EFI intake tube - minimum length

[nvrstuk]

I need to move my intake tube to my Victor upper plenum on my stroker.

I remember reading a long time ago that the readings on the mass air flow sensor can sometimes be affected by the pulses through the intake manifold?

If so, what is the minimum length as I will reroute the intmake air later for cold air intake through the hood but for now I will have a couple of trips on it this fall and I'm not worried about peak horsepower with cold air for the intake...

I've got a text in to Garry as he's my tuner on this thing...

Ive seen 4" & 6" posted on other forums but have no idea. I'm currently re-arranging mine and would like to know also.

Short "works", but is not as ideal as having your MAF having double the intake pipe dia on either side of it unobstructed...this also means curves...but that's theory...look at how many MAF sensors are located at the base of the cone filter!

Air wash usually keeps us from having the MAF and filter connected directly to the TB...

double the intake pipe sound reasonable, thanks.
