It has Begun!

Probably custom fab my own. It's plastic = easy fab.

um, the maf is calibrated to the diameter of the unit. the unit measures the density / velocity of air passing between the filement. if you increase the diameter of the unit (by inserting the filement into a 3.5" pvc housing), how will the ecu know that more volume of air is flowing even though the velocity of the air did not change? you might want to check into this. cheers. jason

I'll tackle that problem once I get that far.. let me rebuild the engine first.

cool. keep me updated. i would be interested to find a way to get a 3.5hfm for the m50nv. cheers, jason

Jason, what about an S38 MAF? Doesn't it use the Hot-Wire metering like the non-VANOS motor? I can't remember if the S38 uses 3.5 or 4".

good call. not sure what the diameter is though. its definately worth looking into.

i REALLY like how the m50nv revs, i like the larger valve stems, i like the simplicity of the nv. i dont like the pesky nv idle stab, the puney hfm, or lack of power (compared to my other car.)

still debating.....what to do with "slow boat" (name given to my winter e30m50nv by my wife.)

cheers, jason
