Hi all

I have 2 x Q45 AFMs for sale both in excellent condition both come with plugs. They are the yellow labelled Q45 not pink.

Will sell as a pair for £160 + postage or individually for £85 each + postage.

Will post pic tomorrow

BTW
Bought them fo rmy GTR but now going D-Jetro route so no longer needed.

These are 90mm diameter not the 80mm Z32 size.

Whats the difference between these and a z32,as I was always told to get a z32 if im going for more power.
From what I remember you need a Z32 if you going to about 500 horsepower. Q45 is ok up to that point. ;)

Q45

I was told they are good for over 400bhp each.

I was also told the Z32 has better resolution than the Q45 but the Q45 is measuring more air due to its size so would have thought htey shoudl be similar.

That said the Q45s are generally in better condition than the Z32's I have had, I don't know why but they are.

There is a setting on the PFC to support this AFM the VH45 or VH41 or somehtign like that. Seems to be a normal mod for the Aussie boys on the single turbo skylines and lets you run a bigger filter.

I will post on the Aussie forum see if I can get any more info

If you could that would be great.

Its only because my car is going in soon to have an Apexi AFC fitted, and it will probably put the std afm right on its limit, plus if I want to upgrade in the future ill have to search all over again.

Q45 Afm

Hi Mart1n

I have done some digging around and found the following table

Rule of thumb for Air Flow meters RWKW & Engine BHP

------ ---- OD ---- RWKW ---- RWKW ---- BHP ------ BHP
No of AFM's ---- ------- 1 -------- 2 -------- 1 -------- 2
RB26 ------ 65 ------ 149 ------ 299 ------ 271 ------ 474
RB20/25 --- 80 ------ 226 ------ 453 ------ 376 ------ 683
Z32 ------- 80 ------ 255 ------ 511 ------ 415 ------ 763
Q45 ------- 90 ------ 302 ------ 605 ------ 479 ------ 890


This is from http://paulr33.sauvic.com.au/

So think that answers the question Q45 will support more BHP than the Z32 :D

Q45

Hi daveb-gtst

No, not at the pod on Sunday.

I have sent you a PM, if you want the AFM let me know and if you need it urgently i can send it overnight to you.

hwoarang

If dave wants one then yes both have gone. I can get another from the same guy I got mine from. I have emailed him and he has one left. But he always says that :)

If you want it I can get it for you but will take 5 - 10 days. Same price
Or if Carvolutionis happy to wait I cna sned you one and get the other for him

All of them have plugs.
