RHS flow data from today...

Interesting. I remember Brian from IMM posting the numbers he came up with and I'm pretty sure somebody asked him about the spark plug and he stated he did have a spark plug installed. I'm sure you probably know temp, humidity, atmospheric pressure, etc... all have an effect on the numbers. As well as what bench your using. I'll be interested in seeing what you come up with on the EQ's as I have a set I'm working over for a 408 I'm putting together (would already have it done if buddies would quit bugging me to do stuff for them, LOL).

Well, I didn't see that about the plug inh is thread, but that would bum me out. Or at least confuse me. Or at least make me think we have a VERY conservative bench. The bench we used though, as been within 1-1.5% of Holton's 600...and Don Little's 110. You're going to make me have a BIG brain ache now: It was very damp outside and we were in a garage with the door up....GRRRRRRRRRRR!!!
