I am including overkill metal tie down bars that connect the box to the motor on all sides.
Really the only thing the silicone tubes between the plenum and tbs are to prevent leaks.
I never meant to say that the boots would be how the plenum would be attached to the motor.
As far as I can see it, as long as the plenum can not move away the motor via the hold downs the silicone connectors will be adequate. Am I wrong to think so?
Also,
Given the lowish psi numbers I will be making, and the fact that the thing will get used about 30 miles every other year I don’t have a lot of concerns that the thing will come apart.
I studied a few other plenums out there before I built this one and IMO this is far stronger than the standard off the shelf unit that comes with most every “stage 1” kit I have seen.
This is a pic of the NT2 plenum, and one that I used for design cues.
Same material thickness, more surface area, more welds, more corners and more boost.
If my plenum comes apart….I will blame Rick!
