Thanks Pat & Barry, for the kind remarks. I'm going to have to scratch Pat off my "give him sh!t" list, for a while. Sorry Chas & Rod...
Dan- SOTP increases are going to be zip.squat with 8hp (either direction) anyway.
Dunno why they listed the runs 1, 3 then 2.
Probably the same reason why they were monitoring all 3 of my run's dyno temps/humidity next to the Pina Colada on the work bench.
They placed twin centrigugal fans blowing through my hot radiator. It did a fine job of blowing all that radiator heat, straight the radiator and into the gullets of my twin Quick Fuel 750s. They dyno a ton of camaros, stangs and vettes, all of which take their cold air low and from the front. The dyno has custom swing-out type fans that don't have the height and adjustability to feed cold air to a Cobra. I know I should have brought one of my portable centrifugal fans...
Looking at my highest standard number and figuring a Cobra customary 20% loss through the drivetrain (and exhaust) 475/0.80= 594 fwhp. Not too shabby I guess, considering...
