Can't wait to see how it turns out, Lee.

Excelent work Lee.
Are the throttle blades off the shelf or custom made?

Q's:
Is there a flow rating for stock? How 'bout for 63mm? And with 63mm, where's the bottleneck inflow THEN, with stock non-ported plenum / IH's? AND... how well do they hold vac @ idle? When I re-assembled my TB after top end housecleaning, I could see no light around the blades, BUT, when I had the 2nd TB butterflies blocked with the restrictor gasket, I saw a BIG difference in steadiness of idle RPM, attributable ONLY to air leaking by sec butterflies that LOOKED sealed... |

Lee, you mentioned using a substitute for the DAG compound. What would that be?

I'm intrigued! I'm quite familiar with molybdenum disulphide as well as tungsten disulphide dry lubricants (we coat bullets with the stuff to reduce fouling). Both will adhere well, tho some peening (or "sand blasting" process) may be necessary to get it applied.
However, unless there is some kind of bonding agent, pure moly or tungsten will be removed in the presence of oil...which is likely to be present (to clean moly OR tungsten from my rifle barrels a combination of penetrating oil among other chemicals makes short work of either). So! I know you do you homework, and a dry lube like Moly makes a lot of sense, but I'm just curious what exactly is this moly stuff is mixed with that is being applied? Shrade's Parkerizing comes to mind as an agent that can be applied, that has some inherent dry lube abilities, and is impervious to (gun) oils. Then again, I wonder if Jerry's Gaskets has any of the original DAG stuff? |
