Finally you ***** guys have started to think about the plenum capacity issue.
Have you ever logged Your boost separately from front and rear cylinders?
Pretty poor design from what my research is showing. The flow is reaching 0 by the time it hits the back wall on the plenum. The flow then also has to go around a piece of angle iron welded into the bottom.
I would like to add small flutes in the bottom and cut the top off and angle toward the front. This way the flow would come in and angle down to the flute. Thus giving a nice smooth flow.
Now to measure the flow to both cylinders I suppose I could use the inspection ports to mount 2 different gauges to measure the boost of the front and rear.
I am up to hear as what you think about this matter Karzza.
karzza you are way further in this then we are.
I accept any and all wisdom on the matter of the plenum.
I understand that the bigger plenum will allow for the more upper end of the HP range.
A smaller plenum will allow for the lower end and torque help.
Then the how to find the happy middle and correct flow is what we strive for.
This is one big learning process.
Tying to figure to Cubic Displacement to use 1/2 to 2 time the displacement.
I am going for 3/4's of the Displacement.
Learning the intake runner length for flow and cooling of the flow of air.
My head hurts already!!lol
