Ignore, I scaled the diameter only, so you can tell me to take my GCSE's

Just used: πr²

2.5 (63.5mm)" = 4.90
2.75 (69.85mm) = 5.94

A scale off 1.21 or *121% try that

N75 in that log Nick.  MBC was jerking all the time!

Need to run it Parallel with the N75, its boosting too hard just with the N75, you need to clip it where I left it as its setup for that amount of load, not the load the N75 was giving due to your boost gauge.

[Chris.]

Will get it plumbed in like that tomorrow and do some more logging!

I know I shouldn't go by what my gauge says but it's only saying 16psi spike, still pulls like a train though. Can't see that stressing it too much lol

Think we need area.  It would be ok if the lengths were the same, but VR6 is longer.

I have:

Stock maf:

62mm width (ID)
96mm length

VR6 MAF:
76mm width (ID)
130mm length

That any help?

[Wazzzer]

also I might plumb in my proper calibrated vac/pressure gauge I have at work and see what the proper boost figures are, just hope it has the range I need as I only really use it for vacuum, never tried it with pressure

hay nick desprately been trying to get hold of you all week can you give me a ring mate i emailed you to my numbers in the email cheers mate

VR6 MAF:
76mm width (ID)
103mm length

That any help?

In that case:

Just used: πr²

62mm = 3019
70mm = 3848

76mm = 4536 (you sure, this seems to huge as ID)

A scale of around 1.28 or *128% using 62mm and 70mm which is what nick was saying

[Chris.]

its actually 70mm,  I was measuring the square filter end which goes into airbox.  (that side is slightly bigger.

so the VR6 MAF is 28% larger.

This is from a page I was reading when looking in to maf v injector flow rate.

"Stock 2.5" MAF = about 2.4" at the sensor, radius = 1.2"
New 3" MAF = about 2.8" at the sensor, radius = 1.4"

So, the area increase is:
[1.4*1.4] / [1.2*1.2]
1.96 / 1.44 = 1.36
