Anyone?
I am by NO means a mechanical engineer ..BUT I am a "back yard" engineer. the difference? Engineers believe in theory and what they see on paper...Backyard engineers believe what they experience and learn by the application of PLAIN COMMON SENSE and mistakes. SO....here's my take on it
Why the triangles?
To manipulate the flow of air. There's no rhyme or reason to it...Jason stuck the sucker on a flow bench (assembled with heads and intake) and came up with the shapes he did because they gave him the results he was after. With further experimentation, many different combinations of shapes (even circles or flower shapes) probably would have given the same results. Why bother though...
Why no egr hole?
Not every one runs an EGR. It's easier for the end user to drill a whole than fill a whole.
Why is it so thin?
It doesn't need to be thicker. Plus, if it was thicker, you would need new bolts among other things.
Why are there no deflectors?
They aren't needed. The flow of air is controlled by shape.
How much air flow is lost due to the restriction?
Ok...take out a tape measure. Measure the area of your stock plenum. Now, measure the holes in the power plate. Which # is higher? Fact is, the stock intake plenum is Larger than it needs to be. Look at the intake setup on a GM TPI 350...the actual volume is small. Does it make any sense to put a larger area after the throttle body? Smaller the better. The throttle body only flows so much...AND let's not forget, not all 6 cylinders are taking air at the same time.
I run a Big Block blower engine...there is a similar plate (for lack of a better comparison word) that was once used with blowers. It's purpose? To more evenly disribute air....Guess what? It was outlawed because it offered an unfair advantage to the users.
In a forced induction engine things work different than in a normally aspirated one. Don't make the mistake in applying the same logic...it doesn't work. When pressurized, an intake charge is going to go, well...some where...everywhere...it's not so much a matter of flow as it is a matter of direction. Kinda like the "gasket match" thing on the intake...it's been proven time and time again that this is a WASTE OF TIME in a forced induction engine, but hell....I still do it. Old habits are hard to break.
Bottom line is, try it. It's $59.00. I've wasted more money on cleaning supplies or beer. The plate worked for me. it might work for you...it might not.
