I decided Ted needs a little more power. I bought a used TBI kit for an L head and a used Saab low pressure turbo. I think fuel injection and a turbo will be perfect for the little L head. Waiting on my TBI kit to come in, but there is plenty to work on. This thread is what got me thinking that a low pressure turbo would be perfect for the L head. Saab "light pressure turbo" technology? - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com This morning, I went to the local salvage yard and got the perfect air filter for the project. It is off a Ford truck with a 5.4 liter. As much as I love the oil bath, I don't think it will flow enough air for the turbo. I cut the intake snorkel off the filter box. This left the grommet behind and revealed a nice barb that I will use later. While messing around with the filter box, I realized there was a barb on the outlet side of the MAF sensor. Where the stock outlet tube connected is 4.5" and the this other one is 3.5". It would also reduce the height by several inches. I wrapped the outer housing with some 1" masking tape to cut the housing off. Which now turned the filter housing into this. There are 3 holes that need to be plugged up. The little one on the left side is a drain hole. Not sure what the two big ones are. I cut a piece off the piece of housing I cut off earlier and glued it over the holes. I cut some of the stock mounting bracket away too so I can use it. After making up a new bracket that bolts to the stock mounting brackets, it is starting to look like something. So the plan is, the outlet side will go over to the turbo and the inlet side, which is pointing at the ground, will loop back up, go out the hood and over to an M38 type snorkel on the windshield.
