How have u guys done it and what pipes u buy to make it up etc? Cheers rob

 

Perrin inlet pipe, with the samco filter to inlet. then a small length of 90mm pipe to join the samco to the filter. In this pic its a K&N RU3130 which was previously mapped to 440/410.

Ideally get a hard pipe made as these silicone ones can be prone to sucking shut when they get old and soft, if youve got a big power build and too small a filter.... the filter in the pic is too small really so being replaced with a bigger one (hope it fits!) before final mapping.

 

IIRC you can disconnect the MAF and leave it in situ (not sure this wouldnt get ruined over time though). Alternatively you can buy a HKS hard-pipe, i got one for around £20

 

^?????? please explain avery, what ecu are you running to have gone mafless but still need the maf sensor plugged in?


.... sorry, misread that! ..... what your saying is that the maf sensor pipework, the sensor and all related shebang can be left in place just to connect filter to turbo ..... fair point!

 

nope i thinks hes saying as in my case

im using an aps cak. I was using it with a maf. When i switched to maffless i just left the sensor in the hard pipe but unpluged.

 

I meant you can (IIRC) disconnect the maf plug but leave the maf housing in situ with filter/air box on the end. MAF becomes defunct but pipework looks more OEM

 

I got a Simtec and as u said got the maff there just unplugged but looks crap just tidying bay up at mo . So any set up s like legacy gtb s set up preferably with a rcm large cone filter ?

 

As above i watched jgm map a v1 wrx recently and what he done was just unplug the maf and leave everything in place. Ie standard airbox, Piping the lot. But most remove it and fit induction kits or whatever really

 

Cheapest way is to find 2nd hand versions of either this for v1-3...

or this for v4-6...

Nicest tidy up mod to do when going mafless is to replace the idle control valve feed from just after the maf, with a small crank case breather filter.... as seen in my pic.

 

just noticed where your alternator lol.

 

You can go route with custom inlet pipe from intecooler pipework and some silicone couplers,this should be OK

Car was very much still work in progress when this pic was taken!

Alternators not the only thing missing!

 

was that k&n big enough for 410

 

Yeah, it wasnt a restriction at all!

Danger is, as it gets older, the silicone gets softer and is then more likely to suck shut.

When its mapped next it will have an RU1785, which is slightly bigger so should be good for 480.

 

can u send me a link for the filter u getting please

Cheers Micky after the rcm one now but need a trumpet to fit
