car is awsome
I didn't realize there was that much involved with the ITB setup! That is much more intricate than I had imagined...and WAY better! LOL
Warren, what's the passage at the rear of the ITB plate for? My guess is a vacuum port but doesn't it show a lower pressure than what a "stagnant" manifold source would due to the higher velocity at that point in the system? Or is it quite unstable due to the dynamic nature of each port? Do you have an external reservoir that stabilizes the signal giving more of what we are used to seeing in a manifold or is it still a lower average? I guess there is no real alternative to record the pressure post throttle plate but I'm curious about your experience with it.
The main plate is milled out hollow from the rear mounting bolt holes back to the welded-on tube. The tube is slotted open where it joins the plate, the volume of the hollow plate and tube is the total vacuum chamber.
The small holes drilled from the throttle bores to the vac chamber provide the chamber with cyl. to cyl. average manifold pressure. (either negative or positive).
No external vac. reservoir was necessary, the tube and chamber damped the cyl.-cyl. 'crosstalk' very well as it turned out.
While the closed throttle vac. signal is not as steady as a single throttle system, it is surprisingly steady, but because there are four throttles to bypass air at idle, the vac. signal is weak. (2-3" @ 800 rpm with big cam).
Fortunately The Electromotive software has a TPS/MAP blend routine that allows the tuner to assign differing amounts of authority to the MAP or TPS signal voltages during idle and throttle opening transitions.
With the new head, cam, and bigger intake, the throttle bores are now too small. I plan to bore them bigger and install larger trumpets, just didnt have time to do it yet. I'm running now as a restrictor plate engine.

WOW! I did not realize the throttle body was one piece! It is very similar to what was in my head to build for my 2.4L. Amazing work!
YUP!!!
I can take it a little farther and give you a real bad idea!!!
In 88 i was working for Diamond engines and the guy who work there made a alky motor with rotorary barrel valves the problem was the tech at the time couldn't support the Rpms that the motor wanted to rev too he spilt 3 soild alu. blocks in two.
and from what I've heard they're like on-off switches.
Wow, that is neat.Fortunately The Electromotive software has a TPS/MAP blend routine that allows the tuner to assign differing amounts of authority to the MAP or TPS signal voltages during idle and throttle opening transitions.
Dont push the red button.You hear me?
They make a bolt on rotary valve set-up for the Ford 5.0. I saw it about 10 years ago. Interesting to say the least.
That header is pure sex,
You missed the pics of your trans pan,
I think he means you can see the belt deflecting at idle, so at 7000K, you can imagine there's a bit more, so that will affect your cam timing etc.
That's what I was going to ask.
Yeah, I saw that, more power, more mpg and oil life went thru the roof.

Is it steel? If so, I thought you made an aluminium one?

Ok Warren, you got me on that one. How did you make the "ribs" in the bottom of your pan? I know "how" to, but that would mean I need access to a press and a torch to aneal the aluminum beforehand. (I worked for a short time at a shipyard running a few presses, brakes, and shears.... but 6 months isn't enough time to be an expert)
