What to do about my air intake?
Hi all,
I've recently done a TPI engine upgrade from a Camaro into my 82 Trans Am using MAF, and I'm not sure on the best way to route my air intake ducting.
The battery on my car is on the right hand side which for this is a pain because that would be the easiest place to put the pod air filter. The "best" solution I've come up with is shown in the attached pictures as it allows me to put the pod air filter on the left side of the car where it can get cold air. But this is not without problems because of the sharp downward angle of the rubber ducting with potentially is upsetting air flow. The MAF is right behind the radiator so I imagine that will pick up some heat, not to mention the upper radiator hose (although I do have an air gap between the MAF and radiator hose). Would the MAF picking up on heat be a problem how I've installed it?
I could route the ducting to the right as shown in one of the photos and attach the pod filter immediately onto the end of the MAF, but it would still be right behind the radiator, thereby picking up heat from there.
I could also relocate the battery, but that involves more work than I want to take on. I could also convert to SD and forget the MAF altogether but that's also more work than I want to take on right now.
So, suggestions etc welcome.

My CAI goes to the passenger side and the MAF sits infront of the rad yes but it's not directly up against it. Only solution I see is putting the battery in the back of the car and go from there. I'm just letting you know it's ok to run the CAI on that side of the car, regardless of the location of the MAF sensor.

I don't fancy cutting holes in my car to solve the problem, and I'm minus the Camaro plastic piece that sits over top of the radiator anyhow.

My MAF is attached to the upper radiator shroud and I have a K&N Cone filter at the end of the stock intake tubing.

Thanks for the pic. I see you battery is on the driver's side. I'm now wondering if I actually should relocate my battery. Where/how do you battery cable route in the engine bay?

I use a K&N cone type filter. Next year my CAI will be totally custom. The pan where my charcoal canister is sitting will get cut up enough for a 3 1/2" 90* tube to go down and thats where my filter will be mounted. The passenger fog light hole will than turn into a ram air duct that goes directly to the filter. Once finished, should work nicely!

Negative runs from the battery to the drivers side of the motor.
Moving the battery to the pass side should be no problem, just have to run a smaller wire or two to the drivers side for any connections that can't easily be moved to the pass side.
My 86 Trans Am had the battery on the pass side stock,

and I eventually moved it to the trunk when I converted to SD TPI with my SLP Dual CAI since the two airboxes used both battery trays.

Does it go along the engine cross member and then to the starter, or along the back of the radiator or something? I can't quite imagine what you're describing sorry. Your car had the battery on the left side stock didn't it? For giggles I'd like to replicate the stock appearance.

We're supposed to change out my y-pipe tonight and if we do, I'll get some pictures of the cable routing so you can see exactly what you need to do to move your battery to the drivers side.

My original positive cable ran across the bottom of the radiator support and was attached to the lower fan bracket. It then went along the passenger side frame rail to the starter. The negative cable was attached to a bolt near the oil pan that held my power steering bracket on.

Thanks very much for that description. That helps me a lot. I think I will relocate my battery after all!
