well im currently using 20w50 and it is knocking alittle at idle also so idk if it is that. i cant call Cam because it is Sunday. and the grind noise is 4 to 5 rpm now and only when i am in boost. still cant narrow it down at all so im blind at this point.
the noise at idle is normal--what else is happening---no clue. Does it happen on free reving?
Maybe the idler pulley?
rote i had about 12K on it but i would not count this as a blown engine because of how it happened. Dang 2 cent fuel line part.
I am thinking guys that we need fuel pump help also.Most fp are designed to produce approx 30% more than the engine requires----well i think we are past that. After break in i am going with the kenne bell.

Well Denny, you DO have the inter cooler ice box from a Mustang, maybe you were planning on adding Mustang parts a little at a time.
PS: Rick DID build a new "Rotary" not a "Boss 302"?

Also, a question/idea.
Our air intake temperature sensor is installed in the Pettit UIM (or at least mine is), which is aluminum and mounted to the engine block; I am planning on moving my temp sensor to the super charger side of the hump hose to provide a more valid temperature reading on the air charge instead of the block and intake temperature.
just have a look...
My engine bay isn't really clean yet as I am doing some mod...

Keep it up and you will wind up with a 429 RX8....
Or stay rotary....
Pratt & Whitney J58
The only problem would be getting disqualified for not remaining in contact with the ground on longer straights....
/And getting banned from the dyno.

Now here's a rotary you might get under the hood, and you'd have that "supercharger whine" to boot.
Rent your RX-8 services to NASCAR for track drying excursions. 
Allison T56
Hell, it might fit at that!

19.0 in wide and 22.5 in high; 40.8 in long....
I pity the clutch and you can forget the stock transmission.
You better get a very large resonated mid-pipe

I wonder if it can be tuned for Methanol; to run colder and be "green"? LOL

We could finally use those "gills" behind the front wheel arches for something useful; enlarge 'em about 25% and duct the exhaust through them.
Thanks for the pic, Rote. I can fab that up in my shop. BTW, is that paint or powdercoat on your sc?
whines all the way home

Dare I say it, that engine bay is "elegant". 
Zenrx8's question does raise a couple of my own, and those would be, "Can you powdercoat the Pettit without damaging the intercooler?", and "Can the weld lines be ground flush?".
