hello i am installing an ati procharger p6000b on my 97 z28 i have everything just about done and have a couple questions one is where do you guys have your maf at the instructions that came with the unit say to put it on the intake before the supercharger?? i have read somewhere that people are putting them after the supercharger ??? also why do i have to mive all my pcv and the breather on the passenger side valve cover to within an 1 inch of the airfilter??? along with the breathers for the opti???? also where is the grey wire that i have to tap into for the fuel pump the suplied wire they cave me is only about 1 or 2 feet long??? last they say to hook up the yellow wire for the fuel punmp relay to the ground wire for the stock fuel pump i was woundering why i just cant ground out this wire insteat of trying to fined the gound for the relay another quick question about what plugs to run? i am running ngk t5 they are the same as the autolite 103 so i was woundering if this is ok?

Thanks for the help

You don't have to run the pcv hose to within 1" of the filter. I think that is just for emissions. Mine is running to the pass. side fender.

I moved my MAF to after the head unit but you have to buy some extra hose. I fabbed all my blower tubing so I just bought some 3.5" to 4" reducers(silicon) for the maf.


Can't help with the pump. I can't remember and I switched to an in-tank anyway.

 

thanks so what you are saying is it realy dont matter wher the maf is located?

 

You can do it either way. As far as efficiency goes, I don't know what is better. Before I even installed mine, I chose to put it after the head unit. I felt like the stock setup which was one size at the blower inlet, then necked down to fit the maf, was not as good as my current setup. Now it has a full 4" inlet with a 4" filter inlet. It blows through the maf with no decrease in tubing diameter. It actually increases diameter at the maf ends.

Some people say it helps there idle when the maf is after the unit.

 

With respect to the MAF, I would place it on the incoming side of the blower. When I switched mine I had some drivability issues. Same reason why many OEM turbo/supercharer equipped cars have the MAF before the blower/turbo. I have seen others run the MAF on the pressure side without issues, but procharger and other companies seem to recommend against this practice.

 

thanks again guys
