Updated my website with a dyno results page....

I'll see if Gary will give me the numbers. If I remember correctly though, he wouldn't let the operator pull the engine up as high as we did on the engine dyno, so the results will be skewed. Also, the carb was set up in the car so that the linkage wouldn't let it open up all the way. Gary found it later and noted that it felt like a completely different car at WOT.

I've seen dyno numbers vary from builder to builder. I know for a fact that one engine has been dyno'd on the dyno that I use and then was taken across town to a Superflow and showed 5% higher. You'll also see builders dyno at 120 deg water temp, where I try to dyno closer to 160-170, a temp that is closer to what the car will see, but isn't hot enough to cause issues under a full load.

I also really don't agree with comparing engine dyno numbers to chassis dyno numbers, especially in a Cobra. One member here (Excalibur) stuck his car on a chassis dyno, made a pull, then removed his side pipes and made 100 more RWHP. There can not be a direct correlation when golf-ball sized pipes are used, when restrictive air cleaners are used because of hood clearance, etc. All of those things play a big part in numbers, and if the engine wasn't dyno'd in the exact same setting, then it's bogus.
