454 Oval Port Dyno/Drag Test

Your so correct on the humidity killing horsepower. We do get mind shaft conditions in March and around November LOL. Hard to burn all that moisture, great build and information.

When I lived in Colorado it was always about the baro, when I moved to Tx its always about the humidity, the killer of HP.

80 degrees
78 Humidity
120 GOW
29.5 Baro
2400-2800 DA
475 Elevation

Thanks, You get mineshaft air in Houston, we are at 475 feet elevation, I have yet to see mineshaft air in Tx, never seen a 30.0+ baro yet to this point where I'm at. I'm going to Extreme Sunday, so we're going to know what I got here. Of course the day I dyno tested this engine the humidity was 30%, I wanted wet conditions for my dyno testing because that's always what I get at the track. Any predictions.......anyone.

BTW the quickest and fastest I've ever run was @ Houston! 600 DA 30.0 baro

Its done @ 6400 RPM, but it will hang on to 7000 RPM.

Thanks so much for the simulation! And I knew this was going to be the results when I couldn't get into the 6.20s, I saw the 6.31 on the board from the driver seat on the first pass and I knew I was in trouble, then another 6.31 on the second pass, we then dry iced the intake as it was heat soaked, but ice got mixed in with the dry ice, and of course the water came, we tried to pick out the ice and run it, after the burnout they shut us down, it was heart breaking, we went back to the pits and cleaned up the mess, by this time there was no more dry ice, as we got the intake cleaned up the heat came right back into the intake, a horrible mistake was made that day and it cost me the 9s, we made a final pass, of course the power adder freaks were out and in the lane next to me, I went into the beam first and waited for the power adder, he finally lit both bulbs, I rolled in, but to slow for the starter, he red lit me, I ran through no time due to the red light, But we had the draggy in the car and it read 6.31.........................

By this time I've had enough, 200 mile drive home, to late to make the road house, screwed again in the TX conditions, but the best part of this whole thing is your simulation, thanks so much!
Thanks to Larry Meaux for the simulations!

Three 6.31's....I know you want more but I'd be happy to bracket race that!! (of course, then my bad lights are more obvious when I have a bad package) LOL

What kind of exhaust. It?s a nice well working car I see.
