I see alot of TPI camaros that dont have the extra intake tube for the mass air or speed density sensors. whats been modded to be able to run w/o it, or has it just been moved somewhere esle in the intake?

 

The MAF is in the intake ducting, thereis nothing in there on speed density set-ups.

 

I knew the MAF sensor was in the ducting, but i see alot of tpi motors at races that dont have the ducting that the sensor sits in....alot of em just have a cone filter right on the throttle body. I was wanting to do a setup similar to that but i didnt know if i had to do any special tuning or other mods to be able to.

 

I would suspect you are seeing the differnce between a MAF system and a speed density system. There is no MAF sensor on speed density as it is not using the Mass of the Air Flow (MAF) to run it. It simply is using the Manifold's Absolute Pressure (MAP) as the primary basis of the ECM processes. I'm over simplyfing it here, but thas lack of a MAF sensor on the snout of the throttle body i's the easiest way to tell them apart.

If you a have a MAF system now, there are many changes to be conducted, particularly on the computer side and some others on the parts side I don't know your level of knowledge on the issue, so please don't feel insulted by my saying that it's not just a question of removing the MAF and firing it up again. That won't work.

Maybe an anology is that we use both automatic and standard transmissions, which although similar to each other that they connect the engine to the rear axle, and have gears, they function differently and need different forms of input to make them work. MAF and MAP are not interchangable either.

 

Ok I see what youre saying. I knew speed density cars didnt have a MAF sensor, but I was thinking there was a sensor in the same area (intake ducting) for speed density motors as there were for MAF motors. Thanks for the info.
