Thread: Cone filters

Geddy, Im curious as to how you held down the PCM? How hard was it to service the air filter when needed? Im also curious about the IAT location. Would that not give you a reading that was off a bit being where you have it as opposed to closer to the Throttle Body?

Im going to be playing with some ideas I have about setting up such an intake that will hopefully work a little better with holding down the PCM and making the filter a bit easier to service. Now that my car is down and I just about got the transportation issues worked out I can turn my attention back to getting the GTP back on the road along with some ideas I have wrote down and wanted to work on.

Where the IAT is at is only correct for the air entering the filter. Where GM placed it is where the PCM calculations from. Ideally an IAT sensor LIM would be more accurate, however, thats not the location the calculations are based upon either. With the stock location where it at, some extrapolating has to take place and based on a stock vehicle to be totally accurate.

The PCM was actually just free standing. Its so heavy it doesnt move. I just put piece of foam underneath it for vibration purposes. It never moved in the couple of months I had that Fenderwell intake installed.

The IAT line you see going into the flashing actually lead into the PCV piping sucking in the air from the filter. So it was getting more accurate air temps. The setup I had, had the filter almost touching the bottom of the inside of the fender behind the foglight.

Reptile has a much better setup where his filter actually sits in the gap above the tirewell just inside the part where the pipe turns into the hole from the engine bay. He cut out the brace that connects the fender to the frame of the car to achieve his setup. Its a pretty neat setup. He will have to post some pictures of it to get a better feel for it.

Either way it is more difficult than your average changing of the stock or CAI style air filter, but the benifits are so much more
