check out where the air filters are - cant this cause problems

Cos, the guys over there often refer to this design as a CAI, they do it on many of their other jap cars and works well, in certain states anyway with decent weather, to combat weather in other areas they use an AEM bypass valve, this soaks up any water before entering the maf. The design is actually very good, hard to confirm from the pic, but the pipework does appear to be greatly shorter and this is a bonus, the pulsed air travelling through it is stronger giving higher voiltage readings, thus more power.

The practice of moving the maf on jap turbo cars inwards is very popular in highly tuned motors for this reason alone, just a bitch to do on the Zed. Done it on a Silvia and it worked well

While we're on the subject of that car, the B.O.V's are on the two inside hardpipes, from the throttle bodies (as seen here http://z1motorsports.com/Image%20Gallery/Customer%20Cars/300ZX/Mike%20Vale/pages/IM000536.htm ) yet on a mate of mine's car they are on the outer pipes near the HICAS and fuse-box....:confused:

I'm no mechanic, so is there any difference to the function of the B.O.V's in these two positions and what's the verdict on having them anyway (cool noise aside)???

 

Cheers!!:)

The rule of thumb for BOV's on a tubo car has always been on the pipes and closest to throttle body, however in the Zeds case it seems the car and the BOV's seem to perform better on the outer ones, dunno why meself. SE do theirs on the inners as well, but i know some who have removed them and moved to the outers.

Would be good to see a good answer on this one.
