This is my own idea for an airfilter mod, I refused to spend $200+ for someones kit that probably would not work as good. I removed the airfilter box and the mounting bracket for it. I removed the plastic L angle piece from the MAF and attached a clamp so I could change its position. I found K&N airfilter RU-1785 to be a perfect fit for the leftover space (twice as big as the stock filter). I removed the MAF screens and cut out the fins. I also cut the fin out of the plastic airbox that ataches to the MAF. I had to relocate the charcoal canister several inches back and make a small shelf for it to sit on. The shelf puts the can level with the top of the engine compartment, stock boltholes keep it in place. The metal strap on the can holds it tight. The bottleneck in the setup is the throttle body. Nothing is too cramped or loose and it works great, I noticed a big difference. cost me $65 bux total.

 

...any chance of a photo of this setup?

Thanks

This is the best pic I have so far

 

Well done on the project 83ho86tpi. Did you make a new shelf for the charcoal canister or modify the existing one? Do you have any cold air being fed into that area via ducting etc?

Any chance you can take some more pictures of your set-up?

 

I made the canister shelf from a sheet of scrap metal. There is a opening in the engine compartment big enough to stick your hand through but too small to fit the can. I used this space to lay sheet metal on and bent the tray sides around it. I bent the part you can see in the engine compartment so it would stand up, underneath it is a support piece. The strap just keeps the can from moving when I go around corners. The best plan I have for cold air induction is to relocate the airfilter underneath where it is now, I would have to cut a hole in the body for a tube to connect it to the MAF. I would make a box for the airfilter and feed it air from some type of ducting below. I plan on trying this and taking more pictures when I take it off and get more time. I am now kind of busy rebuilding the front end. Then I have to replace the intake manifold gasket I blew out a month ago, I guess I will port all the tpi pieces when I get that off. This project never seems to end!

 

This pic is a little better. You just have to remove everything and move the charcoal canister into the corner. I set it up on a piece of metal but you could use wood or whatever, as long as its secure. I put a strap over the can to keep it in place. The best setup was to use all the stock parts and slip the K&N on. Watch out it isnt to close to thr A/C high side line, that can get hot.

 

If the filter isn't boxed in it's pulling in hot engine air no matter where you put it, unless it's actually in the path of cold air from the outside which, is way it needs to be in a box.

 

Looks good as yours is almost the same as mine right down to the air filter. However I relocated the charcoal canister next to the battery.

Wish I had a picture but here is what I did. I used the Summit LT1 elbow in place of the factory piece between the throttle body and the MAF. I also had to move the MAF and made a bracket to do so. I also had to make an adaptor from the 3.5 inch elbow to the 3" MAF.

Now on the other side I used a piece of 3.5 inch tubing bent at a 45 degree angle to go between the MAF and the air filter. I also had to make another adapter from the 3" MAF to the 3.5" tubing. The RU-1785 K&N air filter is already set up for the 3.5" tubing.

I have made up a sheet metal barrier so that the majority of the hot air from the engine compartment cannot get to the air filter. It draws most of the cool air from the big opening in the fender well. I have two other tricks that I have to keep secret in order have that edge. Hehehe.

You are right about the MAF being the restriction and that is the point. It will flow at over 700 CFM dry air with the mods and that is good for a heck of a lot of horsepower. So now we know that the intake tract is not the restriction to producing good horsepower. Allen

 

The aftermarket ones do seem like a lot of $ for what you get.
