my latest project
All right, The new project is fully underway and I can't wait to complete it so I can test the results!
about a year ago I was planning to start a major project on my truck I hit a deer with my truck. For years I had wanted to do some major engine modifications to increase power.
I had a plan to port the cylinder head and I was going to build a flowbench so I could do it up right.
Then in the blink of an eye....
Blammo a deer ran out in front of my truck and totaled it.
My project was sidelined.... for a new project....
truck repairs
Now my truck has the looks, so it's time to get back to the performance department.
I've built the flowbench
flowbench
and practiced the porting on a junk head.
Now I am working on the real deal
Using the "knowlege I gained from my experimentation on the junk head I was working on the intake ports and had gained about 18% flow.
But when it came time to get the flow matched between the ports, I ran into some trouble.
It seems that the "swirl" port design on the 22RE head is very tempermental and once you get beyond the stock flow even small chages in the port make large and unpredictable chages in flow.
At this point I decided that a different approach was necessary. Redesign the ports.
So I ground out the inside turn in the port creating a nice radius and then used a special epoxy putty to fill in the outside turn and reshape the bowl area.
Here are some pictures:
I put this on the flowbench and was shocked at how much better it flowed About 50% increase over stock form.
Ive got about 25% increase in the exhaust and when I'm done with the head later this week I start on the intake manifold
I'll keep you posted.......
P.S. I'm still waiting to find out the diameter of the oil pickup tube

I was working on matching the ports, Slowy changing port #2 to catch it up to port#1 at 90% flow on my scale (about 209cfm)
Then all of a sudden,
We have a new winner! 91.2%
yesterday I decided to test the flow through the head with the lower intake installed. 13% loss (was 3% before port redesign)
What's a guy supposed to do?
Well this is what I did......
I got out the cutting tools
And.....
Started modifying the manifold

I got most of the welding done and started grinding out the ends of the runners to match the wider sections.
Here are some pictures
The first one shows two almost finished runners and two before
The next two are before and after down the tube shots

This weekend I was going to build the plenum, but once I got started I realized that it would be best to weld up the plenum adapters (cut off pieces of the old plenum) and port them out first.
Here are some pictures
first one is the old and "new" throttle body
Can you say...WOMBO?
These next two are of the welded up plenum adapters
and this last one is of the ported and bellmouthed adapter
I'll work on it more this week. Hopefully getting the plenum done.

I've been working towards completing the plenum. After I got the plenum adapters basic shape down the I welded the lower plate of the plenum on.
Then I shaped the bellmouths up off the plate by forming them with weld.
This is looking straight into the bellmouth
Tomorrow I'm going to finish smoothing it out then I'm going to switch back to matching the port flow with the manifold in place.

Yea I know, I wish I had a lot more experience welding so that I could make it look pretty too. But so far it is all pretty solid. The last shot inside the bellmouth you are looking at the Inside of the welded material and so far I have not encountered any porosity So it should be strong. I'm going to grind the outside as well to make it look better.
