at SG-Motorsports out of Ontario Canada. Vehicle was a 2006 350Z Roadster with VQ35 Rev-Up. Vehicle was equipped with a Y-pipe back exhaust and custom cold air intake. Testing was performed on a Dynapack Evolution 3000 model with fans on the filter and radiator and the front fascia removed. There are two charts comparing 3 of multiple data sets. Data set ID's are: 'filterbaseline', 'spark_final', and 'bpiflowstack'. Details for each data set are below:
filterbaseline - performed on 1/23/08 with custom intake and 3" K&N filter.
spark_final - performed on 1/29/08 at 3:39 with custom intake and 3" K&N filter
bpiflowstack - performed on 1/29/08 at 3:56 with custom intake, BPI Flow Stack (part no. VS300600) and K&N RF-1048 filter (6" flanged filter)

Notes - shop owner is more confident with the 1/23 baseline run, because the engine was allowed to cool for a minimum of 10 minutes before the pull. He claims the 1/29 spark_final run was not allowed to cool, but was the highest pull that day.

 

I guess

 

Whats the confusion?

 

I doubt anyone knows what this part is and you have provided no links or pictures.

 

Holy crap. All you guys are such advocates of searching the forums, but you can't use google? Looks like a cheaper version of a JWT Popcharger using a plastic venturi.

OMG... that is waht this is about? a crappy intake kit?

i thought it was atleast some other miracle spacer product like the throttle body spacer or something.

LAME

 

I could give less a **** to search for someone else's thread. not my job.

 

The Flow Stack is not a "kit". It is a velocity stack, which can be added to any 3" induction system. The benefits of which are boundary layer seperation is greatly reduced at the entrance to the induction system, improving the overall volumetric effeciency. In a nutshell it reduces turbulent entrance effects of standard filters. And as mentioned above the same concept as the pop charger, but in "piece-part" form which can be cost effective and flexible with intake system design. This is a universal product that can be used to replace the existing conical filter any your aftermarket
intake system for improved performance and what so many VQ owners seem to be happy about, sound.

 

I was trying to remain as "neutral" as possible. My apologies.
