Roush 427 & 402 Differences

[madmaxx]

My Roush 427sr/tw idles all day at 850 rpm and drives very comfortably at anything above 1400 rpm's. Note there were carburator upgrades as they were developing the 427 so make sure you have the latest version!!! I THINK the latest carb edition has a green dot on it. I think most engines after Jan 08 should be good to go!!

Lude,
Now you can help me understand something: Is that like 820MPH at 10,000 or some fixed altitude level? What was the ride?
Hey, I'm hijacking your own thread!

Understanding & calculating airspeeds was always alot of "Fun" for me. Basically the speed of sound is dependent on the atmospheric temperature. As you rise in altitude, temperature drops (In STANDARD atmospheric conditions- ALOT of variables here tho). So the speed of sound will differ with altitude. At Sea Level its gonna be around 760 mph. We were at approx 18000 feet, so that magical sound barrier resides around 710 mph.
I was riding in an F-16D. Theres a pick in my photo album. We exceeded Mach 1.1 and bounced the G-meter past 8 on several attempts & past 9 a few times. Was unGodly Fun Logged 1.1 hours, forever burned into my cortex.

OK Lude, you da real deal. If you did not return previous meals at 9G you can handle a Twisted Wedge lil Cobra.
Thanks for the explaination-I knew there were many variables involved. It's OK to know that 1.1 is Friggen Fast. Now I'll test your patience one more time: Can you explain the "Block" designations of Eagles (and the other rocketship variants)-like "Block 50, Block 35, etc?
Must admit, I'm a closet Tomcat, Hornet and especially FLANKER freak. (I know, they're the bad guys...)

Block designations are like model years for cars, various changes & updates become standard with a new block. Of course, revisions are constant, especially when a platform is still in production, but the block designation gives the "owner" or maintainer a baseline of what is included. I believe the F-16 I rode in was a block 50 (newest at that time). The easiest way to tell was the the air intake was made MUCH larger to accommodate the bigger engines in the later variants. The intakes were big enough for several people to crawl inside. Big enough that I knew of one crew chief that got too close while the engine was running & got sucked in. His web belt got hung up on the vertical pitot inside the intake, and that was what saved his life. Some tools were sucked off his belt into the engine & shut it down.
I've Hijacked my own thread now.

Many thanks.

Flanker and FULCRUM were the names of some of my old computers , along with ; hornet .

now for old servers I had Hornet, Yorktown, Enterprise, and Lexington. --
