tooter's next manifold adventure...

[tooter]

Here's the prototype on the manifold...



It doubles the length of straight runner section before entering the head as well as adding a little more volume to the manifold.



This with the spacer on the engine. Installation is stupid easy. There's tons of clearance everywhere, and even the oil dipstick tube fit perfectly. You can hardly tell it's there because it's covered up by the fuel rail and the wiring loom.



With the cover on, it's literally invisible. I bet it wouldn't even be noticed on a smog test.



I drove it around today, but couldn't really tell any difference, because I'm so used to driving the tooter ET manifold and the larger Corolla throttle body. So that was giving up a lot of advantages. Still it ran good with no issues. I had disconnected the battery so that the ECU could adjust back to the different stock manifold, the different throttle body, and to the spacer as well. All three being changed at exactly the same time caused the ECU hunt around for quite a while trying to figure out the right idle. But it eventually stabilized and the engine runs just fine.

I'll see about dyno runs this week, if I can find the time.
