So the next collection of parts is starting to arrive.

New fuel pump.


Stand alone IAT


Larger maf housing with 83mm ID

I am also going to have to change the BOV to a type that is attached by a silicone hose, as there is simply not enough room to accommodate the existing bolt on BOV.

Does the maf body incorporate an air straightener?
If not they're easy enough to add if required... eg alloy honeycomb etc

No there isn't one fitted, do they make much of a difference?

It's about getting consistent results from the sensor, they like a straight shot of non-turbulent air afaik...
I guess if you're not getting the results you seek, look at issues related to big bore Cai's.

So the new BOV turned up today, this is the one recommended by the SC supplier, its by Forge Motorsport and has 40mm inlet and outlet!!!!

Sooo what needs to be done now before driving time?

Ooooh forge motorsport... niiiiiice

If you look at the pic above, what will be done is to put the new maf housing and Bov in a straight line between the sc and before the 45 degree bend, then fuel pump and stand alone IAT then back to the rolling road for the final numbers.

sooo close!

Finally got my wheels refurbed with new 235/40/18 tyres. Very happy how they turned out.

The wheels look mint man!

Looking good!

So a semi successful day yesterday trying to sort out the final few things before the next mapping session.

So we installed the new IAT sensor into the charge cooler at the point we thought it would see most air flow.


Then we set about changing the inlet tract from this.


To this.


The main purpose here was to put the maf in a larger dia tube to help with better scaling and also to put in an area of reduced turbulence. We did try starting the car with the new set up but it was to much of a change for the map to work with. So now I will drive to the mapping session with the old set up then install the new one and get her mapped.

Oh and some complete arse ordered the wrong type of fuel pump for the Legacy so I need to get that swapped and then install the correct version.

The stand alone IAT sensor worked a treat on the way home with temperature ranging between 27 and 36c depending on traffic and driving style, so happier now I know the ECU is using the correct temp to calc the mass air flow.

I am about to go to post intake cooler IAT sensor too

Please keep me updated about driving feel after this move, to say very interested would be an understatement.

Awesome prgress youve made mate!
The new intake path looks like it'll really get the job done
