Just remember that the plenum was a quick test, and certainly not the best design.  As you'll see, there are two inlet tubes, because they have a tight turn to make under the radiator duct.  Eventually, this will be reworked into a single, larger inlet without the tight turn.  That should eliminate some of the intake pulse abuse of my plenum, which of course will have to be replaced too.  

 

In one picture, you can see where the flat side of the plenum is sucked in, and allowed to pop back out with every intake cycle.  The crack you see formed in only a few minutes of ground running, and all you could see was a blur of the plenum expanding and contracting.  The new crack is just like this, only on the bottom side.    

 

I'm still very happy with the intake, though I will modify fuel rail, and make a sleeve to adapt a pair of MSD injectors to fit in the primary locations.  Matching injectors are a good thing.  My only other concern about the intake is that it may become restrictive at higher power settings when I get the C drive installed.  Time will tell. 

  

BTW does your RV8 buddy fly for Fedex?  If so, tell him I said “hello!” 

 

Yep, that's the one.  He said he's going to prime my wings so he doesn't have to be blinded by the glare from bare aluminum :-)
