Lets get a comparison of the peformance numbers....

Evo V-Flow Air Intake: 15 wheel HP/TQ.

StockBox w/K&N Filter: ___ Wheel HP/TQ.

 

I think my BMC (which is a better filter than the K&N...lasts a liketime) gives about 6-7 legit hp to the wheels.

And no blown MAF.

 

I don't think there are any documented gains of a cotton filter vs. stock. The stock paper filter is excellent with lots of surface area.

 

I made the swith from the V-flow to the stock w/K&N 1 year ago.
I notice absolutely no power loss on my 640GT. I blew 4 MAF's in less
than 3 months when I had the V-flow. I have not blown any since the switch. Anybody need a V-flow?

 

Ebaker,

Sam Shalala has gotten a consistent 5-6 hp in dyno tests w/ the BMC.

 

Wow!! that should put the EVO box to rest!!!

BMC filter and stock box is all you need.

 

K16

GIAC ECU + Evo V-FLow Intake = 490-505 HP/TQ

GIAC ECU + StockBox w/BMC Filter = ______ HP/TQ

 

I run the K&N and the stock box. it does make about 7WHP as we tested on the our Mustang Dyno. No MAF issues.

 

I have the V-Flow on my Protomotive tuned engine and have had 0 MAF issues.

 

Has anyone actually dyno'ed the two back to back on the same car? That would be the only way to tell. I'll give up 7 hp to save my MAF. Just learn to shift faster.

 

Stephen at IA has dynoed the stock airbox and V-Flow back to back.

 

And the outcome?

 

The V-flow makes a significant improvement - more so on heavily modded cars. Stephen has the numbers - ask him.

As a second point of reference, I will offer the following: Todd at Protomotive made a custom program for Gunther due to the V-flow and ported OEM headers. Gunthers car made an additional 30 all wheel HP with just these two mods. There are many that frown upon the V-flow that have never used it. I have 2 years and over 20,000 miles on mine with track days and zero issues. The car has noticably better response with the V-flow. Hmm - maybe its the V-flows portion of the Protomotive dyno proven 30 AWHP increase...
