Rex, it was great talking to you about Stu Van Dyne's theory! Ironically, as soon as I hung up , I received a conference call from Pops29, and his engine builder, Kenny Boyd, owner of Valley Balancing.
Kenny had just finished cleaning, magging, and psi checking the block-it came out fine! Kenny had the same assessment- go to coated bearings and heavier oil! He too, thought our clearances were fine-said we could even close them up some with the coated bearings.
Both of the above conversations caused me to pull over on the side of the road. I want to add H2O injection on the FlatCad, and had talked to a couple of dealers for Snow Performance Parts. Unfortunatly, they didn't want to take the time to listen to what I needed, but instead kept wanting to sell me a computer controller to run the injection system. That would be great, but it's not allowed in the Vintage class.
So, this morning I decided to make the 300 mile round trip drive to visit Snow Performance Parts. After explaining what I needed, they said no problem! One guy headed out to grab the setup I need, while the other guy explained it to me. It's very simple- a psi switch is activated at a preset psi (ours will be 7psi), and kicks the electric pump on, that supplies the injector. As boost falls below that preset number, the pump kicks off. I'll need to tap the intake for the boost hose fitting, and the injector hat for the H2O injector, and do a little plumbing and wiring.
I'm real curious to see how this effects our intake temps, and HP, on the dyno!
